How much carbohydrate is in breast milk?
Lactose accounts for most of the carbohydrate in human milk. The concentration of lactose in mature breast milk is about 70 grams per liter and may be affected by the mother’s diet. Lactose is broken down into galactose and glucose which provide a rapid energy supply to a growing infant. Lactose intolerance is extremely rare in newborns and infants, but becomes a common problem in older children and adults.
