Hum interesting but what about those who have a fast oxydizing metabolism like myself who need at least 60 to 80% of protein on my plate to function properly. Or why is it that if you give vegetables or anything less than meat or even raw meat to an Eskimo he will immediately fell and be sick ? I have learned that everybody has its own biochemical individuality and metabolism not everybody can be vegan. Studies show that its important to eat like our ancestors did. It is also proven that a plants suffer like humans and animals wen cut or pressed or cooked.
