Can you explain in detail how breast milk enhances the immunity of infants ?

Certainly. Breast milk can enhance the baby's immunity mainly through the following reasons:

1.Immunooglobulins: Breast milk contains a variety of immunoglobulins, such as IgA, IgM, IgE, which can fight against pathogens and protect the baby's intestines and respiratory tract mucosa from bacterial and viral invasion.

2.Immune cells: Breast milk contains living immune cells, such as T lymphocytes, B lymphocytes, macrophages, which can phagocytize and kill pathogens.

3.Lactoferrin: Breast milk contains lactoferrin, which has anti-infection effects and can bind iron and prevent its growth.

4.Lysozymes: Breast milk contains lysozymes, which can kill bacteria.

5.Bifidobacterium factors: Breast milk contains bifidobacterium factors that can promote the growth of bifidobacteria, which can inhibit the growth of harmful bacteria.

6.Antiviral and antiparasitic factors: Breast milk contains antiviral and antiparasitic factors that can help the baby resist viral infections and parasite infections.

7.Protective antibodies: Colostrum contains more antibodies and other anti-inflammatory proteins than mature milk, which can protect the baby from infection.

8.White blood cells: Breast milk contains white blood cells that can help prevent infections, especially in newborn babies where infection is particularly dangerous.

9.Epidermal growth factor: Breast milk contains epidermal growth factor that can stimulate the growth and maturation of intestinal villi, providing protection for the baby.

10.Vitamin A: Breast milk contains vitamin A that helps reduce the severity of infections.

11.Antibodies: Antibodies produced by the mother due to infections enter breast milk and protect the baby from infection.

Therefore, breastfeeding significantly enhances the baby's immunity and helps reduce the risk of diarrhea, respiratory infections, and other infectious diseases.
