ZINC

Lowered levels of zinc can lead to poor blood glucose management, sugar cravings, loss of appetite, lousy digestion, poor resistance to infection, skin infections, lowered fertility, tissue repair, scarring and a wide range of other problems. Zinc rich foods include oysters, beef and lamb, pumpkin seeds, and sunflower seeds. You might also consider taking a good quality supplement if you know you are zinc deficient.
