<p>beans and soy are incomplete proteins… meats will always be the best protein source as it has certain amino acids that nothing else really has except maybe milk. Not all protein is equal. And I really doubt that the average american eats too much protein. I’ve read some stuff on that and the numbers are pretty low. Fibre is really only necessary for your crap and to prevent blood sugar spike and if you’re avoiding sugar that shouldn’t be a problem anyway.</p>
