U.S. sales of organic foods and beverages increased from $1 billion in 1990 to $20 billion in 2007. People are willing to pay more for organic products because they think they’re healthier. Researchers at Copenhagen University disagree. In a study that included apples, carrots, kale, peas and potatoes, the researchers found organic produce doesn’t contain more nutrients than non-organic produce grown with pesticides. Of course, the study, published in the “Journal of the Science of Food and Agriculture”, didn’t look into the health risks of pesticides. JSFA is a chemical industry journal.
