The best Subway option: a kids roast beef sub, apple slices and 1% milk, which comes in at 395 calories.
Other healthy choices: Burger King's oatmeal, IHOP's whole wheat blueberry pancakes, Outback Steakhouse's kids sirloin with apples and grapes, and Olive Garden's cheese ravioli with broccoli and orange juice.
"Four years ago we found that only 1% of kids meals at the top chain restaurants were healthy, and now 3% are healthy," Wootan said. "So there is a tiny bit of improvement, but it's very, very small."
Sodium rates also have shown improvement, she said. In 2008, only 15% of restaurant meals met the sodium standard; now 35% do.
The bottom line, she said: There's a lot of work to do.
"In order for parents to feed their children healthfully, restaurants need to help," Wootan said. The group encourages participation in the Kids LiveWell program, and says restaurants should offer more whole grains and get rid of soda and other sugary drinks.
"We know they can do it, because some are already doing it," she said.
