Surely that's the null hypothesis? It's up to proponents of organic food to prove a benefit.

Ha, yeah sure, we need to proof that natures goods are fine the way they are supposed to be, but highly manipulated goods don't. That kind of thinking is one of the reasons why so many people fear TTIP. Please stay on your side of the Atlantic.

Weird thinking. While I agree that it's a sensible null hypothesis, I'm not sure I agree that the burden of evidence automatically should be on proponents of organic food.

"Organic" food is what we've eaten since the beginning of time. It'd make sense that you'd have to show that the alteration you're introducing to the natural state of affairs isn't detrimental to health of the consumer. I.e., I'm making the same argument as you, I just consider unaltered food to be the baseline.

Also, "organic" is a weird name. Organic as opposed to what? Bananas made out of mineral oil?

It is false to claim 'organic' food resembles what humans have been eating since the beginning of time. It bears little resemblence. That's kind of like saying maize and teosinte are the same plant.

(responding to @dgesang here, because of max comment depth) The conventionally-grown food looks similar, tastes similar, and people have been eating it for decades with no major, obvious consequences. So at first glance they are equivalent. So it seems reasonable that the burden would be on proving a difference, rather than an equivalence.

And organically-grown food have been eating it for EONS with no major, obvious consequences. 'Conventionally-grown food' have just been thrown on the market a few decades ago without knowing any long-term effects to humans eating them or to the environment they are grown in. I don't care about proof for equivalence or difference, I only care about safety. And any food should be proven to be safe BEFORE being released, not decades later.

It seems like the null hypothesis should be working in the opposite direction. Heavy use of pesticides and herbicides in "modern" farming are a few decades old, and some aspects of this trend, like "Roundup Ready(tm)" crops are very recent.

I'd rather be in the control group for this loosely organized experiment.

Selective breeding is a comparatively slow and safe process. You're altering a species within its own parameters. It has little resemblance to the frankensteining we're doing right now. I'm not against it, I'm just not sure we've a developed a proper test suite to secure the process.

The dietary effects on health are poorly understood. Nutrition studies are fraught with difficulties and have spawned a resurgence in methodology concerning "measurement error" in the field of statistics. You don't really know how much pizza you ate last year, but the survey will ask you to estimate it somehow... and this kind of measurement is 'noisy'.

Conventionally-grown food looks like organically grown food on steroids, to me. I suppose from the outside a human on steroid may look healthy -- Mr Universe, even -- but we know all is not well inside.

I'm not saying that's really related, but there is substantial evidence for real differences in the makeup of food grown conventionally vs organically.

Citations 10-15 in the paper the original article pertain to this - protein expression differences across fertilization types.

Quantitative proteomics to study the response of wheat to contrasting fertilisation regimes - http://vwordpress.stmarys-ca.edu/bdf2/files/2013/05/wheat-an...

"... The abundance of 111 protein spots varied significantly between fertilisation regimes. Flag leaf N and P composition were significant drivers of differences in protein spot abundance, including major proteins involved in nitrogen remobilisation, photosynthesis, metabolism and stress response."

> If people don't want organic food, I could generally care less except for one thing: efforts to put legal roadblocks in the way of locally grown food. How do you know that locally grown food is organic unless someone checks? Local grown and sold food doesn't necessarily mean "organic" it just means locally grown. Pesticides and chemicals are available for local growers too. Unless you grow it or personally know whe…

People in this thread seem to be under the misapprehension that organic farming doesn't use pesticides or 'chemicals'. Everything is a chemical, and organic farming in particular uses some nasty ones (rotenone, copper sulfate, pyrethrins). Pesticides are not automatically bad - in fact some of them are almost unbelievably benign to humans and/or to the environment.

>Pesticides are not automatically bad - in fact some of them are almost unbelievably benign to humans and/or to the environment.

I'm curious to know which pesticides fit this description.

I take it you haven't listened to anyone pro-organic speak? Just a few short sentences with them and you would have been aware that they make outrageous claims regarding the health benefits of organic food. And it's precisely because of that that the onus is on them to prove it. And you can't just say "we don't have to prove it because we've always eaten organic and that's natural", err or whatever argument they use. That's a prime example fallacious logic.

Ha, yeah sure, we need to proof that natures goods are fine the way they are supposed to be, but highly manipulated goods don't. That kind of thinking is one of the reasons why so many people fear TTIP. Please stay on your side of the Atlantic.

I'll just go ahead and leave this here for you:
