Selenium deficiency and chromium deficiency are two of the most common mineral deficiencies in the United States.
The reason people don't get enough of these two nutrients is because the chemicals they spray on the crops to control pests and weeds bind to chromium and selenium and render them bioUNavailable. The topsoil has been contaminated and essential minerals have been depleted.
Evidence of Selenium deficiency is the high rate of cancer and Arthritis in this country. Evidence of Chromium deficiency is the high rate of diabetes.
