MAT’s post on the cultural consequences of corn colour, which we nibbled earlier today, has been brought to my attention. Immodesty forces me to note that we have explored similar byways here ourselves. Luigi experienced first hand contempt for yellow corn among a small sample of ethnic Africans. MAT’s assertion that “corn meal in the United States is yellow,” is undone by the clear north-south divide in preferences, noted here. ((Could some clever clogs please write a quick application to ask Facebook members their preference and mash it up with their location? Now!)) The whole business of yellow foods’ nutritional value is touched on in many places, not least here. And, of course, there’s the whole orange-fleshed sweet potato saga. Somehow, these “soft” ideas about culture seldom get the respect they deserve when talk turns to improving staple crops.
