Vegetables and beans, especially soybeans, as well as sesame paste, melon seeds, nostoc, kelp, and shrimps, etc., contain a lot of calcium. Oxidation in living organisms can produce chemically active groups, called free radicals, which can cause peroxidation of lipids in cell biomembranes, destroying biomembranes, leading to cell disease and even death. Free radicals cause the human body to gradually age and even suffer from diseases such as cancer , cardiovascular and other important causes of diseases, and food contains antioxidants, including vitamin A and carotene, vitamin E, vitamin C, selenium, cysteine, etc. You can choose foods rich in these nutrients.
