Hi, dear boys and girls! Do you know how to be a healthy kid? Here are some rules you should follow.

First, eat different foods, especially fruit and vegetables. You may have your favorite food, but you'd better eat something different. If you eat different foods, you will probably get more nutrients（营养物质）your body needs

Second, drink water and milk as often as possible. When you're really thirsty, cold water is the No. 1 choice. Milk is a great drink that can give you more calcium（钙）your body needs to grow strong bones（骨头）.

Third, listen to your body. How do you feel when you are full? When you are eating, notice how your body feels and when your stomach feels comfortably（舒适地）full. Eating too much will not make you feel comfortable but make you fat.

Fourth, limit screen time. Screen time is the time you watch TV, DVDs and videos, or using computers. It is good to take more exercise, such as basketball, bike riding and swimming.

You can't watch TV for more than two hours a day.

Fifth, be active. One thing you'd like to do as a kid is to find out which activity you like best. Find ways to be active every day.

Follow these rules and you can be a healthy kid.

If you often feel tired and the doctor can’t find anything wrong with you, you may be in a state of subhealth (亚健康). Subhealth is a state between health and illness. Most of the subhealthy people are middle-aged ones who are usually stressed out because of work and family. And some of them are students who are having exams.

If you are subhealthy, it is not difficult for you to become well soon. You should have good living habits. For example, you should get up early and go to bed early. And you should exercise regularly. Exercising can keep you healthy. As for meals, it is better to eat less salt and sugar. Vegetables, fruit and fish are important for your body. You should eat more of them. It is not good to eat too much at one meal, because it may cause unhealthy changes in our stomach. And at last, a balanced diet (均衡的饮食) is very helpful in staying away from subhealth.
