    SUMMARY: The Food and Drug Administration (FDA) is announcing its 
    decision to authorize the use, on food labels and in food labeling, of 
    health claims on the association between sugar alcohols and the 
    nonpromotion of dental caries. The agency has concluded that, based on 
    the totality of the scientific evidence, there is significant 
    scientific agreement among qualified experts to support the 
    relationship between sugar alcohols (i.e., xylitol, sorbitol, mannitol, 
    maltitol, lactitol, isomalt, hydrogenated starch hydrolysates (HSH), 
    hydrogenated glucose syrups (HGS), or a combination of sugar alcohols) 
    and the nonpromotion of dental caries. Therefore, FDA has concluded 
    that claims on foods relating sugar alcohols to the nonpromotion of 
    dental caries are justified. FDA is announcing these actions in 
    response to a petition filed by the National Association of Chewing Gum 
    Manufacturers, Inc., and an ad hoc working group of sugar alcohol 
    manufacturers (hereinafter referred to as the petitioners).
    
    DATES: Effective January 1, 1998. The Director of the Office of the 
    Federal Register approves the incorporation by reference in accordance 
    with 5 U.S.C. 552(a) and 1 CFR part 51 of a certain publication in 21 
    CFR 101.80(c)(2)(ii)(C), effective January 1, 1998.

    SUPPLEMENTARY INFORMATION:
    
    I. Background
    
        In the Federal Register of July 20, 1995 (60 FR 37507), the agency 
    proposed to authorize the use, on food labels and in food labeling, of 
    health claims on the association between sugar alcohols and the 
    nonpromotion of dental caries. In addition, FDA proposed to exempt 
    sugar alcohol-containing foods from the requirement in 
    Sec. 101.14(e)(6) (21 CFR 101.14(e)(6)) of the health claims general 
    requirements regulation concerning disqualification criteria. Section 
    101.14(e)(6) provides that, except for dietary supplements or where 
    provided for in other regulations in part 101 (21 CFR part 101), 
    subpart E, to be eligible to bear a health claim, a food must contain 
    10 percent or more of the Reference Daily Intake (RDI) or the Daily 
    Reference Value (DRV) for vitamin A, vitamin C, iron, calcium, protein, 
    or fiber per reference amount customarily consumed before there is any 
    nutrient addition.
        -The proposed rule was issued in response to a petition filed under 
    section 403(r)(3)(B)(i) of the Federal Food, Drug, and Cosmetic Act 
    (the act) (21 U.S.C. 343(r)(3)(B)(i)). Section 403(r)(3)(B)(i) of the 
    act states that the Secretary of Health and Human Services (the 
    Secretary) (and, by delegation, FDA) shall promulgate regulations 
    authorizing health claims only if he or she determines, based on the 
    totality of publicly available scientific evidence (including evidence 
    from well-designed studies conducted in a manner which is consistent 
    with generally recognized scientific procedures and principles), that 
    there is significant scientific agreement, among experts qualified by 
    scientific training and experience to evaluate such claims, that the 
    claim is supported by such evidence (see also Sec. 101.14(c)). FDA 
    considered the relevant scientific studies and data presented in the 
    petition as part of its review of the scientific literature on sugar 
    alcohols and dental caries. The agency summarized this evidence in the 
    proposed rule (60 FR 37507).
        -The proposed rule included qualifying and disqualifying criteria 
    for the purpose of identifying foods eligible to bear a health claim. 
    The proposal also specified mandatory content and label information for 
    health claims statements and provided model health claims. In its 
    review of sugar alcohols eligibility for a health claim under 
    Sec. 101.14(b), FDA discussed potential safety issues relating to sugar 
    alcohols and the petitioners' position that the use of sugar alcohols 
    is safe and lawful. The agency also discussed the potential issue that 
    some sugar alcohol-containing foods may contain other ingredients, such 
    as refined flour, that may be cariogenic. Consequently, the agency 
    proposed to require that sugar alcohol-containing foods not lower 
    plaque pH below 5.7, as determined by appropriate in vivo tests. FDA 
    requested written comments on the proposed rule, including comments on 
    the agency's tentative conclusion that the petitioners had satisfied 
    the requirements regarding the safe and lawful use of sugar alcohols 
    that are the subject of the health claim and comments on the proposal 
    to establish a minimum plaque pH test for sugar alcohol-containing 
    foods.
    
    -II. Summary of Comments and the Agency's Responses
    
        -In response to the proposal, the agency received approximately 20 
    letters, each containing one or more comments, from professional 
    organizations, industry, trade associations, and health care 
    professionals. Comments that were not relevant to the sugar alcohol and 
    dental caries proposed rule, but that addressed broader issues 
    pertaining to health claims in general, are not discussed in the 
    sections of this document that follow.A number of comments were 
    received that dealt generally with the questions of whether health 
    claims need to state that the disease or health-related condition is 
    multifactorial, and whether the whole claim needs to appear in one 
    place. These issues of broad applicability to health claims are being 
    considered in the rulemaking entitled ``Food Labeling: Nutrient Content 
    Claims, General Principles; Health Claims, General Requirements and 
    Other Specific Requirements for Individual Health Claims'' (60 FR
    
    [[Page 43434]]
    
    66206, December 21, 1995) (hereinafter referred to as ``the 1995 
    nutrient content and health claims proposed rule''). Therefore, FDA 
    forwarded the comments in question to that docket for consideration as 
    part of that rulemaking.
        -The majority of the comments received in response to the sugar 
    alcohol proposal agreed with one or more provisions of the proposed 
    rule without providing grounds for support other than those provided by 
    FDA in the preamble to the proposal. A few of these comments also 
    requested modification of one or more provisions of the proposed rule. 
    A few comments disagreed with the proposed rule and provided specific 
    support for their positions. The agency has summarized and addressed 
    the relevant issues raised in all comments in the sections of this 
    document that follow.
    
    A. General Comments
    
        -Some comments addressed the basic issue of whether FDA should 
    permit health claims about sugar alcohol and dental caries on food 
    labeling and the claim's consistency with the general principles for 
    health claims.
        -1. One comment stated that section 403(r)(1)(B) of the act, which 
    was added by the Nutrition Labeling and Education Act of 1990 (the 1990 
    amendments), defines ``health claims'' as those statements that 
    characterize ``the relationship of any nutrient which is of the type 
    required [to be in nutrition labeling] of the food to a disease or a 
    health-related condition.'' The comment stated that in promulgating the 
    regulations governing health claims, FDA interpreted the statutory 
    language to include any relationship of a ``substance'' to a disease or 
    health-related condition (Sec. 101.14(a)(2)). The comment stated that 
    the agency used the term ``substance'' to make clear that health claims 
    could be established that described relationships regarding either 
    particular nutrients or foods bearing nutrients, such as fruits and 
    vegetables, and a disease or health related condition. The comment 
    stated that a health claim must describe the function of the substance 
    in question in providing nourishment or nutriment and how the function 
    of that nutrient relates to a disease or health condition. The comment 
    stated that the posited relationship between sugar alcohols and 
    noncariogenicity is not a nutrient relationship and does not satisfy 
    the nutrient-disease relationship requirement under the act because it 
    does not address the function of a substance in providing nourishment 
    or nutriment.
        -The agency does not agree that the proposed health claim is 
    inconsistent with health claim principles. Sugar alcohols are nutrients 
    of the type specified in section 403(q) of the act. FDA lists them in 
    Sec. 101.9(c) (21 CFR 101.9(c)) as one of the nutrients that can be 
    listed in the nutrition label. Thus, they can be the subject of a 
    health claim.
        -The issue of whether claims about sugar alcohols and dental caries 
    are health claims was discussed in the Federal Register of July 20, 
    1995 (60 FR 37502), final rule entitled ``Food Labeling: Label 
    Statements on Foods for Special Dietary Use; `Useful Only in Not 
    Promoting Tooth Decay' Disclaimer'' (hereinafter referred to as ``the 
    1995 disclaimer final rule''). The agency pointed out that a health 
    claim provides information about how a particular type of substance 
    (sugar alcohols) can affect a person's risk of developing a diet-
    related diseases (dental caries). The ``Useful Only in Not Promoting 
    Tooth Decay'' statement does what a health claim does in that it tells 
    a consumer that including foods sweetened with sugar alcohols in his or 
    her diet will affect his or her risk of developing dental caries.
        -Thus, in the 1995 disclaimer final rule, the agency found that the 
    statement on tooth decay is a health claim because it contains both 
    elements necessary to meet the ``health claim'' definition under 
    403(r)(1)(B) of the act. FDA concluded that ``useful only in not 
    promoting tooth decay'' is not a nutrient content claim because it does 
    not characterize the level of any nutrient. Thus, regardless of how 
    this claim has been used, as the law is now written, its use in food 
    labeling would misbrand the food unless claims about sugar alcohols and 
    dental caries are authorized by FDA under section 403(r)(3) (or section 
    403(r)(5)(D)) of the act.
        -Relative to the comment that a health claim must describe the 
    function of the substance in question in providing nourishment or 
    nutriment, the general principles for health claims do not require that 
    the health claim, itself, contain such a statement. The agency must be 
    fully satisfied, however, that the substance meets the general 
    requirements for health claims under Sec. 101.14, and under 
    Sec. 101.14(b)(3)(i), if the substance is consumed at other than 
    decreased dietary levels, it must contribute taste, aroma, or nutritive 
    value, or some technical effect listed in 21 CFR 170.3(o), to the food 
    and retain that attribute when consumed at levels that are necessary to 
    justify a claim. Sugar alcohols meet this requirement (see 60 FR 37507 
    and 37509) because they are used as sweeteners and bulking agents 
    (i.e., stabilizers and thickeners) and are consumed for their taste. 
    Inasmuch as sugar alcohols are also a source of calories, they 
    contribute nutritive value to the foods, such as chewing gums and 
    confectioneries, in which they are used.
        -2. One comment stated that the proposed claim is not a health 
    claim in the same sense that the other authorized claims are because 
    the substance's effect is largely independent of other dietary 
    practices, i.e., sugar alcohol-sweetened candy will always not promote 
    tooth decay regardless of other elements in the diet. Another comment 
    stated that the idea of instituting a health claim for a substance that 
    merely replaces a nutrient that may contribute to a disease or health-
    related condition could open the door to questionable claims. One 
    comment stated that the nonpromotion claim is a product descriptor that 
    provides information on the absence of an undesirable side effect.
        -The agency disagrees that the claim is not valid because sugar 
    alcohols function independently of other dietary practices, or because 
    the substance replaces or can substitute for another substance. The 
    comment did not demonstrate that sugar alcohols affect the risk of 
    dental caries in a way that is independent of other dietary practices, 
    or why, even if the did, this fact would render the claim invalid. In 
    fact, as explained in the proposed rule (60 FR 37507 at 37524), the 
    association between sugar alcohols and dental caries is related to 
    dietary practices. The consumption of dietary sugars and fermentable 
    carbohydrates in the form of gums, confectioneries, and other snack 
    foods is widespread and frequent in the diet. There is a clear 
    association between the onset of dental caries and the presence in the 
    diet of sugars and other fermentable carbohydrates. By consuming foods, 
    such as gums, mints, candies, jams and jellies, and desserts, in which 
    sugar alcohols are used to replace the fermentable carbohydrates 
    instead of the versions of those foods that contain the fermentable 
    carbohydrates, the consumer, the available evidence shows, reduces his 
    or her risk of developing dental caries. Therefore, the claim is based 
    on dietary practices and is relevant within the context of the total 
    daily diet.
        -A claim based on the substitution or replacement of one food 
    substance for another is not inconsistent with, or prohibited under, 
    the general principles for health claims. In fact, current dietary 
    recommendations encourage substitution and replacement of foods in the 
    diet, for example, the use of low-fat foods in place of high-fat foods.
    
