There are also plant sources of proteins yo.
But they don't contain all the [essential] amino acids, hence why animal proteins are of higher quality.
Which is the protein we, as runners/bbs/pls/fitnessfreeakz, are interested in.
to plant proteins, except nuts, they're okay in my book. come on, you're supposed to be a cool kinesiology major. not a peta member jk xD
