Food for Thought: Fighting Label Claims Through the Power of Knowledge

As you walk down the aisle of the grocery store, packages are practically yelling at you with different claims about their contents. ‘Good Source of Protein.’ ‘Low in Cholesterol.’ ‘Less Sodium than… ,’ etc., etc. It can be a vicious environment for consumers as those claims are unified by the same simple goal: they want you to buy the product. 

How do we make heads or tails of these claims, protect our wallets, and support our health from the questionable practices of marketing? With knowledge and information. One role of the Food and Drug Administration (FDA) is oversight and regulation of dietary claims. Let’s dive into the specifics: 

Three types of claims can be used on food and dietary supplement labels: Health Claims, Nutrient Content Claims, and Structure/Function Claims

1. Health Claims 

Health claims describe a relationship between a food substance and a reduced risk of disease or health-related condition (1). Within these claims there are two tiers: Authorized Health Claims and Qualified Health Claims. These two differ in the level of scientific evidence that exists to support them. 

Authorized claims have “significant scientific agreement,” providing a high level of confidence in the validity of the substance-disease relationship. Qualified claims, on the other hand, are supported by some scientific evidence but do not meet the significant scientific agreement standard. These qualified claims “must be accompanied by a disclaimer or other qualifying language to accurately communicate the level of evidence supporting the claim,” per the FDA.  There are a number of these qualified claims out there (many more than authorized claims) and we recommend really paying attention to the language and looking out for those disclaimers, to tell the difference. Here’s an example of a qualified claim: “Scientific evidence suggests, but does not prove, that whole grains (three servings or 48 grams per day), as part of a low saturated fat, low cholesterol diet, may reduce the risk of diabetes mellitus type 2.” (2) Note the disclaimer there. 

Authorized claims are a bit easier to spot because only a handful of relationships qualify with the more rigorous standards. Here is a list where there is significant scientific agreement on the relationship between the food substance and its effect on disease:

  • Calcium & Osteoporosis
  • Calcium, Vitamin D, & Osteoporosis
  • Dietary Fat & Cancer 
  • Sodium & Hypertension
  • Dietary Saturated Fat & Cholesterol & Risk of Coronary Heart Disease 
  • Fiber-Containing Grain Products, Fruits, Vegetables & Cancer 
  • Fruits & Vegetables & Cancer 
  • Folate & Neural Tube Defects
  • Dietary Non-Cariogenic Carbohydrate Sweeteners & Dental Caries
  • Soluble Fiber from Certain Foods & Risk of Coronary Heart Disease 
  • Plant Sterol/Stanol Esters & Risk of Coronary Heart Disease

Remember these relationships are the only ones which are supported by strong scientific evidence. No matter what is said about the effect of other substances on disease states, those listed here are the only relationships with significant scientific agreement.

2. Nutrient Content Claims

These describe the level of a nutrient in the product using specific terminology. They also can compare the level of a nutrient in a food to that of another reference food, known as a relative claim. There are quite a few specifications here so it’s easy to get lost in the weeds. Some key terms to be familiar with include:

NutrientTerm Definition
Calories Calorie Free / Zero Calorie<5 per serving 
Low Calorie<40 per serving 
Reduced Calorie / Fewer CaloriesAt least 25% less than appropriate reference food
Total Fat Fat Free<0.5g per serving
Low Fat3g or less per serving 
Reduced Fat / Less FatAt least 25% less than appropriate reference food
Saturated Fat Saturated Fat Free <0.5g per serving
Low Saturated Fat1g or less per serving & 15% or less calories from Saturated Fat
Reduced Saturated Fat / Less Saturated FatAt least 25% less than appropriate reference food
Cholesterol Cholesterol Free <2mg per serving 
Low Cholesterol20mg or less per serving 
Reduced Cholesterol / Less Cholesterol At least 25% less than appropriate reference food
Sodium Sodium Free <5mg per serving 
Very Low Sodium35mg or less per serving 
Low Sodium 140mg or less per serving 
Reduced Sodium / Less Sodium At least 25% less than appropriate reference food
Light in Sodium If reduced by 50% per serving 
No Salt Added or Unsalted Must declare “This is not a sodium free food” if not sodium free 
Sugars Sugar Free <0.5g per serving
Low SugarNot defined/ cannot be used 
Reduced Sugar / Less SugarAt least 25% less than appropriate reference food
Sugar AlcoholsNot included in scope of these claims

