MNN: Organic food is good for flies, study finds

The Mother Nature Network covered research carried out in the fruit fly lab of SMU biologist Johannes H. Bauer by Plano, Texas, high school student Ria Chhabra in its March 27, 2013, article “Organic food is good for flies, study finds.”

Bauer, an assistant professor in SMU’s Department of Biological Sciences, mentored Chhabra in her research to examine whether there would be health differences to fruit flies fed an organic diet or a nonorganic diet. Chhabra’s study found that flies fed an organic diet fared better on important health tests, particularly fertility and longevity.

Fruit flies live longer and lay more eggs when they eat organic food, according to a study published by university researchers and an ambitious Texas teenager.

After listening to her parents debate the benefits of buying organic food, Ria Chhabra decided to take matters into her own hands. The Texas high-school student — along with biology researchers from Southern Methodist University — began studying how an organic diet affects the health of fruit flies, hoping to shed light on potential benefits for people.

Fruit flies and humans have lots of obvious physiological differences, but the insects are still common test subjects for studying human health, since about 77 percent of known human disease genes have a relevant match in the fruit-fly genome. And based on Chhabra’s research, both species may have a lot to gain by eating more organic food.

“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,” says SMU biologist Johannes Bauer, who served as Chhabra’s mentor, in a press release. “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.”

That’s a promising result, but as Chhabra points out, it’s still unclear why exactly the organic-fed flies turned out healthier.

“We don’t know why the flies on the organic diet did better,” says Chhabra, a student at Clark High School in Plano, Texas. “That will require further research. But this is a start toward understanding potential health benefits.”

Eating organic food may help you live longer—if you’re a fly, that is. A group of researchers from Southern Methodist University offered fruit flies extracts of different varieties of organic and conventional produce purchased at the same Whole Foods in Texas. They found that flies who fed on organic potatoes, raisins and soy enjoyed a significantly longer lifespan and were more fertile.

The new report follows a study published by Stanford researchers last year which found that organic produce wasn’t significantly more nutritious than conventionally-raised fruits and vegetables, provoking a debate on the merits of chemical-free food. While the new study’s authors stop short of saying that the results are as applicable to humans as to flies, they do suggest that other animals could reap some of the same health benefits.

Dallas Observer: SMU Researchers Prove that Eating Organic Makes You Live Longer — If You’re a Fly

Dallas Observer journalist Eric Nicholson has covered research carried out in the fruit fly lab of SMU biologist Johannes H. Bauer by Plano, Texas, high school student Ria Chhabra in its March 27, 2013, article “SMU Researchers Prove that Eating Organic Makes You Live Longer — If You’re a Fly.”

There was a minor furor in the media last year when a study conducted by a researcher at Standford’s medical school concluded that organic fruits and vegetables are no healthier than their conventionally raised counterparts. This wasn’t quite as newsworthy as the headlines made it sound, since the study was looking mainly at vitamin content of produce, not at the chemicals that were or were not sprayed on it. Precious few people buy organic carrots expecting through-the-roof levels of beta carotene.

Then again, maybe they should. A new study by researchers at SMU, which is clearly more definitive than the Stanford one because it’s newer, suggests that eating organic food may cause you to live longer. If you’re a fruit fly.

They chose fruit flies essentially because they’re easier to keep on an all-organic diet, since they can’t sneak off and binge on Twinkies and they don’t object to consuming a single type of liquified produce from Whole Foods (either potatoes, raisins, bananas, or soybeans, depending on the fly) for their entire lives. They also live for about a month, making it easier to parse out the effect of diet on lifespan.

The Atlantic reported this morning on the study’s results:

The Atlantic: Eating Organic Food Associated With Longer Lives (in Flies)

Fruit flies fed organic produce from Whole Foods lived longer and laid more eggs than those fed the store’s conventionally grown offerings.

PROBLEM: Last September when Stanford researchers came out with findings that organic food doesn’t confer any additional nutritional value, the world countered: Of course not. While organic fruits and vegetables can claim health benefits in that they lack any number of additives that come included with traditionally farmed foods, calling produce organic doesn’t make it any healthier than it already, by virtue of being a fruit or vegetable, is supposed to be.

Still, that doesn’t mean researchers can’t turn it around and ask if produce containing chemicals, preservatives, and hormones are, comparatively, a little bit less healthy. While we know organic food serves the interests of the environment, public health, and human rights, there’s a lot we still don’t know about its benefits for the individual supermarket shopper deciding between the banana with the “organic” sticker and the one that’s heaped in with the other, conventional foods.

METHODS: At Southern Methodist University, researchers raised fruit flies on extracts of typical grocery store produce. Different groups of flies received either organic or conventional versions of potatoes, soybeans, raisins, or bananas, all purchased from the same Texas Whole Foods.

RESULTS: Despite the relatively poor health exhibited by all — as happens when one lives its entire life consuming only one type of food — the flies who ate organic generally performed better on a number of health measures.

Specifically, diets of organic potatoes, raisins, and soy were all associated with significantly longer lifespans, with no difference seen between organic and conventional bananas. Flies raised on organic versions of all four foods were more fertile.

New research shows eating lots of organic food can lead to a healthier life — if you happen to be a fruit fly.

Scientists fed fruit flies extracts from either organic foods or non-organic, conventionally-grown foods, and found the organic group was healthier and lived longer than their counterparts.

“We don’t know why the flies on the organic diet did better. That will require further research. But this is a start toward understanding potential health benefits,” study leader Ria Chhabra, a student at Clark High School in Plano, Texas, said in a written statement.

That’s right, the study was led by a Texas high school student who got the idea from hearing her parents discuss whether or not it was worth it to buy organic foods for health reasons.

So, Chhabra teamed up with her mentor, Dr. Johannes H. Bauer, an assistant professor of biology at Southern Methodist University in Texas.

“It’s rare for a high school student to have such a prominent position in the lab. But Ria has tremendous energy and curiosity, and that convinced me to give this research project a try,” Bauer said.

The fruit fly, or Drosophila melanogaster, is used in Bauer’s lab and other research facilities to study human diseases including diabetes, heart disease and even Alzheimer’s. Fruit flies are widely used in research because they’re cheaper and have a shorter life cycle than other lab animal models.
