Study: Conventional Produce has Less Nutrition than Organic

March 10, 2009

If the economy isn’t grim enough for you, just check out the February issue of the Journal of HortScience, which contains a report on the sorry state of American fruits and veggies. Apparently produce in the U.S. not only tastes worse than it did in your grandparents’ days, it also contains fewer nutrients – at least according to Donald R. Davis, a former research associate with the Biochemical Institute at the University of Texas, Austin. Davis claims the average vegetable found in today’s supermarket is anywhere from 5% to 40% lower in minerals (including magnesium, iron, calcium and zinc) than those harvested just 50 years ago.

If you’re still not buying the whole “organic food is better” argument, this study might convince you otherwise. As Davis points out, more than three billion people around the world suffer from malnourishment and yet, ironically, efforts to increase food production have actually produced food that is less nourishing. Fruits seem to be less affected by genetic and environmental dilution, but one can’t help but wonder how nutritionally bankrupt veggies can be avoided. Supplementing them is problematic, too: don’t look to vitamin pills, as recent research indicates that those aren’t very helpful either.
