     Almost every day, we discuss the topic of health, especially for kids. But what is health? "Health"

means eating well, getting enough exercise, and having a healthy weight. Let's read the following rules.

They can help you stay healthy.

1. Eat a variety of foods, especially fruit and vegetables. We all know that eating fruit and vegetables

can help us stay healthy, but many of us only eat our favorite foods. Remember that we can only get

the nutrition(营养) we need by eating different kinds of food, especially fruit and vegetables.

2. Drink water and milk most often. Everyone knows that water is important. Besides that, kids need

plenty of calcium(钙) to grow strong bones, and milk has  a  lot of it.  Every day, you should drink at

least three cups of milk(1300 milligrams of calcium), when you are  9  years  old or older. You should

also try to have less sugary drinks, like soda and cola. They include a lot of sugar. Sugar just includes

calories, not important nutrition.

3. Listen to your body. When you are eating, notice how your body feels. When  your  stomach feels

comfortably full, stop eating. Eating too much makes you feel uncomfortable. If  you  do it too often, it

can make you unhealthy and fat.

4. Limit(限制) screen time. What's  screen  time? It's  the  amount  of  time  you spend watching TV,

movies, and playing computer games. The  more  time you spend on these  sitting-down  activities, the

less time you spend  playing  sports, like  basketball,  and  doing  other  activities  like bike riding and

swimming. Try to spend no more than 2 hours a day on screen time.
