Healthy food is good for your health. We should eat healthy food. Healthy food, including vegetables, fruits, fish, meat, and so on. But we should keep an adequate diet, and we cannot not eat certain foods too much.

We know that some of our students do not like eating lunch at school because the food is not delicious. So they often go out of school to buy something they like to eat. But I am afraid it is bad for their health to eat lunch outside because some of the food they buy isn't healthy enough.

Translation:

Healthy food is good for our health and we should eat it Some healthy foods include vegetables, water, fish, meat, etc. We need to eat reasonably and can’t drink too much of certain foods

We know that many students like to eat school lunches because they are delicious, so they often buy some outside the school. If you like to eat, I’m afraid that buying some off-campus food is harmful to your health.
