Unexpected disclosures of breast milk

As we all know, all mammalian bodies have mammary glands. One of the main functions of this department is to produce baby milk. Particularly in humans, breast milk contains many other interesting things you may not have heard of.

Both men and women carry identical mammary glands until puberty. At this time, hormones will change the shape of the chest part depending on gender. For women, whether or not they give birth and breastfeed, it does not affect the development of the breast. However, some of the information below will likely surprise you.

First , returning to the Renaissance, Dr. Bernadino Ramazzini was considered the first person in history to give a warning: the rate of breast cancer in nuns (those who did not give birth) was much higher. with other women. Today, modern science has demonstrated specifically that if the first-born and lactating woman before the age of 20 years, the risk of breast cancer is reduced by about half compared to those who did not give birth or were born after 30 years of age. .

Up to 600 different bacterial species can be cultured in breast milk.

Secondly , according to the study of Dr. Jennifer Hahn Holbrook and colleagues, nursing mothers from their milk sources tend to be twice as aggressive with the group of mothers who give formula formula or never pregnant. In addition, their blood pressure also increased less. Hann Holbrook surmised this came from instinct. In the past, human ancestors often became like that to prevent beasts from robbing their children and if attacked, they would protect them to the end.

Third , in the 15th meeting of the International Conference on Human Milk and Breastfeeding Problems (ISRHML) in Lima, Peru, recently, molecular biologists, biochemists and genetics also revealed many unexpected things.

For example, we always think that breast milk is completely sterile. However, in fact, up to 600 different species of bacteria can be cultured in it with a process that scientists still cannot clarify. It is similar to a yogurt - dairy food, fermented by adding a microbial mixture.

In terms of nutrients, besides the basic group in breast milk, fat, protein, carbohydrates, vitamins A, C, E, K, and other essential minerals have a mysterious ingredient called oligosaccharide . Oligosaccharide is a type of carbohydrate made up of short chains containing several single lines connected. The oligosaccharide collection changes according to the mother's blood type. It is worth mentioning why this substance exists while the infant cannot digest oligosaccharide? This is a question that currently has no satisfactory answer.
