Mark Bittman makes a couple of good points here: food labeled “organic” is not necessarily true to the spirit of organic food (i.e., is sustainable, treats animals and the land well, etc.); and you don’t necessarily have to buy “organic” food to eat better. An easier place to start is simply with eating real food instead of processed food, eating more fruits and vegetables, etc. This is largely the lesson of Michael Pollan’s books, too, and both Pollan in The Omnivore’s Dilemma and Singer and Mason in The Ethics of What We Eat spend time examining the image and the reality of “big organic” producers.
