The recommendation given by the Dietary Guidelines for Americans is that approximately more than half the calories consumed each day should be from carbohydrates, according to Mayo Clinic. The percentage of carbohydrates is between 45 and 65 percent of the daily calorie intake. Carbohydrates are important macronutrients that the body requires for energy.
Two types of carbohydrates can be found in diets: simple and complex. Simple carbohydrates are mainly sugars contained in fruits, vegetables and many processed foods. Complex carbohydrates include starches and dietary fiber. Dietary fiber foods include whole grain breads, beans, legumes, oatmeal and fiber-rich fruits and vegetables.
It is important that a diet consists of 14 grams of dietary fiber per 1,000 calories consumed each day, according to the CDC. Simple sugars should be limited in a diet.
