I recently watched the documentary "Cooked" on Netflix. In it, Michael Pollan makes some interesting observations about "real food" vs "industrial food", and the benefits of long cooking times, sourdough bread vs. yeast bread and so on. It echoes many of the same observations as this article.

That's not to say that he's 100% right about everything, but I think there is a very good point to be made that we ought to eat more home-cooked food, instead of fast food and processed food products optimized for production costs and shelf life.
