Whether you're following a vegan diet or just trying to cut down on animal foods, pea protein will help you meet your protein needs. It's no longer just about split pea soup, though. The benefits of pea protein may play a growing role in the U.S. food market.

High-Quality Protein Source

In an animal study published in "Agro FOOD Industry Hi Tech" in 2012, researchers found that the protein quality of one pea product was similar to that of eggs and soy, which are considered complete sources. Complete protein sources supply all of the amino acids that your body cannot make. Many plant proteins only provide a few of these amino acids.


Pea protein is a good source of arginine, an amino acid your body needs to build muscle. Arginine is conditionally essential, meaning that you need more of it in times of stress or illness. You'll get more arginine from pea protein than from other protein sources, according to an article on the FoodNavigator-USA website.

Food Allergy Alternative

If you avoid baked goods and pasta because you're allergic to eggs, pea protein may be the solution. According to the Northern Pulse Growers Association, pea concentrates and isolates can replace eggs in cupcakes, cookies, waffles and ravioli while maintaining flavor and texture. You may also enjoy pea products as a protein source if you have a milk or soy allergy.
