Stanford Study Flawed: Organic Produce May Be More Nutritious After All
assertation writes "A few weeks ago an article was posted to Slashdot referring to a Stanford Study stating that organic produce, contrary to popular belief is not more nutritious. 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."
I just won the argument over this with my vegan vegetarian girlfriend. Now this! Damn it, Well, I won't being getting any for awhile. good thing the .XXX search is up.
I ain't gonna even look at these damn articles anymore. I'm gonna stick with cigarettes and chocolate cake.
And coffee.
And bacon. mmmmmm bacon.
"Elizabeth...I'm coming to join ya!"
just not covered in nasty pesticides and such. If it is tastier that would be a plus but I'd settle for not likely to introduce dna altering substances into my system.
errr....umm...*whooosh* *whoosh* Is this thing on ?
They both grow in dirt (organic and conventional), they are the same plant, they don't, on balance, have more or less of anything than the rest of the fruits and vegetables. Bottom line if you want to pay 3X as much for your food buy organic. If you just want to eat and get the most nutrition for your $$, buy conventional. And don't forget, we can't feed the world's population organically. Can't be done!
And organic produce is easier to digest than inorganic.

Second, this is not a scientific article. It is an editorial. Yes, I suppose Mister Bittman has a valid opinion, even some good supporting information to demonstrate that he has some understanding of the subject under discussion. Nonetheless, I don't think Mr. Bittman is even remotely what would be considered an expert in the areas of horticulture, agriculture, food production, nutrition, animal husbandry or any of at least a dozen other disciplines which might make his opinion any more informed than my own.
Not to criticize Mr. Bittman - he is an editorial author providing articles for a major news outlet. He has written a well thought-out, interesting editorial - but that's all. He doesn't have direct evidence to refute the findings of the Stanford Study - he doesn't even have any direct criticisms of the methodology employed by the Stanford group (which he should have, IMHO). What he has is an editorial opinion - well expressed, thoughtful, but at the end of the day still just his opinion.
This rebuttal is exactly why news reporting is so poor. This author has no scientific training, and his specific claims of the study being flawed betray that lack. To make his point he has to redefine the definition of nutritious from "more nutrients" to "lacking pesticides". This is why scientists are needed to peer review results - not some John or Jane Doe off the streets, or a certain New York Times journalist in an opinion piece.
The study is very clear - for a certain set of nutrients, organic produce does not have more than regularly grown produce. At no point does the author of this rebuttal ever attempt to show otherwise. The fact that the study didn't test everything doesn't make it flawed. The interpretation of the results - that organic produce is no more nutritious than regular produce - may be flawed. If the study contained the most important nutrients, then the interpretation is correct. Personally I'm going to give the benefit of the doubt to the Stanford scientist over the journalist until some serious peer review comes in. Frankly, there's nothing to see here but some journalist with an overblown sense of his own abilities.

You do realize that Nitrites and Nitrates are different things, right? In the cycle, first stage bacteria break down Ammonias (poisonous) to Nitrites (still poisonous) and second stage bacteria break down Nitrites into Nitrates (mostly harmless below 60-100ppm). It's up to your kidneys to flush what they can into your urine.
You missed some important points when you draw your conclusion:
That's a feature, not a bug. The role of a research paper isn't to make some broad sweeping conclusion, it's to carefully explore a narrow question, were the organics more nutritious, and on that question the answer was no.
This very important section of the article (emphasis mine) is conspicuously absent from your post:
Yet even within its narrow framework it appears the Stanford study was incorrect. Last year Kirsten Brandt, a researcher from Newcastle University, published a similar analysis of existing studies and wound up with the opposite result, concluding that organic foods are actually more nutritious. In combing through the Stanford study she’s not only noticed a critical error in properly identifying a class of nutrients, a spelling error indicative of biochemical incompetence (or at least an egregious oversight) that skewed one important result, but also that the researchers curiously excluded evaluating many nutrients that she found to be considerably higher in organic foods.
At this point that given that two research institutions have published metastudies with opposite conclusions, and that errors and oversights have been identified in the Stanford study, I'd have to say that the jury is out on this topic.
I always thought that the secret ingredient in Organic produce was copious amounts of horse shit.

Brandt wondered how the Stanford team, led by faculty from the School of Medicine and Center for Health Policy, could have found no difference in total flavanols between organic and conventional foods when her own results showed organics carried far more of the heart-healthy nutrient. Upon further inspection, she noticed that the team had actually calculated the difference in total flavonols, a different nutrient, and reported the result with the swap of an "o" for an "a".

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.

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.

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."