    [[Page 43435]]
    
    However, the evidence must show that the effect of substituting one 
    substance for another is relevant to the risk of the disease or health-
    related condition that is the subject of the claim. Here, the results 
    of long-term studies in which sugar alcohol-containing foods are 
    substituted for sugar-containing foods in the daily diet support the 
    contention that sugar alcohols help reduce the risk of developing 
    dental caries (see, for example, Refs. 21, 22, 23, and 25; 60 FR 37507 
    at 37514).
        -The concern in one comment that questionable claims may occur when 
    the substitution or replacement of substances is the subject of a 
    health claim is fully addressed by the provisions of existing 
    principles for health claims. One of the requirements for a substance 
    to be eligible for a health claim is that the substance must be 
    associated with a disease, or health-related condition, or, 
    alternatively, the petition must explain the prevalence of the disease 
    in the U.S. population and the relevance of the claim in context of the 
    total daily diet (see Sec. 101.14(b)(1)). The agency finds that this as 
    well as the other eligibility requirements for health claims provide 
    protection against questionable claims.
        -3. A comment stated that in the preamble to the ``General 
    Requirements for Health Claims for Food'' final rule (58 FR 2478, 
    January 6, 1993), FDA limited the application of the health claims 
    rule, based upon review of the 1990 amendments legislative history. The 
    comment stated that the agency supported limiting the type of disease 
    relationships that would be subjected to the health claim regime with 
    the following rationale: ``In the legislative history, Congress focused 
    only on those health claims that related to chronic disease, such as 
    cancer, heart disease, and osteoporosis'' (58 FR 2478 at 2481). The 
    comment stated, therefore, that dental caries are not the type of 
    ``chronic disease'' Congress intended to be regulated as a health claim 
    since dietary choices will have less of an impact on tooth decay than 
    will numerous other factors (e.g., fluoridation of water supply). 
    Additionally, several comments alleged that dental caries is in decline 
    in this country and suggested that this trend justifies not finalizing 
    the proposed health claim.
        - The statement within the preamble to ``General Requirements for 
    Health Claims for Food'' final rule (58 FR 2478 at 2481) referred to in 
    the comment was part of a discussion about applicability of health 
    claims to classical deficiency nutrient diseases and was not a 
    discussion on limiting claims to chronic diseases. Nowhere in that 
    document did the agency state that the diet/disease relationships that 
    could be the subject of a health claim were those that involved chronic 
    diseases. Moreover, section 403(r)(1)(B) of the act itself does not 
    limit the Secretary's authority to regulate health claims to those 
    pertaining to chronic diseases. In fact, the agency has recently 
    authorized a health claim pertaining to a disease that would generally 
    not be considered to be a chronic disease, neural tube defects.
        -As made clear in Sec. 101.14(a)(6), the agency focuses on whether 
    the disease in question, in this case dental caries, constitutes damage 
    to an organ, part, structure, or system of the body such that it does 
    not function properly. As outlined in the proposal, the agency 
    tentatively concluded that dental caries meets this criterion (60 FR 
    37507 at 37509 through 37510), and the comments have presented no 
    evidence to support a different conclusion. Further, dental caries is a 
    disease for which the general U.S. population, or an identified 
    subgroup, is at risk, and the condition is prevalent in the general 
    population (see Sec. 101.14(b)(1)).
        -Although the overall incidence of dental caries has declined in 
    the United States, as mentioned in some comments, dental caries is 
    still a public health issue. The disease remains one of the most 
    prevalent infectious diseases that causes substantial expense, pain, 
    and work loss (Ref. 89). There is evidence showing no decline in dental 
    caries in some tooth surfaces, i.e., occlusal and proximal tooth 
    surfaces, and a substantial subset of children continue to exhibit a 
    high incidence of tooth decay (Ref. 95). In addition, little is known 
    about present trends in oral health in the older population. There are 
    some studies that suggest that the caries incidence in adults is 
    considerable (Ref. 95). Consequently, dental caries continues to be a 
    disease of public health concern in this country.
        -4. Three comments stated that the proposed sugar alcohol health 
    claim promotes a good food/bad food dichotomy, based on whether the 
    food contains sugar alcohols. One comment stated that the proposed 
    health claim suggests that foods not eligible to bear the claim will 
    automatically contribute to tooth decay. One comment stated that the 
    health claim fails to promote health objectives. The comment also 
    stated that children should focus on a balanced diet over time for 
    proper growth and development rather than on the consumption of a 
    particular ingredient. It stated that most sugar alcohol products 
    contain little or no calories, micronutrients, or macronutrients, and 
    yet they may be eaten in lieu of foods that can contribute real 
    nutrients to the diet. The comment stated that FDA should not be 
    promoting products that are devoid of nutrition in lieu of products 
    that provide the energy and the nutrients children need.
        -FDA disagrees that foods ineligible to bear a health claim will be 
    perceived by consumers as bad for the health. The comment did not 
    present any evidence to show that consumers interpret the absence of a 
    health claim on food labels as evidence that the food is not healthful. 
    For example, the agency has authorized a fat and heart disease claim, 
    but the comment provided nothing to suggest that consumers believe that 
    a food product that does not bear this health claim will promote heart 
    disease.
        -FDA disagrees also that the health claim fails to promote health 
    objectives and promotes consumption of a particular nutrient rather 
    than focusing on a balanced diet. As stated above, dental caries 
    remains a public health concern. Foods that meet the criteria for this 
    health claim contribute to public health objectives because they do not 
    promote tooth decay.
        -The comment did not provide any evidence to show that this health 
    claim will focus the consumer's attention on one nutrient rather than 
    on a balanced diet. The claim identifies a special characteristic of 
    the food that is recognized to bear on the occurrence, and affect the 
    risk, of a disease, dental caries. For those interested in reducing 
    their risk of this disease, the claim serves to inform them, as claims 
    of this type have done for almost 20 years, of this special 
    characteristic.
        -The agency also disagrees with the comment that this health claim 
    will promote for children foods that are devoid of nutrition. Claims 
    for sugar alcohols, unlike claims for fruits, vegetables, and grain 
    products and heart disease authorized under 21 CFR 101.77, for example, 
    do not encourage increased consumption of foods to help reduce disease 
    risk. Rather, sugar alcohol claims simply state that to the extent 
    these foods are consumed as substitutes for foods that contain 
    fermentable carbohydrates, they may help reduce the risk of dental 
    caries. These claims in no way suggest adjustment in the consumption of 
    sugar alcohol-containing foods, and to the extent they have such an 
    effect, it would be limited to the class of foods that contain 
    sweeteners. Given the small effect, if any, that the claim will have on 
    the broad range of dietary choices that people make, FDA finds no merit 
    to this comment.
    
    [[Page 43436]]
    
        -5. Some comments stated that the focus on sugar alcohols in the 
    proposed claim will detract from proper dental care, although they 
    provided no evidence to support this contention. One comment stated 
    that a health claim associated with these products may result in a 
    decrease in oral health practices of much greater importance to dental 
    health than diet, i.e., brushing, flossing, fluoride treatments, and 
    professional dental care, including application of dental sealants and 
    prophylaxis. The comments stated that the claim should discuss the 
    importance of proper oral hygiene and dental care, including the use of 
    fluoride toothpaste daily.
        -FDA does not agree that the proposed health claim will detract 
    from proper dental care. As discussed in the proposed rule and as 
    mentioned in some of the comments, the incidence of dental caries has 
    declined over the past 20 years. Coincidentally, the claim ``useful 
    only in not promoting tooth decay'' has been used for almost 20 years 
    on sugar alcohol-containing chewing gums and confectioneries. Based on 
    the historical use of these products and the decline in dental caries, 
    there is no reason to conclude that the use of this claim has taken 
    away from proper dental care. Further, the claim is consistent with 
    public health recommendations.
        -However, the agency agrees that information about proper oral 
    hygiene and dental care as part of good dental health practices may be 
    useful to consumers of sugar alcohol products. This information is 
    consistent with information provided in ``The Surgeon General's Report 
    on Nutrition and Health'' (hereinafter referred to as the Surgeon 
    General's report) (Ref. 7). Therefore, the agency has been persuaded to 
    include this type of information among the types of optional 
    information that a manufacturer may provide as part of the health 
    claim. Section 101.80(d)(3) (21 CFR 101.80(d)(3)) provides that the 
    claim may state that oral hygiene and proper dental care may help to 
    reduce the risk of dental caries.
    
