Stanford Study Flawed: Organic Produce May Be More Nutritious After All 305

According to Mark Bitman of The New York times the Stanford study was flawed. A spelling error skewed the results as well as the study ignoring several types of nutrients."

What really gets me is the false dichotomy between organic and conventional. It reminds me of how medical quacks try to differentiate between conventional and alternative (or naturopathic or whatever) medicine when the rational thing to do is to focus on what works, not what it is called. Some organic techniques are good. A lot of biological techniques like intercropping, crop rotation, focus on soil microbes, insect mating disruption, passive pest control methods like use of predator insects, increased use of biodiversity, ect. are positives. But that does not mean you should be dogmatic about it, which is exactly what organic is: naturalistic dogma. A natural pesticides is fine in organic production (and before anyone assumes organic uses no pesticides, look up the approved pesticide list), but not a synthetic one, simply on the basis of its origin? That is the classic appeal to nature fallacy. And while it is true that excessive fertilizer use has many negative consequences, why should responsible use of synthetic fertilizers be forbidden? Soil fertility management is damned complex, and it is presumptive to think only 'natural' methods are going to be of sustainable benefit. Genetically engineered crops are a great example of the naturalistic nature of the organic dogma. You can apply Bt to a crop, but if the crop does it itself, it is suddenly forbidden? Even something as simple as an apple modified to not brown can never be organic. Why? It is not natural (or rather, it is not natural and is popularized, unlike things like mutagenesis and chemically induced polyploidy).
My point is that organic has some things going for it, but not because it has some special label like 'organic'. What it has going for it are the biological techniques it uses. Of course, these techniques are not exclusive to organic; if you think your average farmer does not pay attention to things that can make their operations better, you are mistaken and have probably never even set food on an actual farm before. Ultimately, the focus should be on the scientifically verified merit individual practices, not on some label that represents a collection of practices grouped together based on the appeal to nature fallacy with some after the fact justification. The dichotomy misses the point entirely (unless the goal is marketing of course, in which case oversimplifications work great, and absolutes tend to create more true believers than nuance). Even if organic did produce more nutritious food, that would still not support the superiority of organic so much as it would indicate that there is an attribute of some growing method causing the increased nutrition that should be determined, explained, and focused on.

Which is fine - perhaps they do, and perhaps that's a great reason to choose organic. But the study wasn't attempting to answer the question "what possible reasons would people use to buy organic?" The study attempted to answer the question, "is there, in terms of nutrition - i.e., the chemical composition of the food - a significant difference between organic and non-organic food?" And the answer there, no matter how you spin and dance around the point, is "no, there is no significant nutritional difference."
The study was not flawed; the editorial is simply complaining that "they didn't study what I think they should have, and made a scientific conclusion that was narrow and precisely worded, when "organic is the best, always!" would have been a much better conclusion for the furtherance of my own personal agenda and preferences."

Conventional pesticides, by contrast, are generally synthetic materials that directly kill or inactivate the pest. Biochemical pesticides include substances, such as insect sex pheromones, that interfere with mating, as well as various scented plant extracts that attract insect pests to traps. Because it is sometimes difficult to determine whether a substance meets the criteria for classification as a biochemical pesticide, EPA has established a special committee to make such decisions.

Technically it's a spelling mistake which in practice meant the equivalent of searching for apples but counting the number of oranges instead, then writing up a paper on the astonishing lack of apples found.

But that HuffPo piece doesn't link to a primary source outlining the specifics of the critique. Both flavonols and flavanols are actual plant chemicals, what the evidence its a mistake? How many times was it made? I've looked and looked and can't find any direct info from Brandt (the scientist who found this) on this. I could be missing it, but given that this story is all over the place now and I can't find an original blog post or something with 15 mins of Googling is disturbing.

The New York Times gets a lot of (often well-deserved) criticism for its science reporting—but in this case, this isn't science reporting at all. It's written by Mark Bittman, and according to his website [markbittman.com], Wikipedia [wikipedia.org], and various other sources [observer.com], the author is a food writer and editor with a degree in psychology whose background mainly consists of writing and editing cookbooks and cooking magazines (and driving a cab).
Yes, pedigree doesn't mean everything and good science can come from people who aren't scientists. But still, consider the source and take it with whatever size grain of salt you feel is warranted.

Well, not necessarily. Inorganic compounds can still contain carbon. For example, diamond and graphite are considered inorganic. So, you can have a big old bowl of graphite/diamond stew and it's inorganic, but still has more carbon than pretty much any organic food.

My Dad, a member of the London Royal Society of Chemistry, noticed this about 10 years ago. Being a very scientific family*, it caused lots of double-takes and polite WTFs around the dinner table. After a little research on the subject, turned out it's the harvesting process that's organic:
"Organic salt cannot be 'organically grown' because it is a mineral not a plant. When salt is certified organic the certification refers to the process of collection of sea salt. The saltworks must be located in a nature reserve, without risk of pollution to the water, the salt must be produced by hand, without purifying the salt or including any additives, and it must fulfil the high standards in chemical analysis."

This article is so incredibly biased that it's hard to discover what's actually wrong with the Stanford research. This one reads like a raving lunatic jumping up and down because "the study didn't account for pesticides!" Well, it was a study that compared nutrition based on the nutrient content of the different production methods of food. Imagine that - they studied a bunch of numbers and totaled up their findings. Note that they did not study "which is worse for the environment", or "which food contains more residual agricultural chemicals", or "which tomato tastes better", or "which food contains more antibiotic resistant bacteria", yet those were the arguments he continually raised. That was not what this study studied!
Then he blames the study because “[t]he researchers started with a narrow set of assumptions and arrived at entirely predictable conclusions." Again with the "not really surprised" response. What did he think they were supposed to do, poll the newspaper food editors and ask them which variables to study? If they don't start with a specific set of assumptions and control for as many variables as possible, the results will be meaningless. So he's outraged because they didn't pick his particular variables? Get over it.
Now, could someone study the amount of residual pesticides in ordinary produce versus organically grown produce? Of course. Could someone study the human health effects of those doses of residual chemicals? Sure.
I, too, would like to see the study go even further. I'd ask the researchers to add just a few more data points and have it become meaningful not just to outraged food writers but to all Americans. They should compare the nutrition value per dollar spent in the grocery store, instead of nutrition values per gram. Then the food writers can publish that right next to the unemployment and poverty statistics, and maybe they can write another article about "how low-income people are ruining the ecology of this country because they don't buy as much organically grown food as gainfully employed newspaper food editors." Then we'd could measure his reaction to having both organically grown and genetically modified tomatoes being thrown at him.
