Acceptable Macronutrient Distribution Range (AMDR):  these guidelines indicate  percentages of total caloric intake that should consist of carbohydrate, protein, and fat. Carbohydrate:  45-65% protein: 10-35% fat: 20-35% 4. Define, explain the difference between:

Essential Nutrients generally produce, or produce in sufficient amounts; they must be obtained in the diet Non-essential Nutrients : substances required for normal growth and health that the body  can manufacture in sufficient quantities from other components of the diet. We don’t require a  dietary source of nonessential nutrients.
