Am_Fear speaks good sense on this one - I don't know what they make of irradiation but a great resource for anyone are Michael Pollan's books, Omnivore's Dilemma and In Defense of Food. They chronicle the rise of the modern day American diet, the overproduction of corn, and our society's increasing dependence on High Fructose Corn Syrup. It explains alot, and his basic advice is simple: Eat (natural) foods. Not too much. Mostly plants.

The modern American diet is decidedly unhealthy, but it doesn't have to be. For about the last 4 months I've gotten a box of organic fuits and vegetables from a local farm every other week, for $30 a pop. My family and I eat way better, with more variety, more gusto, and all my indicators are heading in a better direction than they were before. We eat it, or it goes to waste - irradiation is irrelevant to me as a means of preserving what I eat. Frozen and canned foods and MREs, those are my supplements and emergency supplies. Meantime eat like there's no tomorrow!
