Since plant proteins (legumes, fruit, vegetables, nuts, seeds and grains) are incomplete proteins, vegans and vegetarians have to eat a variety of these daily to maintain balance. Plant proteins are called incomplete proteins because one or two of the essential amino acids is low. A lot of people are aware of this and combine beans and rice, or grains with nuts/seeds.
You don’t actually have to eat these combinations at one meal as once thought. As long as you eat complimentary plant proteins in one day, you’ve consumed complete proteins just like your carnivorous friends.
Protein has many important functions in our bodies such as protecting us from viruses and bacteria, and building and maintaining muscle. Make sure to get enough protein in your diet. Don’t overdo it though; the excess will be converted to fat.
