But all the information is already out there, anyone who can read has access to it.  It's not like we don't know simple carbs, sugar/high-fructose corn syrup, deep-fried everything is making some people fat and unhealthy.  You can look up a reasonably satisfying, healthy diet for the coming week in about 10 mins, and it doesn't need to be expensive either...I spend about $40 a week on food, and I could trim that down a bit too. Sometimes scare campaigns can do some good. I think that was OP's point.  Here in Canada we also have the cigarette packs with scary pictures/facts on them, and I know a lot of people who quit smoking after those came out.
