It also depends on what foods and drugs we're talking about. Lobbyists and spin doctors have been misleading the public for a long time on the benefits of certain foods and drugs while demonizing others. Especially when you really start to look into what predominate companies hold or have held a monopoly over certain goods and pharmaceuticals. It's disgusting, because the stance only changes, once the side making the most money changes or once a company/ies are set to make a lot of money by making a change.
