Probing Question: Why did the USDA change its nutritional guidelines?

By Melissa Beattie-Moss - Research/Penn State First Lady Michelle Obama may be remembered for toppling a pyramid. A food pyramid, that is - the longstanding icon of the USDA's official nutritional recommendations for the American public. Since 1992, the food pyramid has been recognized - if not embraced - as the government's visual reminder about healthful eating practices. "The main criticism," said Terry Hartman , associate professor of nutrition at Penn State, "was that it was too complicated, and some perceived it as outdated." Taking its place as a teaching tool about nutrition? The less majestic (but perhaps more meaningful) symbol of a simple dinner plate. A panel headed by Michelle Obama, Agriculture Secretary Tom Vilsack and Surgeon General Regina M. Benjamin introduced the new MyPlate nutrition symbol in early June 2011 in Washington. Said Hartman, "MyPlate is meant to be a simple reminder to guide people to healthier choices. The USDA has set up a new website ChooseMyPlate.gov , with tools and resources to help consumers decide what to eat." Critics of the pyramid had long believed it difficult to understand at a quick glance, particularly since children are a primary audience.
