food is like a language, an unbroken information stream that connects every cell in your body to an aspect of the natural world. the better the source and the more undamaged the message when it arrives to your cells, the better your health will be. if you eat a properly cooked steak from an open-range, grass-fed cow, then you are receiving information not only about the health of that cow's body, but about the health of the grasses from which it ate, and the soil from which those grasses grew. if you want to know whether or not a steak, or a fish, or a carrot is good for you, ask yourself what portions of the natural world it represents, and whether or not the bulk of that information remains intact. this requires traveling backwards down the food chain, step by step, until you reach the ground or the sea.
