What percentage of daily calories should come from carbohydrates according to nutritional guidelines?

The recommendation that 45-65% of daily calories should come from carbohydrates aligns with established nutritional guidelines set by major health organizations, including the Dietary Guidelines for Americans. Carbohydrates are an essential macronutrient and serve as the body's primary source of energy. They play a crucial role in supporting physical performance, brain function, and overall bodily processes.

Consuming carbohydrates within this range ensures adequate energy intake for individuals with varying activity levels and lifestyles. Carbohydrates can be divided into simple carbohydrates (sugars) and complex carbohydrates (starches and fibers), with an emphasis on choosing whole, unprocessed sources like fruits, vegetables, whole grains, and legumes. The recommended range reflects an understanding that a balanced intake of carbohydrates can help maintain energy levels, support metabolic health, and promote overall well-being.

It's important to note that the other ranges provided do not support the energy needs and optimal carbohydrate intake that are beneficial for most people, particularly those engaged in regular physical activity. Thus, the 45-65% guideline is grounded in promoting a balanced and healthful diet.
