In the introduction to Michael Pollan's book In Defense of Food: An Eater's Manifesto," the author offers a quick summary of what people should eat for optimum health (and environmental sustainability): "Eat food. Not too much. Mostly plants."
The sentence seems simple enough, but abiding by it can be a challenge. Whole foods – foods that are in much the state they were when they came from the farm – are the minority in most grocery stores today. The more processed a food, the more resources it takes to produce, generally the more packaging it comes with, and the less nutritional value it tends to have.
