From diane.bourn@stonebow.otago.ac.nz Wed Aug 24 13:57:16 1994 Date: Wed, 24 Aug 1994 16:35:22 +1100 From: Diane Bourn To: sanet-mg@ces.ncsu.edu Subject: Organics and Nutrition - ref list Many thanks to everyone who responded to my request for info on the comparison of the nutritional value of organically and conventionally grown food back in June. Here is the list of refs I've compiled. Some of the refs are not easy to get hold of - if anyone would like more info about a particular ref please contact me. Basically I think that because so many factors can influence nutritional value of crops irrespective of farming system (soil type, climate, maturity etc) it is an extremely difficult question to answer. Some of the studies below are poorly designed with many confounding factors - consequently results are conflicting. I think it is more useful to compare the quality of organically and conventionally grown food on a much broader basis ( not just on the basis of one factor like nutritional value) including social, political and environmental dimensions. In any case most of the studies simply report the concentrations of a very small range of nutrients in a limited range of crops - this does not tell us much about nutritional value - bioavailability is rarely addressed.
