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

The USDA guidelines recommend that 45-65% of daily calories should come from carbohydrates. This range has been established to ensure that individuals consume an adequate amount of carbohydrates to meet their energy needs, as carbohydrates are the body's primary source of energy. They play a crucial role in fueling physical activity and supporting bodily functions, particularly for the brain and muscles during exercise.

Carbohydrates also come with valuable nutrients, including vitamins, minerals, and dietary fiber, especially when sourced from whole-grain products, fruits, and vegetables. By adhering to the recommended percentage, individuals can promote overall health, maintain energy levels, and reduce the risk of chronic diseases associated with inadequate or excessive carbohydrate intake.

This recommendation balances the need for carbohydrates with the necessity of including other macronutrients, such as proteins and fats, in a healthy diet. The established range provides flexibility, allowing for individual dietary preferences and needs while ensuring that a substantial proportion of caloric intake supports optimal nutrition.
