(CBS) After almost two decades, the USDA food pyramid is history. First Lady Michelle Obama today unveiled the USDA's update on America's visual nutrition guide, replacing the familiar - and much maligned - pyramid with a plate.
The food pyramid has been around since 1992, but nutrition experts don't seem to be mourning its demise.
"It's going to be hard not to do better than the current pyramid, which basically conveys no useful information," Dr. Walter C. Willett, chairman of the nutrition department at the Harvard School of Public Health, told the New York Times.
The new design incorporates seven key dietary messages:
Experts argued the now-defunct pyramid lumped all types of foods in its design - including unhealthy ones at the top of the pyramid . That made it hard to tell which foods were better choices.
"The original icon was a bit misleading, e.g., all fats are bad," Dr. Sara Bleich, an assistant professor of public health at Johns Hopkins University, told ABC News.
USDA spent $2 million to design and promote the plate, the Times reported. Will this costly venture cause Americans to eat better?
Dr. Robert C. Post, deputy director of the USDA, told the Times that he hopes the new visual will prompt "consumers to say, 'I need to be a little more concerned about what I choose to build a healthy day's diet.' "
The USDA has more on the new food plate.
