Ehret is one the great past experts, he didn't live long, but he didn't care about paraites, etc. BUT, he never suggested that meat was a human food, so don't see your point????
If you find a MD past or present that suggest you need meat, then you had better look the book over pretty good and if you accept it, then PITCH your Ehret books because the 2 will never agree on health.
People either know, or they don't know! You are cold or you are hot, you can't be warm and agree with both.
