It is called an “essential trace element” because very small amounts of zinc are necessary for human health.
Zinc is found in pumpkin seeds, sunflower seeds, seafood, whole grains, soybeans, and onions. Zinc is very much associated with protein foods. Thus, you may assume that most foods high in zinc are protein-rich as well. The best sources of zinc include beef, lamb, pork, crabmeat, turkey, chicken, lobster, clams and salmon. If you are a vegetarian, you will most probably intake less zinc that those who have meat-based diets. Good zinc food sources aside from meats are dairy products such as milk and cheese, yeast, peanuts, beans, and wholegrain cereals, brown rice, whole wheat bread, potato and yogurt. Of all these vegetarian zinc foods, pumpkin seeds offer one of the most concentrated non-meat food sources of zinc.<br>
*Oysters: Depending on type and variety oysters provide 16-182mg of zinc per 100g serving. This accounts for 110%-1200% of the RDA for zinc. The food highest in zinc is The Steamed Wild Eastern Oyster which provides 182 mg of zinc per 100g serving, or 76mg (509% RDA) in 6 oysters, and 154mg (1029% RDA) in a 3 ounce serving.
* Peanuts : Peanuts are a great source of zinc, 100 grams of oil roasted peanuts will provide 6.6mg (44% RDA) of zinc, or 8.8mg (59% RDA) in 1 cup chopped, 1.9mg (12% RDA) per oz (~39 peanuts). Dry roasted peanuts will provide half as much zinc at 3.3mg (22% RDA) per 100 gram serving, or 4.8mg (32% RDA) per cup, and 1mg (6% RDA) per oz.
==Special Precautions of Zinc==
*Zinc is LIKELY SAFE for most adults when applied to the skin, or when taken by mouth in amounts not larger than 40 mg per day. Routine zinc supplementation is not recommended without the advice of a healthcare professional. In some people, zinc might cause nausea, vomiting, diarrhea, metallic taste, kidney and stomach damage, and other side effects. Using zinc on broken skin may cause burning, stinging, itching, and tingling. *Taking high amounts of zinc is LIKELY UNSAFE. High doses above the recommended amounts might cause fever, coughing, stomach pain, fatigue, and many other problems. *Taking more than 100 mg of supplemental zinc daily or taking supplemental zinc for 10 or more years doubles the risk of developing prostate cancer. There is also concern that taking large amounts of a multivitamin plus a separate zinc supplement increases the chance of dying from prostate cancer. *Taking 450 mg or more of zinc daily can cause problems with blood iron. Single doses of 10-30 grams of zinc can be fatal. *Zinc nose sprays (Zicam, Cold-Eeze) are POSSIBLY UNSAFE. These products may cause loss of ability to smell. In June 2009, the US Food and Drug Administration (FDA) advised consumers not to use certain zinc-containing nose sprays (Zicam) after receiving over 100 reports of loss of smell. The maker of these zinc-containing nose sprays has also received several hundred reports of loss of smell from people who had used the products. Avoid using zinc nose sprays.Special Precautions & Warnings:*Pregnancy and breast-feeding: Zinc is LIKELY SAFE for most pregnant and breast-feeding women when used in the recommended daily amounts (RDA). Pregnant women over 18 should not take more than 40 mg of zinc per day; pregnant women age 14 to 18 should not take more than 34 mg per day. Breast-feeding women over 18 should not take more than 40 mg of zinc per day; breast-feeding women age 14 to 18 should not take more than 34 mg per day. *HIV (human immunodeficiency virus)/AIDS: Do not take zinc if you have HIV/AIDS. Zinc might shorten your life.*Note that many zinc products also contain another metal called cadmium. This is because zinc and cadmium are chemically similar and often occur together in nature. Exposure to high levels of cadmium over a long time can lead to kidney failure. The concentration of cadmium in zinc-containing supplements can vary as much as 37-fold. Look for zinc-gluconate products. Zinc gluconate consistently contains the lowest cadmium levels.* Antibiotics (Quinolone antibiotics) interacts with ZINC* Cisplatin (Platinol-AQ) interacts with ZINC* Penicillamine interacts with ZINC
==The benefits of Zinc are==
Zinc is the second most important trace mineral in the body, surpassed only by iron. It plays an important role in immune function, wound healing, blood clotting, reproduction, growth and smell. Zinc deficiency is characterized by poor wound healing, loss of appetite, weight loss and white marks on the fingernails.
* Reducing diarrhea in malnourished children, or in children who have low zinc levels. Severe zinc deficiency in children is common in developing countries.
*Treating Wilson’s disease, a rare genetic disorder.
*prostate cancer. This mineral is necessary for the formation of RNA and DNA and a healthy immune system. And, you guessed it: a healthy immune system is better able to kill cancer cells. Zinc is vital for prostate health and for male hormone activity. You need zinc to produce sperm and semen. There's more zinc in your prostate gland than any other part of your body.
*Zinc supplementation or dietary intake (from milk, for instance) can help reduce feelings of anger, hostility, and depression
