Charles “Chuck” Benbrook (born 1949) is an organic proponent, organic industry consultant and paid “expert witness” on pesticide and GMO-related lawsuits, Benbrook is trained as an agricultural economist. He has developed analytical systems he uses to quantify food quality and safety, and the impacts of agricultural technology and policy. He has re-analyzed government reports to suggest that there are high risks associated with GMOs, pesticide use and residue levels.
Benbrook was formerly the research director of The Organic Center, which is funded by the organic industry and is now officially part of the Organic Trade Association. His three year affiliation with the Center for Sustaining Agriculture and Natural Resources (CSANR) at Washington State University (WSU), which was funded entirely by organic industry contributions (see below), ended on May 15, 2015 when his contract was not extended. He is now no longer with CSANR.
A WSU administrator wrote in an August 2015 email that “he [Benbrook] is no longer affiliated with WSU”. However, Benbrook emailed the Genetic Literacy Project on August 20 claiming after his relationship with CSANR was severed, he retained the position of “adjunct” professor at the Department of Crops and Soils. However, that appears not be true. The department will not confirm his position and as of August 30, Benbrook’s current and former association with the university has been purged from the university’s databank.
Until recently, and after he was severed from WSU, Benbrook had represented himself as a “research professor.” He continues to be misrepresented as a “research professor” by reporters, such as by Carey Gillam at Reuters in an August 19 story on Benbrook’s New England Journal of Medicine co-authored commentary on GMOs, and on websites, including Wikipedia. Benbrook has publicly maintained, including in COI statements to the NEJM, that he has no conflicts of interests despite extensive documentation that his entire research efforts at WSU were 100 percent funded by the organic industry (not disclosed to NEJM, see below, Misrepresentations, for Benbrook’s misrepresentations about his employment situation and in Conflict of Interest representations to NEJM) and that he was and is a paid consultant for organic industry lobby groups and anti-GMO organizations.
The New York Times has released a trove of Benbrook’s emails secured in a FOIA request, documenting his organic industry funding and his close ties to anti-GMO activists and journalists, including Robyn O’Brien, who bills herself as the food world’s Erin Brokovich.
A separate FOIA led to the release of more of Benbrook’s emails, available here, which reaffirms his close ties to the industry that has bankrolled him for more than a decade. It includes his demands for financial support for ‘research on request.’ The emails also reveal the close ties of Benbrook and other anti-GMO campaigners, such as the GMO labeling lobbyists, with journalists unstintingly critical of GMOs, such as Michael Pollan and Mother Jones’ Tom Philpott, who appear to coordinate their article strategies and Internet presence with notable advocacy groups and quack alternative health providers.
Benbrook has claimed that the use of GMO crops has “backfired” and results in unsustainable massive increased pesticides (both insecticide and herbicide) use, that organic crops have equivalent or better yields than conventional and GMO counterparts and that organic foods are safer and more nutritious. He attacks and dismisses scientific research claims which conflict with his views as either tainted by industry funding (although his organic industry funded research is not held to similar scrutiny) or as making “rookie mistakes” as he characterized the Stanford University meta analysis of claims organic foods are no safer or nutritious than conventional counterparts.
In a 2010 speech quoted by the Economist, Benbrook asked a series of questions he claims should be used to determine whether or not biotechnology enhanced crops can be seen as a component of sustainable agriculture. He stated “It is hard to get to ‘Yes’, biotech and sustainable agriculture go together, with one neutral and three ‘No’ answers to the above questions.”
Benbrook had joined CSANR as a “research professor” (see reference for description) in August, 2012. He served as the leader of the CSANR program called Measure to Manage (M2M): Farm and Food Diagnostics for Sustainability and Health (M2M). The stated goal of M2M is to develop, refine, validate, and apply analytical systems quantifying the impacts of farming systems, technology, and policy on food nutritional quality, food safety, agricultural productivity, economic performance along food value chains, and on natural resources and the environment.
The M2M program was funded entirely by the organic industry with no funding support from any independent or university sources. According to the CSANR website, but since removed [but available here]:
Initial start-up funding for the M2M program have been provided by United Natural Foods, Whole Foods, Organic Valley/CROPP, and Stonyfield. In addition, the Clif Bar Family Foundation has provided a generous three-year, $250,000 grant to support the dissemination of analytical systems and results via the M2M website.
Work on calculating the embedded attributes of food products has been advanced by a $25,000 gift grant from Annie’s, a company working to quantify the benefits stemming from its purchase of a wide range of organic ingredients.
