(Beyond Pesticides, March 4, 2024) With 14.7 million children and adolescents in the U.S. recognized as obese by the Centers for Disease Control and Prevention (CDC) and the established connection with endocrine disrupting contaminants, including many pesticides, Beyond Pesticides is calling on federal food assistance programs to go organic. The problem of childhood obesity is higher in people of color and, as a result, is an environmental justice issue. According to CDC, the prevalence of childhood obesity is “26.2% among Hispanic children, 24.8% among non-Hispanic Black children, 16.6% among non-Hispanic White children, and 9.0% among non-Hispanic Asian children.” While childhood obesity is recognized as a serious problem, the National School Lunch Program of the U.S. Department of Agriculture (USDA)—although improved by the Healthy, Hunger-Free Kids Act of 2010—still provides lunches laced with obesogenic pesticides. To take meaningful steps against childhood obesity, school lunches must be organic. The program served 4.9 billion meals in fiscal year 2022 in over 100,000 public and nonprofit schools, grades Pre-Kindergarten-12. Contrary to popular opinion, the blame for the obesity epidemic cannot be attributed solely to diet and exercise broadly, but relates directly to pesticide and toxic chemical exposures, including residues in food, that may lead […]

(Beyond Pesticides, October 18, 2023) A meta-analysis published in Toxics finds an association between exposure to organophosphate pesticides (OPs) and respiratory diseases and diabetes mellitus (DM). Specifically, wheezing and asthma are the most common respiratory manifestations of OP exposure, while fluctuation in weight and fat/glucose levels are the most common metabolically related manifestations. Organophosphorus pesticides have a wide range of biological uses—from insecticides to flame retardants—that make these chemicals ubiquitous, significantly contributing to ecosystem contamination. Thus, OP compounds have a global distribution, with evaporation and precipitation facilitating long-range atmospheric transport, deposition, and bioaccumulation of hazardous chemicals in the environment. Many studies show OPs are highly toxic, and residues are consistently present in human and animal urine, blood, tissues, and milk. Considering 90 percent of Americans have at least one pesticide compound in their body, primarily stemming from dietary exposure, including food and drinking water, advocates maintain that current restrictions on their use must adequately detect and assess total chemical contaminants.  This study investigated the effects and possible mechanisms involved in adverse health outcomes associated with OP exposure. Reviewing studies from Web of Science, PubMed, Embase, OVID, and the Cochrane Library, researchers systematically searched for articles on OP exposure and respiratory, DM, and cardiovascular disease (CVD) outcomes until 2022. […]

(Beyond Pesticides, September 27, 2023) A study published in Pesticide Biochemistry and Physiology finds organophosphate (OP), organochlorine (OC), and pyrethroid (PYR) pesticides have links to insulin resistance (IR) associated with metabolic disorders like diabetes, obesity, chronic kidney disease (CKD), and hypertension. Metabolic disorders are among the leading causes of morbidity and mortality, with over 11 percent (>37 million) of individuals in the U.S. having diabetes, and cases are growing by millions annually. Additionally, there is a rise in metabolic disorders among young people. Studies even find low levels of pesticide exposure during pregnancy or childhood cause adverse health effects, including metabolic disorders tied to gut microbiome disruption (dysbiosis). With increasing rates of diabetes and obesity, the two most prominent metabolic diseases in the study, cases among the global population, studies like these highlight the importance of evaluating how chemical contaminants deregulate normal bodily function through metabolic changes.  To investigate the association between pesticide exposure and insulin-related metabolic disorders in humans, researchers searched the PubMed database for articles, performing a systematic review. The study notes, “IR is defined as a pathological state in which a higher-than-normal level of insulin is required to produce the optimal response in cells.” The search generated 4,051 articles related to the topic. However, after excluding duplicates and […]

