“In 1999 the National Research Council concluded that 'the total exposure to naturally occurring carcinogens exceeds the exposure to synthetic carcinogens.'...The point was that even if organics were pesticide-free, the gain wouldn't make up for the downside of organic food: It's more likely to be infested with bacteria because it's grown in 'natural' fertilizer. Natural fertilizer is the health food business's euphemism for cow manure. (The much-criticized 'nonorganic' produce is grown in nitrogen fertilizers. Although organics advocates sneer at the chemicals, 'chemical' nitrogen is perfectly healthy; air is 78 percent nitrogen, after all. We have a choice between foods grown in nitrogen taken from the air, and 'organic' food grown in cow manure.)”
