Over half of the less than two ounces of magnesium in a 130- pound person is in the bones. Magnesium is critical to the operation of hundreds of enzymes and directly affects the metabolism of potassium, calcium, and vitamin D. It plays an integral role in nearly three hundred body functions. It aids in bone growth, basic metabolic functions, and the functioning of nerves and muscles, including the regulation of normal heart rhythm. Low intake has been linked to high blood pressure, heart-rhythm abnormalities, and heart attack.
The food sources of Magnesium are mainly Nuts, legumes, whole grains, wheat bran, dark green vegetables, bananas, apricots, etc.
People whose drinking water has a high magnesium content experience a lower incidence of sudden death from heart attack. Magnesium is easily washed and peeled away from foods during processing, so fresh or slightly processed foods are your best choices.
