New Meta-Analysis Identifies Three Significant Benefits Associated With Organically Grown Plant-Based Foods

There have been four progressively rigorous meta-analyses published since 2009 focusing on differences in the nutritional quality and safety of organic versus conventional food. The latest comes out July 15, 2014 in the British Journal of Nutrition (BJN). I was the sole American scientist on the mostly European research team that produced the BJN paper:
Higher antioxidant and lower cadmium concentrations and lower incidence of pesticide residues in organically grown crops: a systematic literature review and meta-analyses. Baranski, M., D. Srednicka-Tober, N. Volakakis, C. Seal, R. Sanderson, G. B. Stewart, C. Benbrook, B. Biavati, E. Markellou, C. Giotis, J. Gromadzka-Ostrowska, E. Rembiałkowska, K. Skwarło-Son, R. Tahvonen, D. Janovska, U. Niggli, P. Nicot and C. Leifert.

Problems triggered by the spread of glyphosate-resistant weeds in corn, soybean, and cotton country continue to worsen. An industry source recently projected that 70 million acres are now infested with one or more glyphosate-resistant weed. The presence of glyphosate-resistant weeds forces farmers to add additional herbicides to their control programs, and apply herbicides more often and/or at higher rates. Costs have risen $25 to over $75 per acre. Read more »

Avoiding pesticide exposure and risks remains the #1 reason most people choose organic food. This is not likely to change until there is convincing data that show only modest differences between the pesticide dietary risks associated with residues in and on organic food, compared to conventionally grown food.

An April 19, 2014 blog post by NPR correspondent Dan Charles discusses Wal-Mart’s plans to develop a substantial new line of organic food products that will be sold at a 25% lower price than other organic brands. The story quotes individuals who question whether Wal-Mart will be able to deliver on the idea without hurting farmers or cutting corners and sacrificing organic integrity, but they may be underestimating the benefits of Wal-Mart’s economy of scale.

In its December 20, 2013 issue, the journal Science identified cancer immunotherapy as the science breakthrough of the year. An editorial by the journal’s Editor-in-Chief Marcia McNutt explains the basis for the selection.
She notes that the war on cancer started 40 years ago and has had great success in treating some cancers, while others remain difficult to effectively combat. She also explains that as the baby boomer generation ages, cancer incidence, morbidity, and mortality will almost assuredly increase – hence the need for new tools. Read more »

Farm bills over the last forty years have shaped today’s agriculture systems and technology. They have done so by setting the “rules of the road” and defining or shaping research and investment priorities.
The new farm bill provides farmers, agribusiness, rural communities, and the food industry a more stable policy framework in which to make investment and planting decisions. But my sense is this farm bill could mark a historically significant inflection point. Farm bills since the 1970s have tried to become more market-driven, by lessening the impact of USDA farm programs on the choices made by farmers. Read more »

Dozens of studies, most of them conducted in Europe, have shown higher levels of health-promoting omega-3 fatty acids in organic milk compared to conventional milk, as well as lower levels of omega-6 fatty acids. The National Institutes of Health, in a factsheet on omega-3 fatty acids, reports that:
“Most American diets provide more than 10 times as much omega-6 than omega-3 fatty acids. There is general agreement that individuals should consume more omega-3 and less omega-6 fatty acids to promote good health.”

A growing number of Americans are learning that doctors don’t have miracle cures for all that ails us. The Institute for Health Metrics and Evaluation (IHME) at the University of Washington has just released chilling data on the burden of disease in America, the driving forces behind disease and ill health, and modifiable risk factors for contemporary health problems.

The finding of some Roundup Ready (RR) wheat plants in an eastern Oregon field must leave some PNW wheat growers feeling snakebit, since they decided a decade ago to oppose the commercialization of RR wheat until the technology is fully approved and accepted by consumers, both here and abroad. While this episode has disrupted trade flows and will undoubtedly increase wheat industry testing costs for the foreseeable future, some good could come from it if it triggers a fresh look at why skepticism and/or opposition to genetically engineered (GE) foods is growing in the U.S. The fate of many new GE crops hangs in the balance, including Simplot’s new potato technology that reduces levels of the known human carcinogen acrylamide.

A flurry of studies in recent years has reported that organic fruits and vegetables are, on average, more nutritious than conventional foods, while another flurry has reported little or no nutritional difference. While most review articles and meta-analysis conclude that Vitamin C, phenolic acids, antioxidant, and some mineral levels are typically higher in organically grown produce, the levels of some other nutrients are often higher in conventional food (e.g., protein, Vitamin A). Opinions vary widely on whether the typically small incremental differences in nutrients between organic and conventional foods are biologically meaningful.
