Do you eat crab legs? Crab is an excellent source of zinc - a powerful antioxidant mineral that supports a healthy immune system and is involved in DNA synthesis.

In a recent study published in Epidemiology, a lack of zinc combined with an excess of copper and a deficiency in magnesium increased the risk for both heart disease and cancer.

If you're not keen on crab, there are plenty of other excellent sources of zinc. Oysters, clams, and lobster are high on the list, as are grass-fed beef, nuts, peanut butter, beans, lentils, and yogurt.
