Pesticides in Organic food and Parkinsons

Please don't get me wrong, I'm not anti organic food I eat it myself
sometime, however July 2005 Scientific American has an interesting article
on Parkinson's. A side bar reads as follows....

"Some pesticides, including one routinely used in organic farming, can
induce parkinsonian conditions in animals."

"Emory University has also discovered in animal studies that exposure to
rotenone, a pesticide often used in organic farming because it's made of
natural products, is capable of inducing protein aggregation killing
dopamine-producing neurons, inhibiting the cells' energy-producing
organelles and giving rise to motor deficits".

It continues..

"Experts now accept that smoking and coffee drinking can be somewhat
protective - although clearly the risks of smoking far outweigh this
particular benefit"

It's a complicated old world!
