Which of the following is an example of a structure-function claim?

A structure-function claim is a statement that describes the role of a nutrient or dietary ingredient intended to affect normal structure or function in the body. They do not require evidence from scientific studies to be used, making them different from health claims, which need specific qualifications and must be based on scientific evidence.

The statement "Builds strong bones" clearly illustrates this concept as it refers to how a nutrient, such as calcium or vitamin D, supports the skeletal structure and function. It implies a direct relationship between the intake of that nutrient and the physical condition of bones, which aligns perfectly with the idea of maintaining or promoting health through nutritional intake.

In contrast, the other statements reflect different types of claims. For instance, "Helps reduce cholesterol" and "May prevent heart disease" suggest potential health benefits based on evidence, categorizing them as health claims rather than structure-function claims. "Low in saturated fat," on the other hand, is a factual statement about nutrient composition without implying a specific function or structural benefit to the body. Thus, the emphasis on the supportive role of nutrients in maintaining physical structures is what makes "Builds strong bones" the main example of a structure-function claim.
