Study Notes
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.
