Really? The only conservatives complaining that I recall were from changes to school lunches that resulted in a lot of food waste. It's been over 16 years so I'm more than willing to admit that was really the only part of the whole debacle that I remember.
The food pyramid wasn't really used in recent years by the US government, and changed to "MyPlate" in 2011, and if you actually read its guidelines nothing on there is terribly offensive.
