It is important for us to keep in good health . I will give you some advice about how to be healthy. First, you have to stop eating fast food.Second，you should do more exercise.Third， remember to have breakfast every day.To keep healthy,we should have balanced diet.
As for me, I always do exercise at least an hour every day. I go home on foot after school. And I often do gymnastics in my free time. I do not have fast food,either. I eat more vegetables and fruits bacause they are good for our health.

第一段第二句，illness变成复数illnesses；“also should”不删掉会没有谓语吧？再把后面的by改成through；reasonable food改成balanced diet。
第二段，am是多余的，删掉！（every day分开来用表达“每天都”，你把它和everyday区分得很好。）第二段最后一单词，用health！
应该还有可以修改的地方。加油孩纸。我高一。

also should 最好去掉
I am always 的am去掉
vegetable加s
our healthy改成our health

eat vegetable要加s，蔬菜可数。
