That article doesn't sound like it came from a legitimate medical facility or journal or research report. It sounds like some kind of TV infomercial. I don't see anything wrong with leading a healthful lifestyle but I don't believe that means denying yourself those things all the time. Everything in moderation is fine, and those of us who have medical conditions which require limiting certain food products (like carbs for diabetics) will do what we have to do, but articles like that do more harm than good.
