Human Milk Composition

Human infants are nourished via lactation, a process shared with other mammals.
Human milk is more than just sustenance; it contains infection-fighting chemicals and growth hormones.
Human milk composition differs from non-human mammal milk, and has evolved to meet the unique needs of human infants. Composition is highly complex.
Breast milk composition varies over time.
Colostrum, the first milk produced after birth, is rich in growth factors and infection-fighting substances.

Milk Composition Overview

Human milk is roughly 87% water, 3.8% fat, 1.0% protein, and 7% lactose.
Fat and lactose provide energy, increasing in proportion to the infant's age.
Milk protein quality changes with the infant's age for optimal growth.
Milk also contains essential vitamins, minerals, digestive enzymes, and hormones.

Energy and Fats in Milk

Fats are the primary energy source in human milk (40%-55%).
Human milk contains over 200 different fats, including all essential fatty acids.
The fat content increases during longer feeding sessions.
Fore-milk (initial milk) is higher in water and lactose, which is hydrating.
Hind-milk (later milk) has higher fat content, satisfying hunger.
The mother's diet can influence the fat content and essential fatty acid profile of the milk.
Some fats in milk can inhibit bacterial growth.
