Chromium is important in the metabolism of carbohydrates and fats. It works closely with the hormone insulin, facilitating the uptake of glucose into cells and the release of its energy. Thus both the regulation of glucose and the action of insulin are impaired by a dietary deficiency. Some studies have shown that supplements of a specific form of Chromium called chromium picolinate encourage the building of muscle. That makes it a hit with body builders.
However, other studies have found the chromium picolinate supplement to be ineffective. Although chromium is available in a variety of foods, food processing results in losses. A diet high in simple sugars also depletes chromium in the body.
Food Sources of Chromium are: Whole grains, nuts, broccoli, brewer’s yeast, wheat germ, fortified cereals, prunes, peanuts, peas.
Copper helps in the formation of red blood cells and assists in keeping bones, blood vessels, nerves, and immune system healthy. Studies indicate that copper deficiencies may be related to anemia, arthritis, heart disease, high cholesterol, heart irregularities, and high blood sugar. It is still under study for the role it may play in heart disease. Megadoses of vitamin C interfere with copper absorption.
Food Sources of Copper are: Whole grains, legumes, nuts, seeds, mushrooms, tomatoes, bananas, grapes, potatoes and dried fruit.
