In what had to be a a major blow to the natural-is-good crowd, "a systematic review of 162 scientific papers published in the scientific literature over the last 50 years...found there was no significant difference" between organically grown food and food created by other means. Researchers from the London School of Hygiene & Tropical Medicine said:
"A small number of differences in nutrient content were found to exist between organically and conventionally produced foodstuffs, but these are unlikely to be of any public health relevance. Our review indicates that there is currently no evidence to support the selection of organically over conventionally produced foods on the basis of nutritional superiority."
I had always wondered about organic foods, and what exactly the supposed benefits were. The most common response is that they are "natural", but so are cyanide and botulism, so I found that argument entirely unconvincing. Now we find the science is lacking for alternative nutrition (at least this piece of it) just like it is lacking for alternative medicine.
This once again shows that conservatives don't have a monopoly on pushing pseudoscience. Leftwingers like The Huffington Post do their share of misinforming, and politicians like Tom Harkin waste millions in taxpayer money on pseudoscientific nonsense. Conservative nuts are just more numerous, and more mainstream.
