As a student, I know I need a healthy body and mind. With the development of science, there are many kinds of food. But most of them are junk food. Typical meals include rice, dumplings, meat and vegetables. In my opinion, we should eat more green vegetables and a little meat. Too much meat contains too much fat whichis bad for health. I think three meals must be eaten on time. I'll eat healthy food and take exercise every day. I hope you all follow me and we'll keep healthy.作为一个学生,我知道我需要一个健康的身体和心灵。随着科学的发展,有许多食物种类。但他们中的大多数都是垃圾食品。典型的食物包括大米,饺子,肉和蔬菜。在我看来,我们应该多吃绿色蔬菜和少量的肉。太多的肉类含有太多的脂肪,对健康有害。我认为必须吃三餐时间。我要吃健康的食物和锻炼的每一天。我希望你们都跟着我,我们要保持健康。
