The things you eat and drink are turned into energy．

You need energy for everything﹣playing，walking，running，thinking﹣even sleeping．

Feeling hungry may mean you are running low on energy．If it is not mealtime，you may need a snack to re﹣fuel．

But what sort of snack should you eat？This is like choosing the right fuel for a car．Some cars，such as racing cars，need the best fuel to go fast and keep their engines running smoothly．

So，if you want to be at your most lively，choose the best fuel．This means eating healthy snacks．There is no better way to keep your engine running smoothly!
