Guest guest Posted October 19, 2006 Report Share Posted October 19, 2006 To claim that organic is a myth because big business has gotten into the game is a frail argument. While many organic firms have been taken over by larger corporations and produce organic to the " letter of the law " , there are still significant small producers, local growers, farmer's cooperatives, and medium to large size companies that produce quality organic foods in just the ways you envision. The fact that organic milk and eggs may, in some instances, come from factory farms does not change the fact that these farms, unlike the traditional ones you buy from, cannot use antibiotics, growth hormones, chemical pesticides and herbicides and have to feed their animals feed that conform to the same requirements. In fact, while Stoneyfield has grown into a large producer and requires milk from multiple sources (still organic) they actually appear to be doing a good job of maintain the organic standard in spirit and practice. I have aoften been suprised that for a group so focused on " optimal nutrition " that there is such disregard for organic, lack of concern for pesticide residue and no discussion at all about the higher nutritional value of eating local and organic produce. There are a variety of great books out there that talk about the negative components that go into non organic food and talk about the value, with scientific evidence to support it, for both organic, and even more importantly, local organic produce that does not have to travel the globe to get to your plate. For those of you that are interested the book Real Food is excellent, Harvest of Hope is interesting, What to Eat is very detailed and even Eat, Drink & Be Healthy by Harvard's top nutrition maven is a good general tome. Omnivore's Dilema, the book of the moment, addresses some of the " big organic " issues. If you want to differentiate between brands of milk so that you don't lump Safeway " O " in with Strauss Organic (just like you shouldn't lump Wonder " Bread " with the breads you likely buy (if you eat bread) then do a bit of web research - there is a great site that talks about " maintaining the integrity of organic milk " and ranks milk producers by various criteria that really helps show the range of differences that exists in organic dairy, just like they exist in every other category.

Guest guest Posted October 19, 2006 Report Share Posted October 19, 2006 Considering that the " idea " most people have of what organic implies and what is often promoted as by both the industry, the peddlers and the supporters, and the " reality " of the current state of the industry... with its watered down guidelines, reduced standards, and change in philosophy (i dont think they ever meant for there to be " organic twinkies " ).. Considering that the label " organic " doesnt even mean " organic " anymore , by the FDAs own standard... I would call the typical consumers concept of " organic " and the current status of organic a " myth " . But, that is just MHO.

Although there is an urgent need for information related to health benefits and/or hazards of food products of both origins, generalized conclusions remain tentative in the absence of adequate comparative data. Organic fruits and vegetables can be expected to contain fewer agrochemical residues than conventionally grown alternatives; yet, the significance of this difference is questionable, inasmuch as actual levels of contamination in both types of food are generally well below acceptable limits.

On the other hand, no differences can be identified for environmental contaminants (e.g. cadmium and other heavy metals), which are likely to be present in food from both origins. With respect to other food hazards, such as endogenous plant toxins, biological pesticides and pathogenic microorganisms, available evidence is extremely limited preventing generalized statements. Also, results for mycotoxin contamination in cereal crops are variable and inconclusive; hence, no clear picture emerges. It is difficult, therefore, to weigh the risks, but what should be made clear is that 'organic' does not automatically equal 'safe.' Additional studies in this area of research are warranted.

