Food pyramid bullshit was one of those things that just seemed so retarded on its face even as a kid. But I never went so far as to connect that feeling towards understanding that fat isn't evil and that composing a diet of tons of carbs is actively harmful to one's body until the past year or so.

Out of all the rabbit holes to go down, I can't recommend it enough because you'll come out the other end feeling better physically and mentally than ever before.
