Healthy Eating
Healthy eating is important to us. What and how should we eat to be healthy?
First, we must have enough food, never too much or too little. The food must be clean and we should cook it properly.
Second, it’s very important for us to keep a balanced diet. Different kinds of foods are necessary, such as rice, bread, meat, fish, eggs, milk and vegetables. Rice and bread give us energy. Meat, fish, eggs and milk help our bones grow. Fruit and vegetables make us healthy.
Third, we should eat regularly. It’s said that half of the students don’t have a regular breakfast or don’t eat anything at all in the morning. It is bad for their health. In fact, a good breakfast keeps us strong.
In short, we should not only eat enough food, healthy food but also eat regularly.

Healthy eating habit along with regular exercise is the only way to become fit. If you have the correct number of calories and exercise regularly, you will lose weight, keep fit, and feel great, too.
During your teenage years, it is important to give your body the energy it needs. If you skip (跳过) meals, you won’t get enough calories, and then you will feel tired. By the way, calorie is just another word for energy. About 50% of your calories should come from rice, bread, vegetables and fruit. You also need to drink a lot of water, 6 to 8 glasses a day. Water helps keep your system clean. Drinking enough water will make your skin better and make you healthy.
Exercise is something that can help to make you look good, feel good and be healthy. Experts suggest that teenagers spend at least 30 minutes exercising a day, five times a week. That is easy to do! You can walk or ride your bike to school, and do sports at school. However, teenagers often give up sports, saying they have no time left after their studies. In fact, doing exercise can help them sleep better at night and increase their ability to focus on their study.
If you follow the suggestions above, you will look and feel much better and become fit.
