Scientists discover how calcium is absorbed during childhood to build bones

Exploiting the way children absorb calcium to build their own bones may now be possible when a group of researchers, who published their study on Cellular and Molecular Gastroenterology and Hepatology, made a major discovery in this regard.

This same discovery could, in fact, be used to treat osteoporosis and all diseases related to bone fragility. Children, when they are breastfeeding and in general in the very first phase of life, are in fact able to absorb calcium as never will be repeated throughout their lives.

This is because they have to build healthy bones that will be the backbone of the entire organism for life. Mineral deposition for bone building then begins to decline sharply around the age of 25.

Researchers have identified channels for absorbing calcium in the small intestine of breastfed mice. This is particularly the case in two-thirds of the lower tract. It therefore seems to be the opposite of what happens in adult mammals: in the latter, most of the absorption of calcium occurs in the upper part of the small intestine.

According to pediatric nephrologist Todd Alexander, principal author of the study, the discovery of this mechanism could be an important first step in reversing the causes that lead to bone weakness all best humans.

Now the same researchers intend to perform the same kind of research on pigs that, physiologically speaking, are even more similar to humans than mice.
