Understanding Structure/Function Claims for Your RD Exam

A dietary supplement stating "Vitamin K helps support normal blood clotting" makes which type of claim?

• A. Health claim
• B. Nutrient claim
• C. Structure/function claim
• D. Qualified health claim

Answer: (C)

The statement “Vitamin K helps support normal blood clotting” is categorized as a structure/function claim. This type of claim typically describes the role of a nutrient or dietary substance in maintaining normal physiological functions or supporting health. In this case, it indicates that Vitamin K has a specific function related to blood clotting, which is a normal bodily process. Structure/function claims are distinct from health claims, which may imply a relationship between a substance and a disease or health-related condition. Nutrient claims generally refer to the level of a nutrient in a food product, such as "high in fiber" or "low in fat." Qualified health claims are also related to health claims but are backed by less scientific evidence, often incorporating language that qualifies the association, such as "may reduce the risk of." The direct reference to the function of Vitamin K in blood clotting underlines its importance in bodily processes rather than making a broader health claim about disease prevention or health promotion. Thus, this statement accurately fits the category of a structure/function claim.
