But is the new food pyramid really all that much better? The Harvard School of Public Health says no. Here is a short excerpt from the intro:
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.

Their recommendations have often been based on out-of-date science and influenced by people with business interests in their messages.
And here is the pyramid recommended by the Harvard folks:

For part of the Harvard critique, check out this press release from 2006. For another critique of the food pyramid, as well as some background history, check out this article here. One of the primary problems all along with the food pyramid is that the USDA is heavily influenced by business interests, so “health” isn’t always the top priority. Read up, and see what you think.
