Recently I have received information and reviewed other information regarding new magnesium research. This body of research is so important I am making a special effort to communicate the information. Magnesium has been consistently depleted in our soils. It has been further depleted in plants by the use of potassium and phosphorus laden fertilizers which alter the plant's ability to uptake magnesium. Water from deep wells supplies additional magnesium not found in food, but surface water, our common source of supply, lacks magnesium.
Food processing removes magnesium.
Broiling, steaming and boiling remove magnesium into the water or drippings. High carbohydrate and high fat diets increase the need for magnesium as does physical and mental stress. Diuretic medications and insulin further deplete total body magnesium. As we age magnesium uptake may be impaired. Dieting reduces intake of already low levels of magnesium intake.
