Bitter Sweet or Toxic?
Indigenous people, diabetes and the burden of pollution

WINNIPEG—Diabetes is now widely regarded as the 21st century epidemic. With some 284 million people currently diagnosed with the disease, it’s certainly no exaggeration—least of all for Indigenous people.
According to the State of the World's Indigenous Peoples Report by the United Nations, more than 50 per cent of Indigenous adults over the age of 35 have Type 2 Diabetes, “and these numbers are predicted to rise.”
Diabetes is referred to as a "lifestyle disease," its rampant spread believed to be caused by obesity due to our increased reliance on the western diet (also known as the "meat-sweet" diet) and our avoidance of regular exercise.
While these may certainly be contributing factors, there is growing evidence that diabetes is closely linked with our environment. More than a dozen studies have been published that show a connection between Persistent Organic Pollutants (POPs) including polychlorinated biphenyls (PCBs); carcinogenic hydrocarbons known as Dioxins; and the "violently deadly" synthetic pesticide, DDT and higher rates of the disease.
“If it is the POPs, not the obesity that causes diabetes, this is really striking if true,” says Dr. David O. Carpenter, director of the Institute for Health and the Environment at the University of Albany.
One out of four Indigenous adults living on reserves in Canada have been diagnosed with Type 2 Diabetes, the most common form of diabetes. The prevalence of the disease appears to be so great that the number of new cases being diagnosed in Canada may exceed the growth of the Indigenous population. It’s no longer uncommon to find children as young as three with the disease. According to government statistics, 27 per cent of all Indigenous people in Canada will have Type 2 Diabetes in the next ten years.
Sandy Lake First Nation, in the Sioux Lookout Zone of northern Ontario, has all but met the mark. A March 2009 study co-authored by Dr. Stewart Harris found that 26 per cent of the community has the disease, the highest recorded rate of diabetes in Canada. With a population of 2,500, the northern Cree community was recently described as an “epicentre” of the epidemic.
There has been little research on the levels of persistent organic pollutants in Sandy Lake; however, according to the First Nations Environmental Health Innovation Network, several neighboring communities who also have high rates of diabetes, like Kitchenuhmaykoosib Inninuwug First Nation, are known to have elevated levels of PCBs in their blood.
The Mohawk community of Akwesasne has its own conflict with diabetes and exposure to POPs. Located across the New York-Ontario-Quebec borders along the St. Lawrence River, three aluminum foundries upriver from the reserve dumped PCBs into the river for decades, contaminating the water, soil, and vegetation.
For many years, Dr. Carpenter has been involved in the study of Adult Mohawks at Akwesasne. Most recently, in 2007, he took part in a study to examine the diabetes/pollution link in the community. “Our study of adult Mohawks showed a striking elevation in rates of diabetes in relation to blood levels of three persistent organic pollutants, DDE, the metabolite of DDT, hexachlorobenzene and PCBs,” Dr. Carpenter explains. “Our results are quite compatible with those of Lee et al.”
In 2006, Dr. Dae-Hee Lee and her colleagues showed that people with the highest rate of exposure to POPs were roughly 38 times more likely to have diabetes than those with the lowest rate of exposure. Further, “they showed that people who were obese but did not have high levels of POPs were not at increased risk of developing diabetes,” continues Dr. Carpenter. “Probably the reason most people get obese is that they eat too many animal fats, and this is where the POPs are.”
The dietary source of POPs was confirmed by the US Environmental Protection Agency in their Draft 1994 Dioxin Reassessment, which has never been formally released to the public. According to the Draft Reassessment, 93 per cent of our exposure to Dioxin comes from the consumption of beef, dairy, milk, chicken, pork, fish, and eggs; in other words, the western diet.
A May 2001 study published in the Journal of Toxicology and Environmental Health drew similar conclusions to the EPA Reassessment. In addition, the study found that “nursing infants have a far higher intake of dioxins relative to body weight than do all older age groups,” and that human breast milk was twice as toxic as dairy milk. It also found that vegans had the overall lowest rate of POPs in their bodies.
According to an October 2009 paper by the Research Centre for Environmental Chemistry and Ecotoxicology at Masaryk University, another major source of POPs, specifically DDT, is the world’s oceans. The paper also found that despite restrictions placed on the use of DDT more than 30 years ago, concentrations of the toxin are on the rise.
