When buying, look for fewer than 10 grams of sugar and 2 grams of saturated fat, no trans fats, and at least 3 grams of fiber per bar. If you or your kids do have a bar once in a while (they are convenient!), eat it with milk and some fruit.

"Think of them as an occasional treat, not a meal replacement," says Elisa Zied, spokesperson for the American Dietetic Association. "They provide quick energy and some protein, but they can also have fat and sugar."
