It's a matter of contention that "organic" food products are intrinsically healthier than those grown with modern farming techniques using pesticides and synthetic fertilizers. Now, Pia Knuthsen and colleagues in Denmark have demonstrated that in one sense organic onions, carrots, and potatoes really are no healthier as they do not have higher levels of healthful antioxidants. The researchers analyzed polyphenolic antioxidants in onions, carrots and potatoes grown using conventional and organic methods and found no differences in concentrations. "On the basis of the present study carried out under well-controlled conditions, it cannot be concluded that organically grown onions, carrots, and potatoes generally have higher contents of health-promoting secondary metabolites in comparison with the conventionally cultivated ones," the team states.
Organic no better
