Trace minerals are only required in very small amounts, sometimes almost smaller than you can see with the naked eye. But this small quantity should not mean any less importance. A deficiency in any of them can be just as serious as any major mineral deficiency. Our government acknowledges twelve or thirteen minerals necessary for average health and that another eight or ten are possibly needed. One reason many have been overlooked is that they just aren't available from the soils that produce our foods.
Soils provide the minerals necessary for plant development.
Plants serve as food for the animals which assimilate them. Then, we eat the meat. At least 84 minerals have been isolated from human tissues and at least 60 are known to function in metabolic reactions. What is happening today, is an awakening as to the importance of minerals in total health. They are actually the foundation of our biochemical life.