    B. Safety Issues
    
        -In its proposal, the agency noted that several of the sugar 
    alcohols that are the subject of this proceeding are listed in FDA's 
    food additive and generally recognized as safe (GRAS) regulations, 
    i.e., xylitol (Sec. 172.395 (21 CFR 172.395)), mannitol (Sec. 180.25 
    (21 CFR 180.25)), and sorbitol (Sec. 184.1835 (21 CFR 184.1835)) (see 
    60 FR 37507 at 37509). In addition, it stated that GRAS affirmation 
    petitions have been submitted for each of the remaining substances, 
    i.e., maltitol (GRASP 6G0319), maltitol syrups (HGS syrups) (GRASP 
    3G0286), isomalt (GRASP 6G0321), lactitol (GRASP 2G0391), HSH (GRASP 
    5G0304), and HSH syrups (GRASP 1G0375). The agency stated that these 
    GRAS affirmation petitions are under consideration, and that any 
    positive action resulting from the proposed rule should not be 
    interpreted as an indication that the agency has affirmed that the 
    general food uses of the sugar alcohols according to their respective 
    petitions are GRAS. FDA stated that such determinations can only be 
    made after the agency has completed its review of each respective GRAS 
    petition. Nonetheless, the agency stated that a preliminary review of 
    the GRAS affirmation petitions had revealed that they contain 
    significant evidence supporting the safety of these substances, but 
    that some concerns about the safety of sugar alcohols do exist. The 
    agency also stated that two of the sugar alcohols that are listed in 
    FDA's food additive and GRAS regulations, i.e., mannitol (Sec. 180.25) 
    and sorbitol (Sec. 184.1835), require a warning label regarding 
    laxation if daily consumption is expected to exceed 20 grams (g) per 
    day for mannitol and 50 g per day for sorbitol. FDA stated that nothing 
    in the proposed rule would alter these requirements.
        -The agency stated that based on the totality of the evidence, it 
    was not, at this time, challenging the petitioners' position that the 
    use of the enumerated sugar alcohols is safe and lawful. Although FDA 
    tentatively concluded that the petitioners satisfied the requirements 
    of Sec. 101.14(b)(3)(ii), the agency requested comments on its 
    tentative conclusion.
        -6. Two comments noted that the Joint Food and Agriculture 
    Organization/World Health Organization (FAO/WHO) Expert Committee on 
    Food Additives (JECFA) has reviewed the safety data on these sugar 
    alcohols and concluded that their use is safe, with no need for 
    restriction other than good manufacturing practices. One of these 
    comments stated that there is sufficient documentation to support a 
    general recognition of safety.
        -Three comments stated that sugar alcohols can pose health 
    problems, citing specifically the well-known gastrointestinal 
    disturbances, such as stomach pain and diarrhea, that can result from 
    excessive consumption. One of these comments also noted safety issues 
    raised regarding animal data that associate consumption of large 
    amounts of sugar alcohols with adrenal medullary hyperplasia and 
    pheochromocytomas. The comment noted that JECFA will be reviewing these 
    issues in 1996. (The agency notes that the report from the February 
    1996 meeting is not yet available.) While these comments opposed 
    indiscriminate promotion or consumption of sugar alcohol-sweetened 
    foods, they did not argue that such ingredients were not safe or lawful 
    as ordinarily used.
        -The agency concludes that these comments, taken together, 
    accurately reflect the current understanding of the safety of sugar 
    alcohols. They do not, however, provide a basis for the agency to 
    reject the petitioners' position that the use of sugar alcohols is safe 
    and lawful or for invoking warnings in addition to those already 
    required. Therefore, the agency concludes that the requirements of 
    Sec. 101.14(b)(3)(ii) are satisfied.
    
    C. Exemption from Sec. 101.14(e)(6)
    
        -Under proposed Sec. 101.80(c)(1), sugar alcohol containing foods 
    must meet the requirements in Sec. 101.14, except that sugar alcohol-
    containing foods are exempt from Sec. 101.14(e)(6), the requirement 
    that foods making health claims contain 10 percent or more of the RDI 
    or the DRV for vitamin A, vitamin C, iron, calcium, protein, or fiber 
    per reference amount customarily consumed before any nutrient addition.
        -7. One comment asked for clarification that this exemption applied 
    to all sugar alcohol-containing confectioneries, and not just to 
    chewing gum, hard candies, and mints.
        -FDA notes that the exemption applies to all sugar alcohol- 
    containing foods. The agency did not specifically limit the exemption 
    to chewing gum and confectioneries. Because sugar alcohols function as 
    sweeteners, their use has been as replacements for simple and complex 
    sugars. Sugar alcohols provide a sweet taste and serve as bulking 
    agents and, consequently, are used only in certain product categories. 
    However, these food categories are sufficiently diverse as to make 
    specific definitional criteria difficult. For this reason, FDA has not 
    limited the exemption to specific foods. However, the agency wishes to 
    point out that a food must still meet all of the other requirements in 
    Sec. 101.80(c)(2)(ii) to be eligible to bear the claim.
        -8. Two comments that agreed with FDA's tentative decision to 
    exempt sugar alcohol-containing foods from Sec. 101.14(e)(6) requested 
    that sugar alcohol-containing products also be exempt from the 
    requirement of Sec. 101.14(e)(3) relating to foods with disqualifying 
    levels of fat, saturated fat, cholesterol, or sodium. One comment
    
    [[Page 43437]]
    
    stated that the agency has authority to grant exemptions from this 
    requirement when a health claim will assist consumers in maintaining 
    healthy dietary practices. The comment stated that an exception is 
    warranted because the health claim will assist consumers in making 
    decisions relating to dental health in all contexts in which the claim 
    is used. The comments stated that the presence of high levels of fat, 
    saturated fat, cholesterol, or sodium does not conflict with the health 
    message because these nutrients are not adversely associated with 
    dental health.
        -FDA has established different disqualifying levels for different 
    categories of foods, depending on the role that they play in the daily 
    diet. Section 101.14(a)(5) defines the disqualifying level for 
    individual foods as 20 percent of the Daily Values (DV's) for total 
    fat, saturated fat, cholesterol, and sodium. These levels translate to 
    13.0 g of total fat, 4 g of saturated fat, 60 milligrams (mg) of 
    cholesterol, and 480 mg of sodium per reference amount customarily 
    consumed, per labeled serving size, and, for foods with reference 
    amounts customarily consumed of 30 g or less or 2 tablespoons or less, 
    per 50 g. The regulations also make additional allowances for main dish 
    products and meal-type products (see Sec. 101.14(a)(5)(i) and (ii)).
         -A food that exceeds the disqualifying level for any of the four 
    disqualifying nutrients may not bear a health claim unless the agency 
    has granted an exemption ``based on a finding that such a claim would 
    assist consumers in maintaining healthy dietary practices'' (section 
    403(r)(3)(A)(ii) of the act).
        -The comment requesting the exemption of sugar alcohol-containing 
    foods from the disqualifying levels provided no evidence to demonstrate 
    that the presence of the claim on foods containing high levels of fat, 
    saturated fat, cholesterol, or sodium will benefit consumers other than 
    to suggest that the claim would appear on more foods. This rationale is 
    not consistent with the basic notion that it makes no sense to include 
    a health claim in the labeling of a food that contains other nutrients 
    at a level that increases the risk of other diseases unless a clear 
    benefit for consumers can be demonstrated (see 58 FR 2478 at 2489 to 
    2490).
        -In ``the 1995 nutrient content and health claims proposed rule,'' 
    FDA has considered the instances where disclosure rather than 
    disqualification may be appropriate and discussed these in this 
    proposal to amend its regulations on nutrient content and health claims 
    to provide additional flexibility in the use of these claims on food 
    products. FDA highlighted factors that it would consider in deciding 
    whether to exempt a food from disqualification, including the level of 
    public health importance, the availability of foods that qualify for a 
    health claim, and evidence that the population the claim targets is not 
    at risk for the disease associated with the disqualifying nutrients. It 
    stated that exceptions to Sec. 101.14(e)(3) should be granted on a 
    case-by-case basis, using a petition process. It also proposed new 
    Sec. 101.70(f) (21 CFR 101.70(f)) to provide guidance for petitioners 
    requesting an exception to the prohibition in Sec. 101.14(e)(3) of 
    health claims for foods exceeding the disqualifying levels identified 
    in Sec. 101.14(a)(5) (see 60 FR 66206 at 66224).
        -The comment did not submit any information of the type that FDA 
    needs as the basis for an exemption. In the absence of such 
    information, FDA finds that it cannot conclude that the population at 
    risk for dental caries is not at risk, for example, for heart disease. 
    The agency is therefore denying the request to exempt sugar alcohol-
    containing foods from the disqualifying levels established in 
    Sec. 101.14(a)(5).
    
    D. Relationship Between Sugar Alcohols and Dental Caries
    
        -9. Some comments stated that in the proposal the agency had 
    correctly identified the interaction between sugars and other 
    fermentable carbohydrates and oral bacteria in the development of 
    dental caries. However, these comments stated that the proposed health 
    claim puts undue emphasis on sugars and sucrose in the causation of 
    dental caries. The comments stated that the dental community is 
    unanimous in the view that all fermentable carbohydrates, not just 
    sugars, have the potential to contribute to tooth decay. One comment 
    stated that to the extent that dietary factors play a role in caries, 
    the most important factor is frequency of consumption of fermentable 
    carbohydrates and not consumption per se. One comment quoted the report 
    of the Dietary Guidelines Advisory Committee on the Dietary Guidelines 
    for Americans, 1995 (Ref. 101) which states:
    
        -[B]oth sugars and starches can promote tooth decay. The more 
    often you eat foods that contain sugars and starches, and the longer 
    these foods are in your mouth before you brush your teeth, the 
    greater the risk for tooth decay. Thus, frequent eating of foods 
    high in sugars and starches as between-meal snacks may be more 
    harmful to your teeth than eating them at meals and then brushing.
    
