A 2012 meta-analysis of data from 240 studies concluded that organic fruits and vegetables were, on average, no more nutritious than their cheaper conventional counterparts; nor were they less likely to be contaminated by pathogenic bacteria like E. coli or salmonella – a finding that surprised even the researchers. “When we began this project,” said Dena Bravata, one of the researchers, “we thought that there would likely be some findings that would support the superiority of organics over conventional food.”
2012年对240项研究结果的汇总分析显示：一般而言，有机水果和蔬菜并不比便宜的水果蔬菜更有营养，它们被大肠杆菌或沙门氏菌等致病菌污染的可能性也没有降低。就连研究人员都对这一结果感到惊讶。参与这项研究的德娜·布拉瓦塔说，“项目开始时，我们都认为很可能找到有机食品优于传统食品的证据。”
