Which of the following is a structure-function claim? a. Fat-free b. Less sodium c. Supports immunity and digestive health d. A diet low in total fat may reduce the risk of some cancers ?

A structure-function claim focuses on how a product may influence the body's structure or function. In this case, "supports immunity and digestive health" is the correct answer, highlighting how the product may positively impact the body's systems. On the other hand, "fat-free," "less sodium," and the statement about reducing cancer risk are more related to nutritional content and health claims rather than describing a direct effect on the body's structure or function. Remember, structure-function claims are like friendly cheerleaders for your health!