Benbrook’s best-known study, published in 2012, concluded that genetically modified foods have resulted in increased pesticide use, purportedly because weeds are developing resistance to glyphosate. The study was widely criticized in the mainstream science community because he did not take into account the fact that glyphosate is less toxic than the herbicides it has replaced, thus the net toxicity of herbicide use has decreased even as the total herbicide use increases. However, the Benbrook study is still widely circulated on anti-GMO websites as fact.
In addition, Graham Brookes of PG Economics has accused Benbrook of making subjective estimates of herbicide use because the data provided by the National Agricultural Statistics Service doesn’t distinguish between genetically modified and non-genetically modified crops. Brookes published a study whose conclusions contradicted those of Benbrook’s. In December 2013, Benbrook was the lead author of a study claiming that organic milk contained significantly higher levels of heart-healthy omega-3 fatty acids. The study was funded in part by the organic milk producer Organic Valley, and was sharply criticized for faulty assumptions and analysis. In July 2014, Benbrook was co-author of a meta-analysis of 343 studies examining the nutritional differences between organic and non-organic food. It concluded that organic food had higher levels of antioxidants and lower levels of cadmium than did conventional food.
Benbrook and co-author epidemiologist and pediatrician Philip Landrigan wrote a commentary, “GMOS, Herbicides and Public Health,” in the New England Journal of Medicine released August 19, 2015, calling for a global reconsideration of the safety of plant biotechnology due to their concerns over the impact of herbicides on public health. Landrigan, director of the Children’s Environmental Health Center at Mount Sinai Medical Center, has long maintained that “toxic chemicals” are silently damaging children around the world. The authors based their current argument upon the International Agency for Research on Cancer (IARC)’s controversial classification of glyphosate as a ‘probable’ carcinogen and of 2,4-D as a ‘possible’ carcinogen, along with the Environmental Protection Agency (EPA) decision to approve Enlist Duo, a herbicide comprising glyphosate and 2,4-D designed to be used with herbicide resistant, genetically engineered crops
Independent scientists are sharply criticizing the NEJM commentary. (See Genetic Experts News Service–GENeS–for more detailed analysis)
- Dr. Dave Stone, Associate Professor, Department of Environmental and Molecular Toxicology, Oregon State University
While it is important to pursue advances in how we assess and manage risk, it is equally important to avoid representations that use inflammatory language, are devoid of context and cause undue alarm. Unfortunately, the latter is the case with the recent commentary by Landrigan and Benbrook who cite Agent Orange, Monarch butterflies, and endocrine disruption to support labeling of genetically modified foods and distort the risk posed by plant biotechnology.
One of Landrigan and Benbrook’s central arguments is that the GMO landscape has changed as a result of the noted increase in herbicide applications to genetically modified (GM) crops. While this increase raises some key issues, such as weed resistance, the commentary suggests implications to consumers and public health that are unwarranted. Whether or not a pesticide is used in conventional or GM crops, the level of acceptable residue on a commodity, known as a tolerance, is set to protect us from harm. Year after year, residues in our food supply have been measured at trace levels that are far below what is required to result in clinically relevant effects.
- Dr. Jeff Wolt, Professor of Agronomy & Toxicology, Biosafety Institute for Genetically Modified Agricultural Products, Iowa State University
In their piece, Landrigan and Benbrook present a laundry list of familiar misperceptions of modern crop production. Through the lens of their perspective, the public gains a distorted view of the safety of biotechnology crops and pesticides; and of the immense contributions of agriculture to public health in the United States by assuring a safe and abundant food supply.
The IARC findings of glyphosate as a probable carcinogen and 2,4-D as a possible carcinogen signal the need for vigilance concerning their use, but say nothing regarding risk to human health. EPA and other regulatory authorities conduct a more holistic appraisal of pesticides which considers a wider array of toxicity information as well as exposure characterization to arrive at an understanding of risk of the chemicals under actual use conditions. It is these regulatory risk assessments that support the safe use of glyphosate and 2,4-D in agriculture. EPA shows appropriate vigilance in assuring safety of our food supply through periodic reappraisal of pesticides and is currently undertaking just such an assessment for glyphosate.
- Dr. Andrew Kniss, Associate Professor, Department of Plant Sciences, University of Wyoming
Dr. Landrigan and Dr. Benbrook cite glyphosate-resistant weeds as a primary reason why “fields must now be treated with multiple herbicides.” … [G]lyphosate-resistant weeds may certainly have increased the number of herbicides used per acre compared to 5 years ago, but the change has been relatively modest when compared to herbicide use before the adoption of GMO crops.
