What is true of micronutrients?

• A. Micronutrients have no calories or nutritional value
• B. Micronutrients are the main energy source
• C. Micronutrients are inorganic
• D. Micronutrients are vitamins only

Answer: (A)

Micronutrients do not provide calories; they’re needed in small amounts to support metabolism and a wide range of bodily functions, but they don’t supply energy. Energy in the body comes from macronutrients—carbohydrates, fats, and proteins. Micronutrients include both vitamins (organic) and minerals (inorganic), so they are not limited to vitamins alone. Because of that, the statement that micronutrients have no calories is true in terms of energy content, and their value lies in enabling the biochemical processes that keep the body functioning, not in supplying energy themselves.
