Which term refers to the role in how the body uses food to maintain health?

• A. Fiber
• B. Nutrition
• C. Exercising
• D. Reading

Answer: (B)

Nutrition is the term that describes how the body uses food to stay healthy. It covers how nutrients from what we eat are digested, absorbed, and metabolized to provide energy, support growth and repair, and maintain bodily functions. Without this broader view, you’d miss how all parts—carbohydrates, proteins, fats, vitamins, minerals, and even fiber—work together to keep the body in balance. Fiber helps digestion, but it doesn’t describe the entire process of how the body uses food. Exercising relates to activity, and reading has no connection to how the body processes food. So, nutrition best fits the idea of how the body uses food to maintain health.
