^aValues for energy, protein, and associated nutrients are expressed as average daily nutrient intakes and based on moderate activity levels and reference body weights of 79 kg (174 lb) for military men and 62 kg (136 lb) for military women.

^b RDA values represent those for adults ages 19–50 years old.

^c AI = Adequate Intake. Data were insufficient to determine an RDA. AMDR = Acceptable Macronutrient Distribution Range. This is the percentage of energy intake that is associated with reduced risk of chronic disease and provides adequate amounts of essential nutrients.

^d Energy recommendations for various activity levels are estimates only and vary among individuals. The general values are for moderate levels of activity and are appropriate for most personnel in garrison. Values are rounded up to the nearest 50 kcal.

^e The RDA for protein is based on 0.8 g/kg/day; the MDRI for protein was based on 0.8–1.5 g/kg/day.

^f Expressed as mg/day as niacin equivalents (NE). 1 mg of niacin = 60 mg of tryptophan.

^g Expressed as μg/day as dietary folate equivalents (DFEs). 1 DFE = 1 μg food folate = 0.6 μg of folic acid from fortified food or as a supplement consumed with food = 0.5 μg of folic acid from a supplement taken on an empty stomach.
