The changes of minerals intake of lactating women through different lactation stages (N = 468, * significant differences compared with other lactation stages).
(a) Lactating women in 5–11days and 12–30days postpartum had a significant lower intake of calcium, phosphorus, potassium and magnesium comparing women in the 31–60day, 61–120days and 121–240days post-partum.(b)Lactating women in 5–11days and 12–30days postpartum had a significant lower intake of zinc, copper, manganese and iron comparing women in the 31–60day, 61–120days and 121–240days post-partum.
