I used to chuckle at such questions too. Then he stopped.
And here's the thing
We are with you already discussed that saltthat can get stuck in our bones, joints and all kinds of connective tissue. This salt is packed in such a way that it does not draw on water, and there will be no swelling. It's actually not literally salt, but sodium. We eat it not only with sodium chloride (table salt), but also with various other products.
So this sodium sits in the bones and does not touch anyone. But if a person has to starve, then sodium in his blood for a very long time (maybe months) will be at a quite decent level, because it is slowly mobilized from the bones.
Isotopes
These miraculous transformations of sodium were very well studied 60 or even 80 years ago. And that's because sodium isotopes were used for this business. At that time, radiation was treated more simply. They took, for example, people who, for some good reason, had to open their chest. Sodium isotope was poured into such people at different times before the operation, then the rib was cut out for them and it was checked whether a lot of the isotope was removed from this rib. A very elegant study.
In short, sodium was slowly removed from there, and some of it was clearly stuck in the bones.
Here you can also add the brutal rice diet of a century ago, with the help of which people for a while saved from malignant hypertension. There, too, for several months it was necessary to limit sodium so that its reserves in the body were really depleted.
Children and bones
Somewhere in the seventies of the last century, it was rumored that high blood pressure could somehow be related to sodium stores in the bones. The idea arose that if a child during the period of rapid growth overeats salty, then he has a lot sodium will get stuck in the bones, and then from this in an adult state, blood pressure will scale. Very similar to the topic of our today's publication.
Researchers of that time even walked over American blacks (a common word at the time) that they had more bone mass, so their pressure was more often scaled.
As far as I know, this idea of infants' stores of harmful sodium has not been scientifically backed up.
Salt sensitivity
But the topic of salt-sensitive people with high blood pressure has become very popular.
Salt-sensitive people are called those who cannot effectively excrete sodium. Well, that is, a man ate a salted fish, and his blood pressure jumped. It is harmful.
At first they thought it was all about the kidneys. Like they do not remove sodium well. Then they decided that the same trick with the storage of sodium in bones and joints just helps subjects insensitive to salt to eat salty food without harm to their health. They eat sodium, and it goes into the bones and does not cause a jump in blood pressure. Then, in a calm atmosphere, this sodium will be gradually excreted by the kidneys and will not harm anyone.
Leather
Gradually, scientists' attention shifted from bones and joints to softer tissues like our skin. There, too, there are negatively charged proteoglycans, which bind positively charged sodium ions and do not just let it go anywhere. And a skin biopsy is more convenient to do than to drill bones.
Vascular endothelium
The latest trend is sodium retention by the vascular wall.
Our blood vessels from the inside (from the blood side) are lined with a layer of cells that are involved in the regulation of blood pressure. It turned out that on the surface of this layer of cells, like butter on a sandwich, a layer of those same proteoglycans and similar chemistry, which is also negatively charged and literally absorbs excess sodium from blood.
In laboratory studies, it was found that at least the daily amount of sodium eaten (in fact, rather much more) is easily retained by the wall of blood vessels and does not harm anyone.
Then it turned out that if you persistently overeat salty, then the absorption capacity of this wonderful layer ends, and the layer itself deteriorates. Well, roughly, as if you regularly stuff your pockets with stones. To some extent, this would be convenient, but then the pockets are torn, and you cannot put anything there at all. So something similar happens to the vascular wall.
After damage to the miraculous layer, it can no longer work as before, but will begin to pass sodium further into the cells in the vascular wall. The cells readily absorb this excess sodium, but for some reason they lose the ability to regulate blood pressure, and it begins to scale down.
Briefly speaking
Salt can get stuck inside our body for a long time, but it does not seem that these reserves have been there since childhood. Rather, if you overeat salty from a young age, then our arteries will simply lose the ability to cope with this sodium, and the pressure will scale down. From which the conclusion - do not abuse salty and do not teach children to this. It's not just eating habits. You will really rip your pockets for this sodium.
