My children, just like everyone else's, should be eating more fruits and vegetables. and drinking more water. We have a hard time getting in the recommended 5 fruits and veggies and 8 glasses of water. Healthy eating and active living go hand in hand. Sometimes all it takes is a healthy, energy packed snack to avoid the afternoon meltdown. (Mine and theirs.)
Fresh fruits and veggies are particularly power packed. Let them snack on fresh grapes while watching TV or doing homework. You also cannot underestimate the value of drinking plain water. You fight off dehydration without all the sugar. And let's face it, they get plenty of sugar during the day.
Our family rule is when the kids get home from school, the first thing they eat must be a fresh fruit or veggie and the first thing they drink must be water. They're pretty hungry at this point so they'd probably eat about anything. Sure, they slather those baby carrots in ranch dressing, but at least their getting in one serving a day.
My friend's new book Kabobs for Kids has some great ideas for making fresh stuff fun. It also has some treats in there, but hey, everyone deserves a treat now and again. Balance the sugar with extra time outside some days.
