10,000 times more pesticides 'naturally' in plants than synthetic residue on food

The word pesticide is misunderstood, nearly to the same extent as the word chemical. People have been led to believe, largely by the organic food industry and environmental activists, that pesticides are unnatural, dangerous, and do not belong in the food supply. But this defies a basic understanding of biology.

A pesticide is any chemical, natural or human-made, that is designed to kill another organism.

Using that broad definition, there are probably hundreds of thousands of pesticides in the natural environment. As it turns out, biological warfare was invented and perfected by Mother Nature.


And guess what? When we eat plants, we’re eating those pesticides, too. A paper co-authored in 1990 by the venerable Bruce Ames found that 99.99% of the pesticides we consume in our diet are produced by the plants themselves.


According to Dr. Ames’s team, every plant produces roughly a few dozen toxins, some of which (at a high enough dose) would be toxic to humans. Cabbage produces at least 49 known pesticides. Given the ubiquity of natural pesticides, Dr. Ames estimates that “Americans eat about 1.5 g of natural pesticides per person per day, which is about 10,000 times more than they eat of synthetic pesticide residues.”

Furthermore, Dr. Ames estimates that we consume 5,000 to 10,000 different natural pesticides every day, many of which cause cancer when tested in lab animals.

    This is a good introductory article, but should be greatly expanded to name some of them. Also, explain in detail why there is no testing done on just about all of the natural ones (there’s no statutory requirement to do so– and why not?), and that of those which have been studied with rigorous toxicology testing, some are proven mutagens, thus probable carcinogens.

    Oh please.

    “The word pesticide is misunderstood” so let me further the misunderstanding by “Using [an overly] broad definition” so that I can mislead you with fear mongering lies.

      Do you have any analytical laboratory results to dispute the findings of Dr. Ames?
