What are proteins from animal sources?

Any of your meats will contain protein. You can also find protein in egg whites, peanuts, peanut butter, jerky, and pork rinds.

Proteins are made up of chains of amino acids. All unrefined food has protein.

One-half cup of beans contains as much protein as an ounce of broiled steak. Plus, these nutritious nuggets are loaded with fiber to keep you feeling full for hours. Fifty grams of soy protein daily can help lower cholesterol about 3%. Eating soy protein instead of sources of protein higher in fat -- along with a healthy diet -- can be heart healthy.
