“Organic” eating is a religion. [I comment as one with a lot of formal education in the chemistry of food and nutrition.] If it makes you feel righteous and pure, do it, but that’s all placebo effect. If you want fresh, do what I do and grow your own.
That's really what it's all about. The placebo effect (placebo = latin for roughly "I will please") is very powerful. You can find placebo effects in drug studies of over 20%. I am not sure about the studies of feeling "righteous and pure", but as an aging former hippie, I suspect that the effects are more about the moral vanity that has afflicted my generation.
