(Consumer news blog) When a middle school student near Dallas, heard her parents arguing about the value of organic foods, she was inspired to create a science fair project to try to resolve the debate. Three years later, her exploration of fruit flies and organic foods has not only raised some provocative questions about the health benefits of organic eating, it has also earned the 16-year-old top honors in a national science competition, publication in a respected scientific journal and university laboratory privileges normally reserved for graduate students. The research, titled “Organically Grown Food Provides Health Benefits to Drosophila melanogaster,” tracked the effects of organic and conventional diets on the health of fruit flies. By nearly every measure, including fertility, stress resistance and longevity, flies that fed on organic bananas and potatoes fared better than those who dined on conventionally raised produce.
While the results can’t be directly extrapolated to human health, the research nonetheless paves the way for additional studies on the relative health benefits of organic versus conventionally grown foods. Fruit fly models are often used in research because their short life span allows scientists to evaluate a number of basic biological effects over a relatively brief period of time, and the results provide clues for better understanding disease and biological processes in humans.
For her original middle-school science project, the student evaluated the vitamin C content of organic produce compared with conventionally farmed foods. When she found higher concentrations of the vitamin in organic foods, she decided she wanted to take the experiment further and measure the effects of organic eating on overall health. She searched the Internet and decided a fruit fly model would be the best way to conduct her experiment. She e-mailed several professors who maintained fly laboratories asking for assistance. To her surprise, Johannes Bauer, an assistant professor at Southern Methodist University in Dallas, responded to her inquiry. The student worked on the project over the summer, eventually submitting the research to her local science fair competition. The project was named among just 30 finalists in the prestigious 2011 Broadcom Masters national science competition. The professor, following his lab’s policy of publishing all research regardless of outcome, urged the student, then 14, to pursue publication in a scientific journal. The professor and an S.M.U. research associate are listed as co-authors on the research.