Indigenous people carry an unequally high proportion of this global toxic burden. For instance, according to Environment Canada’s National Pollutant Release Inventory (NPRI) there are 212 Indigenous communities in Canada living near or downstream from pulp mills and other facilities that produce dioxins and furans. One striking example is the old Dryden pulp mill near Grassy Narrows which, according to the Grassy Narrows and Islington Bands Mercury Disability Board, dumped tonnes of dioxin-laced mercury wastewater into the English-Wabigoon River system from 1962-70.
Forty years later, the poisonous waste continues to pose a “serious health threat” to Grassy Narrows and the Wabaseemoong First Nations, says the Disability Board. No formal steps have been taken toward remediation by federal or provincial governments.
The Tohono O’odham Nation's experience bears a close resemblance to Grassy Narrows: the world’s highest rate of diabetes can be found in southwest Arizona nation. According to Tribal health officials, nearly 70 per cent of the population of 28,000 has been diagnosed with the illness. The O’odham People make up the second largest Indigenous Nation in the United States.
Lori Riddle is a member of Aquimel O’odham Community and founder of the Gila River Alliance for a Clean Environment (GRACE).
GRACE was instrumental in the 10 year struggle against a hazardous waste recycling plant that operated without full permits on O’odham land for decades. Owned by Romic Environmental Technologies Corporation, the plant continuously spewed effluents into the air until it was finally shut down in 2007.
The Romic plant was not the first contributor to the O’odham’s toxic burden, explained Riddle. Looking back to her childhood, she recalled: “For nearly a year, [when] a plane would go over our heads, you could see the mist. We never thought to cover our water. The chemicals just took over and they became a part of us.”
From the early 1950s until the late 60s, cotton farmers in the Gila River watershed routinely sprayed DDT onto their crops to protect them from bollworms. According to the Agency of Toxic Substances and Disease Registry (ATSDR), each and every year the farmers used roughly twenty-three pounds of DDT per acre.
In 1969, the State of Arizona banned the use of DDT; by this time the river was gravely contaminated. According to the ATSDR, farmers then switched to Toxaphene, a substitute for DDT—until it was banned by the US government in 1990.
Because of these chemicals, Riddle explains, the O’odham were forced to abandon their traditional foods and adopt a western diet. Farms also went into a recession, forcing many families to leave their communities. Companies, such as Romic, began moving on to their territory, exasperating the situation. “It’s taken a toll on our quality of life,” she says. “I’ve cried myself to sleep.”
The O’odham are dealing with what Riddle terms “cluster symptoms,” including miscarriages, arthritis in the spine, breathing problems, unexplainable skin rashes and problems regenerating blood cells. This is in addition to diabetes, which frequently leads to renal failure, blindness, heart disease, and amputations.
More and more studies are showing the link between diabetes and persistent organic pollutants like DDT—stemming from the landmark Ranch Hand study. In 1998, the study found a 166 per cent increase in diabetes (requiring insulin control) in US Air Force personnel who were sprayed with the herbicide and defoliant Agent Orange during the Vietnam War. The study also found that as dioxin levels increased so did the presence and severity of Type 2 Diabetes, and the time to onset declined following a similar trend.
However, Dr. Carpenter notes that because of the widely-endorsed belief that diabetes is a life-style disease related to diet and exercise, the link is gaining little attention by governments, news agencies, or by any of the hundreds of non-profit diabetes foundations around the world. “[It] hasn’t even made it into the medical community at this point,” Dr. Carpenter adds. “It takes a long time to change both medical and public opinion.”
“Clearly one thing everyone can do is to eat less animal fats,” suggests Dr. Carpenter. Several Indigenous communities in northern Manitoba and British Columbia have begun to do this, planting their own gardens and building greenhouses; returning, in a traditional sense, to some of the foods that sustained them for millennia. Others are turning to exercise, which plays a vital role not just in the prevention of diabetes, but in their overall health.
"Also, we must find ways of getting the POPs out of the animals that we eat. That is not going to be easy, given how contaminated we have made the world,” adds Dr. Carpenter. For this, Lori Riddle, who is herself a diabetic, points to the Tribal Council and the Federal Government.

