A healthy eating habit along with enough exercise can help you keep healthy. When you are young, it is important to give your body what it needs. If you skip meals, you can't get enough calories(卡路里). And then you may feel tired. By the way, the calorie is just another word for energy(能量). About 50% of your calories should come from rice, bread, vegetables and fruit. You also need to drink a lot of water, six to eight glasses a day. Drinking enough water can make your body work better and make you healthier.
Exercise can help to make you look good, feel good and be healthy. Scientists say that kids should spend at least thirty minutes exercising a day, five times a week. It is easy to do! You can walk or ride your bike to school, and play sports at school. However, many kids often give up (放弃)sports and say that they have no time left after finishing their homework. In fact, doing exercise can help them sleep better and do better in their lessons.
If you follow the advice above, you will look and feel much better and become healthier.
