the way we eat now

If you saw (or read about) Super Size Me -- here's an article that provides an informative overview of the evolutionary perspective on nutrition and the current rise in obesity in the United States. Good range of sources, and written in a fairly well-balanced way. (to my mind the political critique could be much stronger (i.e., how the current administration spoke out against the WHO's plan to combat obesity), but you can find more on that elsewhere)
