For plenty of parents, one definition of “family vacation” means relaxing the rules of mealtime: no cooking for mom and dad, and a few more treats, chicken nuggets, and child’s-meal toys for the kids.

If you feel guilty indulging your kids’ culinary druthers while on a family road trip, you have some reason to feel better. In the past few years, plenty of chain restaurants have made efforts to make kids' meals leaner and fresher, adding more fruit, veggies and non-fried options.  

A recent study, however, indicates that those kids’ meals still have a long way to go. The Center for Science in the Public Interest, with help from the University of North Carolina at Asheville, analyzed kids’ meals from 41 top chains, and found that the typical combo packs too much heft in terms of calories, salt and fat—sometimes even by adult standards. According to federal guidelines, the typical child between the ages of 4 and 13 needs 1,200 to 1,800 calories for the entire day. (Grown-ups need 1,600 to 2,400.)

Here are the five worst offenders we found at popular chains—some of which max out your child’s caloric quota for the entire day. The bright side: there are easy alternatives to make meals leaner, more nutritious, and even keep your child feeling full longer—so you can log in more miles before your next vacation stop.
