“but where do you get your protein?”
Most of us grow up believing we need meat, eggs and dairy in order to get adequate protein, or that somehow there is a serious risk that we will starve without enough of it. When I was first trying to become a vegan, those questions really troubled me. Where was I getting my protein? Was I getting enough? Was I going to wither away from malnutrition? It is helpful to understand just a few basics about nutrition to put our own doubts to rest.
Protein is a combination of amino acids. There are 20 standard amino acids, and we need all of them to perform a range of important functions in our bodies, from metabolism to replicating DNA to muscle development. Plants have the ability to produce all of these on their own, but animals like us can only manufacture about 11 on our own. We need to obtain the other nine through food. The amino acids we must obtain through food are called “essential” amino acids.
These can be obtained from animals or from plants. Most animal flesh is similar to our own flesh and contains all nine essential amino acids in the proportions that we need. Most plants also contain all of the amino acids, but often are low in one or more of them, so rather than relying on one food source for all of our protein needs, we need to obtain our protein from a range of foods.
