Food
Healthy Diet
R&A Read the passage and answer this question: What food do we need?
How's their diet? Healthy or not?
I am Bill. Hamburgers are my favourite food. So I always go to McDonald's and eat hamburgers with my friends. Sometimes I have some French fries. They're yummy. But I seldom eat vegetables. I don't like them at all.

I am Sally. I love vegetables and fruits very much. They are healthy. So I always eat tomatoes. Sometimes I have some apples. They are my favourite food. But I don't like meat. I seldom eat it. I am afraid of fat.

Food is very important. It makes us strong and healthy. We need apples, tomatoes and cabbage. They give us vitamins. We need fish, pork and eggs. They give us protein. We need rice, bread and noodles. They give us starch. Some of us enjoy sweet food, but we do not need too much of it.
We should keep a balanced diet!

We should eat less sweet food.
We should eat less chicken, fish and cheese.
We should eat more apples, oranges and carrots.
We should eat more bread, rice and noodles.
