We can’t look at a pyramid these days without thinking of food and healthy eating. There was the U.S. government’s Food Guide Pyramid, followed by its replacement, My Pyramid, which was basically the same thing, just pitched on its side. The problem was that these efforts, while generally well intentioned, have been quite flawed at actually showing people what makes up a healthy diet. Why? Their recommendations have often been based on out-of-date science and influenced by people with business interests in their messages.