Beyond diet in diabetes
Pollutants interact with obesity to raise diabetes risk
Exposure to dioxins is linked to insulin resistance, which causes diabetes, according to research published this month in Epidemiology.1 Experts say that there is now strong evidence for a link between diabetes and exposure to persistent organic pollutants (POPs), including dioxins, but that this is still being largely overlooked by the medical community.
“There’s just been a flood of evidence linking POPs to diabetics in the last five years,” says David Carpenter, Director of the Institute for Health and the Environment at the University at Albany, New York, USA. “When you put this study in the context of what’s being done in other groups, it gives a very convincing story.”
The researchers, led by Jung-Wei Chang of the National Cheng Kung University in Tainan, Taiwan, measured the levels of serum dioxins, fasting glucose, and insulin in 1234 people living near an abandoned pentachlorophenol manufacturing plant. They used a homeostasis model, which uses fasting glucose and insulin levels to estimate insulin resistance. After controlling for risk factors such as age, obesity, and family history of diabetes, they found a positive association, with a linear dose-response, between serum dioxins and the prevalence of insulin resistance.
Earlier studies have linked a variety of POPs, including dioxins, polychlorinated biphenols (PCBs) and organochlorine pesticides such as DDT, to an increased risk of type II diabetes. Since obesity is linked with greater levels of POPs in the body, scientists speculate that the link between obesity and the development of diabetes might be mediated through these toxins.
“People get obese because they eat too much animal fat, and that’s where the contaminants are,” Carpenter points out. This effect may explain why indigenous populations in Canada are at higher risk of diabetes, Carpenter explains, as they are often exposed to greater levels of POPs than the general population.
One study in particular,2 led by Duk-Hee Lee of the Kyungpook National University in Daegu, Korea, looked at 2016 participants to the 1999–2002 National Health and Nutrition Examination Survey, which took blood samples from a cross section of the general US population, and found no association between obesity and diabetes among people with no detectable levels of POPs in their blood. This implies that the risk of diabetes from obesity could be largely due to POPs, which accumulate in adipose tissue, rather than physiological changes that come with obesity, Carpenter says.
“I am somewhat sceptical of that finding,” says David Jacobs, Professor of Public Health at the University of Minnesota and one of Lee’s co-authors. The association between exposure to POPs and diabetes is stronger in obese people, he points out. But it’s clear that POPs and obesity interact to raise the risk of diabetes, he says.
This would suggest that losing weight may only partially reduce the risk for diabetes. POPs accumulate in adipose tissue — which means that weight loss releases the toxins back into the blood. “That stuff has got to go somewhere,” Jacobs says. “It’s clear that POPs [released from fat deposits] distribute into blood and other tissues.”
Worryingly, some data show a stronger association with diabetes at low concentrations of POPs, Jacobs says. “We have seen that kind of pattern, but it’s very difficult to interpret,” says Jacobs. Because of the difficulty of measuring low-level exposure to these pollutants, a lot more research is needed to confirm whether they have this effect, he argues.
Despite the body of evidence linking POPs and diabetes, the link is still not widely acknowledged in the medical community. “Physicians are totally oblivious to this being a risk factor,” Carpenter says. “The nutrition community have oversold the benefits of fish and underplayed the dangers of contaminants.”
Although production of many of the toxins studied has been banned worldwide, they persist in the environment, are distributed globally, and continue to bioaccumulate in the food chain. Pesticides like DDT, which are still used in malarial regions, can turn up in the food supply all over the world. And others are still on the increase. “[POP] exposure is to some degree going down, except in the case of flame retardants where exposure is increasing exponentially,” Carpenter says. Flame retardants are structurally very similar to PCBs, he points out, and so these too should be investigated for the potential to cause diabetes — especially as children are among the most highly exposed population groups.

Dioxin Exposure and Insulin Resistance in Taiwanese Living Near a Highly Contaminated Area

Abstract
Background: Several epidemiologic studies suggest a slightly increased risk of type 2 diabetes in relation to background levels of dioxins. Little is known about how serum dioxins might affect insulin resistance, a hallmark of type 2 diabetes. We examined the association between exposure to dioxins and insulin resistance.
Methods: We investigated 1234 nondiabetic persons living near a deserted pentachlorophenol factory. Using high-resolution gas chromatography/high-resolution mass spectrometry and blood biochemistry tests, we measured serum dioxins, fasting glucose, and insulin. Finally, we examined associations between serum dioxin levels and the homoeostasis model assessments of insulin resistance and pancreatic β-cell function.
