(British Journal of Nutrition, 2014) meta-analyzed 343 papers on organic vs conventional crops. Organic crops had higher polyphenolics (phenolic acids about 19%, flavonols about 50%, anthocyanins about 51%), lower cadmium, and fewer pesticide detections. That is a composition difference, not a proven clinical outcome, and it was criticized on methods. It still sits against this card's current line that nutritional differences are minor, which is the Stanford-meta side of a split literature.","source_url":"https:\/\/doi.org\/10.1017\/S0007114514001366","state":"open","raised_by":"human:Captain"}]}
