Est in aqua dulci non invidiosa voluptas
I grew up around those organic munching folks and farmers. Organic food tastes better mainly due to the different varieties used, different harvesting, handling and butchering.
Though a lot is in the mind. I remember some blind taste tests done a while back by Consumer Reports that showed folks can't tell the difference in most foods. And the blind taste tests they do on water usually puts NY City tap water at the top!
Organic produce isn't pesticide free, it's free of synthetic pesticide. It can have legally have lots of rotenone, pyrethrins, copper sulphate and other such "organic" pesticides all over your "organic" produce.
Over 90% of pesticides you ingest are natural, and your body can't tell the difference between natural and synthetic toxins. Reducing intake of synthetic toxins will not make an even trivial difference in how hard your body works to clean out toxins.
That cyanide compound in apple seeds can make you very sick, even kill you. Those green spots on potatos represent a concetration of the poison solanine, and you should cut them out. Some goverments advocate eating less potatoes when pregnant.
We co-evolved with many of these toxins for millions of years, and cancer-causing natural things like the sun--and it sure ain't helped us!
I know few toxicologist that waste money on "organic" food. They know there are far more important things to do.
Fine paper here on it by some top toxicologists dispelling these pesticide fictions (warning pdf). The lead author runs the The Carcinogenic Potency Database at Berkeley.