Results: Participants with insulin resistance (index at or above the 75th percentile) had higher dioxin levels (24.3 vs. 19.8 pg WHO98-TEQDF/g lipid) than those without insulin resistance. In both the crude and adjusted models, insulin resistance increased with serum polychlorinated dibenzo-p-dioxins and dibenzofuran (PCDD/F) levels. We found a slight monotonic increase in insulin resistance across the serum PCDD/F categories (P for the trend <0.001). Groups with serum dioxin levels higher than 20.5 pg WHO98-TEQDF/g lipid had higher insulin resistance (adjusted odds ratios of 2.7, 3.5, and 5.0 for 50th to <75th, 75th to <90th, and ≥90th percentile, respectively) compared with the reference group (<9.6 pg WHO98-TEQDF/g lipid [< 10th percentile]).
Conclusions: After adjusting for confounding factors, we found a positive association between serum dioxins and the prevalence of insulin resistance.

Aboriginal women suffer surge in diabetes
Native people, especially women, are developing the disease in their 40s – 30 years sooner than non-natives, study finds
André Picard Public Health Reporter
From Tuesday's Globe and Mail Published on Tuesday, Jan. 19, 2010 9:16AM EST Last updated on Tuesday, Jan. 19, 2010 9:45AM EST
The rate of diabetes among aboriginal women is four times that of women in the general Canadian population, a new study reveals.
Moreover, members of first nations are developing the debilitating illness by their 40s, while in the rest of society it tends to strike people in their 70s.
“Diabetes is a disease of young first-nations adults with a marked predilection for women,” said lead author Roland Dyck of the department of community health and epidemiology at the University of Saskatchewan.
“In contrast, diabetes is a disease of aging non-first-nations adults that is more common in men,” he said.
Dr. Dyck said the big difference in the age of onset has serious implications; diabetes is one of the principal causes of blindness, amputations, kidney failure and heart disease.
The study, published in the Canadian Medical Association Journal, examined trends among patients diagnosed with diabetes in Saskatchewan from 1980 to 2005. The sample included 8,275 aboriginal people and 82,306 non-aboriginals.
The data paint a troubling picture of an unrelenting diabetes epidemic in native communities that “is likely to continue increasing in the foreseeable future,” the paper notes.
Dr. Dyck and his team found that in 2005, 20 per cent of women and 16 per cent of men living in native communities had Type 2 diabetes. That was up sharply from 9.5 per cent and 4.9 per cent respectively in 1980.
Rates of diabetes in the non-aboriginal population rose to 5.5 per cent from 2 per cent in women over the same period, and to 6.2 per cent from 2 per cent in men.
Over all, the incidence (the frequency of development of diabetes in a population over a given time period) and the prevalence (the number of people currently suffering from the disease) were both about four times higher among aboriginal women and 2.5 times higher among aboriginal men.
The epidemiological study was not designed to explain the underlying causes of this disparity, but Dr. Dyck put forth a couple of likely explanations.
First, it has been well documented that rates of overweight and obesity are significantly higher in native communities. (Excess weight, particularly in the abdominal area, is a key factor in Type 2 diabetes.) In aboriginal communities, women are more likely to be overweight or obese than men, and at a younger age.
Second, there are high rates of gestational diabetes in pregnant aboriginal women. Those who develop diabetes during pregnancy are at high risk of developing Type 2 diabetes later in life, and so are their children.
“Gestational diabetes has been implicated in the intergenerational ‘vicious cycle’ by increasing diabetes among the offspring,” Dr. Dyck said.
He added that the differences in the epidemiology of the disease in native and non-native people means prevention programs should be different as well.
In particular, programs for first nations should focus on women in their reproductive years and on preventing gestational diabetes, Dr. Dyck said.
There are three distinct forms of diabetes: Gestational diabetes is a temporary condition that occurs during pregnancy; Type 1 diabetes, usually diagnosed in children, occurs when the pancreas is unable to produce insulin; Type 2 diabetes occurs when the pancreas does not produce enough insulin, or the body does not effectively use the insulin it produces.
About 90 per cent of diabetics have Type 2 disease, which is usually a consequence of obesity, inactivity, poor diet and aging. Poverty is also strongly associated with diabetes, which could be another factor that helps explain high rates in native communities.
