I’m less than halfway through this book, but it is amazing. If you live in USA, and are at all interested in where your food comes from, you simply must read The Omnivore’s Dilemma. For me the most revealing has been the expose of corn. I mean, I knew that America had a surplus of corn, and I understood, vaguely, that it had something to do with subsidies, but I now really understand how we got into the situation we’re in. What I didn’t realize at all before was just how much nitrogen-based fertilizer goes into growing corn, and just how much energy is needed to make the fertilizer. It makes the idea of biofuels look laughable (for every calorie that comes from a corn kernel more than two calories of energy, mainly in the form of fossil fuels, go in). I’m not really sure how one moves away from a corn-based diet – being vegetarian would certainly help, and buying food in it’s rawest possible state has to help – you have a better grasp on what you have. Beyond that, I think you just has to ask a lot of questions about where you food has come from, and what’s gone into it.
