Zinc molecules, like iron, are large and are therefore difficult to absorb. Most of the zinc in the body is found in the bones, but it is also found in the hair, skin and nails. The male prostate gland contains higher concentrations of zinc than any other organ, and zinc is believed to be essential to a healthy prostate. In addition, zinc therapy appears to help in the treatment of some prostate problems.

Zinc is essential for hormone metabolism and a strong immune system. A deficiency of zinc will prevent wounds, sprains, fractures and other injuries from healing rapidly. It is part of more than seventy different enzyme systems, and is necessary for the transport of vitamin A (stored in the liver) to the cells. It's also essential for the detoxification of chemicals, including alcohol. Low zinc levels may be a factor in toxemia (a pregnancy complication) and possibly contribute to low birth weight.

Zinc absorption is impaired by alcohol, diuretics, cortisone, Tagamet and antacids. Stress (physical or mental) causes zinc levels to drop rapidly. Zinc occurs naturally in foods, but it is destroyed in food processing. It is not a good idea to take zinc supplements without the advice of a professional, as excessive amounts can cause deficiencies of other minerals and very large amounts can have serious side effects.

Zinc is plentiful in foods but it is not easily absorbed, especially from foods such as whole grains, beans and lentils. The elderly and those following a low calorie or strictly vegetarian diet may be most at risk of deficiency. Infections, injuries and surgery cause excess loss of zinc in the urine. Excessive consumption of alcohol or refined sugar also depletes the body of zinc.

If your nutritional chart shows a possible zinc deficiency, iIncrease the amount of zinc-rich foods in your diet. Sea food, cold water fish, fresh meat, wheat germ, pumpkin and sunflower seeds, nuts, oats, brewer's yeast, eggs, tahini and mustard are good sources of zinc. Take a multivitamin/mineral tablet containing zinc. Cut back on alcohol and refined sugar if you consume them every day. If you have a high score take an extra 30mg of zinc in addition to the multi, for two months only. Don't take them at the same meal. Don't supplement with higher doses of zinc without asking your doctor.
