For many years, doctors blamed the formation of stones in the kidneys of calcium. Therefore, people with this disease had to severely limit the number of foods with this element in their diet. The logic of doctors is clear - in the kidney stones contains a lot of calcium oxalate, which means that he is responsible for this problem.
But recently, scientists at Harvard University have proved that everything is just the opposite.
Four years of observations for 45 thousand patients - and here is the result: the more calcium in human food - the lower the risk of stones.
The explanation of this fact is this: calcium prevents the absorption of the body of oxalate (the real "culprit" of stones). Just do not hope that in the same way will also "work" and calcium from vitamin complexes. Alas, it will not help you.
