Skip to comments.Is organic food more nutritious than non-organic food?

Scientists in Denmark have compared how organic and non-organic diets affect dietary mineral uptake in humans, focusing on copper and zinc. They found that there is no difference between the two diets when it comes to uptake and how the minerals are processed in the body.
Copper and zinc are two essential trace elements with unknown availability in organic verses non-organic diets. Alicja Budek Mark and colleagues at the University of Denmark investigated the content of these elements in non-organic versus all-organic diets fed to 20 men over 12 days. And Marks team assessed the in vivo absorption of zinc and copper by analysing faecal samples taken from the men during days 812.
Different fertilisers and farming techniques affect the mineral content of plants in different ways
The team found that there was no difference in the content and absorption of zinc and copper between the two diets. Mark comments that she hopes the work contributes to the on-going debate about the health benefits of organic foods, providing evidence that organic foods do not seem to be better than conventional foods with regard to intake and absorption of selected minerals.
The health benefits of organic foods are an area of intense research as the demand for organic produce increases. Different fertilisers and farming techniques are known to affect the mineral content of plants in different ways, which in turn could affect the bioavailability of minerals to humans during digestion of plant matter eaten. However, what happens after the ingestion of these foods is unknown.
Janet Hunt, an expert in nutrition at the Nutrition and Environmental Studies Section of the International Atomic Energy Agency in Vienna, Austria, says that some proponents of organic food claim improved nutrient content of organically grown food, or improved nutrient absorption and utilisation, and studies such as this one help to refute such unsupported claims.

“Organic” is largely a scam. Woe to us if we go fully organic. Everything in Africa is organic and they’re starving to death.
No.Just more expensive,
No.Just more expensive,
I would not be surprised if metallic minerals are metabolized differently from vitamins, antioccidents, and enzymes. A lot more research is needed, as well as much longer studies.
Soaking your vegetables in pesticide may not lower the nutrition value but there are other considerations here.
I won’t eat organic food!!!
All they do is throw shit at it and hope it grows!
I want mine raised with the proper fertalizers for the crop and soil used and pestisides to keep it bug free!!!
I had enough buggy crap before they invented DDT!!!
Organic is largely a scam. Woe to us if we go fully organic.
We get allot of organic food from Mexico!!!
Essentially, a "placebo" effect for veggies.
FReepmail me if you want on or off my health and science ping list.

