Why? Just like vitamins: it doesn't matter if a plant made a given

compound, or a chemist. If a compound affects how a fungus

synthesizes its cell wall by inhibiting an enzyme only the

threatening plant fungus produces, how is this going to affect



Please refer to some of the latest opinions of Dr Bruce Aimes, the

legendary biochemist at UC Berkeley who came up with the Aimes test

which was so widely used in the 70's to test compounds for their

mutagenic capacity. Results from these experiments were extrapolated

into conclusions that tons of additives in our food supply were

cancer-causing. He later tested extracts from mushrooms and celery

and tons of other plants. Lo and behold, it was either mushrooms or

celery, but one of these was far more mutagenic than any food

additive he had tested. The point being, and Dr Aimes has expressed

these ideas in several popular press articles (I can't remember

exactly where I've read them), that we eat loads of compounds every

day in the plants we eat that have the capacity to kill insects and

other competing organisms. Yet, we are not affected. The threat to

human health posed by minute residues of man-made chemicals is so

small, and Dr Aimes predicts, can be totally counteracted by eating

fresh fruits and veggies because of the loads of antioxidants and

phytochemicals ineherent in these foods.


...just a thought to broaden one's perspective on the issue at hand.
