Share Breast milk contains more than 700 bacteria and the function they fulfill is a mystery

It is curious to realize that breast milk, which is the food that humans have taken for thousands and thousands of years, still carries many mysteries waiting to be unveiled .

A recent study conducted by a group of researchers from the Institute of Agrochemistry and Food Technology (IATA - CSIC) and the Higher Center for Public Health Research (CSISP - GVA) has revealed that breast milk contains more than 700 bacteria, something that leaves us speechless with more than one, and the authors acknowledge that they still do not know what role such a variety of bacteria plays in the health of the infant.

The study, which has been published in the "American Journal of Clinical Nutrition", has been done using a technique based on the massive sequencing of DNA that has allowed them to identify the different bacteria of several samples of colostrum and mature milk.

To do the tests, they analyzed samples of colostrum and milk after one and six months of lactation and found the more than 700 bacteria mentioned, which turned out to be quite more than those expected by the researchers.

The bacteria most present in the colostrum samples are: weissella, leuconostoc, staphylococcus, streptococcus and lactococcus. In the mature milk, in addition, typical bacteria of the mouth were found like veillonella, leptotrichia and prevotella. This is something that the authors do not dare to explain because they could be bacteria that are in the mouth by colonization of the milk and could also be bacteria from the mouth of the infant that entered the breast milk to change its composition.

Not all women have the same milk

The researchers wanted to base their research on how the composition of the milk varied among the different women and whether the way of giving birth had an impact on it.

Well, they noted that the milk of overweight women and those who gained more kilos than recommended during pregnancy contains less diversity of species and also saw that the milk produced by women who deliver by scheduled cesarean section is poorer in microorganisms than that of women who give birth vaginally . Interestingly, when the cesarean was not scheduled, when it was carried out while the woman was already in labor, the composition of the milk turned out to be practically the same as that of the women with vaginal deliveries.

Much to discover

Now, after knowing that colostrum and breast milk are full of microorganisms and bacteria we just need to know what function they have . If already with what little we know about breast milk we have clear that there is nothing that can replace it, more knowledge can help even more to be clear that there are many efforts that mothers, fathers and health professionals have to carry out to achieve that Every woman who wants to breastfeed her children can do it.
