#3 Vitamins Cure AIDS
Vitamins are good for you, but it's not like they can cure AIDS. If you agree with that statement, you could be sued for one and a half million dollars. That's what journalist Ben Goldacre discovered when he called attention to some slightly dodgy behavior by Matthias Rath. Here "slightly dodgy" is defined as "putting out full page ads in South Africa, claiming that AIDS medicines are useless but vitamin pills will cure you, where tens of thousands of people die every month from AIDS".