(Beyond Pesticides, August 25, 2022) A study published in World Journal of Pediatrics finds an association between antibiotic and neonicotinoid (neonic) exposure and onset of pediatric (childhood) type 1 diabetes (T1D) through effects on the gut microbiome. Individuals with type 1 diabetes are at higher risk of other autoimmune disorders, including thyroid and celiac disease. Ample evidence demonstrates environmental contaminants like pesticides and antibiotics negatively affect human mouth and gut microbes. Through the gut biome, pesticide exposure can enhance or exacerbate the adverse effects of additional environmental toxicants on the body. Moreover, studies find low levels of pesticide exposure during pregnancy or childhood cause adverse health effects from metabolic/immune disorders to mental and physical disabilities. Children are particularly vulnerable to the impacts of pesticide exposure as their developing bodies cannot adequately combat exposure effects. Although studies show how chemical exposures affect overall human health, more research is now questioning how these toxic chemicals influence gut health and subsequent occurrence of diseases. In children, gut microbiome disruption, or gut dysbiosis, has significant associations with type 1 diabetes development, and disruption of gut microbiota plays a role in type 2 diabetes development. Over 11 percent (>37 million) of individuals in the U.S. have diabetes, and cases are growing by millions annually. With increasing rates of type 1 and […]

(Beyond Pesticides, June 16, 2022) Farmed salmon serves as an inferior food source, accumulating more toxic chemicals in fatty tissue with fewer healthy nutrient properties based on a study from the University of Bergen, Norway and Alternative Medicine Review. However, the issue of toxic chemical contamination in fish dates back decades with investigations demonstrating high levels of persistent organic pollutants (POPs), including polybrominated diphenyl ethers (PBDEs) flame retardants restricted or banned in the U.S. and U.K., polychlorinated biphenyl (PCBs), dioxin (a by-product of pesticide manufacturing), and ethoxyquin (a pesticide preservative in fish feed). The aquaculture industry (e.g., farmed seafood/fish) repeatedly faces sustainability issues, failing to adhere to environmental regulations and threatening marine health. Extensive use of pesticides in local marine ecosystems has induced coastal habitat loss and increased genetic and health risks to wild marine populations. Moreover, insecticides used to kill salmon parasites (e.g., fish lice) has led to widespread disease persistence and pest resistance. Marine species biodiversity is rapidly declining due to overfishing, global warming, pathogens, and pollution. Thus, further biodiversity loss can change aquatic and terrestrial ecosystem functions and reduce ecosystem services. Food analysis results find the consumption of farmed salmon fillets contributes to higher rates of metabolic disorders, including diabetes and obesity. These farmed salmon also contain levels […]

The organic solutions to problems highlighted in the latest issue of Pesticides and You—based on the importance of healthy ecosystems and public health protection—are within reach, and the data creates an imperative for action now that phases out pesticides within a decade, while ensuring food productivity, resilient land management, and safe food, air, and water. (Beyond Pesticides, April 15, 2022) The current issue of Pesticides and You, RETROSPECTIVE 2021: A Call to Urgent Action, is a look at a year of science, policy, and advocacy that informs both the existential problems that the U.S. and the world are facing due to toxic pesticide dependency, and solutions that can be adopted now. The information in this issue captures the body of science that empowers action at the local, state, and federal level, and provides a framework for challenging toxic pesticide use and putting alternatives in place. The issue finds that 2021 was a pivotal year in both defining the problem and advancing the solution. This year in review is divided into nine sections that provide an accounting of scientific findings documenting serious pesticide-induced health and environmental effects, disproportionate risk to people of color and those with preexisting conditions, regulatory failures, at the same time […]

(Beyond Pesticides, April 15, 2021) Gestational (during pregnancy) and childhood exposure to per- and polyfluoroalkyl substances (PFAS) increase cardiometabolic risk, or the risk of heart diseases and metabolic disorders, later in life, according to a Brown University study published in Environment International. Past studies associate exposure to chemical pollutants with increased susceptibility to adverse health effects during critical fetal and childhood developmental periods. Some of these health effects are cardiometabolic risk factors, including obesity, insulin issues, abnormal blood pressure, that increase the risk of developing cardiovascular disease (CVD) and metabolic disorders (e.g., type 2 diabetes). PFAS are of particular concern as these endocrine-disrupting chemicals are common in non-stick cookware, cleaning/personal care products, food packaging, and other consumer products. They are now being found in pesticide products. Because of their ubiquitous use in many products, studies report that PFAS compounds are detectable in infants, children, and pregnant women. Furthermore, pregnant women can readily transfer compounds to the developing fetus through the placenta. Cardiovascular disease and diabetes are among the leading causes of death globally. Additionally, heart conditions are one leading cause of disability in the U.S., as research demonstrates environmental pollutant exposure can increase the risk of developing cardiovascular disease, including stroke, heart attack, heart failure, atrial fibrillation, and cardiac […]