Dr. Landrigan and Dr. Benbrook also make several misleading statements, including that the Enlist Duo registration decision by EPA “failed to consider ecologic impact, such as effects on the monarch butterfly and other pollinators.” The EPA provides all relevant regulatory decision information on its website, including the environmental risk assessment documents. Just one of the risk assessment documents for Enlist Duo contains over 100 pages of ‘ecologic impact’ data and interpretation, including environmental fate, degradation, aquatic and terrestrial organism toxicity and exposure estimates. The EPA also explicitly addresses how Enlist Duo will affect pollinators on an FAQ page dedicated to the Enlist Duo registration.
Another misleading statement made by Dr. Landrigan and Dr. Benbrook is that the “risk assessment gave little consideration to potential health effects in infants and children, thus contravening federal pesticide law.” This claim was also addressed explicitly by EPA in the FAQ document. EPA concluded that after incorporating a 10X safety factor for children, and based on a “complete and very robust” data set, that the “risks were still acceptable for all age groups for all components of the assessment: dietary food and drinking water exposure, volatility, spray drift, residential, and aggregate assessment.
Misrepresentations on Conflict of Interest
Both Benbrook and Landrigan may have misrepresented themselves as to potential conflicts of interest in their New England Journal of Medicine article. Benbrook represented he was affiliated with Washington State University when he submitted his current article. But an official at WSU said he was no longer with the university as of May 16, 2015, before his NEJM article was finalized. Other misrepresentations may have come in response to NEJM questions about potential conflicts of interest:
Did you or your institution at any time receive payment or services from a third party (government, commercial, private foundation, etc.) for any aspect of the submitted work (including but not limited to grants, data monitoring board, study design, manuscript preparation, statistical analysis, etc.)?
100 percent of Benbrook’s funding at his institution was from organic industry commercial interests, which benefit from disparaging the safety of GMOs and pesticides.
Place a check in the appropriate boxes in the table to indicate whether you have financial relationships (regardless of amount of compensation) with entities as described in the instructions. Use one line for each entity; add as many lines as you need by clicking the “Add +” box. You should report relationships that were present during the 36 months prior to publication.
Benbrook is a consultant to commercial interests, including Whole Foods Market and litigators with current cases pending against GMO and pesticide companies, which claim and profit from claims that GMOs and pesticides are unsafe
Are there other relationships or activities that readers could perceive to have influenced, or that give the appearance of potentially influencing, what you wrote in the submitted work?
Both Benbrook and Landrigan are board members, advisors and/or paid consultants to numerous organic activist groups and organizations.
Benbrook amended his conflict of interest answers on August 27, but they continue to be inaccurate. He continues to state that he had no “financial relationships” with organizations that might have a vested interest in his work [e.g. defined by NEJM as: “financial relationships with entities in the bio-medical arena that could be perceived to influence, or that give the appearance of potentially influencing, what you wrote in the submitted work. You should disclose interactions with ANY entity that could be considered broadly relevant to the work”.
Benbrook was and is a paid consultant to the organic industry, including Whole Foods, and 100% of the funds that supported his since severed project at Washington Sate University were supplied by the organic industry–according to the disclosure on the WSU website (since removed by WSU but displayed above and available here). Note that NEJM states that submitting authors are required to report any “relationships or activities that readers could perceive to have influenced, or that give the appearance of potentially influencing, what you wrote in the submitted work.”
Charles Benbrook joined CSANR as a “research professor” (see reference for description) in August, 2012. He serves as the leader of the new solely organic industry funded CSANR program called Measure to Manage (M2M): Farm and Food Diagnostics for Sustainability and Health (M2M). The stated goal of M2M is to develop, refine, validate, and apply analytical systems quantifying the impacts of farming systems, technology, and policy on food nutritional quality, food safety, agricultural productivity, economic performance along food value chains, and on natural resources and the environment.
Benbrook has a PhD in agricultural economics from the University of Wisconsin-Madison and an undergraduate degree from Harvard University. Until May, he held an adjunct faculty position in the Crop and Soil Sciences Department, Washington State University. His affiliations and publications all have a decidedly anti-biotechnology, pro-organic slant. In a 2009 interview with the Economist, Benbrook asked a series of questions he claims should be used to determine whether or not biotechnology enhanced crops can be seen as a component of sustainable agriculture. He stated “It is hard to get to “Yes”, biotech and sustainable agriculture go together, with one neutral and three “No” answers to the above questions.”
