Chromium is an essential trace mineral that helps to maintain healthy blood sugar levels. Chromium is not made by the body and must be obtained from the diet. It is thought that chromium plays a role in assisting insulin to allow glucose to enter cells and provide the cell with energy. Although studies are ongoing, some believe chromium has demonstrated the ability to improve cholesterol levels in the blood. Food sources of chromium include brewer’s yeast, beef, liver, eggs, chicken, oysters, wheat germ, green peppers, apples, banana, and spinach.
