Looks like Pat was right
We are interested in Organic gardening primarily to maintain he health of the planet, and secondarily our ow health. Pnbrown posted some time ago how despicable modern wheat is, and the proof is in the paper above, published 2 weeks ago. (Brief summary: subjects with some irritable bowel syndrome were fed identical diets, one with regular wheat for bread and pasta, the other with heirloom wheat. Heirloom subjects had better guts, better defecation, and lower blood inflammatory markers).
Note that a diseased gut is at the base of all inflammation and thought to be a major factor in all diseases of civilization. This is interesting because alternative theories posited that modern mills produce hyperfine flour, and that bigger flour grains in the past were carrying protective granules of resistant starch to the lower gut. It seems that hyperfine flour is, at most, a minor problem.
