What is the recommended percentage of total calories that should come from protein?

The correct choice indicates that the recommended percentage of total calories from protein is between 10-15%. This range aligns with dietary guidelines suggested by various health organizations, which advocate for a balanced intake of macronutrients to maintain optimal health.

Proteins play several critical roles in the body, including building and repairing tissues, serving as enzymes and hormones, and supporting immune function. Ensuring that an adequate percentage of calories come from protein helps to maintain muscle mass, especially in populations at risk of muscle loss.

The recommended range helps ensure that individuals receive enough protein to support these functions without overly restricting caloric intake from carbohydrates and fats, which are also essential for energy and nutritional balance. Consuming protein within this percentage can lead to better health outcomes and nutrition stability, supporting overall dietary quality.
