Animal Protein

----------

Animal-based protein sources all contain all of the essential amino acids in sufficient amounts. 

These include meat, poultry, seafood, dairy products and eggs. While these protein sources make it simple for you to get all of the essential amino acids, they are also sources of fat, saturated fat and cholesterol, which should be limited in your diet.

Plant-based Protein

-----------------

Plant-based protein sources, except for quinoa and soy products, do not contain all of the essential amino acids. However, if you eat a variety of these foods over the course of the day, you should get sufficient amounts of the essential amino acids. 

Combinations of plant-based protein foods that provide all the essential amino acids include whole grains and beans, seeds and beans and seeds and grains. 

As long as you eat one of these combinations -- either together or separately -- during the same day, you will get sufficient amounts of amino acids.

 Eating some animal-based protein during the day along with plant-based protein also provides sufficient amounts of all essential amino acids.
