Breast milk is rich in bioactive substances, especially colostrum. According to the current research progress, it is found that breast milk contains 13 kinds of growth factors, 68 kinds of cytokines, 4 15 kinds of protein, more than 200 kinds of breast milk oligosaccharides, a large number of medium-chain fatty acids and immune cells.

These substances provide immune protection for infants, promote the development of various organs of infants, prevent allergies, have protective effects, are easy to digest, and have healthy intestines.

According to the function, it can be roughly divided into the following seven types:

immune factor

Immune proteins IgA, IgM, IgG, lactoferrin, lysozyme, carrot-like, oligosaccharide, complement C3 protein, leukocytes, Bifidobacterium growth factor and antiviral mucin.

Immunoglobulin is particularly rich in early lactation, the most important form is secretory IgA(SIgA), followed by SIgG, which provides immune protection for infants until their own immune system matures.

With the maturity of infant's immune system function, the content of immunoglobulin in breast milk is gradually decreasing, which also reflects that the demand for immunoglobulin in breast milk is gradually decreasing.

Economic growth factors

Epidermal factor (EGF), nerve factor (NGF), insulin-like factor (IGF), transforming factor (TGF) and polyamine.

hormone

Lactation feedback inhibitor (FIL), insulin, prolactin, thyroid hormone, corticosteroid corticotropin, oxytocin, calcitonin, parathyroid hormone, erythropoietin.

Cytokines and anti-inflammatory factors

Tumor necrosis factor, interleukin, interferon, prostaglandin, α-antitrypsin, antitrypsin, platelet activating factor.

digestive enzyme

Salivary enzyme, bile salt-stimulated esterase, bile salt-stimulated lipase, lipoprotein lipase, ribonuclease.

migration rate

Lactoferrin (lactoferrin), folic acid complex, cobalamin complex, IgF complex, thyroid hormone complex, corticosteroid complex.

other

Casomorphin, sleep peptide, DNA, RNA

Why is breast milk the best food for babies?

Breast milk is a kind of liquid food with biological specificity, which is obviously different from all other nutritional substitutes such as milk and has unique advantages in infant feeding.

The composition of breast milk is changeable, and it will change with different lactation stages and eating habits.

Breast milk is rich in many beneficial factors, such as probiotics, growth factors, anti-inflammatory factors, cytokines and so on.

Except for the severe malnutrition of mothers, most mothers have the ability to produce adequate and high-quality breast milk;

Maternal nutritional status has the greatest influence on breast milk components, such as DHA, water-soluble vitamins and fat-soluble vitamins.
