Two results, although not yet conclusive, shed disturbing light on excessive salt consumption in the diet .
For excessive consumption, 12 grams of salt was taken as an example, the equivalent of 3-4 heaped teaspoons per day per capita. A group of mice was subjected to an excessive consumption of salt in the diet that corresponded to this amount in humans.
The mice were monitored for 12 weeks, and researchers at Melbourne’s Baker Institute found that excessive salt consumption resulted in over-active immune systems.
An overactive immune system that, however, had consequences on the bones of the mice. The bones showed small holes, exactly like the effect of severe osteoporosis
But this would not be the only danger of an excess of salt in the diet.
Another study, this time by a German institute, would have found a reduction of bacteria of the genus Lactobacillus in mice that eat too much salt in their diet.
This kind of bacteria belongs to the so-called “good bacteria” of the intestine.
Those that regulate body weight, immune system and metabolism.
It would be the lack of these bacteria to then determine hypertension in those who take more salt. But also overweight, hypertension, diabetes.
On both studies, however, there is a clarification to be made. Nice big.
- For some time, previous studies have found that a higher consumption of salt increases not only the body’s immune activity, but also the metabolism .
This is easily verified by doing a body temperature test.
- However, a higher metabolism must be accompanied by more nutrients. Otherwise the body literally consumes itself. Not surprisingly, mice subjected to an increase in salt in the diet show a greater appetite, following the metabolic increase, of 25%.
- This was also found in a study on astronauts. They had to eat 25% more food to maintain the same weight as their salt intake increased.
- If, on the other hand, the diet is maintained as before, the consequence is a consumption of the organism.
- Imagine that you have a higher than normal metabolism. What happens if you eat less than your body requires?
Lose weight. But don’t just lose fat. You also lose musculoskeletal tissue. This is until your metabolism slows down, as you obviously can’t lose weight forever.
- Similarly, we can imagine that the same thing happens in the bacterial flora. Bacteria become more aggressive because they try to extrapolate more nutrients from food, in order to meet energy needs.
Similar studies, which are still at a primordial stage, of observation, and more on mice, but say nothing else and above all do not take into account the previous scientific literature, can create more confusion than clarity on the consumption of salt in the diet.
- Add to this the fact that foods with more salt often contain more fat, and more calories.
So talking about salt that causes diabetes, overweight or osteoporosis is naive if you do not have an idea of the calories consumed per capita, the type of foods chosen, the daily amount of fat.
