Some years ago, I saw a tv documental that was almost identical to this text: McDonalds' fries, natural vs. artificial aromas, the New Jersey hub of fragance companies... I thought that this was a transcript of the show, except the tv version included interviews. Anyway, it doesn't seem conspiratory at all.
