Very interesting. I'm not going to draw a conclusion yet but that is certainly reason to doubt his conclusions about that scary scary protein. Also perhaps it explans why people lose weight on nearly no protein diets and also why they are so obsessed with "detoxification", I kind of suspected that
One thing to note is that Campbell tends to recommend 10% dietary protein as the optimal amount so perhaps he realizes that 5% is indeed deficient and troublesome.
Most scientists, philosophers, psychologists etc are in love with their hypothesis and will pull out every stop and use every ploy they can to prove it. Usually this is a good thing because every side of the story should be told with the utmost passion and competency, but some of this is seemingly a blatant obfuscation. I would like to see a response.
