Zinc is used in the body for production of new cells as well as optimum functioning of the immune system. Zinc deficiency may cause lack of alertness, hair loss and loss of taste. If your levels are low then it can be rectified by eating zinc supplements (as advised by your physician) or even by adding zinc containing foods in your diet (meat/poultry, beans, nuts, crab, lobster, whole grains, breakfast cereals, and dairy products. etc.).