Benbrook spent the first 18 years of his career working in Washington, D.C., first working for the Executive Office of the President (1979-1980), then as the Executive Director for a U.S. House of Representatives agricultural subcommittee (1981-1983). He was the ED of the National Academy of Sciences Board on Agriculture from 1984-1990, and has run his own consulting firm since 1991.
He moved to the west in 1997, and served as the Chief Scientist for The Organic Center from 2004 through June of 2012. He has participated as an expert witness in several lawsuits involving pesticides and agricultural biotechnology. Chuck Benbrook earned a B.A. degree in economics from Harvard University in 1971, and M.A. and PhD degrees in agricultural economics from the University of Wisconsin-Madison in 1979/1980.

Washington State University, Center for Sustainable Agriculture and Natural Resources (CSANR)
“Research” professor (August 16, 2012 – May 15, 2015) — Benbrook’s name has been scrubbed from the “people” section of the CSANR website. His name does not appear in any WSU offered course listings. CSANR officials say they are still in the process of transitioning his website and other resources, which by agreement must be completed by August 31.
Previously, as a “research professor”, Benbrook ran the M2M program within WSU CSANR group. His responsibilities were two fold: To boost faculty cadre actively working on organic agriculture at WSU and to establish a peer reviewed research framework for evaluating sustainability metrics, a rapidly growing driver in the organic marketplace. Funding for Benbrook’s M2M program did not come from the University but was provided by a set of organic industry donors with the intent that Benbrook would establish a base from which he could compete for competitive funding–that his work would stand up to scientific review. In the three years, all funding for his salary and program came from direct industry support provided by United Natural Foods, Whole Foods, Organic Valley/CROPP, and Stonyfield. In addition, the Clif Bar Family Foundation and Annie’s Organic.
Benbrook’s three person staff included Donald R. Davis, PhD (part time), a retired former academic with the University of Texas and research consultant at an alternative medical clinic in Kansas; he was also a frequent speaker at alternative health and organic conferences. And, Nicholas Potter, MS, who works on “data visualization” for web settings on pesticide risks.. Karie Knoke, BS, a former computer consultant for a hearing aid company and health and personal care worker promoting “off the grid” yurt dwellings and natural living from Sand Point, Idaho (Benbrook’s former hometown), provides data entry and interpretation support. Knote is a former fisherwoman from Alaska who has done pesticide research for Consumers Union and advocated for “energy healing, astrology and the primitive arts.”
Benbrook’s center at WSU appeared to be “virtual” as neither he nor any of his listed staff lived within 200 miles of the University campus and CSANR offices. The official mailing address for M2M is Benbrook’s personal residence in Enterprise, Oregon more than 375 miles from the CSANR offices and University of Washington campus. Computer expert Knote lives “off the grid” near San Point Idaho (220 miles from M2M and 365 miles from WSU campus), data visualization staffer Nicholas Potter resides in Spokane (290 miles from campus and 165 miles from the listed M2M offices). And Davis resides near Austin, Texas (1,800-2,100 miles from the respective locations).
As part of his affiliation with The Organic Center (see below), also an industry funded and led organization now formally part of the Organic Trade Association, Benbrook directed tens of thousands of dollars in donations to Washington State University to support the development of organic farming research. Pacific Natural Foods, a leading organic and anti-GMO food marketer, also provided a $5 million grant to Washington State University in 2012 to support the creation of Benbrook’s organic research center. No unniversity funds are publicly reported as directly supporting Benbrook’s M2M program.
The Organic Center (TOC)
Benbrook served as “chief scientist” for TOC from 2006-2012. TOC was an independent NGO laregly funded by the organic industry until 2011 when it formally merged with the Organic Trade Association. Benbrook led research to support organic agriculture via denigrating conventional agriculture, specifically developing research and public relations campaigns attacking the efficacy and safety of modern crop protection (pesticides) and plant biotechnology (GMOs).
Benbrook Consultant Services/AgBiotech-Info.net
From 1990 to present, Benbrook has served as a scientific and technical consultant to the organic food industry and organic-supporting advocacy groups. In this capacity he has also served as an expert witness for litigators (including The Center for Food Safety in pesticide and biotechnology-related cases suing the federal government and ag biotech companies. He also owned and ran the website and listserv Biotech Info Net (no longer active). Benbrook’s clients include national consumer and environmental groups, international organizations, companies, federal and state government agencies, trade associations, and academic research organizations.
