Breast milk
Breast milk
Breast milk (/brɛst mɪlk/), also known as mother's milk, is the milk produced by the mammary glands of a postpartum female to feed a child.
Etymology
The term "breast milk" is derived from the Old English words "brēost" (breast) and "meoluc" (milk).
Definition
Breast milk is the primary source of nutrition for newborns before they are able to eat and digest other foods. It contains a unique balance of nutrients that contribute to the health, growth, and development of a baby.
Composition
Breast milk is composed of several components including proteins, carbohydrates, fats, vitamins, minerals, and water. It also contains numerous bioactive molecules that aid in the immune defense of the infant.
Benefits
Breast milk provides numerous health benefits to an infant. These include a lower risk of asthma, allergies, obesity, and Sudden Infant Death Syndrome (SIDS). It also promotes cognitive development and supports the immune system.
Production
Breast milk production is regulated by the hormone prolactin. After childbirth, the levels of this hormone increase, stimulating the production of milk.