        -FDA agrees that all fermentable carbohydrates, including sugars 
    and starches, can promote tooth decay. As stated in the recently 
    revised Dietary Guideline for Americans (Ref. 101), both the frequency 
    of consumption and the duration of exposure of teeth to sugars and 
    starches contribute to the risk of dental caries. However, the agency 
    points out that, as outlined in the proposal, the basis for the 
    proposed claim centers around the use of sugar alcohols in place of 
    sugars. Sugar alcohols cannot be used in place of all fermentable 
    carbohydrates. Rather, sugar alcohols function as sweeteners and 
    bulking agents, and their use is primarily in the manufacture of gums 
    and confectioneries. Moreover, the significance of the claim in the 
    context of the total daily diet is based upon: (1) The presence in the 
    diet of foods sweetened with simple and complex sugars, and (2) the 
    fact that sugar alcohols, because of their very low fermentability, 
    when substituted for other sugars, do not promote dental caries.
        -Nonetheless, the agency agrees that it would be helpful to 
    consumers to be informed about the overall role of fermentable 
    carbohydrates in the diet and thus is persuaded to revise 
    Sec. 101.80(a)(2) and (a)(4) to reflect that all fermentable 
    carbohydrates, i.e., sugars and starches, are cariogenic and to include 
    in these paragraphs information about dental caries provided in Dietary 
    Guidelines for Americans (Ref. 101). In proposed Sec. 101.80(a)(2), the 
    agency described the relationship between dietary sugars and tooth 
    decay, that is how bacteria metabolizes sugar, causing acid and forming 
    plaque. This was followed by a statement that the dental plaque results 
    in more acid that deminarilizes enamel after prolonged exposure. The 
    final statement was a precaution then, that between-meal consumption of 
    sugary foods would cause more tooth decay. In this document, the agency 
    is changing Sec. 101.80(a)(2) to include the relationship between 
    consumption of fermentable carbohydrates and starches, as well as 
    dietary sugars, to tooth decay. The last sentence states that ongoing 
    exposure to starches, as well as dietary sugars, increases the risk for 
    tooth decay.
        -The agency notes that sucrose is still considered the most 
    cariogenic sugar, and that this substance has been shown to promote the 
    growth of plaque more than other sugars (Ref. 71). Therefore, the 
    agency is highlighting, and permitting the use of the statement 
    regarding, the cariogenicity of sucrose. In addition, consistent with 
    Sec. 101.4(b)(20), the term ``sugar'' may be used as a synonym for 
    ``sucrose.''
    
    [[Page 43438]]
    
        -The agency is also revising Sec. 101.80(a)(4) to state that sugar 
    alcohols can be used as sweeteners to replace dietary sugars, such as 
    sucrose and corn sweeteners, in foods such as chewing gums and 
    confectioneries, and that they are significantly less cariogenic than 
    dietary sugars and other fermentable carbohydrates. The agency is 
    adding the statement regarding ``corn sweeteners'' to reflect the fact 
    that sugar alcohols are used to replace more than sucrose in chewing 
    gums and confectioneries, and that they are used primarily as 
    sweeteners. The agency is deleting the statement, ``Thus, replacing 
    dietary sugars with sugar alcohols helps to maintain dental health,'' 
    from Sec. 101.80(a)(4) because it is a statement of the significance of 
    the relationship between sugar alcohols and dental caries which is 
    addressed in Sec. 101.80(b). Consequently, this statement is 
    superfluous in Sec. 101.80(a). The agency concludes that, with the 
    above revisions, Sec. 101.80(a)(2) and (a)(4) accurately reflect the 
    relationship between fermentable carbohydrates and dental caries and 
    are not misleading as to the role of sugar alcohols in not promoting 
    tooth decay.
         -The agency is also deleting proposed Sec. 101.80(d)(2), which 
    permitted use of the term ``sugar'' or ``sucrose'' when referring to 
    sucrose. Since Sec. 101.80(d)(1) allows the claim to include 
    information from Sec. 101.80(a), and Sec. 101.80(a)(2) has been revised 
    to include ``sugar'' as a synonym for ``sucrose,'' Sec. 101.80(d)(2) is 
    repetitive and unnecessary. As a result of this action, proposed 
    Sec. 101.80(d)(3) is being redesignated as Sec. 101.80(d)(2). FDA is 
    also adding in new Sec. 101.80(d)(3) information regarding the 
    importance of proper dental care in response to the comments discussed 
    in comment 5 of this document.
        -10. Some comments stated that the agency's emphasis in the 
    proposal on sticky foods as a factor in dental caries was inaccurate. 
    One comment stated that more recent scientific evidence does not 
    support the relationship between foods that easily stick to teeth and 
    dental caries. The comment included a study to support this assertion. 
    The comment stated that the high starch and low sugar foods are 
    retained on teeth longer than high sugar and low starch foods. One 
    comment stated that a health claim statement about foods that easily 
    stick to teeth is misleading and could drive consumers towards 
    erroneous food choices in the interest of avoiding what they think are 
    sticky foods.
        -The agency concurs that the evidence submitted suggests that the 
    degree of stickiness of a food, as perceived subjectively by the 
    consumer, does not correlate with the actual retention of the food on 
    human dentition in vivo (Refs. 92 and 93). Therefore, the agency is 
    deleting reference to sticky foods in Sec. 101.80(a)(2).
        -11. Several comments disagreed with the statements that U.S. diets 
    tend to be high in sugars, and that government organizations recommend 
    decreased consumption of sugars. The comments stated that FDA's 1986 
    Sugars Task Force report (Ref. 94) concluded that the average daily 
    intake for added sugars accounted for 11 percent of the daily calorie 
    intake for the total population. One comment stated that this amount 
    approximates the amount (10 percent) recommended by the Select 
    Committee on Nutrition and Human Needs in its second edition of Dietary 
    Goals for the United States (1977) (Ref. 100). The comments stated that 
    current dietary guidelines advise that sugars be used only in 
    moderation but not restriction of sugars consumption. One comment 
    stated that the proposed health claim implicates sugars as a diet and 
    disease concern, which will mislead consumers as to the health 
    significance of sugar consumption.
        -FDA agrees that the focus of dietary guidance for the general 
    population is to choose a diet moderate in sugars and to avoid 
    excessive snacking (Ref. 101). Therefore, FDA has modified 
    Sec. 101.80(a)(3) to delete statements regarding the sugars consumption 
    in the American diet and dietary recommendations to reduce sugars 
    intake. In their place, FDA has included information from the recent 
    Dietary Guidelines for Americans (Ref. 101) in Sec. 101.80(a)(3), which 
    states that dental caries is still widespread in the United States 
    creating a burden on Americans. The government's dietary guidelines 
    suggest selecting diets with moderation in sugars and avoidance of 
    excessive snacking. Because snacks rich in sugars and starches may 
    result in a greater incidence of tooth decay since they are less likey 
    to be followed by brushing.
        -The agency disagrees with the comment that the health claim will 
    mislead consumers as to the health significance of sugars consumption. 
    Sugars consumption has long been associated with risk of dental caries, 
    and information reflecting this fact is a common component of public 
    health education efforts. Moreover, as a result of the changes that FDA 
    has made, Sec. 101.80(a)(2), (a)(3), and (a)(4) accurately reflect the 
    relationship that exists among sugar alcohols, dietary sugars and other 
    fermentable carbohydrates, and dental caries. Thus, there is less 
    chance that consumers could be misled. In light of these changes, the 
    agency has revised the title of Sec. 101.80(a) to more accurately 
    reflect the contents of this paragraph. The revised title is 
    ``Relationship between dietary carbohydrates and dental caries.''
        -12. Some comments stated that there is no indication that a sugar 
    alcohol and dental caries health claim will have any impact on sugars 
    consumption or on the incidence of dental caries in the U.S. 
    population. The comments stated that sugars consumption remained stable 
    from 1977 to 1988, and that dental caries decreased during that time. 
    One comment stated that dietary counseling, to the general public, on 
    sugar consumption is an ineffective caries prevention technique. The 
    comment stated that dietary guidelines do not advocate the reduction in 
    sugars in the diet as a means to lower the incidence of dental caries.
        -The intent of the health claim is to provide consumers with public 
    health information that will enable them to make dietary choices that 
    can affect their risk of dental disease. Dental caries are recognized 
    as an important and widespread public health problem in the United 
    States. Although dental caries among children are declining, the 
    overall prevalence of the condition imposes a substantial economic 
    burden because of the health care costs associated with care for this 
    condition. In addition, as discussed in section II.A. of this document, 
    there is evidence to show that the decline in dental caries may not 
    apply to all tooth surfaces, and that a substantial subset of children 
    continue to exhibit a high incidence of tooth decay (Ref. 94). In 
    addition, little is known about trends in oral health in the older 
    population. There are some studies that suggest that the caries 
    incidence in adults is considerable (Ref. 95). Until means of 
    preventing dental caries are available to the entire U.S. population, 
    dietary counseling is an important element of dental care (Ref. 95).
        -The sugar alcohol-containing foods that have used this dental 
    caries claim over the past 20 years have primarily been snack foods, 
    i.e., chewing gums and confectioneries. Snack foods are a part of the 
    diets of many Americans. As stated in the recent Dietary Guidelines for 
    Americans (Ref. 101), frequent between-meal snacks that are high in 
    sugars and starches may be more harmful to teeth than eating the same 
    foods at meals and then brushing. Therefore, chewing gums and 
    confectioneries that contain sugar alcohols but no fermentable 
    carbohydrates provide an alternative
    
    [[Page 43439]]
    
    food choice for those consumers who enjoy sweetened snack foods yet are 
    interested in dental health.
        -The comments incorrectly suggest this health claim is intended to 
    imply that sugar alcohol-containing foods will prevent dental caries. 
    The agency wishes to highlight the difference between a prophylactic 
    effect and a nonpathologic effect. The proposed claim does not state 
    that sugar alcohols provide a prophylactic benefit, i.e., the claim is 
    not that they will prevent tooth decay. Rather, the claim states that 
    sugar alcohols do not promote dental caries. The evidence supports a 
    beneficial role of sugar alcohols in the absence of other carbohydrates 
    in maintaining plaque pH above a level that promotes enamel 
    demineralization.
    