The table illustrates that the exact wording used means something highly specific. It’s important to remember that “Reduced” or “Less” means it’s a comparison to a reference food. This doesn’t mean it’s necessarily health-promoting. The comparison must be taken in context. For example, a cookie with “Less Fat” or “Reduced Calories” is still a cookie, it just has less of the nutrient in question than the reference cookie. Context is key! 

Other Points of Interest for Nutrient Content Claims

Claim: “Light”

What this means: Not much. According to the FDA, the term “Light” may be used to describe the nature of the product if it is deemed to appropriately describe its attributes. Furthermore, “if there has been a long history of use of the term ‘light’ associated with a product it may continue to be used.” These definitions for “Light” don’t hold a lot of weight so I wouldn’t pay much attention to them. 

Claims: “High” / “Rich in” / “Excellent Source of”

What this means: Contains 20% or more of Daily Value per serving. Based on a 2,000 calorie diet, these claims mean the product contains at least one fifth of your daily needs of the nutrient in question. 

Claims: “Good Source” / “Contains” / “Provides” 

What this means: Contains 10-19% of Daily Value per serving. Similar to the claim above here, but contains less of the nutrient. I think comparing the two nicely illustrates the nuances of specific language with these claims. The difference of 1% requires a different set of wording. 

Claims: “More” / “Fortified” / “Enriched” / “Added” “Extra” / “Plus”

What this means: Relative claim alert—10% or more of Daily Value per serving as compared to appropriate reference food. Again, these claims are relative and may only be used for specific things: vitamins, minerals, protein, dietary fiber, and potassium. 

Claims: “Lean” / “Extra Lean” 

What this means: These two apply to animal proteins and classify their respective fat content. “Lean” specifies less than 10g total fat and 4.5g saturated fat while “extra lean” specifies less than 5g total fat and 2g saturated fat.

Claim: “Antioxidant”

What this means: There are a few specific parameters for this one:

  1. A Reference Daily Intake (the daily intake level of a nutrient that is considered to be sufficient to meet the requirements of 97–98% of healthy individuals in every demographic in the United States) must be established for the nutrient in question
  2. The nutrient in question must have existing scientific evidence of antioxidant activity
  3. The level of the nutrient in question meets a minimum of the criteria of a “Good Source.”

Claims: “Healthy” 

What this means: In order for a product to consider itself “healthy” it must qualify as both low in total fat (3g or less) and saturated fat (1g or less) per serving and must have less than 480mg of sodium. It also must contain at least 10% of the Daily Value per serving for Vitamins A and C, calcium, iron, protein, and fiber. 

3. Structure Function Claims

These are the third and final type. Structure function claims describe the effect that a substance has on the structure or function of the body but does not make reference to a disease. These tend to be rather straightforward as they are not making claims about the product itself. For example, “calcium builds strong bones.” (3) Nothing about the product, just a fact about calcium. These tend to be the simplest to decipher of the three groups because they are simply stating what is known, as defined by scientific evidence. 

Conclusion

It’s all marketing. If you remember that basic principle you will be in a good position to defend yourself as a consumer. Remember though there are three different types of claims, and the specific language used is very important. With relative claims, context is very important as well. Lastly, don’t be afraid to be an investigator. Check nutrient panels and ingredient lists for the most accurate information about a product.

Hopefully this post was insightful and helpful in cracking the code of label claims.
