Argument over whether organic produce is more nutritious than conventional varieties has been around for at least a decade, said Jeffrey Blumberg, director of the Antioxidants Research Laboratory at Tufts University in Boston. “Some studies have suggested that organically grown plants contain higher levels of healthful antioxidants, possibly because some antioxidants act as natural fungicides (杀真菌剂), pesticides and insecticides,” he said. “The idea is that, without help from industrial chemicals, plants on organic farms need to work harder to protect themselves. They end up becoming more nutritious as a result.” But plenty of other studies have shown no such relationship.
“I understand that organic farmers would love to be able to say that theirs are super-fruits and super-vegetables because there are higher amounts of these compounds in them,” Blumberg said. “If you want to buy them because you think they’re safer for the planet to grow things that way, or because you think pesticides are bad for you or your family, or you like that they come from a shorter distance away, that’s great.”
“But if you want to buy them because they’re more nutritious, you’re confused, and we don’t know if that’s true or not.”
