What is the Institute of Medicine's recommendation for carbohydrate intake as a percentage of total daily calories?

The Institute of Medicine (IOM) recommends that carbohydrates should make up 45-65% of total daily caloric intake. This range is designed to ensure that individuals consume a balanced amount of macronutrients to support overall health and meet energy needs. Carbohydrates are a primary source of energy for the body, especially for the brain and during physical activity.

By adhering to this recommendation, one can achieve a diet that supports optimal metabolism and performance, while also providing adequate nutrients through carbohydrate-rich foods such as fruits, vegetables, grains, and legumes. This balance helps in maintaining healthy digestion and supporting physical activity levels.

The other options reflect either lower or higher percentages that do not align with the established guidelines, thereby potentially leading to inadequate energy intake or excess, which could detrimentally affect health and wellness.
