GFD, general food distribution; DFE, dietary folate equivalents; IU, international units. *Because there is not a recommended absolute amount of fat for pregnant or lactating women, the recommended per cent of energy from fat is displayed in the ‘% daily intake’ column. For this physiological group, the per cent of energy from fat is recommended to be between 20 and 35% of energy (Institute of Medicine). †Amount of absorbed iron presented based on calculated bioavailability of diet. For lactating women, using standard equations for determining the bioavailability of iron from the diet, the calculated iron absorption from the ‘typical’ GFD ration for lactating women is 7%. Adequacy based on absorbed iron requirement. ‡Amount of absorbed zinc presented based on calculated bioavailability of diet. For lactating women, using standard equations for determining the bioavailability of zinc from the diet, the calculated zinc absorption from the ‘typical’ GFD ration is 21% (an increase of 10% above pregnancy). Adequacy based on absorbed zinc requirement.
