At no point in US history have food products displayed so many symbols and statements proclaiming nutrition and health benefits. Front-of-package claims, often used in violation of Food and Drug Administration (FDA) labeling regulations, have become ubiquitous in food marketing.1,2 Recently, the FDA embarked on an initiative to review front-of-package labeling and asked the Institute of Medicine to consider eventual recommendation of a single, standardized guidance system. Front-of-package labels may so thoroughly mislead the public that another option deserves consideration—eliminate all nutrition and health claims from the front of processed food packages while strengthening the Nutrition Facts Panel.

A Century of Regulatory Conflict

In 1906, the Pure Food and Drug Act prohibited food labels from bearing statements that were “false or misleading in any particular,” a proscription interpreted to mean that labels could not display health claims. Food manufacturers successfully challenged this interpretation in court. In 1912, Congress passed the Sherley Amendment authorizing actions against health claims that were false and fraudulent. For decades, the FDA interpreted any statement of health benefit as meeting both criteria.

Companies could, however, list nutrient contents. Manufacturers understood the marketing potential of this exemption and began fortifying foods with vitamins almost as soon as they were discovered. The FDA attempted to limit fortification to nutrients important for public health, but companies pressed for the right to use more.

In 1969, President Nixon convened the White House Conference on Food, Nutrition, and Health to explore ways to end hunger and malnutrition. A food industry task force recommended nutrient fortification, not only of wheat, corn, and rice, but also of snack foods and chocolate.3 To address public health goals, the FDA permitted food packages to indicate “contains 7 essential nutrients,” but continued to prohibit statements that food products could prevent, treat, or mitigate disease. These, the agency insisted, constituted drug claims requiring scientific substantiation.

In 1984, Kellogg arranged with the National Cancer Institute to endorse a health claim for All-Bran cereal. Within 6 months, All-Bran's market share increased by 47%, sending an unmistakable message that health claims sell products.4 Subsequently, Kellogg filed a “citizens' petition” with the FDA arguing a legal basis for health claims.5 Congress incorporated the petition's suggestions when it passed the Nutrition Labeling and Education Act of 1990 instructing the FDA to authorize scientifically substantiated health claims on foods.

In 1994, Congress passed the Dietary Supplement Health and Education Act, which permitted supplement labels to claim support for some structure or function of the body. Food companies demanded similar claims. The FDA Modernization Act of 1997 and lawsuits during the Bush administration weakened the FDA's power to stop them. Three types of claims—nutrient-content, health, and structure/function—proliferated on food products.2

Another type of food labeling, endorsements of nutritional quality, began to appear in 1995, with the American Heart Association's symbol indicating heart-healthy products low in total fat, saturated fat, sodium, and cholesterol. More recently, PepsiCo, Kraft, and other companies developed self-endorsement labeling systems, and General Mills introduced nutrition-at-a-glance symbols. Such symbols are now so plentiful that Consumers Union sponsors a Web site to track and evaluate them.6

Misleading Nature of Current Practices

The bewildering array of claims for increasingly remote health benefits has recently elicited concern. The Smart Choices program, a voluntary initiative involving several food companies, was the focus of an exposé by the New York Times and was threatened with legal action by the Connecticut attorney general.7 The program is now suspended. The San Francisco city attorney forced Kellogg to remove a claim that sweetened breakfast cereals “help support your child's immunity.”

The FDA now intends to examine the entire issue of front-of-package labeling, insisting that the systems used “be nutritionally sound, well-designed to help consumers make informed and healthy food choices, and not false or misleading.” The FDA also argues that “point of purchase labeling, including front-of-package labeling or corresponding shelf labeling . . . can be an effective way of promoting informed food choices and helping consumers construct healthier diets.”8

For a century, food manufacturers have lobbied for the right to use health claims in marketing, justifying their demands on precisely these grounds. Health claims demonstrably promote sales. But do they promote health? Research suggests that consumers believe front-of-package claims, perceive them to be government-endorsed, and use them to ignore the Nutrition Facts Panel.9,10 Indeed, current practices may mislead the public in several ways:

(1) Few, if any, claims can be verified. To be marketed, drugs must be proved safe and effective through randomized controlled trials. Although specific dietary components may be linked to improved health outcomes, food products containing that dietary component might not have the same effect. A diet of whole and minimally processed foods provides more than 40 essential nutrients and countless phytochemicals that interact in complex ways to promote health. The claim, for example, that a refined breakfast cereal could boost a child's immune system due to the presence of few antioxidants is tenuous at best. No independent agency would likely invest funds in high-quality clinical trials to test such possibilities.

(2) Claims based on individual nutritional factors are misleading. Whereas drug adverse effects must be disclosed in advertisements, front-of-package health claims have a selective focus, ignoring the presence of potentially unhealthful aspects (eg, the sugar or salt content in a prepared breakfast cereal).

(3) Even front-of-package labels restricted to nutrient content can be deceptive by presenting information out of context. Although an 8-oz serving of a sugared beverage has fewer calories than a 1-oz serving of nuts, a dietary choice based on this difference would be misguided.

(4) “Healthier” processed foods are not necessarily healthy. Manufacturers can manipulate snack food ingredients by replacing fat or sugar with refined starch, yielding a higher rating score with little meaningful improvement in nutritional quality. Moreover, health claims confer an aura of healthfulness that might encourage consumption of products of poor nutritional quality.

(5) Front-of-package claims produce conflicts of interest. Unless the FDA specifically dictates allowable claims for each food product (a logistically unfeasible approach), food companies' interest in selling more products will undermine the educational purpose of labeling.

Recommendations

If health claims are allowed on food packages, they should be regulated more strictly according to rigorous, evidence-based national standards. Because such standards are inevitably arbitrary and subject to manipulation, consideration should be given to an outright ban on all front-of-package claims. Doing so would aid educational efforts to encourage the public to eat whole or minimally processed foods and to read the ingredient lists on processed foods. In addition, the Nutritional Facts Panel should be revised and updated to facilitate informed dietary choice and minimize the possibility of marketing manipulation. Presently, consumers may greatly underestimate the calories in a 20-oz bottle of sugared beverage, for example, because the Nutrition Facts pertain to a serving size of 8 oz.

One remaining issue is the First Amendment. In its 1985 petition, Kellogg argued that First Amendment guarantees of commercial free speech establish companies' rights to make health claims.5 Although the courts seem to have interpreted the Amendment in this manner, the issue warrants reconsideration in light of current marketing practices. Claims that sugar-sweetened products make children smarter or boost their immunity are reason enough for the FDA to take this issue back to court and for Congress to consider legislative remedies.
