Deciphering Health Claims on Food Packaging
Food labels can be a confusing mix of numbers, percentages, and marketing phrases. Among the most prominent are health claims, statements suggesting a relationship between a food and a health-related condition. These claims are not all created equal and are subject to varying levels of scientific scrutiny and regulation depending on the country. For example, in the United States, the Food and Drug Administration (FDA) is the primary regulatory body, while the European Food Safety Authority (EFSA) oversees regulations in the EU.
Types of Health Claims Explained
Regulatory bodies, such as the FDA, classify health claims into different categories based on the strength of the scientific evidence supporting them.
-
Authorized Health Claims: These claims are backed by the highest level of scientific evidence and significant scientific agreement (SSA) among qualified experts. The FDA, in the U.S., must review and approve these claims through a formal petition process before they can be used. There is strong, conclusive evidence of the substance's effect. An example is the claim that a diet low in total fat and cholesterol and rich in whole grain foods may reduce the risk of heart disease.
-
Qualified Health Claims: These claims are based on scientific evidence, but the standard of proof is lower than for authorized claims. They must be accompanied by a qualifying statement that explains the uncertainty of the science. The FDA allows these claims based on enforcement discretion. An example might state, “Scientific evidence suggests, but does not prove, that [substance] may reduce the risk of [disease]”.
-
Structure/Function Claims: These claims describe the role of a nutrient or dietary ingredient in affecting the normal structure or function of the human body. Unlike health claims, they do not require FDA pre-approval, but the manufacturer must have scientific evidence to substantiate the claim. For dietary supplements, a specific disclaimer must be included, stating that the FDA has not evaluated the statement and the product is not intended to diagnose, treat, cure, or prevent any disease. Examples include “Calcium builds strong bones” or “Fiber promotes regularity”.
The Crucial Difference: Health vs. Nutrient Content Claims
It's important to distinguish health claims from nutrient content claims, which are also found on food packaging. While health claims link a food substance to a disease or health-related condition, nutrient content claims describe the level of a specific nutrient in a food.
-
Nutrient Content Claim Example: “Low-fat” or “high-fiber”. The regulations for these claims set specific criteria that must be met. For example, to be labeled “low-fat,” a food product must contain 3 grams of fat or less per serving.
-
Health Claim Example: “Diets low in saturated fat and cholesterol that include soluble fiber from whole grain oats may reduce the risk of heart disease”. This links the fiber to a specific health outcome.
A Comparative Look at Claim Types
| Feature | Authorized Health Claims | Qualified Health Claims | Structure/Function Claims |
|---|---|---|---|
| Scientific Evidence | Significant Scientific Agreement (SSA) among experts. | Supportive but less robust than SSA. | Reasonable evidence to support the claim. |
| FDA Approval | Requires pre-approval via a petition process. | Requires FDA to issue a letter of enforcement discretion. | No pre-approval required; notification must be sent to FDA. |
| Claim Language | Direct statement of substance-disease relationship. | Must include a qualifying statement indicating uncertainty. | Describes nutrient's role in body structure/function. |
| Disease Reference | Refers to disease or health-related condition risk reduction. | Refers to disease or health-related condition risk reduction. | Cannot reference or imply treatment or prevention of a disease. |
| Example | “Adequate Calcium may reduce osteoporosis risk”. | “Scientific evidence suggests...that whole grains...may reduce the risk of type 2 diabetes”. | “Vitamin D supports immune function”. |
How to Navigate Health Claims as a Consumer
To make the best choices for your diet, it's crucial to look beyond the marketing and understand the context of the claims being made.
- Read the Small Print: Pay close attention to the disclaimer for qualified and structure/function claims, especially on dietary supplements.
- Check the Evidence: For structure/function claims, be aware that manufacturers are not required to submit their evidence to the FDA for review, but they must be able to substantiate the claim if challenged.
- Examine the Whole Product: A product may carry a health claim but still be high in sugar, fat, or sodium. Always read the Nutrition Facts label to understand the product's full nutritional profile.
- Look for Reputable Sources: Check if the health claim has been authorized by a recognized body like the FDA, as these are subject to the highest level of scrutiny.
- Consult a Professional: For serious health conditions, relying on a food label is never a substitute for advice from a healthcare provider or a registered dietitian.
Conclusion
Understanding what are health claims on food products is vital for modern consumers. They serve as a powerful marketing tool but are also regulated statements about a food's potential health benefits. By distinguishing between authorized, qualified, and structure/function claims, and by always cross-referencing with the Nutrition Facts panel, you can cut through the marketing noise. Relying on scientifically validated information and understanding regulatory oversight empowers you to make informed decisions that support a healthy and balanced diet.
