According to the Average Macronutrient Distribution Range (AMDR) 10-35 percent of the average adultâs daily kilocalorie intake should come from protein, which is approximately 50-175 grams per day. The average intake in the United States falls in between that range at about 80 grams per day.
Nutrients are substances needed for growth, metabolism, and for other body functions. Macronutrients are nutrients that provide calories or energy. The prefix makro is from the Greek and means big or large, used because macronutrients are required in large amounts.There are three broad classes of macro-nutrients: proteins, carbohydrates, and fats.arbohydrates are roughly 50% oxygen, and like fats, they usually have less than 5% nitrogen or none at all. Proteins, on the other hand, consist of 15-25% nitrogen and about an equal amount of oxygen. The three macronutrients are often found together in most foods, but in varying amounts, or alone in other foods.
