Nutrition and lactation.

Recommended dietary allowances for women during pregnancy are discussed in the light of actual intakes both in the developing and industrialized countries. The difference between total energy intakes in the industrialized countries (around 2900 kcal) and in the developing countries (around 1600 kcal) is emphasized. Data are provided from The Gambia which demonstrate the effect of seasonal changes in maternal dietary intake on the quantity of breast milk produced and on its quality. The relationship between breast-milk supply and infant growth is also demonstrated.
