Breast milk nutrition facts:

  • The fat content in breast milk is related to the degree of fullness of the breast. When the breast is full, there is less fat content. When it is well-drained, there is more fat content.
  • The fat content in breast milk increases gradually throughout a feeding.
  • However, ALL components of breast milk are essential for the growth of your baby, not just its fat content.
  • If someone has ever told you that your breast milk is "low fat," they may not understand how milk production works and how dynamic breast milk is.
  • The most important thing is that your baby is thriving, regardless of the fat content of your breast milk.
  • The fatty layer in pumped milk is not a good determinant of whether you have "low fat" breast milk or not, as it only provides a snapshot in time and doesn't accurately represent your total fat yield in a 24-hour day.
  • According to research from Kellymom: The volume of milk intake (not the amount of fat in that milk) is the only thing that has been correlated with infant growth in exclusively breastfed babies.
  • Breast milk is a complex and dynamic fluid that changes in composition and volume based on a variety of factors, including the baby's age, feeding patterns, and the mother's health and diet.
