Friends, here is an excerpt from the book In Defense of Food, by Michael Pollan (which you should read after you read The Omnivore’s Dilemma, by the same author).
“There’s no escaping the fact that better food–whether measured by taste or nutritional quality (which often correspond)–cost more, usually because it has been grown with more care and less intensively. Not everyone can afford to eat high-quality food in America, and that is shameful; however, those of us who can, should. Doing so not only benefits your health (by, among other things, reducing your exposure to pesticides and pharmaceuticals), but also the health of the people who grow the food as well as the people who live downstream or downwind of the farms where it is grown.”
