The components of breast milk change over time

Breast milk has various advantages, one of which is that it contains well-balanced nutrients, including fat, lactose and protein as main ingredients. The proportions of these ingredients are automatically adjusted at different times to match the growing needs of a baby. This makes breast milk the best food for your baby.

Breast milk components and their functions

The main components of breast milk are fat, lactose and protein.

  • Fat is an important ingredient in the development of your baby’s brain and in the maintenance of the body structure.
  • Lactose is a source of energy and makes up the largest proportion (among fat, lactose and protein) in breast milk.
  • Protein is broken down into amino acids when it is absorbed into your baby’s body & becomes a source for building muscles. It also contains important immunoproteins such as lactoferrin and IgA.
