More than a dozen restaurant chains are working to make children's meals more healthy through the Kids Live Well initiative.

The National Restaurant Association developed the voluntary program that restaurants can opt to take part in.

Burger King, Cracker Barrel, Chili's and IHOP are among the 19 restaurant chains that have joined.

"These Kids Live Well items emphasize health ingredients such as fruits, vegetables, lean protein, whole grains and lowfat dairy items," said Anita Jones-Mueller, president of Healthy Dining. "These choices also meet nutritional criteria and... dietary guidelines."

To be considered part of the initiative, each meal must include an entire side dish and beverage containing only 600 calories or less.

Participating restaurants also have to display and promote healthier menu options and offer at least one individual item with 200 calories or less that limits fats, sugars and sodium.
