Eat Less Red Meat

A large study conducted at Harvard has found that eating chicken or turkey instead of beef or lamb can cut women's heart disease risk. Researchers say this probably works for men too. Red meat contains baddies like heme iron and saturated fat, whereas these better sources of protein (ie poultry, nuts, fish and low-fat dairy) contain goodies such as fatty acids and polyunsaturated fats, which may protect against heart disease.
