Institute of Medicine (IOM) recommends somewhat lower intakes, ranging from
45 to 65 percent of calories from carbohydrates. 3Both organizations agree that whole plant foods, such as vegetables, fruits, whole grains, legumes, nuts, and

These health authorities set the lower end of the recommended carbohydrate
range (45 to 55 percent of calories) to ensure that people eat enough
carbohydrates to meet energy needs. The lower limits also ensure ample intakes
of the beneficial compounds associated with carbohydrate-rich foods: fiber,
minerals, vitamins, antioxidants, and phytochemicals.
