Various studies in recent years have shown that some organic fruits and vegetables have nutritional advantages over conventionally-grown produce. For instance, organic tomatoes contain more vitamins, and organic tomato juice has more phenolics, a class of molecules that promote the body’s own antioxidant response.

But it’s been unclear exactly how organic farming brings about these changes in fruit.

Before you forswear all greens, however, bear in mind that low pesticide levels aren’t the worst thing in the world.

At her Science Sushi blog on Scientific American’s network, Christie Wilcox explains that a little bit of pesticide exposure can actually be good for you.
