In a way I supose I approach diet the same way I approach religion. I study all the information I can and get as many varied views as possible. Then I formulate my own ideas and belifes, leaving my mind open and continually learning more.

I think blind faith in anything can be a problem. I'll even occasionaly argue with people who have the same ideas I do, just so they are forced to think about thier belifes. I've found the only people not willing to debate or discuss things are the people who are insecure about thier ideas.
