It seems clear that thoughtful people are faced with nearly impossible choices on food. As I indicated, I think the organic/non-organic dichotomy is interesting, but far from the most important.
For me a more interesting idea is: “You are not what you eat; you are what you do with what you eat.", a notion Lustig at UCSF expands upon in video and text. [Here is a quick summary. Robert H. Lustig, MD, UCSF Professor of Pediatrics in the Division of Endocrinology]
I'm always telling myself: "It should be possible to eat great food cheaply." This chart suggests why I'm wrong.
