I caught on to the food pyramid scam in high school. I was at a friend's house when I mentioned that my niece was severely underweight and she needed to get healthier. My friend's dad went off about how "all you need to do is follow the food pyramid from the government and you'll be a healthy weight all your life." Even with my limited public-school education on government, I wondered "what does the government know about nutrition?" Years later I essentially figured out a proper diet for myself and it almost completely eliminates grains.

The food pyramid is a scam.
