Fruit flies fed organic diets are healthier than flies fed nonorganic diets, study finds
Date:3/26/2013

ided any confounding effects of a mixed diet.

The health tests measured longevity, fertility, stress and starvation resistance.

Findings suggest beneficial health effects dependent on specific foods

Some negative or neutral results were obtained using diets prepared from organic raisins, which suggests the beneficial health effects of organic diets are dependent on the specific food item, Bauer said. That might explain some of the inconsistent results in the published studies in the scientific literature, he said, noting some studies suggest there is a nutritional benefit from organic food, while others suggest there is not.

"To our surprise, in the majority of our tests of flies on organic foods, the flies fed organic diets did much better on our health tests than the flies fed conventional food," Bauer said. "Longevity and fertility are the two most important aspects of fly life. On both of these tests, flies fed organic diets performed much better than flies fed conventional diets. They lived longer, had higher fertility, and had a much higher lifetime reproductive output."

Factors such as soil condition and latitude where the produce was grown weren't considered, mimicking a typical grocery store shopping experience.
