Scientists Say Organic Food May Not Be Healthier For You
Hugh Pickens writes "NPR reports that although organic fruits and vegetables, grown without synthetic pesticides or fertilizer, comprise a $29 billion industry that is still growing, a new analysis of 200 peer-reviewed studies that examined differences between organic and conventional food finds scant evidence of health benefits from organic foods. 'When we began this project, we thought that there would likely be some findings that would support the superiority of organics over conventional food,' says Dr. Dena Bravata, a senior affiliate with Stanford's Center for Health Policy and co-author of the study published in the Annals of Internal Medicine. 'I think we were definitely surprised.' Some previous studies have looked at specific organic foods and found that they contain higher levels of important nutrients, such as vitamins and minerals. For example, researchers found in one study that tomatoes raised in the organic plots contained significantly higher levels of certain antioxidant compounds. But this is one study of one vegetable in one field; when the Stanford researchers looked at their broad array of studies, which included lots of different crops in different situations, they found no such broad pattern. Here's the basic reason: When it comes to their nutritional quality, vegetables vary enormously, and that's true whether they are organic or conventional. One carrot in the grocery store, for instance, may have two or three times more beta carotene than its neighbor. But that's due to all kinds of things: differences in the genetic makeup of different varieties, the ripeness of the produce when it was picked, even the weather. Variables like ripeness have a greater influence on nutrient content, so a lush peach grown with the use of pesticides could easily contain more vitamins than an unripe organic one."
Is anyone actually surprised by this?
Organic food is not sprayed with synthetic pesticides. They may or may not have pesticide residues, and the synthetic stuff is generally safer.
Yep. 99% of the flavor of a tomato is whether it was picked when it was red on the plant or picked when it was green then ripened in a truck on the way to the store.
You can try it at home if you have plants. Pick a green one and ripen it on a window ledge. When it's nice and red pick a red one off the plant and compare the flavor. Remember, these are from the exact same plant...
Taste has very little to do with organic vs. inorganic and an awful lot to do with how it spent its last few hours. Stuff which ripens fast then goes mushy (bananas, tomatoes, strawberries...) is very susceptible to this.
No sig today...
You are measuring it wrong. So is the TFA and the damnfool study it is based on.
Organic farming is not about tastiness. It is about using farming methods that enhance the local ecosystem rather than relying on fertilizers and pesticides that cripple big parts of the ecosystem, both at the farm and downstream from its fields. The opposite of organic farming is Monsanto, Round-Up, and burning 7 Calories of diesel fuel to get 1 Calorie of lettuce to market.
That many who buy organic food find it tastier has to do with same factors that make a Thanksgiving Day turkey taste better than a turkey served up on a sweltering July day. Taste is an experience with a rich psychological component involving memories and future expectations. It is not simply a matter of signals from neurons on the tongue.

Of course organic food is sprayed with pesticides. I try grow my own food as organic as possible and use pesticides all the time. Do you think magic keeps the bugs off? I just put up a sign that says "Dear bugs I'm trying to grow organic food here, please leave"?
No the difference is we use pesticides and fertilizers that are derived from natural sources. But some of the pesticides are still hazardous if used incorrectly. Many are toxic to fish and amphibians.
I love Jesus, except for his foreign policy.
I can always tell the difference between organic and inorganic food. The inorganic food is always either gritty or metallic.
How to break this gently?
You're not eating the packaging, are you?
Faster! Faster! Faster would be better!
That's crap.
In the long run intensive farming destroys the productivity of the soil and the side affects of the run off fertilisers severely harm other neighbouring eco-systems like waterways. So in the short term yes "modern" intensive farming boosts production but long term the balanced more "natural" organic approach is sustainable because it nurtures a healthy biodiversity. Go and read the UN millennium report on biodiversity and human health, perhaps the biggest pulling together of science on the affect of man and farming practises.
The NPR article and the study that it reports upon starts with the wrong premise. Taste is not the only consideration. Here are some other issues that should be considered when purchasing food:
Localvore:
-Was the food grown locally, benefitting local farmers, or does the apple sauce come from China, and blueberries from Chile?
-Does the food grown distantly consume more fuel to bring it to market?
-Do you mind eating frozen foods that are out of season locally?
-Does supporting local farmers create a more vibrant local economy?
Contamination:
-Do environmental conditions and industrial food processing allow the food to be contaminated?

Fertilizers:
-Does your purchase support farming that pollutes rivers, creates brown tides in estuaries, and dead zones in the ocean?
-Is the fertilizer derived from petroleum, and does that process cause pollution of it's own?
-Is the fertilizer biologically contaminated? (For instance, E-coli)
Pesticides:
-Does the method of farming reduce beneficial insects, such as bees?
http://en.wikipedia.org/wiki/Colony_collapse_disorder
-Are their traces of pesticides left in or on food items?
http://en.wikipedia.org/wiki/Daminozide
Biodiversity:
-Do you want to support a system of monoculture which eliminates varieties of plants and animals because they are not commercially profitable?
-Does the increasing lack of diversity contribute to disease blights which wipe out crops such as potatos and bananas?
-Does growing invasive species create a risk for local wildlife

Sustainability:
-Is the farming method water neutral?
-Does the farming method create dust bowls?
-Can the farming method be sustained in the long term?
http://en.wikipedia.org/wiki/Three_Sisters_%28agriculture%29
Processing:
-Does industrial processing, mechanical separation, and handling contribute to contaminiation? (For example, salmonella)
-Is the jar of peanut butter filled with corn syrup (non-seperating), more healthy to eat than the one that contains only peanuts (oli seperates)?
-Does the processing of the food kill off beneficial bacteria flora?

GMO's:
-Do the tomatos on the store shelf have fish genes spliced into their DNA?
http://thegreendivas.com/2011/06/10/waiter-theres-a-fish-in-my-tomato-a-gmo-story/
-Are foods that create their own pesticides safe to eat?
-Have GMO plants and animals proven themselves to be historically safe, with minimal unforseen consequences?

Political:
Do you want to support ADM and Monsanto who manipulate the FDA and sue farmers who choose not to use their products?
Do you want to support banana companies, and coffee companies that mistreat and neglect workers?
Is it rational for countries such as Ethiopia to grow crops for corporations to export while starving local populations recieve international food aid?
The answers to these questions cause me to support local, organic, sustainable products wherever I find them.