Guest guest Posted October 19, 2006 Report Share Posted October 19, 2006 I would agree that SOME organic brands do not represent the ideal that consumers envision, but that is not the whole picture. You have to pick your vendors just like in any other area. Also, there have been many attempts to dilute and weaken the " Organic " standard as presented by the USDA, but by and large those efforts ahve failed due in alrge part to consumer outcry. For those that want more stringent standards the Oregeon Tilth, and even more so the Japanese from what I understand, have stricter guidleines than the USDA. The USDA is not a great friend to the consumer in any area (being tasked primarilly with promoting industry and not health), but the standard is still a good one and, if not weakened, a far better choice than most. Many producers are going " beyond organic " in that they hold to what they consider a higher standard which often encompasses sustainability which is not addressed in the US standard. I agree that Organic Twinkies as a concept is a joke, but I am focussing on Produce and Dairy Products. if people can't see through the marketing hype (how about candy corn " made with honey " ) that junk food companies use to soften the impact then that is their own limited intelect or desperate need for a rationalization. What I fear is that people will throw out the baby with the bath water - look at Stonyfield's response - they support family farms, they buy organic milkl from family farms, they are active in building the organic milk supply. Another member forwarded me the link so Stoneyfields point by point: Setting the Record Straight http://www.stonyfield.com/AboutUs/setting_the_record_straight.cfm Organic remains, IMHO, a far better choice even if you don't research who the better vendors are. > > Considering that the " idea " most people have of what > organic implies and what is often promoted as by both > the industry, the peddlers and the supporters, and the > " reality " of the current state of the industry... with > its watered down guidelines, reduced standards, and > change in philosophy (i dont think they ever meant for > there to be " organic twinkies " ).. > > Considering that the label " organic " doesnt even mean > " organic " anymore , by the FDAs own standard... > > I would call the typical consumers concept of > " organic " and the current status of organic a " myth " . > > But, that is just MHO. > > There were some recent discussion on all the above in > the last month or two and I posted a long article > > Regards > Jeff > > Organic Food: Buying More Safety or Just Peace of > Mind?

Guest guest Posted October 19, 2006 Report Share Posted October 19, 2006 Hi Atherben: " I have often been surprised that for a group so focused on " optimal nutrition " that there is such disregard for organic, lack of concern for pesticide residue and no discussion at all about the higher nutritional value of eating local and organic produce. " Thank you for that input. From my point of view the question at issue is: " What is important? " Naturally my perception may be wrong, and I may find myself sometime in the future changing my view. However, my present perception in that more important are things like: how to adjust my fat intake to do the best I can to get the optimal amount and type (similarly protein and carbs I suspect also, but I haven't really got to that yet!); what specific steps to take to avoid various types of very nasty diseases; how to eat a range of foods each week to ensure an adequate intake of all the important nutrients even with a low caloric intake - especially those that not many foods contain. These keep me more than busy ferreting through studies that I hope will help me find the answers. By contrast, just my present opinion of course, whether some food item, while 50% more expensive, may have 10% more nutrient content of some nutrient I may have plenty of already; or worrying about microscopically small traces of substances some serious sources consider trivial (see the post on this that Francesca referenced); or being alarmed about polychlorinated biphenyls in fish, when the amounts claimed are measured in parts per TTTrillion (although the press release about the supposed contamination took the trouble to make sure they did *not* mention the word " trillion " , but expressed the concentration instead in terms the vast majority reading it would not understand was almost infinitessimally small). I might change my mind if I were to see some carefully conducted studies showing that mice or monkeys or whatever live longer or are perceptibly healthier if they eat organic instead of regular foods. Certainly that would make me sit up and take notice. If you know of any such studies (published in peer-reviewed journals) it would be of great help to people like me who remain largely ignorant of the dangers of consuming non-organic vegetables, etc..

