(Beyond Pesticides, July 15, 2014) More nutritional antioxidants, far fewer toxic pesticides; those are the results of a comprehensive meta-analysis on organic foods published yesterday in the British Journal of Nutrition.  Led by Carlo Leifort, Ph.D, at England’s Newcastle University, the analysis is a scientific rebuttal to a previous Stanford University review published in 2012, which found that there was little difference between the nutritional content of organic food over conventionally grown produce. Both studies found there to be fewer pesticides in organic products. While Stanford University’s review only looked at 200 studies, Dr. Leifert and his team of researchers expanded the scope of their meta-analysis to 343 studies, and also employed more robust analytic tools by analyzing the standardized mean differences of the data from the various studies. It shows very clearly how you grow your food has an impact,” said Dr. Leifert to The New York Times. “If you buy organic fruits and vegetables, you can be sure you have, on average, a higher amount of antioxidants at the same calorie level.” Antioxidants, compounds such as phenolic acids, flavanones, stilbenes, flavones, flavonols and anthocyanin, have been linked to lower risks of cancer and other diseases. For many, news […]

(Beyond Pesticides, February 8, 2013) A recent study conducted at the University of Granada, Spain and published in the Journal Environmental Research proposes a link between exposure to persistent organic pollutants (POPs) in food, air, and water and prevalence of type 2 diabetes in adults, regardless of age, gender, and body mass index. The paper concludes that people with higher concentrations of DDE, the break down product of DDT, are four times more likely to develop type 2 diabetes compared to other participants in the study. Increased rates of type 2 diabetes are also associated with exposure to beta-hexachlorocyclohexane, a break down product of the toxic chemical lindane, which in still allowed for use in agriculture and certain formulations of products used to treat lice and scabies. The study was carried out by analyzing the concentrations of specific POPs in adipose, or fat, tissue of 386 adults undergoing non-cancer-related surgery in Spain. According to one of the authors of the study, Juan Pedro Arrebola, “Human adipose tissue acts as an energy reservoir and has an important metabolic function. However, adipose tissue can store potentially harmful substances, such as POPs.”   The study found that as concentrations of POPs grows in […]

(Beyond Pesticides, July 5, 2011) Recent findings add to a growing body of evidence that persistent organic pollutants (POPs) might drive changes in the body that lead to diabetes, researchers say. A new study finds that environmental exposure to some POPs substantially increased risk of future type 2 diabetes in an elderly population. POPs are lipophilic (fat-loving) chemicals that accumulate mainly in adipose tissue and have recently been linked to type 2 diabetes. This current study, “Polychlorinated Biphenyls and Organochlorine Pesticides in Plasma Predict Development of Type 2 Diabetes in the Elderly: The Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS) Study,” sought to follow up on previous findings that had linked these chemicals with type 2 diabetes and was performed to evaluate prospective associations of type 2 diabetes with selected POPs among the elderly. The team recruited a group of 725 diabetes-free elderly adults in Sweden and took blood samples to measure their levels of the pollutants. Then, the researchers followed them for the next five years. Thirty-six of the study participants were diagnosed with type 2 diabetes over that time. Nineteen POPs (14 polychlorinated biphenyl [PCB] congeners, 3 organochlorine pesticides1 brominated diphenyl ether, and 1 dioxin) were […]

(Beyond Pesticides, September 28, 2010) A study published in the September 2010 issue of the journal Environmental Health Perspectives links low dose exposure to some persistent organic pollutants (POPs) to type 2 diabetes. The authors report that some POPs, including highly chlorinated PCBs, PBB153 and the organochlorine insecticides trans-nonachlor, oxychlordane and mirex, were associated with type 2 diabetes over an 18-year period, especially in obsese people. However, POPs did not show a traditional dose—response relationship with diabetes. Instead, POPs showed strong associations at relatively low exposures. The authors conclude that exposure to relatively low concentrations of certain POPs may play a role in the increased incidence of diabetes in the United States. The study, “Low Dose of Some Persistent Organic Pollutants Predicts Type 2 Diabetes: A Nested Case—Control Study,” examines participants who were diabetes free in 1987—1988. By 2005—2006, the 90 controls remained free of diabetes, whereas the 90 cases developed diabetes. Using serum collected in 1987—1988, the authors measured 8 organochlorine pesticides, 22 polychlorinated biphenyl congeners (PCBs), and 1 polybrominated biphenyl (PBB). They compare POP concentrations from Coronary Artery Risk Development in Young Adults (CARDIA) cohort and the National Health and Nutrition Examination Survey (NHANES) in 2003—2004. Persistent organic […]

(Beyond Pesticides, May 25, 2010) An analysis of 266 potential environmental contributors to type 2 diabetes published May 20, 2010 in the online edition of the journal PLoS ONE, links the disease to individuals who have higher levels of polychlorinated biphenyls (PCBs) and the pesticide heptachlor, as well a form of vitamin E found at high levels in soybean and corn oil, in their bodies compared to the general population. PCB was banned in 1979 and most uses of heptachlor were canceled between 1978 and 1989 (except for limited control of fire ants, which continues), but the compounds persist in the environment, especially near former industrial sites or contaminated soil. Environmentalists point to the fact that chemicals banned decades ago are still increasing people’s risk of disease, as a reason to take a precautionary approach when evaluating and registering chemicals. The analysis, led by Atul Butte, MD, PhD, assistant professor of medical informatics and pediatrics at the Stanford University School of Medicine, drew on data collected by the Centers for Disease Control and Prevention as part of the National Health and Nutrition Examination Survey (NHANES) to examine a wide range of environmental influences on type 2 diabetes. Dr. Butte conceived […]