(Beyond Pesticides, November 24, 2020) Reinforcing a body of scientific evidence, a new study finds that eating organic food lowers one’s risk of developing type 2 diabetes. With 1 in 10 (34 million) Americans afflicted with type 2 diabetes, and 1 in 3 (88 million) with prediabetes, new strategies focused on prevention are urgently needed. The results of the study, published by a team of French and American researchers in the International Journal of Behavioral Nutrition and Physical Activity, reinforce the triple bottom line (profit, people, and the environment) benefits of organic food for public health, the environment, and the wider economy. Scientists used data from NutriNet-Santé, a massive study including over 170,000 participants (averaging 52 years old) that regularly respond to questions concerning lifestyle, dietary intake, body type, physical activity, and health status. Roughly 33,000 NutriNet-Santé participants completed food frequency questionnaire regarding how often they consumed organic food. After four years, 293 surveyed individuals had been diagnosed with type 2 diabetes. Researchers then looked at how organic food consumption affected the risk of developing the disease, adjusting for body mass index, gender, family history of diabetes, physical activity, education, economic status, occupation, smoking, and alcohol consumption. Higher organic food […]

(Beyond Pesticides, December 17, 2019) South Asian immigrants to the U.S. may be at increased risk of diabetes due to prior exposure to high levels of DDT, research published by the University of California Davis earlier this month indicates. The study highlights a blind spot for health care in the U.S., researchers say. “Our findings evoke a new interpretation of Rachel Carson’s famous book Silent Spring, in that the high DDT exposures of South Asian immigrants in the U.S. currently fall on deaf ears in the U.S.,” said lead author Michele La Merrill, PhD an associate professor in the UC Davis Department of Environmental Toxicology. “Although DDT remains in use in other nations and migration globalizes these exposures, people in the U.S. often mistakenly regard DDT exposure as no longer relevant to our society due to its ban in this country nearly 50 years ago.” When compared to other race and ethnic groups, South Asian immigrants (individuals from India, Pakistan, Bangladesh, Nepal, Sri Lanka, and Bhutan), are at greater risk of developing diabetes, even when adjusting for potential confounders such as age and obesity. Authors of the study hypothesized that this was a result of past exposure to high levels […]

(Beyond Pesticides, September, 2017) A recently released report, Gallup-Sharecare State of Well-Being: The Face of Diabetes in the United States, looks at high diabetes rates across various U.S. demographic groups, including those in farming. People working in the transportation sector registered the highest incidence of diagnosed diabetes at 10.6%. But those working as farmers and fishermen came in second, with 8.5% reporting a diagnosis of the disease. Based on a self-reporting survey, The Face of Diabetes in the United States did not differentiate between Type 1 diabetes (which typically manifests in childhood or young adulthood) and Type 2 diabetes (which commonly emerges in adulthood). It did, however, consider lifestyle risk factors that can influence development of each form of the disease. The “farmer and fisher” folks placed more-or-less in the mid-range among all occupations vis-à-vis several of the lifestyle factors that can impact development of the disease (smoking, diet, and obesity), and a bit higher in alcohol consumption, but in fact, reported more exercise than any other category of worker. These data points would seem to suggest that farmers would be at less risk than those in some other occupational categories. For instance, those working in “installation and repair” reported […]

(Beyond Pesticides, January 25, 2017) A study conducted at the University of Buffalo recently revealed a connection between two common insecticides and an increased risk for certain metabolic diseases, including diabetes. Researchers found that by binding to and disrupting melatonin receptors that control numerous physiological functions, chemicals such as insecticides can affect melatonin levels, creating a higher risk for metabolic diseases to develop. The study, Carbamate Insecticides Target Human Melatonin Receptors, was published in Chemical Research in Toxicology and was funded by a grant from the National Institute of Environmental Health Sciences, which is part of the National Institutes of Health. The implicated chemicals in this research, carbaryl and carbofuran, are notoriously dangerous carbamate insecticides. Carbamates share structural characteristics and an ability to inhibit acetylcholinesterase (AChE), an enzyme important for the transmission of nerve impulses. When AChE is inhibited, acetylcholine accumulates leading to overstimulation of neurotransmitters, resulting in muscle weakness, confusion, and paralysis, among other symptoms. Carbaryl is said by EPA to be “one of the most widely applied insecticides in the U.S.,” since use began in 1959, with 10-15 million pounds used annually. It is a broad-spectrum insecticide used on a variety of crops, in forestry and on ornamentals, in […]