Guest guest Posted October 19, 2006 Report Share Posted October 19, 2006 Proc Nutr Soc. 2002 Feb;61(1):19-24. Nutritional quality of organic food: shades of grey or shades of green? CM. High Sinclair Unit of Human Nutrition, School of Human Nutrition, School of Food Biosciences, University of Reading, UK. c.m.williams@... Consumer concern regarding possible adverse health effects of foods produced using intensive farming methods has led to considerable interest in the health benefits of organically-produced crops and animal products. There appears to be widespread perception amongst consumers that such methods result in foods of higher nutritional quality. The present review concludes that evidence that can support or refute such perception is not available in the scientific literature. A limited number of studies have compared the nutrient compositions of organically- and conventionally-produced crops, with a very small number of studies that have compared animal products (meat, milk and dairy products) produced under the two agricultural systems. Very few compositional differences have been reported, although there are reasonably consistent findings for higher nitrate and lower vitamin C contents of conventionally-produced vegetables, particularly leafy vegetables. Data concerning possible impacts on animal and human health of diets comprising organic or conventional produce are extremely sparse. Data from controlled studies in animal models, particularly within single species, are limited or poorly designed, and findings from these studies provide conflicting conclusions. There are no reports in the literature of controlled intervention studies in human subjects. Comparison of health outcomes in populations that habitually consume organically- or conventionally-produced foods are flawed by the large number of confounding factors that might contribute to any differences reported. If consumer perceptions regarding potential health benefits of organic foods are to be supported, more research of better quality is needed than that which is currently available.

Guest guest Posted October 19, 2006 Report Share Posted October 19, 2006 if you dont mind Francesca... I am just adding some more to our " data base " ... Int J Food Sci Nutr. 2003 Sep;54(5):357-71. Links Organic food: nutritious food or food for thought? A review of the evidence.Magkos F, Arvaniti F, Zampelas A. Department of Nutrition and Dietetics, Harokopio University, Athens, Greece. Apparently, one of the primary reasons for purchasing organic food is the perception that it is more nutritious than conventional food. Given the increasing interest towards organic food products, it is imperative to review the existing literature concerning the nutritional value of the produce, and to determine to what extent are consumer expectations met. There are only few well-controlled studies that are capable of making a valid comparison and, therefore, compilation of the results is difficult and generalisation of the conclusions should be made with caution. In spite of these limitations, however, some differences can be identified. Although there is little evidence that organic and conventional foods differ in respect to the concentrations of the various micronutrients (vitamins, minerals and trace elements), there seems to be a slight trend towards higher ascorbic acid content in organically grown leafy vegetables and potatoes. There is also a trend towards lower protein concentration but of higher quality in some organic vegetables and cereal crops. With respect to the rest of the nutrients and the other food groups, existing evidence is inadequate to allow for valid conclusions. Finally, animal feeding experiments indicate that animal health and reproductive performance are slightly improved when they are organically fed. A similar finding has not yet been identified in humans. Several important directions can be highlighted for future research; it seems, however, that despite any differences, a well-balanced diet can equally improve health regardless of its organic or conventional origin.

Links Comparison of health status between organic and conventional products.La Torre A, Leandri A, Lolletti D. CRA-Plant Pathology Research Institute via C.G. Bertero 22, I-00156 Roma, Italy. This paper reports the results of two trials carried out to estimate the hygienic-sanitary status of samples obtained from organic farming in comparison with products obtained from conventional agriculture. In three years of activity were carried out analyses on samples of common or durum wheat and on processing products like. flour, bran, macaroni and bread obtained from biological and conventional method. Also samples of vegetables and fruits were analyzed. The laboratory analyses have been focalized on qualitative and quantitative evaluation of fungal contamination and surveying of pesticide residues level. The great size of collected data has not highlighted substantial differences between the two analyzed typologies. About pesticide residues levels, generally they proved to be contained under the Italian legal limit, so both these products can be considered healthy under a hygienic-sanitary profile. The trials should be extended also to other cultivations like herbs, fruit-trees and vegetables to improve our knowledge's about qualitative and hygienic differences beyond the two methods of production and defense.

