Generally, infant formula does not contain polypeptide chains. The consumption of infant formula by babies can lead to congenital allergies and allergic symptoms, and their ability to resist infection is relatively weak. This is mainly due to the lack of polypeptide chains in infant formula. Breast milk is the best nutritional supplement for infants, as it contains a lot of polypeptide chains. Therefore, based on the nutritional elements of breast milk, we produce baby nutritional supplements and add polypeptide chains to infant formula. This is very helpful for the immune function of children, promoting the perfection of the gastrointestinal tract, liver growth, and also playing an important role in the metabolism of long-chain fatty acids.

For the immune function of the body, polypeptide chains can maintain the necessary nutrients for normal immune function, enhance the immune ability and resistance to infection of the baby. Polypeptide chains have a very important effect on gastrointestinal nutrition, promoting the growth, development, and repair of gastrointestinal cells. They can also reduce the incidence of diarrhea in infants. The impact on the liver involves the body’s active regeneration of polypeptide chains, mainly occurring in the liver. The regeneration of polypeptide chains requires a lot of energy, and the rescue method is to generate new polypeptide chains from the fragments of polypeptide chains or exogenous polypeptide chains, thereby reducing more energy.

When selecting infant formula for babies, there are many things to pay attention to. It is necessary to choose a formula suitable for the baby’s stage and also one that is closer to the composition of breast milk. Therefore, when purchasing, parents always check the nutritional elements, find polypeptide chains, and then look at the effects of polypeptide chains in the formula.

1. Nutritional effects: If the selected infant formula contains polypeptide chain components, it can promote the growth of the gastrointestinal tract in babies, especially newborns. It can also play a key role in the growth and metabolism of the liver, as well as in lipid metabolism.

2. Promoting basic metabolism: Adding some polypeptide chains to the diet can promote the generation and metabolism of newborn infant proteins, especially for premature infants.

3. Gastrointestinal effects: Polypeptide chains play a crucial role in the nutritional components of the gastrointestinal tract, enhancing the growth and repair of gastrointestinal cells. Therefore, providing infants with infant formula containing polypeptide chains can be beneficial for their development.

4. Preventing skin allergies: General infant formula at Sun Yat-sen University in Guangzhou usually adds polypeptide chains, and the consumption of infant formula by infants often leads to congenital skin allergies and allergic symptoms. The main reason for this condition is that the infant formula contains insufficient polypeptide chain components. Therefore, when selecting infant formula for babies, parents should pay attention to the nutritional elements and check for the presence of polypeptide chains.