Most recently, Benbrook was a consultant to Whole Foods, which in a controversial decision launched a “Responsibly Grown” ratings system. It allowed the grocer to pick and choose within a list of agrichemicals it considered harmful and less harmful. Some organic products were rated as harmful under this system and some non-organic produce treated with certain chemicals, were listed as “best,” in many cases rating above certified organic fruits and vegetables. It has created a furor among organic purists.
National Research Council
From 1984 to 1990 Benbrook served as executive director for the Board of Agriculture. Benbrook claims he left this position because of his role directing and opposing the findings of a study on children and pesticides. However, according to a 1993 letter from National Academy of Sciences president Frank Press to documentary filmmaker Bill Moyers, Benbrook was asked to resign from this position following repeated violations of NAS guidelines regarding non-biased, non-partisan and professional science staff statements, well before the child pesticide study was completed. Press wrote:
- The editing of the documentary will lead viewers to the erroneous conclusion that the employment of Charles Benbrook at the NAS-NRC was terminated as a result of his role as the director of the study on children and pesticides. This simply was not the case. The facts are that Mr. Benbrook was warned both orally and in writing on multiple occasions, long before the Landrigan committee began writing its report, that his public comments in speeches, testimony, and in print, on studies already completed and on other matters were inappropriate to his role as a member of the NRC professional staff. Indeed, in a letter of warning that I wrote to Mr. Benbrook on November 14, 1989, I stated that “the NRC corporate entity must be non-partisan, and professional staff statements should reflect views that have resulted from our process of balanced committee analysis and careful review. Your actions… do not conform to that process and you have been frequently advised to be more careful.” Mr. Benbrook chose subsequently to ignore the specific guidance contained in the letter and, after yet another such incident regarding a public statement he made on an unrelated matter, he was asked to resign one year later, when the children and pesticides study still was in an early stage of development.
U.S. House Agriculture Committee
From 1981 t0 1984 Benbrook served as a sub-committee staff person to U.S. House of Representatives George E. Brown and Congressman Jim Weaver of Oregon.
Office of the President, Council of Environmental Quality
From December 1979 to March 1981 Benbrook served as an agricultural policy analyst.
Benbrook actively advocates that GMOs can cause known allergies or post other safety challenges and pesticides are unsafe, unjust and unsustainable. He claims organic farming is a safer, healthier and superior system.
Benbrook has participated in numerous organic industry advocacy initiatives, conferences and petition campaigns opposing GMOs with groups including the Center for Food Safety, Friends of the Earth and the Pesticide Action Network. Benbrook is a member of Bioneers and affiliated via his consulting with Consumers Union; other advocacy-consulting engagements include:
- Western Organization of Resource Councils, co-author and research source for anti-biotechnology publications
- Greenpeace – research consultant/source, event speaker for biotechnology related publications and events
- Center for Food Safety/Andrew Kimbrell – research consultant/ source for biotechnology related litigation and publications
- International Center for Technology Assessment/ Mark Ritchie – research consultant/ source for biotechnology related lobbying and publications
- Just Label It campaign (Organic Voices 501c4 lobbying arm of organic companies)
- “Biotechnology is not a system of farming. It reflects no specific philosophy nor is it guided by a set of principles or performance criteria. It is a bag of tools than can be used for good or evil, and lots in between.” The Economist, November 2009.
- “Clearly the biotech industry will ultimately be held responsible for negative impacts of their technology. It may take lawsuits or class action lawsuits. The system has to change; it is unjust and not sustainable,” The Organic & Non-GMO Report, February 2011.
- “There have been dramatic changes in the transgenic composition of GE corn and soybeans over the last five years, coupled with a substantial increase in reliance on pesticides and Bt toxins. Compared to the first five years of commercial use (1996-2000), today’s GE corn and soybeans in the U.S. require:
- About twice as much herbicide per acre, with glyphosate/Roundup accounting for essentially all the growth;
- In corn, two to six Bt toxins to deal with European corn borer and the corn rootworm complex;
- Delayed release, systemic seed treatments including at least two insecticides and two fungicides, one of which is a nicotinyl implicated in honey bee Colony Collapse Disorder;
- A return to corn soil insecticide use as a component of Bt-gene, resistance-management programs (eroding a portion of the reduction in insecticide use brought about by Bt corn);
- Significant and historically unprecedented increases in fungicide use on corn (11 percent of crop acres were treated in latest USDA pesticide use survey 2010, no more than 1 percent was treated previously); and
- Approval and commercial planting in the U.S. of the first GE crop that will be consumed in significant quantities by humans in a largely unprocessed form – Bt and RR sweetcorn.” Charles Benbrook – GE Crop Risk Assessment Challenges: An Overview, Food Safety News, 6 May 2013
- See “forced resignation” citation regarding Benbrook’s termination from the National Research Council at the NAS, noting, “Mr. Benbrook was warned both orally and in writing on multiple occassions that his public comments, in speeches, testimony and in prent on studies already completed and on other matters were inappropriate to his role as a member of the NRC professional staff.”
