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 components in foods that an organism uses to survive and grow. Macronutrients provide the bulk energy an organism's metabolic system needs to function while micronutrients provide the necessary cofactors for metabolism to be carried out. Both types of nutrients can be acquired from the environment. Micronutrients are used to build and repair tissues and to regulate body processes while macronutrients are converted to, and used for, energy. Methods of nutrient intake are different for plants and animals.
