Thomas Sims gets it

Thomas Sims, Ph.D., is an Associate Professor in the Biological Sciences department at NIU. He was interviewed for a column about genetically engineered crops written for Northern Star Online, that claimed that GE foods are unsafe, quoting Dr. Oz, Jeffrey Smith, and the AAEM.

Here is an example of the claims made in the piece.

Between the U.S. and European countries, which has more instances of food allergies? Which has more instances of asthma or autism? Which has more instances of cancer and heart disease? Yes, I understand many factors play a role in these distinctions. However, I think it would be unwise to ignore the relation between the introduction of GM foods and higher instances of food-related allergies. Do you honestly believe major corporations care more about the health and safety of the public over their ability to make a profit?

His words only got a brief mention, and his response is a model for how scientists should respond to these kinds of claims. We have received permission to republish his spot-on commentary. (He has asked that I obscure the name of the young reporter who wrote the column so that it is about the information and not the person. So only the name has been edited.) Enjoy!

Column regarding genetically modified foods was one-sided and misinformed

This author’s column on Genetically Modified (GM) foods  is a thinly-veiled hatchet job, repeating a mixture of half-truths, lies and grossly misinformed opinions about this technology.

Does glyphosate restrict crop mineral uptake?

Note: This post follows Extraordinary claims require extraordinary evidence about Don Huber’s alleged letter to the USDA that claims a never before seen “micro fungus” is endangering all of agriculture.

While claims about “micro-fungi” are too extraordinary to even consider until extraordinary proof is provided (and preferably replicated by another lab and peer reviewed), Don Huber’s claims that Roundup (specifically the active ingredient glyphosate) weakens crops by binding minerals in the soil seems to have at least some merit, at least enough to be taken seriously and examined further.

Over the years since Roundup Ready (RR) crops have been released, independent researchers have conducted many studies to determine whether there is a specific problem with some crop varieties with the RR gene, with all crops with the RR gene, or with glyphosate itself. Overall, the research shows that there may be some concern about glyphosate reducing availability of some minerals when the soil is deficient in those minerals. The research hasn’t found a problem with the RR gene itself.

It is important to note that the stack of peer reviewed papers indicating glyphosate to be a problem with disease or yield is much smaller than the stack indicating there is no problem. We must look at the entire body of evidence, not just cherry pick one or a few papers, in order to get a clear understanding of what’s really happening.

Extraordinary claims… require extraordinary evidence.

Within the past few weeks, a letter written by a Dr. Don Huber to Secretary of Agriculture Vilsack has been making the rounds on the ‘net. The letter was allegedly given to the Farm and Ranch Freedom Alliance, and they claim to have confirmed that it was written by Dr. Huber. You can find the full text of the letter on the FRFA site with the ominous title Researcher: Roundup or Roundup-Ready Crops May Be Causing Animal Miscarriages and Infertility.

The story has been picked up by many bloggers, including Jill Richardson, and even made an appearance on Reuters. I haven’t seen any posts dedicated to a critical analysis of the letter, instead there is a rush to assume that it is correct, despite the lack of citations or other evidence provided for the extraordinary claims in the letter. The story is often accompanied with horrific pictures of dead fetal calves and the words “Emergency!” and “Danger!

Chat with Jeffrey Smith, Monday

On August 20th, our friends at the Non-GMO Project hosted a Facebook ‘book club’ with Robyn O’Brien, author of The Unhealthy Truth. I read the brief conversation after the fact, and not too much happened. There was a bit of self-congratulation of being ‘in the know’ along with some suggestions from the head of Mothers Are Demystifying Genetic Engineering (MADGE Australia inc.), Madeline, that cutting GE foods out of her diet had a noticeable

Produce Pesticide Rankings

My post Details on the Dirty Dozen on EWG’s Shopper’s Guide to Pesticides™ led me to dive into the 2008 USDA data to see just how contaminated (or not) our produce really is. There’s so much information that it’s a little difficult to work with, but with perseverance and the right software (JMP is the best!*), I was able to re-do the EWG analysis but with the newest available data.

Below you can find my results with a through explanation of what I’ve done and why. The results are posted without all the commentary at Produce Pesticide Rankings which has all of the results and Pesticide Produce Rankings Tables which has comparisons of my results to the EWG results. You can download the original USDA data yourself or check out the Latest PDP Findings of Interest to Consumers.
