Magnesium is an essential mineral for human nutrition. Magnesium in the body serves several important metabolic functions. It plays a role in the production and transport of energy. It is also important for the contraction and relaxation of muscles. Magnesium is involved in the synthesis of protein, and it assists in the functioning of certain enzymes in the body.
Green vegetables such as spinach are good sources of magnesium because the center of the chlorophyll molecule (which gives green vegetables their color) contains magnesium. Some beans, peas, nuts, seeds, and whole, unrefined grains are also good sources of magnesium. Some food rich in magnesium are broccoli.
