【简答题】
Almost every day, we discuss the topic of health, especially for kids. But w hat is health? “Health” means eating well, getting enough exercise, and having a healthy weight. Here is some advice on healthy eating. They can help you stay healthy. Eat a variety of foods, especially fruits and vegetables. We all know that eating fr uits and vegetables can help us stay healthy, but many of us only eat our favorite foods. Remember that we can only get the nutrition we need by eating different kinds of food, especially fruits and vegetables. 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 olde r. You should also try to have less sugary drinks, like soda and coca. They include a lot of added sugar. Sugar just adds calories, not important nutrition. Listen to your body. When you are eating, notice how your body feels. When your stomach fe els comfortably full, stop eating. Eating too much makes you feel uncomfortable. If you do it too often, it can make you unhealthy and fat. Limit screen time. What's screen time? It's the amount of time you spend watching TV, movies, and playing co mputer games. The more time you spend on these sitting - down activities, the less time you spend playing sports, like - basketball, and some other activities like bike riding and swimming. Try to spend no more than 2 hours a day on screen time. (273 words)
