The FDA Should Allow Food Labeling Claims about Nutrient Content and Health

Executive Summary

Recent court cases finding that the Food and Drug Administration's bans on certain health claims are unconstitutional have prompted the agency to solicit comments about new approaches to food labeling. We recommend that FDA allow all nutrient content claims and all health claims, unless it can show them to be false and misleading. In particular, FDA should approve in advance any statements that quote or paraphrase authoritative peer-reviewed scientific studies. These changes are likely to substantially improve a consumer’s ability to choose food based on information about its nutritional content and its likely effects on health.


Recent court decisions striking down the Food and Drug Administration’s restrictions on constitutionally protected commercial speech have forced the FDA to reconsider its food labeling regulations. The way that FDA solicits comments about how to revise its programs to conform to these decisions demonstrates their profound implications. FDA asks,

"Do FDA’s speech related regulations advance the public health concerns they are designed to address?"[1] "Are there any regulations, guidance, policies and practices FDA should change, in light of governing First Amendment authority?"[2]

The recent Pearson v. Thompson decision by U.S. District Court for the District of Columbia implies that FDA may not constitutionally prohibit a health claim merely because the FDA believes the supporting scientific literature is inconclusive.[3] This decision complements the Supreme Court ruling in Thompson vs. Western Medical Center:[4] even when a restriction on commercial speech directly advances an important government interest, the government can and should advance it’s interest by adopting restrictions less burdensome than a ban. Together, these decisions require that FDA make a sharp departure from its current food labeling policy.

In light of these decisions, we make two general recommendations to the FDA about how to reform food labeling regulations so as to better provide consumers the nutritional information they need to purchase health-promoting foods: (1) To promote the dissemination of information about nutrients newly found to be important, we recommend that FDA allow all nutrient content claims that cannot be shown to be false or misleading. (2) In addition, we recommend that FDA allow any diet-disease claim about the health benefits of a particular food if the claim relies upon a reasonable basis, such as peer reviewed scientific research, and there exists no evidence that it is false or misleading.

We elaborate on the advantages of these recommendations below. To support our views we consider how FDA regulates labeling of two types of fat linked to heart disease: a "good" fat (omega three (n-3) polyunsaturated fatty acids) and a "bad" fat (trans fatty acids).

Our recommendations follow from a key empirical fact. Increased consumer awareness of key diet-health links, increased production of foods that promote health, and increased consumption of such foods, all followed the relaxation of food labeling regulations in the mid-1980s.[5] Several observations on the value of useful information about nutrient content and the incentives to supply it, also support these recommendations.

First, more information about nutritional content and links between nutrition and health would benefit consumers. Chronic disease, especially coronary heart disease (CHD), is a major cause of death for Americans; some estimates suggest that a significant portion of deaths from chronic disease could be averted through better nutrition.[6] Information about the nutritional content of specific foods as well as nutrition-disease links is essential if these health gains are to be realized. Moreover, nutrition information must be understood not only in the abstract by government officials and scientists, but by individual shoppers who choose foods with limited time and money.

Second, information about nutrition-disease links is dynamic--a result of constant changes in scientific understanding--so a satisfactory regulatory process must deliver new information quickly. The fundamental policy challenge is thus to encourage food suppliers to better inform consumers about the nutritional properties of foods and diet-disease links. We elaborate below on how FDA’s current regulatory program has failed to keep consumers informed about new research on the nutritional effects of different forms of fat.

Third, given the dynamic nature of information about nutrition-disease links, the supply of information is likely to respond to incentives. The quality and quantity of new research about the effects of diet on health may increase as the value and importance of such information increases. While nutritional information is intrinsically not patentable, and therefore unlikely to develop the proprietary aspects of information about new pharmaceutical products, we believe the importance of incentives in directing new nutrition research has not been adequately appreciated. Labeling regulations that facilitate nutrient content and health claims are likely to spur additional research into such effects, and such research may itself have significant social benefits.

Fourth, research indicates that consumers distinguish the quality of information by the credibility of its source.[7] There may be substantial advantages to greater competition in food quality as described on labels, as consumers are likely to treat manufacturers’ simple assertions more skeptically than conclusions of scientific researchers in peer-reviewed journals or endorsements by third parties committed to better foods.

