Question

why nutritional requirements increase during lactation.

Answer 1

Your intake of some nutrients (e.g. vitamins C, A, thiamine, riboflavin, B6, B12, iodine and selenium) is reflectedin your breast milk composition. ... On the other hand, nutrients in your breastmilk such as zinc, iron, folic acid, vitamin D, calcium, and copper are not affected by what you eat.
