Need a good excuse to indulge in decadent crab legs? How about warding off cancer and heart disease? 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.
Is That a Corn Burger You’re Eating?
In Michael Pollan’s brilliant book, The Ominivore’s Dilemma, he uncovers an important kernel of truth about conventional beef. It’s 60% corn!
Feedlot beef is much different from grass-fed beef. It’s vastly lower in key nutrients (like beta-carotene), higher in calories and inflammatory omega-6 fat and all but completely lacking an important, cancer-fighting, tummy trimming substance called CLA.
