Eat them: Atop a taco salad or mixed into fresh salsa.
Lentils: These legumes are a solid source of soluble fiber, which binds to bad cholesterol, helping to remove it from the body. Numerous studies show that such fiber is a powerful weight-loss aid that fills you up, curbs cravings and helps keep people from overeating. Also, a cup of lentils exceeds your required daily amount of folate— a B vitamin that might reduce the risk of breast cancer in some women.
Eat them: Cooked, as a side with grilled chicken or fish.
