If one does not eat soy, (a primary form of protein) what other avenues are there to get the necessary amounts of protein. A person can eat only so many beans per day/week.
Hemp is an excellent source of protein. I like to make hemp protein smoothies for breakfast and/or for a post-workout snack.
Quinoa is high in protein.
Seitan (wheat meat) is very high in protein as well.
Sprouts have a good protein make up.
But most people in the US overestimate the amount of protein one needs. If you eat a balanced, varied diet, you shouldn't have to worry to much.