(Beyond Pesticides, October 20, 2016) Researchers at the University of Western Australia (UWA) and Murdoch University recently released a study whose findings show that levels of pesticides in breast milk have dropped significantly over the past forty years, though some major concerns remain. Published in the international journal Chemosphere, the research shows a 42-fold decrease in levels of pesticides detected in breast milk, and ties the reduction to government efforts to prohibit persistent organic pollutants (POPs) in Australia, which has lead to decreased exposure over time. Led by UWA’s internationally renowned human lactation researcher Emeritus Professor Peter Hartmann, Dr. Donna Geddes and Murdoch’s Associate Professor Robert Trengove, the study is a testament to the positive impact banning pesticides can have on the health of individuals, especially vulnerable populations like infants, but also shows that there is a long way to go before our bodies are void of any bioaccumulated toxic residues. Researchers often study breast milk because it can bioconcentrate, or accumulate, persistent organic pollutants (POPs). Multiple studies on breast milk have been performed throughout the years, many of them confirming the fact that common toxic chemicals, such as glyphosate and triclosan, build up in our bodies over time. Most […]

(Beyond Pesticides, September 14, 2016) According to a recent study by the U.S. Geological Survey (USGS), high concentrations of dioxins and furans have been detected in tree swallow eggs collected near several sites around the Great Lakes. Other chemicals detected include polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs), which were at background levels. The study is part of efforts to clean up a toxic chemical legacy around the Great Lakes, and the researchers believe their results are critical to regulators to assess “bird or animal deformity or reproductive problems” The study, “Concentrations and spatial patterns of organic contaminants in tree swallow (Tachycineta bicolor) eggs at United States and binational Great Lakes Areas of Concern, 2010—2015,” used tree swallows to quantify current exposure to organic contaminants across all five Great Lakes including 59 sites within 27  Areas of Concern (AOCs)  and 10 nearby  locations. The Great Lakes Areas of Concern refers to a U.S.-Canada  Great Lakes Water Quality Agreement  (Annex 1 of the 2012 Protocol) that  defines AOCs as “geographic areas designated by the Parties where significant  impairment of beneficial uses  has occurred as a result of human activities at the local level.” An AOC is a location that has […]

(Beyond Pesticides, August 24, 2016) Researchers at Drexel University report that higher levels of some organochlorine compounds during pregnancy are associated with autism spectrum disorder (ASD) and intellectual disability (ID). The organochlorine compounds under study have long been banned in the U.S., and include pesticides like DDT, underscoring how pervasive and persistent these chemicals are, and their continued impact on human health. The research is reported in the study  Polychlorinated Biphenyl and Organochlorine Pesticide Concentrations in Maternal Mid-Pregnancy Serum Sam ples: Association with Autism Spectrum Disorder and Intellectual Disability,  which examines whether prenatal exposure to polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) influences offspring risk of ASD and intellectual disability without autism (ID). According to the research, children born after being exposed to the highest levels of organochlorines during their mother’s pregnancy are roughly 80 percent more likely to be diagnosed with autism when compared to individuals with the very lowest levels of these chemicals. The team looked at a population sample of 1,144 children born in Southern California between 2000 and 2003. Data was accrued from mothers who had enrolled in California’s Expanded Alphafetoprotein Prenatal Screening Program, which is dedicated to detecting birth defects during pregnancy. Participants’ children were […]

(Beyond Pesticides, August 10, 2016) In a letter, submitted by the Soil Association, leading bread producers and supermarkets in the United Kingdom (UK) are being urged to cease stocking and selling bread products that  contain traces of the herbicide glyphosate. Glyphosate, the active ingredient in Monsanto’s Roundup, has been classified as a probable human carcinogen by the World Health Organization (WHO) and is linked to numerous other environmental and human health concerns. Glyphosate residues have already been detected in bread, beer, and wine. The Soil Association, a UK organization that campaigns for healthy, humane and sustainable food, farming and land use, is concerned that glyphosate is used on crops immediately before harvest, and subsequently makes its way into food. According to the letter and a spokesperson for the group, “Using glyphosate, and glyphosate-based products, as a pre-harvest treatment is fundamentally wrong, and we are calling for an end to it with our campaign.  Wheat harvest will start in the next few weeks, and we are asking bread companies to act now and put a stop to glyphosate as a pre-harvest desiccant in their supply chains. The EU has just advised glyphosate use as a pre-harvest spray on food crops should […]

