BBC News reports:
I found this report surprising. I know I thought organic was healthier - though I didn't get to the point where I was a devoted Whole Foods shopper.Researchers from the London School of Hygiene and Tropical Medicine looked at all the evidence on nutrition and health benefits from the past 50 years.
Among the 55 of 162 studies that were included in the final analysis, there were a small number of differences in nutrition between organic and conventionally produced food but not large enough to be of any public health relevance, said study leader Dr Alan Dangour.
Overall the report, which is published in the American Journal of Clinical Nutrition, found no differences in most nutrients in organically or conventionally grown crops, including in vitamin C, calcium, and iron.
The same was true for studies looking at meat, dairy and eggs.
What's interesting to me is that while this study seems fairly conclusive, it probably won't materially change the buying habits of those who have bought into the ideas and lifestyle of organic foods. Not only do organicphiles have their buying habits formed, but it's also a matter of cognitive dissonance.
Cognitive dissonance, according to Wikipedia, is, "an uncomfortable feeling caused by holding two contradictory ideas simultaneously...The theory of cognitive dissonance proposes that people have a motivational drive to reduce dissonance by changing their attitudes, beliefs, and behaviors, or by justifying or rationalizing their attitudes, beliefs, and behaviors."
In the case of organics, organicphiles for years have been paying higher prices for food that they believed was better for their health. They saw themselves as smarter for these purchases. When someone comes along though, and says, "We've looked at 162 studies and found that organic food is not materially more healthy," it shakes the bedrock of their belief. How can they be smart and tricked into buying more expensive food at the same time?
To solve this contradiction, one of two things can happen: the person can either admit that they were wrong (which feels like it invalidates their "smartness") or they can change the reason they were buying organic. Suddenly environmental or animal rights factors become more important. Or maybe they believe the studies were poorly conducted. Either of those assertions is easier than retraining a person's beliefs about themselves or habits in shopping.
So while this study is interesting to me, I am not shorting Whole Foods' stock anytime soon. The idea that organic is healthy is too ingrained in the mind of shoppers, and so I expect to see the trend toward organic continue to grow despite this report. Human behavior is fascinating.
Disclaimer: I know there are a number of people who do primarily eat organic for environmental and animal rights reasons. I also know that just because the additives farmers used in the past turned out to be healthy doesn't mean that additives in the future are going to be healthy. What I am more interested in is the human reaction to facts, and why they choose the behaviors they do, even in the face of contradictory evidence. So organicphiles, don't let me or this article stop you from enjoying!
