If people don't eat properly, they (4)_will get__ ill.It's that simple.If you eat lots of fruit ad salad and beans, you (5)_will__ get all the things you need to say healthy.But you're only 14years old. If you (6)__live_ at home with your parents and you probably do -you'll have to ask them what they think too. If your mum cooks for you , (7) it _will_ be difficult for her to make you special meals. If I were you, I (8)_would__ think about this carefully and maybe wait until you're a bit older before making such a big decision.
