Common examples of the limiting amino acids in plant-based proteins include lysine, methionine, isoleucine, threonine and tryptophan. Of these, lysine appears to be to be most commonly absent, particularly from cereal grains .
Do vegans get all the amino acids?
Vegans can get protein from nuts, peanut butter, seeds, grains, and legumes. Non-animal products like tofu and soymilk also provide protein. Vegans have to consider getting enough “complete proteins.” A complete protein contains all the amino acids your body needs to help maintain your metabolism.
