Which are the foods with high protein?

Lots: Meat, peanut butter, lentils are some examples.

Lean proteins.: Focus on fish, pork, turkey, egg whites and protein - the real thing, not cold cuts or canned meats. And grill or bake or broil - no frying. If you don't eat meat, beans and soy are great but you need to learn how to combine them to make complete proteins for proper absorption.
