As Machiavelli in "The Prince" said "Keep your friends close and your enemies closer".  We cannot change the behavior of the multi-national food conglomerates by treating them as advisories.  They spend more money on marketing in a day then we spend on healthy eating in a year. What we can do is move them incrementally to providing and marketing healthier options.  Whereas the progress seems glacial, there is progress.  Kraft foods have developed healthy options. Salads are appearing in McDonalds and Berger King.  Subway is marketing healthier options and featuring a man who has lost a great deal of weight eating their products.  At the same time Western culture has begun to consider obesity a problem.  Food conglomerates will manufacture and sell what people will buy.  The two pronged process has to be to both educate them and education the public.
