The main component of salt is sodium chloride. When we consume too much sodium ions, the kidneys will excrete the excess sodium through urine to balance the electrolytes in the body. In this process, calcium will also be removed.
For every 2,300 mg of sodium (equivalent to 6 grams of salt) excreted, 40-60 mg of calcium is lost. If you eat too much salt over a long period of time, the amount of calcium lost will be greater than the amount of calcium taken in. To maintain normal calcium levels in the blood, the body must take calcium from the bones. Over time, the bones will become brittle and weaker.
Especially for women, because estrogen levels decrease after menopause and bone loss increases rapidly, a high-salt diet increases the risk of osteoporosis.
Daily salt intake should be controlled below 5 grams. Salt sources are not only added during cooking, but also include invisible salts such as pickles, soy sauce, processed foods...
These foods are high in sodium. If you're not careful, you could end up with a serious salt overload.