    E. Significance of the Relationship Between Sugar Alcohols and Dental 
    Caries
    
        -Under proposed Sec. 101.80(b), the agency stated that sugar 
    alcohols do not promote dental caries because they are slowly 
    metabolized by bacteria to form some acid. The rate and amount of acid 
    production from sugar alcohols is significantly less than that from 
    sucrose, and therefore consumption of sugar alcohols does not cause the 
    loss of minerals from tooth enamel.
        -13. Some comments argued that there is scientific evidence to show 
    that oral bacteria can adapt to sorbitol, thus making it cariogenic. 
    One comment stated that there is considerable debate over the potential 
    for an adaptive shift in the oral ecology in response to the 
    consumption of sugar alcohols, specifically that plaque bacteria may 
    adapt to xylitol, thus making it potentially cariogenic.
        -FDA notes that the fermentability of sorbitol and other sugar 
    alcohols, in human and animal models and in vitro, was discussed in the 
    proposed rule (60 FR 37507) and has been reviewed in a number of 
    published articles (Refs. 95 to 99 and 102). This information shows 
    that fermentation of sorbitol proceeds at a slow rate, with a final pH 
    remaining above the low pH levels achieved with glucose or sucrose.
        -In vitro studies have shown that dental plaque, when incubated 
    with sorbitol, did not produce enough acid to cause enamel 
    decalcification. Some investigators note, however, that it may be very 
    misleading to extrapolate from an in vitro pure culture situation to 
    that of a mixed microbial community in vivo (Ref. 102).
        -In addition to the fact that the use of a purified culture does 
    not reflect a normal mix of the types of oral bacteria, the results of 
    in vitro studies that showed acid production from sorbitol after a 
    prolonged period of incubation (22 hours) have little relevance to the 
    in vivo situation. In vivo studies have shown that plaque pH drops only 
    marginally after consumption of sorbitol-containing foods (Ref. 95). 
    Moreover, plaque pH telemetry tests have been used to assess the 
    acidogenic potential of sorbitol on plaque in situ (Ref. 95). These 
    tests have demonstrated consistently that the consumption of sorbitol 
    is not associated with an acidification of dental plaque that would 
    suggest cariogenic risk.
        -As discussed in the proposed rule (60 FR 37507 at 37523), there is 
    evidence that suggests that long-term, uninterrupted consumption of 
    sorbitol results in adaptation by oral bacteria and, therefore, in more 
    acid production. However, microbiological studies have shown that the 
    final pH obtained after long-term exposure to sorbitol remained above a 
    plaque pH level associated with cariogenic risk (Ref. 96, 98, 99, and 
    102), and that pre- and post-adaptation rates of acid production from 
    sorbitol in vitro are very similar and very low compared to glucose 
    (Ref. 102). Additionally, adaptation is inhibited in the presence of 
    glucose, as bacterial metabolism preferentially switches to the 
    metabolic substrate that is more readily used as an energy source 
    (Refs. 46, 95, and 60 FR 37507 at 37512). At the same time that 
    bacteria switch to glucose as the preferred energy source, the 
    mechanism that enables them to metabolize sorbitol is repressed (Ref. 
    95).
        -Bacteria in plaque may also show some level of adaptation to long-
    term exposure to mannitol (Ref. 97). As with sorbitol, however, the 
    amount of acid produced from bacterial metabolism of mannitol is small 
    and very slow compared to bacterial metabolism of glucose. The study 
    results showed that final plaque pH levels in situ did not drop to 
    levels that demineralized dental enamel (Ref. 97).
        -In response to the comment that plaque bacteria may adapt to 
    xylitol, thus making it potentially cariogenic, the agency notes that 
    some in vitro studies have isolated plaque microorganisms capable of 
    metabolizing xylitol. Incubating certain strains of bacteria over 
    prolonged time showed increased acid production from xylitol (Ref. 97). 
    The amount of acid produced, however, was very small and has not been 
    shown to promote dental enamel demineralization. There is no evidence 
    to show that adaptation to xylitol is maintained when plaque bacteria 
    are exposed to other fermentable carbohydrates in the daily diet.
        -The agency concludes, based on the evidence, that frequent or 
    long-term use of sugar alcohols, especially in the context of a daily 
    diet that contains other carbohydrates that are preferentially 
    metabolized by oral bacteria, may result in some adaptation by the 
    bacteria in plaque to these substances. The effect, however, would not 
    be such that consumption of sugar alcohols would contribute in any way 
    to the risk of dental caries in the general population.
    
    F. Nature of Claim and Optional Information
    
        -In Sec. 101.80(c)(2)(i), the agency proposed specific requirements 
    on the nature of the claim, including the use of statements such as 
    ``does not promote,'' ``useful in not promoting,'' or ``expressly for 
    not promoting'' dental caries. In Sec. 101.80(c)(2)(i)(C), FDA 
    proposed, that for packages with a total surface area available for 
    labeling of 15 or more square inches, the claim state that dental 
    caries depends on many factors.
        -14. Several comments stated that the proposed regulation should 
    require that the labeled claim identify other dietary factors that are 
    associated with dental caries. One comment stated that the claim should 
    allude to the role of all fermentable carbohydrates in the development 
    of dental caries, although the comment did not provide data to show 
    that the term ``fermentable carbohydrates'' is meaningful to consumers. 
    Other comments emphasized the importance of addressing issues related 
    to frequent consumption of fermentable carbohydrates.
        -Issues related to providing information about dietary factors are 
    relevant to the requirement that the claim enable the public to 
    understand the significance of the information in the context of a 
    total daily diet (section 403(r)(3)(B)(iii) of the act). Therefore, in 
    considering these comments, the agency reviewed the dietary context in 
    which the claim would be presented. While the claim for sugar alcohols 
    is about the effect of using them to replace dietary sugars, the agency 
    is persuaded that the claim should include information to set the 
    message within the broader context of fermentable carbohydrates so as 
    to provide overall dietary information potentially beneficial to 
    consumers. It is well accepted that the relationship between diet and 
    the development of dental caries is based on the interaction between 
    oral bacteria and the presence of substances that support the growth 
    and development of these bacteria, especially the bacteria in plaque, 
    and on the production of acid in dental plaque.

