I think nutrition means to keep your body healthy and don't go high I am saying don't go high like don't eat too much sweet when you are at home or in a shop because some times in the shops you can see lots of sweet and some time you don't know what to do when you are in a shop all by yourself.
   the way you eat do you eat fast or slow because if you eat fast that is very bad for your heath so eat slow and eat right.
