英语时差：有机蔬菜真的更健康吗？

Every time i go to the grocery stores，i consider buying Organic vegetables because they are supposed to be healthier or something，but they are also moreexpensive. So is it worth it to pay more for the supposed health benefits? Well, it might be worth it if organically grown vegetables are in fact better for you than vegetables grown using fertilizers and pesticides. But, at least according to one study, organic veggies are no more healthful than vegetables grown in conventional ways. Specifically, the study found that organic and non-organic vegetables have roughly the same amount of polyphenols–an antioxidant with supposed health benefits. There’s some evidence that polyphenols reduce the risk of heart disease and cancer. But when it comes to the organically and conventionally grown onions, carrots, and potatoes looked at in the study, there’s no evidence that the organic versions were higher in polyphenols.
