These antioxidant compounds, which go by names like flavonoids and carotenoids, are getting a lot of attention lately. Their effects remain somewhat murky, but scientists say they can protect cells from the effects of aging, or from the sort of damage that can lead to cancer.
Benbrook says this is a big reason why public health experts want us all to eat more fruits and vegetables: They deliver a good dose of antioxidants. And if organic produce provides more of them, he says, "we think that's a big deal."
Benbrook thinks there are a couple of reasons why they're seeing this result.
First, plants make these compounds to protect themselves when they run into challenges like insects or diseases. And organic crops, because they aren't protected by as many chemical pesticides, have to fight off more hungry bugs. "Plants in an organic field are getting chewed on," he says.
