What are some sources of protein aside from meat?
I want to start a vegetarian life, but I don’t want to change the amount of protein intake I used to consume. In other words, I want to learn how to compensate the protein I’ve been consuming from meat with vegetarian options.
While there is an exhaustive list of alternate sources of protein already mentioned, it’s important to note that on their own they don’t provide all the essential amino acids together.
There are two sources of complete proteins: tofu (from soy) and whole grains such as quinoa. By combining legumes, whole grains, and/or nuts with each other, you can still get your complete proteins. For instance, a whole wheat tortilla filled with beans and brown rice would supply a complete protein. On their own, beans would not supply you with all the essential amino acids your body requires.