    As noted in several of the comments, it is also well accepted that 
    dietary carbohydrates, such as dietary sugars and starches, are readily 
    fermented by oral bacteria and can promote the growth and development 
    of these bacteria.
        -Further, in its review of the scientific evidence in the proposal 
    (60 FR 37507), the agency tentatively concluded that, in the absence of 
    other fermentable carbohydrate-containing foods, sugar alcohol-
    containing foods did not promote dental caries because they do not 
    lower plaque pH to the level associated with enamel demineralization. 
    The agency received no comments or additional data to cause it to 
    change this tentative finding. Therefore, the agency now concludes 
    that, for the public to understand fully, in the context of other 
    dietary components, the relationship between consumption of sugar 
    alcohols and the promotion of dental caries, information about other 
    carbohydrates needs to be included as part of the claim.
        -In addition, the agency acknowledges the comments' emphasis on 
    issues related to frequency of consumption. The importance of this 
    factor is supported by the Dietary Guidelines for Americans (Ref. 101). 
    FDA addressed this aspect of the diet-disease relationship when it 
    included a statement concerning frequent between meal consumption in an 
    example of a model health claim.
        - Therefore, in response to the comments, FDA is adding 
    Sec. 101.80(c)(2)(i)(A), which provides that the claim must include the 
    information that frequent between-meal consumption of foods high in 
    sugars and starches can promote tooth decay. This information is 
    consistent with the information provided to consumers in the Dietary 
    Guidelines for Americans (Ref. 101), which states that frequent eating 
    of foods high in sugars and starches as between-meal snacks can promote 
    tooth decay. The agency is using the phrase ``sugars and starches,'' 
    which is used by the Dietary Guidelines for Americans (a document 
    intended for the general public), because it is apparently more 
    familiar to consumers, and thus likely to be better understood by them, 
    than is the phrase ``fermentable carbohydrates.''
        -Consistent with the proposal, the information that FDA is 
    requiring on packages with a total surface area available for labeling 
    of 15 or more square inches must include a statement that the sugar 
    alcohols present in the food do not promote tooth decay or (as 
    discussed in comment 17 of this document) may reduce the risk of tooth 
    decay (Sec. 101.80(c)(2)(i)(B)).
        -Further, to assist consumers in comprehending the information 
    specific to this claim within the context of the total daily diet, and 
    to avoid confusion about sugar alcohols' role in the diet given the 
    inclusion of information about starches, FDA is providing in 
    Sec. 101.80(d)(4) that the claim may state that the sugar alcohol 
    serves as a sweetener. This information will clarify that the sweetener 
    used in the product does not promote tooth decay.
        -Additionally, the agency recognized in preparing the final rule 
    that it had inadvertently failed to provide for the declaration of the 
    nutrient in proposed Sec. 101.80(c)(2)(i). Therefore, FDA is adding 
    Sec. 101.80(c)(2)(i)(C) which states that in specifying the nutrient, 
    the claim shall state ``sugar alcohol,'' ``sugar alcohols,'' or use the 
    name of the specific sugar alcohol. This approach is consistent with 
    the approach that the agency has taken in Sec. 101.9(c)(6)(iii) on the 
    declaration of sugar alcohols within the Nutrition Facts panel.
        -In light of these revisions, FDA has redesignated proposed 
    Sec. 101.80(c)(2)(i)(A) (see 60 FR 37507 at 37530) as 
    Sec. 101.80(c)(2)(i)(B) and redesignated proposed 
    Sec. 101.80(c)(2)(i)(B), in which the agency stated that the terms 
    ``dental caries'' or ``tooth decay'' be used to specify the disease, as 
    Sec. 101.80(c)(2)(i)(D). There were no comments on the latter 
    provision.
        -15. One comment agreed with the abbreviated claim and stated that 
    it carries the necessary consumer message. The comment further stated 
    that, as a result, package size should not determine the length of the 
    health claim. -
        -The agency disagrees. As discussed in the agency's response to 
    comment 14., issues related to providing information about dietary 
    factors are relevant to the requirement that the claim enable the 
    public to understand the significance of the information in the context 
    of a total daily diet (section 403(r)(3)(B)(iii) of the act). While the 
    claim for sugar alcohols is about the effect of using them to replace 
    dietary sugars, the agency is persuaded by other comments that the 
    claim should include information to set the message within the broader 
    context of fermentable carbohydrates and their frequency of consumption 
    so as to provide overall dietary information that is useful to 
    consumers. The importance of fermentable carbohydrates and of the 
    frequency of consuming such foods between meals is supported by the 
    Dietary Guidelines for Americans (Ref. 101).
        -16. One comment stated that the elements of the claim for small 
    packages do not adequately explain the significance to a person's diet 
    of including the particular food product bearing the claim.
        -As discussed in the proposed rule (see 60 FR 37507 at 37525), the 
    claim ``useful in not promoting tooth decay'' has been used on a 
    limited number of foods, primarily chewing gums and confectioneries, 
    for 20 years. This claim has a history of being used by consumers 
    without particular confusion. Thus, the agency concludes that it is not 
    necessary to include additional information as part of this claim when 
    it appears on small packages to prevent it from being misleading.
        -17. Some comments stated that it was important that label 
    statements of the claim include reference to nondietary factors, 
    particularly oral hygiene, that are associated with dental caries. One 
    comment stated that dental care and oral hygiene are more important 
    factors in the nonpromotion of dental caries than the substitution of 
    sugar alcohol-containing foods for sugar-containing foods.
        -One comment, however, stated that the requirement that a claim 
    state that tooth decay depends on many factors (for larger packages) 
    does not add to an understanding of the claim and would only confuse 
    the message that sugar alcohol-containing products do not promote tooth 
    decay. Other comments supported an abbreviated claim and asserted that 
    reference to the multifactorial etiology of dental caries does not add 
    information needed by consumers.
        -As discussed in the proposal, the agency acknowledges that the 
    development of dental caries involves a complex interplay of many 
    factors, both dietary and nondietary. Nonetheless, while there is an 
    important role for dental care and oral hygiene in reducing the 
    incidence of dental caries, the agency notes that current and well 
    recognized recommendations also stress the role of diet.
        -In response to comments described above, the agency has considered 
    the need for the inclusion of statements within the label claim 
    concerning the multifactorial nature of dental caries and information 
    on nondietary factors to help reduce the risk of this disease.
        -The agency notes that comments that requested that the agency 
    require that nondietary factors be included in the health claim 
    provided no evidence that claims about the relationship among sugar 
    alcohols, fermentable carbohydrates, and dental caries are
    
    [[Page 43441]]
    
    misleading if a reference to nondietary factors is not included in the 
    claim. Given the unique history of this claim, i.e., that it has been 
    used for approximately 20 years, and the fact that the incidence of 
    dental caries has decreased over that period, the agency is not 
    persuaded that the absence of reference to specific nondietary factors 
    in this claim has had adverse effects that would suggest that the claim 
    is misleading.
        -Moreover, FDA has decided not to require that the statement 
    ``depends on many factors'' be included as part of the claim on 
    products with 15 or more square inches of space available for labeling. 
    The fact that the incidence of dental caries has declined over the past 
    20 years strongly suggests that public health education, including 
    information in preventive dental measures, that has been available to 
    consumers during this period has been effective (Ref. 95). Moreover, as 
    stated above, FDA is aware of the unique history of this claim. Given 
    the history of this claim and the public education that has been 
    available, FDA has reconsidered its tentative view that the statement 
    ``depends on many factors'' is necessary to the consumer understanding 
    of the claim. FDA concludes that the available evidence demonstrates 
    that the claim is complete without this information, and, therefore, 
    that this information need not be made a required element of this 
    health claim. However, the agency is providing that the information may 
    be included in the health claims.
        -Thus, in this document, the agency is deleting proposed paragraphs 
    Sec. 101.80(c)(2)(i)(C) and (c)(2)(i)(D). It is modifying 
    Sec. 101.80(d)(2) to provide that the claim may state that the 
    development of dental caries depends on many factors and list those 
    risk factors. In place of proposed Sec. 101.80(c)(2)(i)(C), the agency 
    is requiring in Sec. 101.80(c)(2)(i)(F) that the claim not imply that 
    consumption of foods containing sugar alcohols is the only recognized 
    means of achieving reduced risk of dental caries. Consistent with these 
    changes, FDA has deleted the model claim in proposed Sec. 101.80(e)(2) 
    that illustrated a claim with the statement ``depends on many 
    factors.''
        -18. One comment suggested since the agency had proposed to 
    authorize a claim using the terminology ``does not promote,'' then a 
    claim relative to reducing the risk for dental caries was a separate 
    claim that would not be authorized by a final rule in this proceeding. 
    The comment suggested that it would be necessary to obtain separate 
    authorization for such a claim as a means of conveying the relative 
    superiority of certain sugar alcohols in affecting the occurrence of 
    dental caries.
        -The proposal on sugar alcohols focused on the nonpromotion of 
    dental caries, but it was not the agency's intent to specifically 
    exclude the concept of risk reduction from the claim. In response to 
    this comment, the agency considered the coverage of the claim and noted 
    that, in proposed Sec. 101.80(d)(3), it had listed risk factors for 
    dental caries. One factor listed was the frequent consumption of 
    sucrose or other fermentable carbohydrates. The substitution of sugar 
    alcohols in diets for foods containing sucrose or other fermentable 
    carbohydrates reduces exposure to one risk factor for dental caries. 
    Thus, FDA has concluded that it is appropriate to characterize the 
    relationship as ``may reduce the risk.'' To make this finding explicit, 
    the agency has inserted the phrase ``may reduce the risk'' in 
    Sec. 101.80(c)(2)(i)(B).
        -As for claims of superiority, the agency notes that the provision 
    of the act that authorizes health claims focuses on diet/disease 
    relationships. Once a relationship is established, there is no further 
    provision within the health claim regime for claims of superiority in 
    affecting the disease in question. A manufacturer who makes a statement 
    on the label or in labeling of a food concerning the superiority of the 
    effect of one substance compared to another does so at the risk that 
    FDA will find the claim to be false and misleading and thus subject to 
    regulatory action under section 403(a) of the act.
    
    G. Plaque pH Test
    
        -In Sec. 101.80(c)(2)(ii)(C), FDA proposed to provide that to 
    qualify to bear a claim, the sugar alcohol-containing food not lower 
    plaque pH below 5.7 by bacterial fermentation either during consumption 
    or up to 30 minutes after consumption, as measured by in vivo tests. 
    The agency asked for comments on this approach.
        -19. Two comments asked that FDA clarify that sugar alcohol-
    containing chewing gums and confectioneries will be exempt from any 
    plaque pH test requirement. One comment stated that the plaque pH 
    requirement should be specific to sugar alcohol-containing foods that 
    also contain fermentable carbohydrates. One comment stated that 
    manufacturers can tell from the composition of the food if the plaque 
    pH test is needed. One comment stated that the agency should give 
    manufacturers flexibility in selecting the best protocol for testing 
    plaque pH. One comment requested that the agency be more specific as to 
    the type of test used to determine plaque pH. The comment stated that 
    the pH of 5.7 is an appropriate threshold value for the pH when 
    measured at the inner plaque surface (i.e., at the interface between 
    plaque and dental enamel) at interproximal sites. The comment stated 
    that a different threshold pH value is appropriate for plaque pH 
    measurements obtained with other techniques and at other sites.
        -In the proposed rule, the agency also stated that the 
    acidogenicity of HSH and other sugar alcohol mixtures is related to the 
    manufacturing process, and that the process may vary among 
    manufacturers. The agency asked for comments on how to determine 
    whether sugar alcohol mixtures, such as HSH, when used in a food whose 
    label bears a dental caries health claim, are in compliance with any 
    final rule resulting from the proposal (60 FR 37507 at 37524). One 
    comment stated that the agency's concern regarding the potential 
    acidogenicity of HSH is covered with the plaque pH test.
        -When FDA asked for comments in the proposal about establishing a 
    minimum plaque pH requirement, it was addressing concerns that a sugar 
    alcohol-containing food might also contain a fermentable carbohydrate 
    that would render the food cariogenic (60 FR 37507 at 37526). The 
    application of the plaque pH test is thus predicated on the inclusion 
    of fermentable carbohydrates in a food that contains sugar alcohols. 
    Consequently, there is no need to exempt certain sugar alcohol-
    containing foods from the plaque pH test. Rather, if sugar alcohols are 
    used as sweeteners in a food, and there are no fermentable 
    carbohydrates in the food, testing is not necessary.
        -In response to the comment concerning the need for manufacturers 
    to have flexibility in selecting the method for measuring plaque pH, 
    the agency points out that it does not require manufacturers who wish 
    to make the health claim to perform the plaque pH test, nor does it 
    require that a specific procedure be used when the test is performed. 
    However, the agency is specifying in Sec. 101.80(c)(2)(ii)(C) the 
    method that it will use to determine whether a food complies with the 
    plaque pH requirement in this regulation. In doing so, FDA is 
    responding to the comment that requested that the agency specify the 
    procedure. Manufacturers are free to decide for themselves whether and 
    how to test their products to satisfy themselves that the foods comply 
    with Sec. 101.80(c)(2)(ii)(C)). If they fail to do so, they risk that 
    FDA will find in its compliance testing of their food that the food 
    does not comply with the plaque
    
