A team of scientists laboriously reviewed decades of research comparing organic fruits and vegetables with those grown the usual way. They found that, as many had suspected, the organic produce, farmed without synthetic fertilizers or pesticides, was more nutritious, with more vitamin C, on average, and many more of the plant-defense molecules that in people help shield against cancer and heart disease.
That is probably not the study you heard about.