(Beyond Pesticides, May 22, 2009) A balanced, organic diet – both before and during pregnancy – can significantly reduce a child’s likelihood of being overweight, obese or developing diabetes. That, according to a literature review of over 150 scientific studies assembled by The Organic Center (TOC), an organic industry research institute focused on the science of organic food and farming. The TOC review”That First Step: Organic Food and a Healthier Future” documents that exposure to pesticides during pregnancy increases the risk of premature birth, low-birth weight, neurological problems and diabetes. Outlining six ways in which a balanced organic diet can contribute to healthy development, the report also examines how enzymes found in organic foods can slow and even reverse aspects of the aging process. With the time between initial conception to the early years of development being the most critical in establishing lifelong health, a well-balanced diet rich in organic fruits and vegetables helps establish healthy food-taste preferences, promotes healthy patterns of cell division and largely eliminates exposures to approximately 180 pesticides known to increase the risk of developmental abnormalities. Furthermore, this combination of reducing pesticide exposure and consuming nutrient-dense organic foods can help people manage weight and prevent diabetes. […]

(Beyond Pesticides, November 11, 2008) Researchers at the Duke University School of Medicine have linked organophosphate pesticides to the epidemics of obesity and type 2 diabetes. The researchers specifically link neonatal low-dose parathion exposure in rats to disruption of glucose and fat homeostasis. The study, “Exposure of Neonatal Rats to Parathion Elicits Sex-Selective Reprogramming of Metabolism and Alters the Response to a High-Fat Diet in Adulthood,” was published in the November 2008 issue of Environmental Health Perspectives. It follows research by the National Institutes of Health (NIH) that links pesticide exposure to type 2 diabetes using epidemiological data from the Agricultural Health Study. Although most studies of organophosphates focus on their neurotoxicity, there is increasing evidence that these agents may also have a lasting impact on metabolic function. According to authors, obesity and consequent type II diabetes are rising at epidemic rates in the U.S. and many other countries around the world. Two of three U.S. adults are now classified as overweight. There are epidemiologic links between pesticide exposure and diabetes, and the same subpopulations that have the highest rates of obesity””inner-city, low-socioeconomic-status, agricultural populations””are also those that have greater exposure to organophosphates and other pesticides. The researchers chose parathion […]

(Beyond Pesticides, September 8, 2008) Inorganic arsenic may increase the risk of developing type 2 diabetes, according to a study published in the Journal of the American Medical Association by researchers at the Johns Hopkins Bloomberg School of Public Health. Common sources of inorganic arsenic exposure include dietary exposure, drinking water pollution, and contamination associated with arsenic wood preservatives such as sawdust, smoke, direct contact, and hazardous waste sites. The study found that individuals with diabetes have higher levels of arsenic in the urine compared to individuals without diabetes. Researchers examined randomly selected urine samples taken from 788 U.S. adults 20 years or older that participated in a 2003-2004 National Health and Nutrition Examination Survey. The results were adjusted for diabetes risk factors, including body mass index and for organic arsenic compounds found in seafood. “Our findings suggest that low levels of exposure to inorganic arsenic may play a role in diabetes,” said Ana Navas-Acien, MD, PhD, lead author of the study and assistant professor with the Bloomberg School’s Department of Environmental Health Sciences. “While prospective studies are needed to establish whether this association is causal, these findings add to the existing concerns about the long-term health consequences of low […]

(Beyond Pesticides, June 6, 2008) A recent study by the National Institutes of Health (NIH), including the National Institute of Environmental Health Sciences (NIEHS) and the National Cancer Institute (NCI), finds pesticide applicators with regular exposure to pesticides to be at a greater risk of type-2 diabetes. Published in the American Journal of Epidemiology (DOI: 10.1093/aje/kwn028), the study shows specific pesticides produce between a 20 and 200 percent increase in risk. Researchers looked at data from 31,787 pesticide applicators in North Carolina and Iowa over a period of five years. In that period, 1,171, or 3.7 percent, had developed diabetes, particularly for applicators in the highest category of lifetime days of use of any pesticide. “The results suggest that pesticides may be a contributing factor for diabetes along with known risk factors such as diabetes, lack of exercise and having a family history of diabetes,” said Dale Sandler, PhD, chief of the Epidemiology Branch of NIEHS. “Although the amount of diabetes explained by pesticides is small, these new findings may extend beyond the pesticide applicators in the study.” Freya Kamel, PhD, of NIEHS noted that “all of the seven pesticides” associated with an increased risk of type 2 diabetes are […]

(Beyond Pesticides, January 29, 2008) University of Cambridge scientists say there may be a link between persistent organic pollutants (POPs), including pesticides, and Type 2 Diabetes. The Cambridge scientists are advocating additional research into the little understood links between environmental pollution and adult onset diabetes. In the most recent edition of the journal Lancet, Oliver Jones, Ph.D., and Julian Griffin, Ph.D., highlight the need to research the possible link between persistent organic pollutants (POPs, a group which includes many pesticides) and insulin resistance, which can lead to adult onset diabetes. In their commentary, Dr. Jones and Dr. Griffin cite peer reviewed research including that of D. Lee, et al, which demonstrated a very strong relationship between the levels of POPs in blood, particularly organochlorine compounds, and the risk of type 2 diabetes. “Of course correlation does not automatically imply causation,” says Dr. Jones. “But if there is indeed a link, the health implications could be tremendous. At present there is very limited information. Research into adult onset diabetes currently focuses on genetics and obesity; there has been almost no consideration for the possible influence of environmental factors such as pollution.” Interestingly, in the Lee study an association between obesity and […]
