Many people want to believe that vitamin K strengthens bones in older people. The Japanese are especially sensitive to this. They published a bunch of studies in which they swore and swore that vitamin K is especially useful for Japanese bones.
The Japanese were so convincing that the Americans began to follow them. Ten years ago, they also believed very much in vitamin K.
Osteocalcin
Here it must be said that vitamin K is associated with bones through osteocalcin.
Osteocalcin is a regulator that is produced inside bones and regulates the construction of these very bones. It is clear that, like any regulator, osteocalcin is able to regulate both there and back.
You can imagine that vitamin K sets up osteocalcin for creative work, and he begins to strengthen bones. Under the influence of osteocalcin, bones pick up calcium better and, like concrete, strengthen their internal bone reinforcement with this calcium.
The idea that vitamin K is good for bones was also supported by the fact that vitamin K antagonists, which prevented bleeding, did not seem to work very well on bones.
Something went wrong
And so the Japanese believed in the magical power of vitamin K, and the Americans followed their lead. And then it turned out that the Americans got excited.
In the American scientific literature, refutations, excuses and excuses began to come across that conclusions about the benefits of vitamin K for bones were drawn from not very good research. Well, if all this is calculated properly, it turns out that if a person eats calcium and vitamin D, then there will be no additional benefit from vitamin K.
Yes, somehow everyone formulated it in a streamlined way.
Japanese
And what about the Japanese? Nobody scolded the Japanese. They continue to believe in the benefits of vitamin K for Japanese bones. At the same time, the rest of the world believes that the Japanese have the right to have bones that are very sensitive to vitamin K. Something like this…
Personally, it seems to me that the Japanese eat not only vitamin K with their favorite vegetables, but also calcium, which is really useful for bones. Because the Japanese eat less milk every year. So it turns out that it is more convenient for them to get calcium from vegetables, and along with it, vitamin K will also go as a bonus. Or maybe I'm wrong too.
