Fruit flies fed organic diets are healthier than flies fed nonorganic diets, study finds

Flies on organic food performed better on some health tests "The data demonstrated that flies raised on organic food extracts by-and-large performed better on the majority of health tests," reported the researchers.

It remains unclear why organic diets delivered better health, the researchers said.

The Bauer lab results come at a time when the health effects of organic food are widely debated.

Prior studies by other researchers have found conflicting results when reviewing the scientific literature for data. While several studies have shown elevated nutrient content and lower pesticide contamination levels in organic food, a recent publication reporting a large-scale analysis of all available studies concluded no clear trend was apparent.

Fruit flies were fed extracts from produce purchased at a grocery store

In order to investigate whether organic foods are healthier for consumers, the lab utilized one of the most widely used model systems, the fruit fly Drosophila melanogaster. Because of the low costs associated with fly research and the fly's short life cycle, researchers use fruit flies to study human diseases, from diabetes to heart function to Alzheimer's disease.

The Bauer lab fruit flies were fed organic and nonorganic produce purchased from a leading national grocery retailer of organic and conventional foods.