    [[Page 43442]]
    
    pH standard and thus is subject to regulatory action.
        -The plaque pH test that the agency will use to determine whether a 
    food is in compliance with this final rule is the indwelling plaque pH 
    method, an intraoral telemetry method. The Swiss have used this method 
    since 1969 for regulatory purposes, and it has been shown to be very 
    reliable (Ref. 75). The indwelling plaque pH method is considered by 
    many as the benchmark for plaque pH testing (Ref. 46). It is not the 
    agency's intent to use this method of plaque pH testing as a means to 
    rank the relative cariogenicity of foods; rather, the agency will use 
    this method to determine whether foods that contain both sugar alcohols 
    and fermentable carbohydrates qualify to bear this health claim.
        -With regard to the agency's request for comments about the 
    potential acidogenicity of HSH and other sugar alcohol mixtures, the 
    agency agrees with the comment that stated that the agency's concern 
    regarding the potential acidogenicity of HSH is covered with the plaque 
    pH test. Manufacturers who produce HSH will be responsible to ensure 
    that their product, when used in a food that bears a dental caries 
    health claim, is in compliance with the Sec. 101.80. If sugar alcohol 
    mixtures, such as HSH, are used as sweeteners in a food, and there are 
    no fermentable carbohydrates contributed by the sugar alcohol mixture 
    or in the food, plaque pH testing is not necessary. If fermentable 
    carbohydrates are present, manufacturers will need to ensure that the 
    mixture does not lower plaque pH below 5.7.
    
    H. Applicability of Claim to Other Substances
    
        -In proposed Sec. 101.80(c)(2)(ii)(B), the agency specified the 
    substances (i.e., sugar alcohols) that are the subject of the sugar 
    alcohol and dental caries proposed regulation.
        -20. Two comments requested that proposed Sec. 101.80(c)(2)(ii)(B) 
    be modified to allow any sugar alcohol that may be developed in the 
    future to fall under this health claim without amending the regulation.
        -FDA is denying this request. Under the general requirements for 
    health claims, the petitioner must show how the substance that is the 
    subject of the health claim conforms to the requirements of 
    Sec. 101.14(b). For those substances that are to be consumed at other 
    than decreased dietary levels, the petitioner must demonstrate to FDA's 
    satisfaction that the substance is safe and lawful under the applicable 
    food safety provisions of the act (Sec. 101.14(b)(3)(ii)). Moreover, 
    the agency would expect, in the case of a new sugar alcohol, to see 
    evidence that the substance will not lower plaque pH below 5.7. If such 
    showing is made, FDA will take action to add the substance to the list 
    in this regulation, which has been renumbered as 
    Sec. 101.80(c)(2)(ii)(B).
        -21. Two comments requested that FDA make provision in this 
    regulation for additional FDA approved ingredients, e.g., polydextrose, 
    that satisfy the requirement that they do not lower plaque pH below 
    5.7. The comments stated that this would obviate the need to amend the 
    regulation as additional ingredients become available in the future. 
    One comment stated that the plaque pH test serves as the true marker of 
    noncariogenicity, not the presence of sugar alcohols or the absence of 
    sugars. The comment suggested that the plaque pH test is the only 
    critical endpoint necessary to justify use of this health claim.
        -One comment noted that the agency suggested that this claim will 
    apply primarily to snack foods that do not play a fundamental role in 
    structuring a healthy diet. The comment stated that other food products 
    could be designed to not lower plaque pH below the required level of 
    5.7. The comment stated that products widely known to be noncariogenic 
    and to have a role in a healthy diet, e.g., cheese, would be unable to 
    bear this claim. The comment suggested that the claim be limited to 
    chewing gums and confectioneries, although the comment provided no 
    background on how to differentiate confectioneries from snack foods, 
    nor did it provide evidence as to how this limitation would advance the 
    purposes of the health claim provisions of the act.
        -FDA is denying the requests to make provision in this final rule 
    for other ingredients, such as polydextrose, that do not lower plaque 
    pH below 5.7. The requirement that the food not lower plaque pH below 
    5.7 is not the only criterion that must be satisfied for a food to bear 
    the health claim. The agency recognizes that there may be scientific 
    evidence to show that foods that do not contain sugar alcohols would 
    qualify to bear a nonpromotion of dental caries health claim. However, 
    the health claim petition that is the subject of this rulemaking (Ref. 
    1), which was filed in accordance with the requirements of Sec. 101.70, 
    addressed only certain sugar alcohols and presented the scientific 
    evidence pertaining to those substances. The agency did not review the 
    totality of publicly available evidence on the cariogenicity of other 
    ingredients or other foods. Without assurances that the substance in 
    question, e.g., polydextrose, meets the entire set of criteria for a 
    health claim, the authorization for the claim cannot be broadened to 
    include other substances.
        -In response to the comment as to why the claim is being allowed on 
    foods that contain sugar alcohols (and meet other criteria) and is not 
    limited to only gums and confectioneries, the agency points out that 
    the claim is based upon the substitution of sugar alcohols for 
    fermentable carbohydrates, not on the use of certain foods. To the 
    extent that consumers can select foods that contain fewer fermentable 
    carbohydrates, their chances of reducing their risk of developing 
    dental caries are increased. Limiting the claim to certain categories 
    of foods would limit the significance of the claim and not serve the 
    interests of the consumer.
    
    I. Other Issues
    
        -The agency proposed that any final rule that may issue based upon 
    the proposal become effective 30 days following its publication.
        -22. Two comments requested that FDA change the effective date of 
    the final rule to 6 months following its publication. The comments 
    stated that this change would allow time for industry to change labels 
    on products that may need changing if wording changes on the claim are 
    needed.
        -FDA has considered the issue of the compliance date and has 
    concluded that the compliance date for this regulation will be January 
    1, 1998. This date is consistent with that proposed by FDA in the 
    ``Uniform Compliance Date for Food Labeling Regulations'' proposal rule 
    (hereinafter referred to as the ``uniform compliance date'' proposed 
    rule) (61 FR 16422, April 15, 1996). In that document, the agency 
    stated that it periodically has announced uniform compliance dates for 
    new food labeling requirements. It stated that use of a uniform 
    compliance date provides for an orderly and economical industry 
    adjustment to new labeling requirements by allowing sufficient lead 
    time to plan for the use of existing label inventories and the 
    development of new labeling materials. FDA stated that this policy also 
    serves consumers' interests because the increased cost of multiple 
    short-term label revisions that would otherwise occur would likely be 
    passed on to consumers in the form of higher food prices. Although FDA 
    is adopting January 1, 1998, as the compliance date, the agency is 
    encouraging firms to begin voluntary compliance as early as possible 
    after publication of this rule and to begin making changes when they 
    reprint their labels.
    
    [[Page 43443]]
    
    -III. Decision to Authorize a Health Claim Relating Sugar Alcohols 
    to Dental Caries
    
        -FDA has considered all of the comments that it received in 
    response to the sugar alcohol and dental caries health claim proposal. 
    The agency concludes that the relationship between sugar alcohols and 
    dental caries is truthful, not misleading, and scientifically valid in 
    that there is significant scientific agreement based on the totality of 
    publicly available scientific evidence that sugar alcohols do not 
    promote dental caries. Therefore, FDA is authorizing this claim, 
    although based on some of the comments, the agency has been persuaded 
    to make a number of editorial changes in the proposed codified material 
    of the health claim.
    
    -IV. Environmental Impact
    
        -The agency has previously considered the environmental effects of 
    this rule as announced in the proposed rule (60 FR 37507). At that 
    time, the agency determined under 21 CFR 25.24(a)(11) that this action 
    is of a type that does not individually or cumulatively have a 
    significant effect on the human environment. No new information or 
    comments have been received that would affect the agency's previous 
    determination that there is no significant impact on the human 
    environment and that an environmental impact statement is not required.
    
