Notes

1. People with poor skin. When you eat a lot of salt, due to the effect of osmotic pressure, the water in the body tissues will decrease, and the water discharged from the body will increase, which is not conducive to the skin's water retention. Therefore, a low-salt diet is an important measure to improve skin quality.

2. People with bad stomach. Compared with foods with less salt, foods with too much salt will reduce the viscosity of the protective mucus in the stomach, making it less protective of the stomach wall. Various harmful substances in the food are more likely to act on the stomach wall, thus promoting The occurrence of stomach problems. Epidemiological surveys have shown that there is a positive correlation between salt intake and the risk of gastric cancer.

3. People with osteoporosis. When the sodium intake is too much, the body will work hard to excrete sodium, but at the same time, it will increase the excretion of calcium in the urine. For people with osteoporosis, this is simply adding insult to injury. Therefore, it is correct to follow the saying "less salt equals more calcium".
