The digestive system is considered as the biggest immune system of human body. The indigestible nutrients can't be well absorbed and utilized, which naturally affects the development of the baby's immune system. So what kind of milk powder is easy to digest and absorb? ?

First of all, we should know some digestible nutrients. ?

Sugar?

Lactose, galactooligosaccharides, fructooligosaccharides?

Lactose can provide energy for the baby's growth, and it is the driving force for the development and activities of organs, nerves, limbs and muscles in the baby. The development of baby brain cells and the health of the whole nervous system need a lot of lactose. There is enough lactase in the baby's digestive tract to decompose lactose, which can decompose, digest, absorb and utilize lactose well. Lactose can promote the reproduction and growth of lactic acid bacteria in the baby's intestine and protect the baby's stomach. Lactose can also promote the baby's absorption of calcium in the process of calcium metabolism, and its sweetness is low, which will not cause the baby to be picky about food; ?

Galactooligosaccharide is an important component of breast milk, which is made by β -galactosidase acting on lactose and belongs to oligosaccharides composed of glucose and galactose. It is not digested by human digestive enzymes and has good Bifidobacterium proliferation activity. Compared with other oligosaccharides, galactooligosaccharides can effectively promote the growth of various bifidobacteria and lactic acid bacteria in the intestine, which is a good food and soil for probiotics and better for baby's health. ?

Fructooligosaccharides, also known as fructooligosaccharides or fructooligosaccharides. It exists in fruits, vegetables and cereals. Fructooligosaccharide is a soluble dietary fiber, which can improve the proliferation of bifidobacteria and lactic acid bacteria in baby's intestine, regulate gastrointestinal flora to some extent, improve diarrhea and constipation, and enhance immunity. ?

Lipids?

Vegetable oil, OPO structured fat?

In milk, the baby needs less unsaturated fatty acids, so formula milk powder adjusts the structure of fat, removes some unsaturated fatty acids from animal milk, and selects vegetable oil containing more unsaturated fatty acids to adjust the proportion of fat in formula milk powder, which not only meets the baby's needs, but also improves the digestion and absorption rate of fat. Commonly used vegetable oils are walnut oil, peanut oil, rapeseed oil, soybean oil, sunflower oil, coconut oil, corn oil and so on. Some of them contain palm oil, but palm oil is easy to combine with calcium, causing constipation. So mom and dad can look at the choice of oil in their milk powder. ?

Compared with ordinary milk powder, OPO formula milk powder is characterized by its fatty acid structure. The structure of OPO structured fat formula is different from that of ordinary formula. The proportion of SN-2 palmitic acid in breast milk is 70%, while that of ordinary formula milk powder is only 10%. OPO formula milk powder is to simulate the molecular structure of breast milk lipid by enzymatic lipid exchange technology, so that the proportion of 2 palmitic acid is as high as 40% or more, which makes the formula milk closer to the level of breast milk and easier to digest and absorb. (chemical name of OPO: 1, 3- diglyceride 2- palmitate)?

Protein?

Whey protein, casein phosphopeptide (cpp)?

Among all kinds of protein, whey protein has the highest nutritional value. Generally speaking, the types and contents of essential amino acids are relatively complete and easy to digest and absorb. The whey protein in breast milk contains 60% and casein contains 40%, so the feces of babies who drink breast milk are soft and few. In addition, whey is rich in cysteine and methionine, which can maintain the level of antioxidants in human body. Many experimental studies have proved that taking whey protein concentrate can promote humoral immunity and cellular immunity, stimulate human immune system and prevent the occurrence of chemically induced cancer. Therefore, whey protein is a very good protein for enhancing immunity. ?

Casein phosphopeptide (CPP) is a bioactive polypeptide extracted from milk casein by biotechnology. CPP is a peptide chain derived from milk casein, which is not strictly from protein. It can chelate with calcium, iron and zinc, combine with phosphoric acid, oxalic acid and phytic acid to avoid precipitation, and effectively promote the absorption of divalent minerals such as calcium, iron and zinc.
