Which statement best describes nutrition?

• B. Nutrition is the art of cooking meals.
• C. Nutrition is a field unrelated to disease prevention.
• D. Nutrition only concerns vitamin supplements.

Answer: (A)

Nutrition is the science that studies how food nourishes our bodies and influences our health. It covers how we obtain energy and nutrients from what we eat, how those nutrients are digested and used, and how dietary patterns affect growth, metabolism, immune function, and disease risk. This goes beyond just cooking or taking supplements, and it includes all nutrients, energy balance, and the impact of long-term eating habits on health. The other ideas miss the broader role of nutrition in disease prevention and overall bodily function, so this description best captures what nutrition is.
