We never really think about it. If you are vegetarian (still eating dairy and eggs)...there is pretty much NO WAY you are not getting enough protein. Even if you are a vegan...it's highly unlikely that you would be deficient in protein.

What he is probably feeling is an after effect of the brainwashing of the dairy and meat industries...who pay LOADS of money convincing everyone in America that protein only comes from those two sources.

Protein is available in so many ways...beans, lentils, grains, greens, and more. Greens actually provide more usable protein oz. for oz. than meat does. Spirulina is a perfect example of that.

Bottom line, I'm sure he's getting enough. Even eating a lot of raw. However, the key...when eating raw, he does need to exercise to maintain total health.

There are some great videos/info out there...Google the terms "raw food and protein" and you will find a lot more...
