I get the raw thing, but how can nutritionists have such incredibly different views on what we should be eating?

On the one hand we have people like D. Graham who practically shun fat altogether, and, on the other hand, people like Aajonus Vonderplanitz who eat well over 50% fat (he claims to eat 1-2 sticks of raw butter per day, lots of raw meats, hardly any fruit, and never exercises).

This is like night and day. Is this Aajonus Vonderplanitz guy for real? Anyone tried his methods?

I just can't fathom how there could be such disparity of nutritional beliefs for humans.