Perhaps the most compelling rationale to reform FDA food regulation is that it has badly served consumers’ right to know what they are eating. If reputable scientific journals publish studies finding links between particular nutrients and disease, government has a deep and fundamental responsibility to allow retailers and manufacturers to list this information, and not to suppress it for years.

FDA currently prohibits many nutrient content claims (sometimes called descriptors) and health claims. In addition FDA prohibits factually correct content claims about nutrients not listed on its Nutrition Facts panel. For example, manufacturers cannot state on food labels that foods are free from or low in trans fat, or high in n-3 polyunsaturated fatty acids, because FDA has not defined these terms[8] In addition, FDA bans any health claim unless it finds in advance that it is supported by "significant scientific agreement."[9] We believe that FDA’s restrictive regulation of health claims and nutrient descriptors should be substantially relaxed in light of the new Court decisions.

Recommendation 1: The FDA should accept all nutrient content claims not found to be false or misleading using an evidence-based rule of reason.

FDA currently allows relative nutrient content claims only for nutrients for which daily values exist.[10] For example, it prohibits "low in trans fatty acids," or "higher in omega 3 fatty acids than brand x."[11] These restrictions are problematic because daily values for trans fatty acids and n-3 fatty acids do not now exist, even though the peer-reviewed scientific literature shows a large and growing consensus supporting adverse health effects of trans fats and beneficial effects of n-3 fatty acids.[12] Indeed, regarding trans fats, the National Research Council recently concluded "any incremental increase in intake increases CHD risk."[13] It refrained, however, from issuing a daily value.[14]

While FDA does allow food manufacturers to make statements regarding the absolute levels of nutrients not listed on the Nutrition Facts Panel, such as trans and omega 3 fatty acids,[15] disclosure of relative levels is key because it may help justify the cost of a voluntary labeling change or marketing campaign based on the diet-disease links.

FDA’s current approach keeps consumers in the dark. Consumers have not learned about the health effects of trans fatty acids in their food,[16] even though concerns about trans fatty acids have been in the scientific literature for nearly 10 years.[17] Food labels do not indicate n-3 levels, though the literature has suggested health benefits.[18] Moreover, delays in customer awareness will persist because the National Research Council in its most recent report has not established daily values for either trans fats or for n-3 fatty acids,[19] and FDA may take years to issue a final rule after NRC issues daily values.

The premise of the current approach, that disclosing relative nutrient levels is impossible without official daily nutrient values, is fundamentally flawed. It postpones references to diet-disease links on food labels until many years after credible evidence of diet-disease links first appears in authoritative scientific journals.

We recommend that FDA identify immediately a collection of truthful and non-misleading relative nutrient content claims that would be safe from FDA enforcement action. For example, FDA should approve in advance any comparative claim that brand x of food category x is lower in trans fatty acids than brand y or food category y, provided that the levels of trans fatty acids in the two brands or categories are identified. Similarly, claims that food A is higher in n-3 than food B should also be allowed, provided that the levels in the two foods are specified. Such simple policy changes would sidestep the delay of defining terms and convey substantial new and valid information about the nutritional content of foods to consumers.

Recommendation 2: Health claims should be permitted unless found to be false or misleading using an evidence-based rule of reason.

The FDA currently imposes a very stringent standard for health claims, requiring, in accordance with the Federal Food Drug and Cosmetic Act, that they be supported by "significant scientific agreement."[20] Many potential—and still banned—health claims are supported by scientific evidence that is persuasive, but not yet, in FDA’s judgement, supported by significant scientific agreement. "Significant scientific agreement" tends to require directed reports by the NRC as well as a lengthy rulemaking process specific to each nutrient. As analysts have known for years, policies on health claims that inadvertently prohibit genuinely true claims can misinform consumers about the health consequences of their decisions and have adverse effects on public health.[21] By relaxing its current, restrictive approach, FDA is likely to significantly improve consumers’ knowledge of foods likely to affect risks of chronic disease.

