Back in the 90s I noticed that all the Fast Food chains started to change their french fries. They seemed to go to this new, tasteless, batter coated version of their former fries. Most noticeably to me, Burger King then Wendys. I could not understand the reason and suspected it had something to do with trying to make them healthier. Well, as Malcolm Gladwell points out in his podcast, it all came about from one man’s misguided crusade. The worst thing about it, is now that some of the ideas behind the change have been debunked, no one seems to be in a rush to bring back the tastier version.
