Question

Which of the following is NOT one of the nutrients found in breast milk after the first week?

1) colostrum
2) fat
3) lactose
4) growth factors
5) antibodies

Answer 1

Colostrum is not found in breast milk after the first week; it is replaced by transitional milk and then by mature milk that contains fat, lactose, growth factors, and antibodies.

Step-by-step explanation:

The nutrient not found in breast milk after the first week is colostrum. Colostrum is the milk that is produced in the first few postpartum days and is rich in immunoglobulins, which help to boost the newborn's immune system. After about three postpartum days, it is replaced by transitional milk and then by mature milk around postpartum day 10. Mature breast milk contains many essential nutrients like fat, lactose, growth factors, and antibodies.
