Recent US based studies have shown that magnesium deficiency is quite rife; a 2006 National Health and Nutrition Examination Survey about half of the US population is Magnesium deficient.
According to Dr. Danine Fruge, Associate Medical Director, Pritikin longevity Centre, Miami, Florida, USA, Magnesium is responsible for about 300 chemical reactions in he body and affects the performance of the heart and the skeletal muscles. Exhaustion and muscle cramps/spasms are some symptoms of Magnesium deficiency. Other symptoms and signs include irregular heart beat, disorientation, nausea, vomitting and convulsions.
Diaagnosis of Magnesium deficiency is difficult as only about 1 percent is in the blood stream, most being in the muscles and tissues; it is therefore mainly by elimination.
Daily requirement of Magnesium is 400mg for men and 310mg for women. Sources are mainly plant foods such as green leafy vegetables, fruits, broccoli, nuts, whole grainsbeans and seeds. Animal sources though to less extent are milk and meat.
It is easy to have enoughmagnesium from our daily food but deficiency can happen if foods containing magnesium are not taken in enough quantity or if certain foods which affect the absorption or excretion of magnesiumare taken. Such foods include soda, caffeinated beverages and alcohol.
Take enough green leafy vegetable and fruits and moderate soda/caffeinated bevderages/alcohol to have enough Magnesium.