    -V. Analysis of Impacts
    
        -FDA has examined the economic implications of the final rule 
    establishing a health claim for sugar alcohols and dental caries as 
    required by Executive Order 12866 and the Regulatory Flexibility Act 
    (Pub. Law 96-354) as amended by the Small Business Regulatory 
    Enforcement Fairness Act of 1996. Executive Order 12866 directs 
    agencies to assess all costs and benefits of available regulatory 
    alternatives and, when regulation is necessary, to select regulatory 
    approaches that maximize net benefits (including potential economic, 
    environmental, public health and safety effects; distributive impacts; 
    and equity). FDA finds that this final rule is not a significant rule 
    as defined by Executive Order 12866.
        -In response to the proposal, FDA received two comments suggesting 
    that the costs of the proposed health claim exceed the benefits. One 
    comment suggested that parents who substitute sugar alcohol containing 
    snacks for other snack foods will be trading dental caries for gastric 
    problems in their young children. The second comment stated that, 
    because gums and candies that contain sugar alcohols are more expensive 
    than other sweets, some consumers may purchase them with funds that 
    otherwise would be used for preventive dental health measures.
        -The agency is unconvinced by these comments. Because the claim is 
    already being used on many products in ways that would satisfy the 
    conditions for use as approved by this regulation, the agency does not 
    agree that the claim will cause consumers to switch from sugar-
    containing products to existing products containing sugar alcohols. 
    Therefore, it is unlikely that this regulation will result in any 
    significant changes in consumer behavior. In fact, any change in 
    consumer behavior because of sugar alcohols most likely has already 
    taken place. This regulation is thus not expected to cause an increase 
    in gastric problems.
        -The agency also does not agree that this regulation is likely to 
    result in a decrease in preventive dental health measures. Consumers of 
    sugar alcohol containing foods purchase the products either because of 
    their dietetic attributes or because of their role in preventive dental 
    health. The majority of sugar alcohol containing foods that would 
    qualify for the health claim currently have sugar-free claims which are 
    required to be accompanied by a statement that the product is not a 
    low-calorie food. Therefore, it is unlikely that these products are 
    being consumed by calorie-conscious individuals.
        -The health claim should have no impact on the purchases of 
    consumers who consume these products for the dietetic properties 
    because neither sugary foods nor preventive dental health measures are 
    substitutes for dietetic foods. The agency is aware of no evidence that 
    sugar alcohol containing foods and preventive dental health measures 
    are substitutes for dentally concerned consumers. In fact, it is more 
    likely that these consumers view the two categories as complementary 
    products working together as a part of a dental health regime. It is 
    likely that the cross elasticity of demand, a numerical measure of the 
    connection between two goods, for sugar alcohol containing foods and 
    preventive dental health measures is either not significantly different 
    from zero, or negative. In other words, the two product categories are 
    either not close substitutes or are complementary products. Therefore, 
    the agency rejects the assertion that the use of preventive dental 
    health measures will decline as a result of this rule.
        -Although the benefits of this rule are minimal, the costs of this 
    regulation are also anticipated to be small. FDA is aware that some 
    firms are already using similar claims on product labels. It is likely 
    that most of these claims satisfy the criteria described in this 
    rulemaking. However, because FDA is requiring er claims for larger 
    package sizes, some product labels may need to be revised. To the 
    extent that labels need revision, this final rule will impose costs. On 
    average, the administrative, redesign, and inventory disposal costs of 
    revising a label for the affected product categories within a six month 
    compliance period are between $800 and $1525 per label depending on the 
    location of the claim. Because FDA does not know the number of sugar 
    alcohol claims currently being made nor the proportion of existing 
    claims that do not meet FDA's criteria, the agency cannot estimate the 
    total costs of this regulation.
        -The Regulatory Flexibility Act as amended requires analyzing 
    options for regulatory relief for small businesses. According to the 
    information currently available to the agency, of the relatively small 
    number of products that would require relabeling as a result of this 
    final rule, none are produced by small firms. Therefore, the agency 
    certifies that this rule will not have a significant impact on a 
    substantial number of small businesses.
    
    -VI. Paperwork Reduction Act
    
        -This final rule contains no information collection or 
    recordkeeping requirements under the Paperwork Reduction Act of 1995 
    (44 U.S.C. 3501 et seq.).

         Therefore, under the Federal Food, Drug, and Cosmetic Act and 
    under authority delegated to the Commissioner of Food and Drugs, 21 CFR 
    part 101 is amended as follows:
    
    [[Page 43446]]
    
    PART 101--FOOD LABELING
    
         1. The authority citation for 21 CFR part 101 is revised to read 
    as follows:
    
         Authority: Secs. 4, 5, 6 of the Fair Packaging and Labeling Act 
    (15 U.S.C. 1453, 1454, 1455); secs. 201, 301, 402, 403, 409, 701 of 
    the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 321, 331, 342, 
    343, 348, 371).
    
         2. New Sec. 101.80 is added to subpart E to read as follows:
    
    Sec. 101.80   Health claims: dietary sugar alcohols and dental caries.
    
         (a) Relationship between dietary carbohydrates and dental caries. 
    (1) Dental caries, or tooth decay, is a disease caused by many factors. 
    Both environmental and genetic factors can affect the development of 
    dental caries. Risk factors include tooth enamel crystal structure and 
    mineral content, plaque quantity and quality, saliva quantity and 
    quality, individual immune response, types and physical characteristics 
    of foods consumed, eating behaviors, presence of acid producing oral 
    bacteria, and cultural influences.
        -(2) The relationship between consumption of fermentable 
    carbohydrates, i.e., dietary sugars and starches, and tooth decay is 
    well established. Sucrose, also known as sugar, is one of the most, but 
    not the only, cariogenic sugars in the diet. Bacteria found in the 
    mouth are able to metabolize most dietary carbohydrates, producing acid 
    and forming dental plaque. The more frequent and longer the exposure of 
    teeth to dietary sugars and starches, the greater the risk for tooth 
    decay.
        -(3) Dental caries continues to affect a large proportion of 
    Americans. Although there has been a decline in the prevalence of 
    dental caries among children in the United States, the disease remains 
    widespread throughout the population, imposing a substantial burden on 
    Americans. Recent Federal government dietary guidelines recommend that 
    Americans choose diets that are moderate in sugars and avoid excessive 
    snacking. Frequent between-meal snacks that are high in sugars and 
    starches may be more harmful to teeth than eating such foods at meals 
    and then brushing.-
         (4) Sugar alcohols can be used as sweeteners to replace dietary 
    sugars, such as sucrose and corn sweeteners, in foods such as chewing 
    gums and certain confectioneries. Dietary sugar alcohols are 
    significantly less cariogenic than dietary sugars and other fermentable 
    carbohydrates.
         (b) Significance of the relationship between sugar alcohols and 
    dental caries. Sugar alcohols do not promote dental caries. Sugar 
    alcohols are slowly metabolized by bacteria to form some acid. The rate 
    and amount of acid production is significantly less than that from 
    sucrose and other fermentable carbohydrates and does not cause the loss 
    of important minerals from tooth enamel.
         (c) Requirements. (1) All requirements set forth in Sec. 101.14 
    shall be met, except that sugar alcohol-containing foods are exempt 
    from section Sec. 101.14(e)(6).
         (2) Specific requirements. (i) Nature of the claim. A health claim 
    relating sugar alcohols, compared to other carbohydrates, and the 
    nonpromotion of dental caries may be made on the label or labeling of a 
    food described in (c)(2)(ii) of this section, provided that:
        -(A) The claim shall state that frequent between-meal consumption 
    of foods high in sugars and starches can promote tooth decay.
        -(B) The claim shall state that the sugar alcohol present in the 
    food ``does not promote,'' ``may reduce the risk of,'' ``useful [or is 
    useful] in not promoting,'' or ``expressly [or is expressly] for not 
    promoting'' dental caries;
        -(C) In specifying the nutrient, the claim shall state ``sugar 
    alcohol,'' ``sugar alcohols,'' or the name or names of the sugar 
    alcohols, e.g., ``sorbitol.''
        -(D) In specifying the disease, the claim uses the following terms: 
    ``dental caries'' or ``tooth decay.''
         (E) The claim shall not attribute any degree of the reduction in 
    risk of dental caries to the use of the sugar alcohol-containing food.
        -(F) The claim shall not imply that consuming sugar alcohol-
    containing foods is the only recognized means of achieving a reduced 
    risk of dental caries.
        -(G) Packages with less than 15 square inches of surface area 
    available for labeling are exempt from paragraphs (A) and (C) of this 
    section.
         (ii) Nature of the food. (A) The food shall meet the requirement 
    in Sec. 101.60(c)(1)(i) with respect to sugars content.
         (B) The sugar alcohol in the food shall be xylitol, sorbitol, 
    mannitol, maltitol, isomalt, lactitol, hydrogenated starch 
    hydrolysates, hydrogenated glucose syrups, or a combination of these.
         (C) When fermentable carbohydrates are present in the sugar 
    alcohol-containing food, the food shall not lower plaque pH below 5.7 
    by bacterial fermentation either during consumption or up to 30 minutes 
    after consumption, as measured by the indwelling plaque pH test found 
    in ``Identification of Low Caries Risk Dietary Components,'' T. N. 
    Imfeld, Volume 11, Monographs in Oral Science, 1983, which is 
    incorporated by reference in accordance with 5 U.S.C. 552(a) and 1 CFR 
    part 51. Copies may be obtained from Karger AG Publishing Co., P. O. 
    Box, Ch-4009 Basel, Switzerland, or may be examined at the Center for 
    Food Safey and Applied Nutrition's Library, 200 C St. SW., rm. 3321, 
    Washington, DC, or at the Office of the Federal Register, 800 North 
    Capitol St. NW., suite 700, Washington, DC.
         (d) Optional information. (1) The claim may include information 
    from paragraphs (a) and (b) of this section, which describe the 
    relationship between diets containing sugar alcohols and dental caries.
         (2) The claim may indicate that development of dental caries 
    depends on many factors and may identify one or more of the following 
    risk factors for dental caries: Frequent consumption of fermentable 
    carbohydrates, such as dietary sugars and starches; presence of oral 
    bacteria capable of fermenting carbohydrates; length of time 
    fermentable carbohydrates are in contact with the teeth; lack of 
    exposure to fluoride; individual susceptibility; socioeconomic and 
    cultural factors; and characteristics of tooth enamel, saliva, and 
    plaque.
    
    [[Page 43447]]
    
        -(3) The claim may indicate that oral hygiene and proper dental 
    care may help to reduce the risk of dental disease.
        -(4) The claim may indicate that the sugar alcohol serves as a 
    sweetener.
         (e) Model health claim. The following model health claims may be 
    used in food labeling to describe the relationship between sugar 
    alcohol-containing foods and dental caries.
        -(1) Example of the full claim:
        -(i) Frequent eating of foods high in sugars and starches as 
    between-meal snacks can promote tooth decay. The sugar alcohol [name, 
    optional] used to sweeten this food may reduce the risk of dental 
    caries.
        -(ii) Frequent between-meal consumption of foods high in sugars and 
    starches promotes tooth decay. The sugar alcohols in [name of food] do 
    not promote tooth decay.-
        -(2) Example of the shortened claim for small packages:
        -(i) Does not promote tooth decay.
        -(ii) May reduce the risk of tooth decay.
