Waashington ? There’s a new U.S. symbol for healthful eating: The Agriculture Department unveiled “My Plate” on Thursday, abandoning the food pyramid that had guided many Americans but merely confused others.

The new guide is divided into four slightly different-sized quadrants, with fruits and vegetables taking up half the space and grains and protein making up the other half. The vegetables and grains portions are the largest of the four.

Gone are the old pyramid’s references to sugars, fats or oils. What was once a category called “meat and beans” is now simply “proteins,” making way for seafood and vegetarian options like tofu. Next to the plate is a blue circle for dairy, which could be a glass of milk or a food such as cheese or yogurt.

Some critics, including congressional Republicans, have charged the Obama administration of reaching too far in trying to make Americans eat healthier, especially when it comes to new rules that tell schools what children can eat on campus.

The new plate is simply guidance for those looking to improve their diet, however. It’s supposed to be a suggestion, not a direction, said Agriculture Secretary Tom Vilsack.

“We are not telling people what to eat; we are giving them a guide,” he said. “We’re not suggesting they should not have a cookie or dessert; that’s not what it’s about.”

Vilsack said the new round chart shows that nutrition doesn’t have to be complicated. After almost 20 years of leaders preaching good eating through a food pyramid the department now says was overly complex, obesity rates have skyrocketed. He showed off the new plate with first lady Michelle Obama, who has made healthful diets for children a priority through her “Let’s Move” campaign.

“Parents don’t have the time to measure out exactly three ounces of protein,” Obama said as she introduced the new graphic. “We do have time to look at our kids’ plates.”

The department is planning to use social media — posting advice every day on Twitter, for example. The address of the accompanying website, choosemyplate.gov, is written on the chart. That website will eventually feature interactive tools that help people manage their weight and track their exercise.

The new chart is designed to be “more artistic and attractive” and to serve as a visual cue for diners, said Robert Post of the Agriculture Department’s Center for Nutrition Policy and Promotion. He has spent two years developing the plate and the website.

Though the plate is divided into four different-sized sections, the servings don’t have to be proportional, Post says. Every person has different nutritional needs, based on age, health and other factors.

The graphic is based on new department dietary guidelines released in January. Those guidelines, which are revised every five years, tell people to drastically reduce salt and continue limiting saturated fats.
