1 DFE, dietary folate equivalents; EAR, estimated average requirement; kcal, kilocalorie; RAE, retinol activity equivalent. 2 Estimated average requirements from [35,36,37,38]. Estimated energy requirement (EER) = 354 − (6.91 × age [year]) + PA × [(9.36 × weight [kg]) + (726 × height [m])] + physiological group adjustment, where physical activity (PA) = 1.27 (active), and physiological group adjustments were as follows: 2nd trimester pregnancy = + 330; 3rd trimester pregnancy = + 452; 0–6 month postpartum = + 330; 7–23 months post-partum = + 400. 3 Assumes vitamin A fortification of cooking oil at 11 mg/kg from [31] and folic acid and iron fortification of wheat flour at 2.5 mg/kg and 60 mg/kg, respectively [32]. Does not include iron and folic acid supplements.
