The point behind organic food is that it's better for the environment, not healthier to eat. But thanks for the useless study, UK!
I'm not so sure that's the point either. That might have been the original (if not necessarily well conceived) idea. As it stands now the point behind organic food is mark up what are essentially inferior food stuffs. I know it makes most people feel like they are doing a good deed by paying twice as much for organics, but in truth the issue is a lot more complex. You could make the case that certain types of farming which is deemed organic might locally be "better for the environment". If we assume that the types of farming deemed organic were ubiquitous, we have quite a different story on our hands.
What's perhaps more interesting about organics is how it captivates people's hearts. Indeed, many people who are otherwise skeptical tend to employ some degree of the appeal to nature fallacy.
