Silicon is a common mineral required, along with calcium, for the development and maintenance of strong bones. Silicon also plays an important role in the formation of collagen and connective tissues, as well as the hair, skin and nails.
The relationship between silicon and heart disease is not clear at this point. Researchers know that silicon is required for maintaining flexible arteries, but they have also noticed that persons with atherosclerosis have high serum levels of this mineral. It is well known that silicon reduces the effect of aluminum, and that it plays a role in the onset of Alzheimer’s disease and osteoporosis.
Generally the American diet is abundant in silicon and deficiencies are extremely rare. Foods rich in silicon include whole grain breads and cereals, alfalfa, beets, bell peppers, beans, and peas.