(Beyond Pesticides, September 22, 2015) A meta-analysis presented at the annual meeting of the European Association for the Study of Diabetes in Sweden concludes that exposure to pesticides is associated with an increased risk of diabetes. Although diabetes is long-suspected as involving an interplay between genetics and environmental factors, emerging research is revealing that contaminants like pesticides may play an important role in the pathogenesis of the disease. These findings add to a growing body of evidence demonstrating that pesticides play a key role in the development of a wide range of all-too-common diseases in the 21st century. To assess the association between pesticide exposure and diabetes, the recent research, Association between diabetes and exposure to pesticides: a systematic review and meta-analysis, examine 21 relevant studies comprising over 66,000 people. Most studies determined pesticide exposure through urinary or blood biomarker analysis, a highly reliable method of testing body burden. Exposure to any pesticide is linked to a 61% increase in diabetes. When looking specifically at type 2 diabetes, researchers found similar results, with any pesticide exposure increasing risk of developing the disease by 64%. However, researchers found that, although on the whole pesticides increased the chance of any diabetes diagnosis, […]

(Beyond Pesticides, June 23, 2015) After years of denial and obstruction, Air Force and Air Force Reserve veterans now have the chance to receive compensation for their exposure to the highly toxic herbicide Agent Orange on contaminated aircraft used after the Vietnam War. Affected veteran’s health issues stem from their time spent on UC-123 transport planes, which during the war were outfitted with spray equipment in the American military’s attempt to eliminate forest cover for Vietcong fighters. After the war, these aircraft were returned to use in the United States for basic transport operations such as cargo shipping and medical evacuation missions. However, these planes never underwent any form of decontamination or testing before being repurposed. Though the Agent Orange Act of 1991 stipulated medical care and disability coverage for sick veterans who  served in the Vietnam War and were exposed to Agent Orange, those who flew in contaminated post-war planes were deemed ineligible. Prior to this recent announcement from the Department of Veteran’s affairs, government officials asserted that the “dried residues” of Agent Orange were not likely to pose a health threat to aircraft crew. However, a study published by the National Academy of Sciences Institute of Medicine in […]

(Beyond Pesticides, June 19, 2015) A new study directly links exposure to dichlorodiphenyltrichloroethane (DDT) in utero to the development of breast cancer later in life. Published in the Journal of Clinical Endocrinology and Metabolism, the study looked at data that were taken from a California program that  evaluated  samples from women during 1960s, when DDT use was popular. DDT is known to be an endocrine disruptor, and is linked to serious health effects. Although DDT has been banned for many years, residues still linger in certain areas of the U.S. and continue to cause environmental and health hazards. The recent study, titled DDT Exposure in Utero and Breast Cancer,  focuses on 118 mothers who were members of Kaiser Foundation Health Plan from 1959-1967 and had daughters that were diagnosed with breast cancer by their 50s. Stored blood samples from these mothers gave researchers an idea of how much DDT they were exposed to during pregnancy or soon after giving birth. They found that elevated levels of DDT in the mother’s blood led to a four-fold increase in the daughter’s risk of developing breast cancer. Among those with cancer, 83% had a form of cancer called estrogen positive breast cancer, which […]

(Beyond Pesticides, June 15, 2015) A community in central Michigan is still dealing with the fallout of a pesticide company that produced DDT nearly half a century ago. St. Louis, MI, a city about one hour north of the state capital Lansing, has long dealt with contamination left behind by the Velsicol Chemical Corporation, which manufactured pesticides in the town until 1963, when it left  and  abandoned loads of DDT in its wake. DDT, known for accumulating in food webs and persisting for decades in soil and river sediment, was banned in the U.S.  in 1972, but problems associated with its prevalent use until that time still plague the community to this day. This situation  has led to a multi-million dollar clean-up effort at taxpayers’ expense  by Environmental Protection Agency (EPA) and the Michigan Department of Environmental Quality (DEQ). EPA took control of the Velsicol plant as a Superfund site in 1982, but decades-long delays in the cleanup of the old chemical factory have left songbirds, and potentially people at risk nearly thirty years later. After years of complaints from residents, researchers  recently reported  that robins and other birds are dropping dead from DDT poisoning. The dead robins and other […]

