NEW YORK (Reuters Health) Consumers who opt for organic foods often believe they are improving their health, but there is currently no strong evidence that organics bring nutrition-related health benefits, a new research review finds.
A "disappointingly small" number of well-designed studies have looked at whether organic foods may have health benefits beyond their conventional counterparts', according to the review, by researchers with the London School of Hygiene and Tropical Health in the UK.
Moreover, they found, what studies have been done have largely focused on short-term effects of organic eating -- mainly antioxidant activity in the body -- rather than longer-term health outcomes. And most of the antioxidant studies failed to find differences between organic and conventional diets.
The review, published in the American Journal of Clinical Nutrition, adds to findings reported last year by the same research team.
In that study, the researchers combed through 162 articles published in the scientific literature over the last 50 years, and found no evidence that organic and conventional foods differ significantly in their nutrient content.
For the current review, the researchers were able to find only 12 published studies that met their criteria for evaluating the health effects of organic foods.

That's really what it's all about. The placebo effect (placebo = latin for roughly "I will please") is very powerful. You can find placebo effects in drug studies of over 20%. I am not sure about the studies of feeling "righteous and pure", but as an aging former hippie, I suspect that the effects are more about the moral vanity that has afflicted my generation.
I don’t pay as much attention to buying “organic” as much as I do buying “local”. Living in Michigan I buy local as much as I can. Be a true conservative. Buy local first.
Years ago professor Bruce Aimes of UC Berkeley did an extensive study of naturally ocurring chemicals such as those in foods and man made chemicals. The study included hundreds of thousands of chemicals.
In general he found man made chemicals were less toxic and carcinagenic than natural chemicals but not by a wide margin.
He compared the toxicity of then used more powerful pesticides with the toxins found in many common foods taking into account the range of amounts people might consume. He then listed the most dangerous in order. None of the top 20 were man made pesticides or antibiotics (which are fully metabolized by the time the animal is processed)etc...
I do not recall the most dangerous in order, but some were coffee, peanuts, naturally grown and untreated corn, wheat and other grains, celery etc...
People stopped eating their lunches during his presentation. But, he reassured them by saying the human system was made to handle normal amounts of toxins and not to worry about it. His advice was don,t smoke, or drink excessively and wear seat belts.
As a scientist, I have found that the people who are gaga about natural or organic foods know very little if anything about bioscience. The “no genetically modified foods” people are really freaky as every food one eats now has been greatly genetically modified by nature or man over time. Read Guns Germs and Steel to get a layman’s description. The only result of eating “organic” food is a weight loss-—in your wallet.
I don’t have intestinal worms because I don’t eat organic grown food...
And I hope you enjoy them.
I will continue to consume and enjoy my pesticide protected, hormone added, chemically fertilized, industrially farmed meats and produce, which has allowed Americans and other industrial-farm nations to have the highest standard of living and longest lifespans the world has ever seen.
But you go ahead. Enjoy those weevils in your corn, e-coli outbreaks and fantastically high prices. It’s a free country! Sorta...
I buy organic milk because it seems to spoil more slowly than the usual stuff. The organic is still good on its “use by” date, whereas the regular milk sometimes seemed to be spoiling as it came out the door of the store.
Bad idea - When organic foods are attached by viruses, or insects or mold, or birds etc., they develop internal toxins and antibodies(just like we do). Those defense mechanisms are cancer causers. Pesticides wash off the toxins don't.
Eat free range chicken? Same problem but worse.
But hey its your money.
Which means that it is also lower in vitamin content and the proteins have been damaged.
So you are actually ahead of the game if you drink the two buck a gallon stuff rather then the four dollar a half gallon over processed stuff that is labeled "Organic".
... which have...
Sorry. Just got up. First cup of coffee.
Milk taste better organic, vegis, chicken, fruits; steaks do not. Cheese, bread... stuff just taste better. Poison? No thanks; grew up on a farm and I haven't a lot of respect for the king-size bastards whom bought out the small farmers and turned farming into a ridiculous industry of wanna-be cowboy/farmers who grew up limp-wristed and lame.
As I type, I’m cooking some spinach from my garden, I know that cooking it loses some of the nutrients but I’m replacing them with bacon grease.
Chocolate milk comes from brown cows.
Well, no. The taste differential between milk labeled organic and the regular stuff is caused by the fact that they are processed differently. Organic milk, just like aseptic milk has been subjected to ultrahigh temperature processing. This lowers the vitamin content of the milk and destroys some of the proteins but it caramelizes the sugars which makes the milk taste sweeter.
If you like the sweeter taste then you would be better off buying the aseptic milk which tastes the same but is cheaper and has a much longer shelf life.

Explain strawberry milk.
I do trust the food from my local grocer. It’s a food co-op, and a locally owned store. Most of the produce is local (including many winter crops), and what the stores sell is what the owners and members feed their own families.
But you are on your own for banana milk.
so pesticides are good for you?
My point was that not all things organic are better than synthetics. The wide availability of high quality, inexpsnsive foods can be traced directly to science - including artificial pesticides, fungicides, fertilizers, and engineered/hybrid seeds.
