What effects does calcium have on human health?

Supplementing calcium and strengthening bones before the age of 30 can reduce the risk of osteoporosis. If the strengthening effect is good, the bone loss after menopause will be reduced by more than 40%. Calcium supplementation and taking vitamin D pills (1200mg and 800IU respectively) can reduce the fracture rate by 20%. The National Institutes of Health suggested that the daily calcium intake of women who took estrogen before and after menopause was 65,438+0,000 mg, and that of postmenopausal women who did not take estrogen and all women over 65 years old was 65,438+0,500 mg. Foods rich in calcium include dairy products, canned salmon and sardines, leafy vegetables such as kale and turnip leaves, whole grains such as buckwheat, brown rice and quinoa, and many beans, including soybeans and bean products, such as tofu.
