Magnesium maintains bones, metabolizes vitamins and other minerals, helps produce energy from food, it helps regulate body temperature, prevents buildup of calium and sodium, and it can even work as a laxative. Because it regulates calcium and sodium, which can interfere with blood flow, magnesium may help protect against high blood pressure and thus reduce the risk of heart attack and stroke. Most people do not maintain proper levels of magnesium.
For this reason, many people would greatly benefit from supplementing their diet with magnesium. Beans, Broccoli, Halibut, Nuts, Okra, Oysters, Plantain, Rockfish, Seeds, pumpkin and squash, Soy milk, Spinach, Tofu, Whole grain cereal, Whole wheat bread are a few of the foods that are rich in magnesium.