Guest guest Posted October 19, 2006 Report Share Posted October 19, 2006 Food Addit Contam. 2005 Jun;22(6):514-34. Quality of organically and conventionally grown potatoes: four-year study of micronutrients, metals, secondary metabolites, enzymic browning and organoleptic properties. Hajslova J, Schulzova V, Slanina P, Janne K, Hellenas KE, Andersson Ch. Institute of Chemical Technology, Department of Food Chemistry and Analysis, Prague, Czech Republic. Jana.Hajslova@... The quality of potatoes from organic and conventional farming was investigated in this study. Tubers of eight potato varieties, organically and conventionally produced at one or two geographical sites in controlled field trials, were collected in four consecutive harvests from 1996-1999. The parameters analysed included nitrate, trace elements (As, Cd, Co, Cu, Fe, Hg, Mn, Ni, Pb, Se, Zn), vitamin C, potato glycoalkaloids, as well as chlorogenic acid, polyphenol oxidase and rate of tuber enzymic browning. The results indicated lower nitrate content and higher vitamin C and chlorogenic acid content to be the parameters most consistently differentiating organically from conventionally produced potatoes. Elevated concentrations of glycoalkaloids were also observed throughout the experiments in some potato varieties grown in organic farming systems. Principal component analysis (PCA) of the analytical and other data using three PCs confirmed a good separation between the organically and conventionally produced potatoes when studied in single crop years. However, score-plots (objects) and loading-plots (variables) of pooled results from the consecutive harvests showed that between the years' changes and also variety as well as geographical variations are equally or more important factors determining the quality of potatoes than the farming system. Further studies of various marker compounds of potato quality related to the organic or conventional farming systems should be performed before unbiased information can be given to the consumers.

Guest guest Posted October 19, 2006 Report Share Posted October 19, 2006 The author I previouslly cited has several papers on PubMed on this same topic. These two are most relevant and perphaps this is a better format/source for her work: Worthington V. NutriKinetics, Washington, DC, USA. The increasing use of alternative therapies that rely on organically grown foods has renewed interest in the relationship between agricultural methods and food quality. The purpose of this article is to review the literature produced over the last 50 years comparing the nutritional quality of organic with conventional crops. Whereas few studies have been conducted, there is a trend in the data indicating higher nutrient content in organically grown crops. This phenomenon is possibly due to a higher water content in conventional crops, which causes nutrient dilution. For individual nutrients, existing studies show that organic fertilization practices produce crops with higher levels of ascorbic acid, lower levels of nitrate, and improved protein quality compared with conventionally grown crops. Although a theoretical rationale exists for possible effects of herbicides on nutrient content, few studies have examined the effects of these or other pesticides. Animal studies showed better growth and reproduction in animals fed organically grown feed compared with those fed conventionally grown feed. Further research is required to confirm the trends seen in the existing data and to clarify the exact relationships between agricultural management and nutritional quality. PMID: 9439021 [PubMed - indexed for MEDLINE] - I would note that the information on animal studies showing better growth and reproduction is more thouroughly detailed in her full article across multiple studies. Worthington V. Nutrikinetics, Washington, DC 20036, USA. nutrikin@... OBJECTIVES: To survey existing literature comparing nutrient content of organic and conventional crops using statistical methods to identify significant differences and trends in the data. DESIGN: Published comparative measurements of organic and conventional nutrient content were entered into a database for calculation. For each organic-to- conventional comparison, a percent difference was calculated: (organic - conventional)/ conventional x 100. For nutrients where there was adequate data, the Wilcoxon signed- rank test was used to identify significant differences in nutrient content as represented by the percent difference. Mean percent difference values were also calculated for each significant nutrient by study and by vegetable for the most frequently studied vegetables. The nutrient content of the daily vegetable intake was calculated for both an organic and conventional diet. RESULTS: Organic crops contained significantly more vitamin C, iron, magnesium, and phosphorus and significantly less nitrates than conventional crops. There were nonsignificant trends showing less protein but of a better quality and a higher content of nutritionally significant minerals with lower amounts of some heavy metals in organic crops compared to conventional ones. CONCLUSIONS: There appear to be genuine differences in the nutrient content of organic and conventional crops.

