As we all know, we are what we eat. Bad eating habits are very common among us students. Some of us often go to school without eating breakfast. And some like to have too many snacks and are particular about food. In the long run, our health will be worse and worse. To keep fit, we should eat healthy food. We'd better have meals regularly. We also need proper exercise. In my opinion, we should try to develop healthy eating habits to build up a strong body. In this way, we can have enough energy to study better.
