The 7 classes of food....it is a revision but do you really have a balanced diet?

WE studied the 7 classes of food while in school. I can still remember. In our country, our students study them while they are in form two. Are they to be studied for the sake of studying?

What are they?

Have we forgotten them?

"Nothing needs to be too much, but we must not miss out anything!" Keep a balanced diet! It works miracles!

Don't tell me that our car only needs petroleum and dont need the brake oil or any water!!!

Have a look at what you are eating! Don't eat for the sake of eating!
