•Drink water and milk most often.When you’re really thirsty，cold water is the No.1 thirst­quencher.And there’s a reason your school cafeteria offers cartons of milk.Kids need calcium to grow strong bones，and milk is a great source of this mineral.How much do kids need？About 800 milligrams each day if you’re 6 to 8 and 1,300 milligrams if you’re 9 or older.But try to limit sugary drinks，like sodas，juice cocktails，and fruit punches.They contain a lot of added sugar.Sugar just adds calories，not important nutrients.

　　•Limit screen time.What’s screen time？It’s the amount of time you spend watching TV，DVDs，and videos，playing handheld computer games，and using the computer.The more time you spend on these sitting­down activities，the less time available for active stuff，like basketball，bike riding，and swimming.Try to spend no more than 2 hours a day on screen time.

　　•Be active.Find ways to be active every day.Not everyone loves baseball or soccer.Maybe your passion is karate，or kicking ball，or dancing.Ask your parents to help you do your favorite activities regularly.You might even write down a list of fun stuff to do，so you can refer to it when your mom or dad says it’s time to stop watching TV or playing computer games!

　　.

　　A．satisfy all kinds of needsB．get enough vegetables
