Anyone knows a healthy diet for a 16-year old? What foods should I eat and which not to eat?

Question

I don't want to loose weight, just feel better, get more energy, be able to concentrate better in school.

Answer 1

Eat lots of fruit and veges! To help concentrate better in school try eatting an apple before the class that you really want to concentrate on. Drinking water before you learn somethings helps you remember it better. (Teacher told me that in middle school). And I fell that I have more energy when I treat myself to a little specail snack after a job well done on a test.