(Beyond Pesticides, March 13, 2015) Exposure to endocrine (hormone) disrupting chemicals (EDC) results in approximately € 150 billion ($162 billion) in health care costs in the European Union each year, according to panels of scientists tasked by the EU Commission to study their impact. “The shocking thing is that the major component of that cost is related to the loss of brain function in the next generation,” Philippe Grandjean, M.D. of Harvard University, one of the report’s authors, told the Guardian. EDCs, contained in common household products such as detergents, disinfectants, furniture, plastics, and pesticides, interfere with the body’s hormone system either by mimicking naturally produced hormones, blocking hormone receptors in cells, or effecting the transport, synthesis, metabolism or excretion of hormones. These impacts can result in devastating effects on one’s health, including behavioral and learning disorders, such as Attention Deficit Hyperactivity Disorder (ADHD), birth defects, obesity, early puberty, infertility, cardiovascular disease, and childhood and adult cancers. Nearly 100 percent of people have detectable amounts of EDCs in their bodies, according to the introductory guide to EDCs published by the Endocrine Society and IPEN. “Our brains need particular hormones to develop normally —the thyroid hormone and sex hormones like testosterone […]

(Beyond Pesticides, January 30, 2015) Extensive exposure to common chemicals may be linked to an earlier start of menopause, according to a new study out of Washington University School of Medicine in St. Louis. Researchers of the study found that women whose bodies have high levels of these chemicals, including three pesticides, experience menopause two to four years earlier than women with lower levels of the chemicals. The pesticides found to have a significant correlation with an early start in menopause were p,p’-DDE (a metabolite of DDT), β-hexachlorocyclohexane (a byproduct of the production of lindane), and mirex. All three pesticides are organochlorine insecticides or their breakdown products that have been banned for use  in the U.S., but continue to persist in the environment and in the food chain. The study, Persistent Organic Pollutants and Early Menopause in U.S. Women, published this week in the journal PLoS ONE, investigates the link between levels in blood and urine of 111 endocrine-disrupting chemicals (EDCs), or chemicals that interfere with the body’s hormonal activity, and focused on known reproductive toxicants or persistent environmental contaminants. The findings suggest a significant association between 15 chemicals —nine polychlorinated biphenyls (PCBs, which are industrial products), three pesticides, two […]

(Beyond Pesticides, August 7, 2014) Residents of St. Louis, Michigan aren’t used to seeing large excavators and dump trucks haul piles of dirt from their front yards or entire blocks of big, neighborhood trees felled. What they are used to seeing are dead birds ””sometimes even spontaneous, mid-flight deaths of the birds”” and because of a toxic series of events, disasters, and delays spanning decades, the two sights are inextricably connected. As one St. Louis resident described to the Detroit Free Press, dozens of dead robins and blackbirds had been collected from her backyard in the 18 years she has lived there, with the most recent just a couple weeks ago. This experience and other similar stories from the area prompted researchers at Michigan State University (MSU) to start figuratively and literally digging. Matt Zwiernik, Ph.D., an environmental toxicologist at MSU, and volunteers collected 29 dead birds, including 22 robins, last year from a nine-block residential area in St. Louis. The scientific sampling was only a small portion of the dead birds they could have collected, Dr. Zwiernik explained to reporters at the Detroit Free Press, as time, distance, logistics, and access to property sometimes limited collection efforts. Nevertheless, it […]

(Beyond Pesticides, August 5, 2014) A new study finds that female mice exposed in utero to the pesticide DDT are at greater risk for obesity and type-2 diabetes, adding to a growing body of literature linking metabolic diseases to pesticide exposure. The study, titled Perinatal Exposure of Mice to the Pesticide DDT Impairs Energy Expenditure and Metabolism in Adult Female Offspring, was published in the journal PLoS One. Researchers measure and compare metabolic abnormalities in female mice that were exposed in utero to DDT against a control group of those that were unexposed. After exposure, the two groups were then fed high-fat diets for 12 weeks in adulthood. Females exposed to DDT around the time of their birth were more likely to develop insulin sensitivity, glucose intolerance, high cholesterol, and metabolic complications that could result in liver disease. These results suggest that DDT exposure in and around the time of gestation cultivates conditions that increase an individual’s likelihood of accumulating excess fat over the course of one’s lifespan. Additionally, the results find that changes in the way fats and carbohydrates are metabolized can increase the risk of developing metabolic syndrome, which is a precursor to type-2 diabetes. The researchers’ observations […]
