Fig. 1 During the first 6 months of lactation, the protein supply to an exclusively breastfed infant decreases to about 55% of the initial values due to decreasing milk protein concentration. Milk protein intake is calculated as 75% of crude protein intake. (Data from World Health Organization. Protein and amino acid requirements in human nutrition.