Wash your hands, vegetables. Boil and fry your meat thoroughly. Boil baby-care vessels and such and you'll be ok.
The choice between organic produce and non organic is:
One apple has far less pesticides than the other. The apple with more pesticides will cumulatively do neurological damage to you, frequently upping your odds significantly of ending your life with Parkinson’s or Alzheimer’s.
The only thing I’ve noticed about “organic” foods is that they are smaller, way more expensive, and spoil much quicker than non-organic.
I know something about apples and pesticides. Can you produce a study proving your assertion?
I have been an organic gardener and farmer for over twenty years and enjoy having much healthier soil in which to grow my crops. I also enjoy the lower costs and healthier aspects of being “natural”. Not all organic producers practice a natural growing philosophy...as one vineyard owner explained to me years ago...if you have to spray an governmental ordained organic substance six times on your crops to handle a problem that can be handled with one spray of “chemicals” the chemicals are the more economical and indeed probably healthier way to go. At my level, I do not need to use chemicals ever...but, I have mainly limited my farming (small acreage) to grains and hay. My vegetable garden...which is about a third of an acre has never had a chemical on it since I purchased the farm about 18 years ago and it is highly productive and excellent, rich black soil.
Having said all this, I questioned a nutritionist (phd level) a few years back over which was more healthy to eat...they said that there has not been any research that has shown organic vegetables to be healthier...although there are indications that the growth hormones and antibiotics in meat may have been causing trouble for the last couple of generations.
“I know something about apples and pesticides. Can you produce a study proving your assertion?”
You may not be aware of this but farmers have much higher cancer rates than other occupations. Indeed, in my rural county in northern Illinois there are some cancer rates that are much higher than national average...because of the pesticides and fertilizers sprayed in area farmlands.
Here is a link that shows there has not been enough research done to “prove” casual relationship but the indications are very strong. http://www.ncbi.nlm.nih.gov/pubmed/9498903
Try GMO foods. They last forever.
How does one know if the foods are GMO? keep them in your fridge for two months. They do not spoil.
BTW, How do seedless grapes and seedless watermelon reproduce?
They have seeds!
BTW: Virtually EVERY food is Genetically modified. It use to be done through cross pollination, it can now be done genetically leading to more nutritious disease and pest resistant food sources.
It always strikes me as strange that everything we eat is so bad for us, yet the instances of food born diseases and poisonings have fallen to almost an unmeasurable level.
Everything we consume is killing us, yet people are living longer and longer.
One thing that can be said for organic foods - it significantly enhances the diets of those who grow, process, distribute, and sell them, since an endless variety of idiots pay through the nose for them, making the sale of organic foods far more profitable than selling non-organic foods.
Maybe you should do some reading of the research already done?
When asked about that point you change the topic entirely to farmers who are exposed to the pesticides they use over a lifetime at concentration rates far higher than any mere consumer of fruits or vegetables ever would be.
You're clearly an agenda pusher who doesn't know enough to be throwing around the claims you are, Wpin.
"Casual relationship" or "causal"? "Prove" in quotes? Really? "Indications are very strong?" Scientifically meaningless weasel words; yours is wild claims and phony argumentation worthy of a liberal.
It’s largely a vanity issue. “I’m really important so I have to eat organic. “
Growing organic makes more sense.
a study of a mere two trace minerals alone does not define an overall advantage, or non-advantage of “organic” foods vs foods not considered “organic”
definitely more study is needed, and in that the study periods need to be longer than a mere 28 days and the demographic sample needs to be larger than a mere 28 participants
I am not making a case here “for” organic food; I am only suggesting that the reported study is very inadequate for making a case “against” organic food
I never said anything about Parkinson’s, if you wish to debate or discuss a topic with me you will do so politely or not at all. Also, try making some kind of logical sense to your side of the discussion. If, you choose to apologize I will continue this discussion and will explain in more detail with more links for you. Otherwise forget it.
Not only are we living longer, but I remember my grandmother in her late 50s. Despite being born in 1898 and raised in a Russian village until she was 18 and despite being a marvelous gardener who did all her own baking and canning and cooking from scratch, she developed Type II diabetes and died at age 60.
I compare pictures of her to my friends and family 10-35 years older than she ever was and the older current folks still look younger than she ever did and all are more active, even the 90+ year-olds. All the currently extant people have lived exclusively on what was available at the supermarket for the past 60 years or so.
OTOH, at least two people I know in their early 60s who are/were ardent organic eaters and, in one case, also a vegetarian, both of whom had access to the best preventive and acute medical care, are either dead of heart disease or have a diagnosis of advanced cancer. One woman under 50 has episodes of atrial fibrillation, despite an organic, vegetarian diet since the age of 18. All were physically active and devotedly followed a *healthy* (according to popular consensus) lifestyle.
All of this is anecdotal, but perhaps it indicates that food is secondary to genetics as to morbidity and mortality.
I was an apple farmer and a scientist that knows a bit about pesticides; didn’t raise bulls, but I can detect BS when I see it.
I just tagged you. Your it. And remember, you started this.
I bet it was a long time ago when you grew apples...you seem confused. I did not relate anything to apples...I think are confused with someone else or just having a “senior” moment...or, maybe you used too much pesticides when you were a farmer/gardener... :)
Anyway, here is a link to some information about pesticide toxicity from the University of Florida... http://edis.ifas.ufl.edu/pi008
Here is another article from the National Cancer Institute:
Here is another one: http://www.ncbi.nlm.nih.gov/pubmed/22571220
These should keep you occupied for a while. I hope you enjoy them and learn to understand that there are health risks from pesticides...
Agreed that washing is always a good idea, but it does not remove all pathogens from produce. Cooking is the way to go for that, and it even breaks down many chemical residues that may not have been washed off. Irradiation is the best approach for killing foodborne cooties. It’s really a shame that Islam exists; imagine every home/restaurant with an irradiator in the kitchen. It would be the end of food poisoning as we know it.
This may be way more harmful than old good E.coli. What kind of radiation do you mean?
Exposure to ionizing radiation that will destroy the pathogenic DNA. Maybe a cobalt source.
This method has multiple shortcomings:
- ionizing radiation produces free oxigen ions in the food. Those are highly chemically active and cause deterioation of cells' membranes within human organism.
- it also breaks chemical links within natural biological sunstances of nutritional value (like vitamins, enzymes, etc.) producing others (benzol, formaldehyde) which are carcinogenic and simply toxic.
- some pathogenic species (including the above-mentioned E.coli) can endure being exposed to radiation and then procreate very fast uncompeted from the others.
- radioactive material requires accurate handling what is not the case of household use.
- the sterilisation process requires hours of time (4-8).
So, basic hygiene methods look way more preferable.
If you do a good job at home or have an organic farm nearby that does a good proper job.... The organic produce you get will have more minerals than conventional produce. I can’t say how the organic produce is that you find at Whole Foods. It comes from many sources
So organic means no harmful sprays and if done right you get less watery and more minerals in your produce. I halfway practice this. I don’t spray but I do use a tiny bit of chem fertilizers that have trace minerals. Mulch a lot with wood chips to get the soil black with humus
