Side effects of lactoferrin on babies

1、 Side effects of lactoferrin on babies

Lactoferrin is a safe and reliable natural substance extracted from milk, which has no side effects on baby.

1. Promote the absorption of iron by human body. After the baby sucks the breast milk, the lactoferrin in the breast milk in his digestive tract will combine with iron with high affinity, transport the iron to the small intestine cells and release the iron to meet the needs of the baby's whole body.

2. Another special function of lactoferrin is bacteriostatic, bactericidal and antiviral, and it is harmless to probiotics (such as bifidobacteria) in human body.

3. Lactoferrin can also promote and enhance the immune function of neutrophils, macrophages, natural killer cells and other immune cells in the human body, and it can also regulate and perfect the production of body antibodies, and even some studies have shown that lactoferrin can also promote the growth of brain cells and bones, as well as the anti-oxidation function and so on. Lactoferrin is widely distributed in human milk and animal milk. It has the functions of anti-bacterial, anti-virus and regulating body immunity, especially regulating immunity and resisting pathogenic microorganism. Known as "the first line of defense for health".A large number of studies have proved that lactoferrin, which appears in the eyes, respiratory tract, digestive tract and reproductive tract, provides the first and most important defense line for the human mucosal system which is invaded by a large number of pathogenic microorganisms every day.

2、 The difference between lactoferrin and whey protein

Lactoferrin lactoferrin is a red protein obtained in 1939 when people separated whey protein. Pure lactoferrin is red because of its iron content. It was not until 1959 that the red substance was identified as an iron binding glycoprotein called lactoferrin. The content of lactoferrin in human milk is relatively rich, accounting for about 20% of the total protein of human milk; the content of lactoferrin in milk is lower, accounting for about 3% - 4% of the total protein of milk; the content of lactoferrin in colostrum is generally higher than that in mature milk.

Lactoferrin powder on the market is the core nutritional protein extracted from milk (1g lactoferrin can be extracted from every 14kg of milk). 87% of whey protein milk is water, 13% is milk solid, and 27% of milk solid is milk protein. Only 20% of milk protein is whey protein, the rest 80% is casein, so the content of whey protein in milk is only 0.7%. The bioactive compounds contained in whey protein are α - lactalbumin, β - lactoglobulin, serum albumin, protease, lactoferrin, mixed protein and peptide, immunoglobulin and so on. Because of the existence of these bioactive compounds, whey protein has the characteristics of high nutritional value, easy digestion and absorption.

3、 What is lactoferrin

Lactoferrin is one of the main components of whey protein, accounting for 10% - 15% of the total milk protein. It is widely distributed in human milk and mammalian milk. It is the core immune protein in human milk, which can help improve immunity and reduce the incidence of disease.

Lactoferrin in its natural state is mostly unsaturated, pink in color, and the complex formed by combining with iron is red, so it is also called "red protein".

Lactoferrin can inhibit the growth of bacteria, destroy the bacterial cell membrane and kill bacteria. Lactoferrin (lactoferrin) can enhance immunity and inhibit infection caused by virus, such as rotabacteria and enterobacteria 71 in enterovirus, so as to maintain intestinal health. Lactoferrin (lactoferrin) is particularly important for the growth and development of infants and young children. It can help to resist harmful microorganisms such as bacteria and viruses, and enhance the hematopoietic function. This is the reason why "babies who eat breast milk are less sick".

In addition to infants, lactoferrin is also suitable for pregnant women and those with low immunity. It can help to promote iron absorption, prevent anemia, repair and improve the immune system, and enhance disease resistance.

4、 How to choose milk powder containing lactoferrin

1. Select the milk powder marked "lactoferrin" on the package

In infant formula milk powder, although lactoferrin has achieved a breakthrough in "breast milk level", there are not many brands that can be achieved at present.How to check whether the formula you choose contains lactoferrin? Is the content at breast milk level? The answer can be found in the "nutrition table" on the milk powder packaging.

Parents should pay attention to the packaging of milk powder when selecting milk powder containing lactoferrin: lactoferrin (lactoferrin) is "included" in the nutrition composition table, that is, this milk powder contains lactoferrin; if "no" lactoferrin, it means that this milk powder does not contain lactoferrin, or the content is very low.

2. Lactoferrin and prebiotics have better matching effect

Intestinal tract is the largest immune organ in human body, and the status of intestinal flora will directly affect the health of intestinal tract. When buying, if the formula also contains prebiotics, it can double protect the intestinal health and enhance the baby's resistance.

3. Lactoferrin ≠ whey protein, whey protein

Some formulas do not contain lactoferrin, but contain whey protein or whey protein. The latter two have different functions.

Whey protein is a kind of protein extracted from milk. It has the characteristics of high nutritional value, easy digestion and absorption, and contains many kinds of active ingredients. It is recognized as a high-quality protein of human body
