As kids head back to school this month, health experts are stressing that healthy eating leads to better performance in the classroom. Snacking between meals isn’t a bad thing, according to Norton Children’s Prevention and Wellness’ Nikki Boyd. It can aid learning by keeping bellies full in the classroom given the wide ranger school lunch times. Boyd says the issue is what those snacks should be.  Boyd says having ready-to-go snacks of carrots, sliced apples or grapes, make it easier and convenient to snack the healthy way. She recommends letting children help pick snacks and for parents to be a role model by snacking healthy themselves. Norton Children’s is using a grant from Kohl’s Cares to promote kids health.