Regarding Benbrook’s 2012 report on GMO and pesticide impact use in the United States:
- Dr. Alan McHughen (UC Riverside) and researchers Graham Brookes and Janet Carpenter documented various “inaccurate claims”, “inaccuracies and biased assumptions” and “misleading use of official data” they describe as Benbrook’s justification for using his “own interpretations and assumptions” for over-estimating pesticide use on GMO crops while underestimating use on conventional and organic crops and that Benbrook produced no references from reputable science journal published research to support his allegations of human health risks from GMO Bt crops.
- “The data on which Benbrook relied do not, in fact, support his conclusions. His work exemplifies the observation of biologist James F. Bonner, who once said about the research results of a competitor that did not agree with his own, “There are a thousand ways to do an experiment wrong.” Benbrook has found many of those ways, and his recent article serves as a case study of how to bend the data to support a preordained (and insupportable) conclusion.” and “While at his previous position at the U.S. Organic Center, which is ideologically and intractably (and irrationally) opposed to genetic engineering, Benbrook authored many other papers with similar claims about genetic engineering. None were published in reputable peer-reviewed journals and when independently assessed, they were invariably exposed as being misleading and inaccurate. From his new perch in academia, Benbrook has sought credibility by managing to get one of his ideological screeds into a peer-reviewed journal.” – Graham Brookes is an agricultural economist with the UK-based consultancy business PG Economics and author of 13 peer reviewed papers on the economic and environmental impact of genetically engineered crops. With, Henry I. Miller, a physician and molecular biologist, is the Robert Wesson Fellow in Scientific Philosophy and Public Policy at Stanford University’s Hoover Institution.
Regarding Benbrook’s Organic Center (OC) 2009 reports on GMO, pesticide use and seed choice in the United States:
- PG Economics: “The OC’s assessment of the impact of biotech herbicide tolerant traits (HT) is disappointingly inaccurate, misleading and fails to acknowledge several of the benefits US farmers and citizens have derived from use of the technology… Its conclusions are highly dependent upon the assumptions used, and perceptions of the author, as to how seed markets work and farmers behave. We consider that the mainstream US market evidence does not support the OC report conclusions.” PG Economics briefing note 4 December 2009, “The Magnitude and impacts of the biotech and organic seed price premium: US Organic Center report assessment by PG Economics” & PG Economics Briefing note: 19 November 2009, “Impact of genetically engineered crops on pesticide use: US Organic Center report evaluation by PG Economics.
Regarding Benbrook’s 2008 “Nutritional Superiority of Organic Foods” report:
- Joseph D. Rosen, professor emeritus Rutgers University’s School of Environmental and Biological Sciences, “My own review of the study, however, shows it to be riddled with flaws and its conclusions unsupported…My own review of this study showed it to be neither rigorous nor able to support the 25 percent “more nutritious” claim. The study suffers from numerous defects, such as inclusion of publications that were not peer-reviewed, studies where the differences in nutrient content between organic and conventional produce were not statistically significant, and publications with insufficient information for statistical analysis. In some cases the study failed to include results favorable to conventional farming while including data from organically grown food that is unavailable to consumers and/or inedible and thus arguably irrelevant.”
Benbrook conflicts of interest:
- “Charles Benbrook is an employee of the Organic Center, so it should not be expected that he has no financial interest in the promotion of organic food sales. Industrial donors to the Organic Center with contributions of at least $50,000 include Aurora Organic Dairy, Horizon Organic, Organic Valley Cooperative, Silk Soy, Stonyfield Farm, White Wave, and Whole Foods Market. Individual donors of at least $50,000 include Walter Robb and John Mackey, co-presidents of Whole Foods; Eugene Kahn, a General Mills vice president and founder of their subsidiary, Cascadian Farm; Mark Retzloff, founder of Horizon Dairies; and Steve Demos, president of combined operations for White Wave, Horizon Organics, and Dean Foods.”
