Assimilation Of Nutrients By The Mammary Gland As Indicated By Delta C Analyses Of Dietary And Breast Milk Components
Nieve T. Librojo | Gerald L. Schroeder
Abstract:
The almost immediate assimilation of ingested foods into breast milk was demonstrated
by measuring changes in the breast milk's delta C values relative to changes in
diet delta C. The carbon of dietary carbonates accounted for over half the lactose and
protein fractions of the milk within 4 and 8 h, respectively, of the consumption of the
carbohydrate. The results support an understanding that the current diet of a nursing
mother intimately and rapidly effects the composition of her secreted milk.
