To whom watermelon may be contraindicated ? The doctor explains
However, it is important to remember that the glycemic index of watermelon is very high, and there is also a lot of fructose and sugar in the pulp. Therefore, people with obesity and diabetes should absolutely not abuse this summer berry.
The benefits of consumed fish outweigh the harm
Because of the powerful diuretic effect, those who suffer from stones also need to be careful with watermelon in the kidneys. Watermelon can cause stones to move.
