It seems there is little evidence that organic foods are more nutritious than conventionally grown foods, according to the most comprehensive study to address the question to date. However, the findings by researchers at Stanford University, California, do suggest that eating organic foods can reduce the likelihood of consuming pesticides(农药)and antibiotic-resistant bacteria.
Lead author Crystal Smith-Spangler and a team of researchers looked at 240 published studies of the nutrient and contaminant levels in organic and conventionally grown foods, as well as studies of humans consuming the two types of food. He writes in the Annals of Internal Medicine: " Despite the widespread misperception that organically produced foods are more nutritious than conventional alternatives, we did not find evidence to support this perception. "
They found no consistent differences in the vitamin content between the two types of produce or that conventional foods pose any greater health risk than organic ones. They also found that the risk of bacteria E. coli(大肠杆菌)contamination was unrelated to fanning method.
However, their analysis did find that conventional produce carries a 30% higher chance of pesticide contamination when compared with organic foods.
Commenting on these results, Smith-Spangler said: "This study is not able to give consumers hard information about the impact of pesticide contamination on health because there are so few human studies available. Based on our result, people who do not wish to have exposure to any pesticide residues(残留物)may prefer to choose organic foods for that reason. However, people who understand that there are regulations to ensure the safety of our food supply may be less concerned, because it is unusual to have pesticide residues exceeding our maximum allowed limits. "
Interestingly, an FSA report earlier this year revealed the presence of carbendazim(多菌灵), a suspected hormone-disrupting chemical banned in the U. S. , in fruit and vegetables even after washing and cooking. Under organic regulations, these chemicals are banned, making buying organic food a simple solution to avoiding chemicals which remains the top reason for consumers to do so.
It should be noted that there are currently no long-term studies of the health outcomes for people consuming organic versus conventionally produced food. Given that people who regularly consume expensive organically grown products tend to be richer—a factor strongly associated with better health outcomes—this might be a tricky study to design. [br] The author suggests that people who often consume organic foods tend to be richer and have______.
