Here are my six reasons to include meat in your diet: It'shealthy. There are 29 lean cuts of beef, according to USDA standards. Beef provides nutrients like zinc, iron, protein and B vitamins, and half of the fat found in beefis monounsaturated, the same heart-healthy fats found in olive oil. Beef contains many other vitamins and minerals in lower amounts. Processed beefproducts, such as sausages, may contain particularly high amounts of sodium (salt). Bottom Line: Meat is an excellent source of various vitamins and minerals. These include vitamin B12, zinc, selenium, iron, niacin, and vitamin B6.
