A couple or three scary maps from the USDA’s Food Atlas that fairly clearly lay out the correlation (if not the causation) between food choices and health issues.
This one’s interesting: direct-to-consumer (farmer to consumer) food sales. I’d have to really dig into US Ag numbers to make sense of this, but it sure doesn’t look like there’s a correlation between a region’s agricultural output and the prevalence of CSAs and farmer’s markets. In other words, the more a region makes, the more likely they are to ship it out. You’ll find direct-to-consumer food sales not so much where the food is grown, but where the Wal-marts aren’t. We grow a lot of food in southern California, Texas, Florida, Georgia, and South Carolina … but we ship all of that food elsewhere (or, at least, package it for re-sale at grocers and big box stores). Meanwhile, in the Pacific Northwest, New England, and Colorado / New Mexico, folks are buying more of their food directly from the grower.