The aim was to obtain a metabolite profile for wheat (Triticum aestivum L.) grains grown under comparable organic and conventional conditions. These conditions cannot be found in plant material originating from different farms or from products purchased in supermarkets. Wheat grains from a long-term biodynamic, bioorganic, and conventional farming system from the harvest 2003 from Switzerland were analyzed. The presented data show that using a high throughput GC-MS technique, it was possible to determine relative levels of a set of 52 different metabolites including amino acids, organic acids, sugars, sugar alcohols, sugar phosphates, and nucleotides from wheat grains. Within the metabolites from all field trials, there was at the most a 50% reduction comparing highest and lowest mean values. The statistical analysis of the data shows that the metabolite status of the wheat grain from organic and mineralic farming did not differ in concentrations of 44 metabolites. This result indicates no impact or a small impact of the different farming systems. In consequence, we did not detect extreme differences in metabolite composition and quality of wheat grains.

Condensed stuff, probably 4 or 5 times the volume and weight of high strength fertilizers. So where do they get all that organic material used to fertilize organic crops?

One concept is to have most of the land (75%) in pasture or other low-intensity crops to feed to animals. Pasture " produces " nutrients from two sources: nitrogen fixation in the nodules of leguminous plants, and erosion of the subsoil. The animals produce a high value product, and also manure -- you put some of that back (maybe 50%) back on the pasture, and you put the rest on land that you use to grow nutrient-intensive crops, such as vegetables. To make this economical, you can't transport manure very far: this model doesn't work well for the kind of farms you see in the Central Valley of California, which can be miles on a side. Conventional agriculture is a form of mining. We can get away with it in the breadbaskets of the US, because we've got areas that have hundreds of feet of alluvium, but it just doesn't work in many parts of the world. Tropical soils, for instance, cycle organic matter rapidly: you can get a few years of crops after you cut rainforest, and then the land is shot. The same process happened in New England, except it took about 50 years to wreck the soil. Many parts of Europe depend on large-scale industrial composting programs to maintain the structure of soil that's been worked for centuries. It's astonishing to see how manure treatments transform soil. One of our neighbors put heavy loads of horse manure on pretty crappy clay; in a few years the soil was beautiful, as black as night, with an incredible ability to retain water. Unfortunately, he overdid it -- he had so much nitrogen in the soil that his tomato plants put all their energy into producing leaves, and none into producing fruits! Organic dairy is a big success story in the Northeast. Conventional farmers have to deal with all kinds of health problems caused by intensive confinement systems: mastisis, for instance, is an economic killer. It can be treated with drugs (expensive), but then you can't sell the milk until the drugs have worked out of the cow's system. Many farmers who switch to less intensive systems find that their production drops less than their costs do... They get more practical. If you're going to criticize organic, " free range " and other standards, it's that they require a number of practices which vary in value, and often allow many of the worst practices. The miracle of organic produce in California is the miracle of produce from California -- cheap labor. A farmer who uses more pasture and less grain might increase his profits -- but his costs go way up if he needs to use organic grain to be certified organic. " Deep Litter " systems produce quality eggs at lower cost than " free range " , and provide a much better life for hens than the battery systems, but there's no marketing label that consumers understand for them. All that said, the people in our other house have a flock of hens, and I'll tell you: eggs produced by free-range hens that mostly eat seeds and weeds (in the summer they get just enough imported grain to keep them coming back to the roost) taste immeasurably better than any eggs you can buy from the store, organic or not. You'll occasionally have one explode when you crack it, but that's a small price to pay. Quote Link to comment Share on other sites More sharing options...
Guest guest Posted October 21, 2006 Report Share Posted October 21, 2006 Thanks, , Recognize that heat animals turn all that into heat, with very little return. Regardless of the plan there is diminishing returns. I'm sure that all farmers recycle waste back into the ground of necessity. So we have to nourish the land with chemicals taken from other parts of the country. Land depleted by previous owners. Those fertilizer chemicals are the same that would be found in "organic" farmland, and careful analysis of the soil shows which chemicals must be added. If you don't move the chemical you move the product of that chemical. Taken to the limit, fertilizer is a necessity. Regards.