To clarify permissible health claims, the FDA should specify claims that are "safe harbors." In particular, the FDA should allow labels to reproduce any and all statements by the National Research Council that connect diet to risk of chronic illness. Furthermore, the FDA should allow direct quotes from all articles published in peer-reviewed journals, provided that such quotes are in context. Finally, the FDA should encourage parties independent of food manufacturers, such as the American Heart Association, to offer stamps of approval to foods that it believes promote healthy hearts.

This recommendation will result in a much more expansive set of health claims than is now permitted and will better inform consumers about the consequences of their food purchasing decisions. First, competition among food manufacturers will induce them to make distinctions among different types of health claims. Consumers will give the greatest weight to claims by the National Research Council, endorsements by the American Heart Association, or the FDA. Claims that appear in the academic literature without endorsement by expert panels will receive less attention. Claims made on the basis of poorly designed studies that have not passed peer review will be relatively unattractive to manufacturers because they are easily discredited and have little more credibility than simple assertions.

Moreover, relaxing the restrictions on health claims will greatly increase consumer information. A recent survey of consumer knowledge about the relationship between nutrition and health found a greater ignorance about trans fatty acids, for which FDA bans all health (and comparative nutrient content) claims, than saturated fats, for which FDA has allowed limited health and nutrient content claims.[22] This suggests that consumer information increases when restrictions on labeling are reduced.

This policy will encourage more truthful and non-misleading claims. For example, FDA’s "model" claim for saturated fats is "While many factors affect heart disease, diets low in saturated fat and cholesterol may reduce the risk of this disease."[23] FDA requires the statement to refer to both saturated fat and cholesterol, even though the NRC concludes simply "any incremental increase in [saturated fat] intake increases CHD risk."[24] It is striking that FDA policy to date has essentially banned such quotes from food labels, even though their greatest value lies with consumers who need to make more informed choices to significantly reduce their CHD risk.

The FDA also bans health claims about trans fatty acids, although it has been trying to reform this policy.[25] The NRC reports that trans fats are not essential and provide no known benefit to human health.[26] It also states that any increase in trans fatty acid intake increases CHD risk.[27] Further, NRC recommends that intake of trans fatty acids be as low as possible while consuming a nutritionally adequate diet.[28] Ironically, FDA’s policy on health claims involving trans fatty acids is more restrictive than its policy involving saturated fats, even though the NRC review suggests that trans fatty acids are more effective at raising cholesterol levels than saturated fats.[29] These NRC conclusions and similar statements should be promptly made available to American shoppers by allowing them to be included on food labels.

In the case of n-3 fatty acids from fish, health claims that successfully affect consumer behavior could provide substantial improvements in health, according to a growing body of scientific research. Hu et al. report that the relative risk of fatal CHD among women without previous diagnoses of CHD or cancer falls by nearly half as n-3 intake rises.[30] Marchioli et al. of the GISSI-Prevenzione Investigators, in a study of survivors of myocardial infarction, found that a randomly assigned n-3 dose of one gram per day reduced the risk of sudden death from CHD by half within 4 to 8 months.[31] Albert et al. found that n-3 fatty acids in fish are strongly associated with a reduced risk of sudden death among men without prior evidence of cardio-vascular disease, based on an analysis of healthy men over 17 years.[32] These studies confirm earlier research[33] that n-3 intake lowers the risk of CHD for men and women of varying health.

Intake of n-3 fatty acids also appears to protect against a variety of health conditions unrelated to heart disease. These include inflammatory diseases such as rheumatoid arthritis and asthma,[34] epileptic seizure,[35] endometrial cancer,[36] age-related macular degeneration,[37] prostate cancer,[38] and premature birth.[39]

Irrespective of one’s views about the health effects of increased n-3 intake, allowing voluntary disclosure of n-3 contents would provide consumers who believe that such benefits may exist--a entirely plausible position given the existing studies--an opportunity to choose their diet accordingly.

In conclusion, FDA’s efforts to reform its regulations to allow constitutionally protected commercial speech could substantially improve the public’s knowledge of both the nutrients in foods and the links between diet and health, provided that the agency permits a broad range of claims on labels that are truthful and not misleading.
