Students' Answer to the Task "Is fod in Japan healthy?"

The following is a student's answer to the task, "Is food in Japan healthy?"

I think that food in Japan is healthy.  It is because Japanese food uses fish, vegetables and meat.  So Japanese who eat them live for a long life.  I often eat Japanese food.  So I have not been sick for five years.  I eat a lot of vegetables every day.  Especially, I often eat tomatoes, because they have a lot of lycopene.  So it is very good.
