Which nutrient primarily provides insulation and protection for body organs?

• A. Proteins
• B. Fats
• C. Carbohydrates
• D. Vitamins

Answer: (B)

Insulation and protection for body organs come from stored fat, or adipose tissue. Subcutaneous fat lies under the skin and helps reduce heat loss, while fat that surrounds internal organs cushions them from bumps and trauma. That makes fats the nutrient most responsible for insulation and protection. Proteins mainly build and repair tissues, carbohydrates provide quick energy, and vitamins support metabolism in smaller amounts—none of these primarily insulate or cushion the body like fat does.
