ATLANTA (AP/WAOK)- McDonald’s says it will start posting calorie counts on menus in restaurants across the country next week, ahead of a new regulation that will require the information.

The world’s largest hamburger chain plans to announce the move Wednesday morning. It’s making the change as it tests healthier menu items.

For example, McDonald’s Corp. says it’s testing an Egg McMuffin that’s made with egg whites and a whole grain muffin.

It’s also testing versions of the McWrap, which are already sold in Europe and clock in at less than 350 calories. And the chain says it will offer more seasonal fruits and vegetables through its limited-time offers.

President Obama’s health care overhaul will require chains with 20 or more locations to post calorie counts as early as next year.