Pollution and Insulin Resistance
Dear Friends,

Male rats fed fish oil from farmed salmon developed insulin resistance, obesity and related health issues.
A new study in rats shows that persistent organic pollutants (POPs) – at levels found in food – cause insulin resistance and associated obesity and liver disease in the animals. The study is the first to show this experimentally. Insulin resistance can lead to type 2 diabetes, which is becoming a global epidemic. The association between high levels of POPs in people and increased chance of developing diabetes has been known since 2006. Until now, scientists could not positively conclude that POPs influenced the onset of diabetes.
Context
Persistent organic pollutants (POPs) are a diverse group of toxic chemicals that resist degradation and can remain in the environment for decades. The compounds are known to adversely affect health in people and wildlife.
POPs include organochlorine pesticides, polychlorinated biphenyls (PCBs), dioxins and furans. Many of the synthetic chemicals were created for use in agriculture and construction. Others were used in, or are byproducts of, industry. Some – such as dioxins – also occur naturally as a result of burning and combustion.
The US and Europe banned the production and use of certain POPs more than 30 years ago. This ban was expanded globally during this century. Yet, due to their chemical nature, they can remain intact, persist in the environment and accumulate in wildlife and people. They build up in farmland soils and waterways, contaminating wildlife and making their way up the food chain. People are exposed through eating contaminated fish, poultry, meat and dairy products.
The hormone insulin helps in the uptake and storage of the sugar glucose – a basic regulator of metabolism. Insulin resistence occurs when cells do not respond to the hormone. This allows glucose levels to build up in the blood and leads to more serious health problems. Additionally, insulin and the uptake of glucose regulate the formation of fat.
In the U.S., one out of four adults have metabolic abnormalities that are associated with insulin resistance. Typical symptoms of insulin resistance are fatigue, obesity, accumulation of fat around the belly and difficulty regulating the blood levels of fat and sugar. Insulin resistance is the underlying cause of type 2 diabetes, cardiovascular problems and liver disease.
These drastic increases in metabolic disorders cannot be totally explained by current known risk factors – high fat diets and lack of exercise. Based on animal and human research findings, some scientists suspect that POPs have the potential to contribute to the diabetes epidemic that threatens people around the globe. Human studies have found associations between an increased chance of developing type 2 diabetes and higher levels of POPs in the body (Lee et al. 2006). Animal research has pointed in the same direction.
What did they do?
Adult male rats were fed for 28 days either crude or refined fish oil obtained from farmed Atlantic salmon carcasses.
The crude fish oil contained the levels of POPs that people are typically exposed to after eating the fish. The refined fish oil contained no POPs and was fed to the control rats. The levels of fat in both diets were the same.
After exposure, the researchers measured body weight, whole-body insulin sensitivity and levels of POPs in each group. They compared the levels of fat, triacylglycerol, diacylglycerol and cholesterol in the rat livers.
They also determined how well rats could regulate sugars and fats and measured the expression of several key genes that are thought to be involved in the metabolic process.
In a parallel study, fat cells were exposed to the types of POPs that were stored in the fish fat cells at similar levels found in the salmon oil. The effects on sugar uptake by the cells were measured.
What did they find?
Adult rats exposed to the crude fish oil – which contained the POPs mixture – put on belly fat and developed insulin resistance and liver disease. The rats could not regulate fat properly. They had higher levels of cholesterol and the fatty acids triacylglycerol and diacylglycerol in their livers.
In contrast, none of these changes were seen in the rats that ate fish oil without the POPs.
Although blood levels of insulin and sugar were similar among rats with either diet, the rats exposed to POPs had impaired insulin action. The POPs also altered the expression of number of genes involved in metabolism, which could explain the changes in fat and sugar regulation.
Similar results on insulin and gene expression were seen in the cultured fat cells that were exposed to a POPs mixture similar to that found in the fish oil. The POPs – especially the organochlorine pesticides – drastically inhibited insulin's action and the cells' ability to take up glucose, a first step in insulin resistence.The cells expressed fewer of the genes that regulate fat and sugar levels.
Further analysis showed the liver and fat tissue differed in the components they predominantly store. PCBs and organochlorine pesticides were measured in both liver and fat tissue while certain types of dioxins and furans were more abundant in the liver.
What does it mean?
Based on this study, daily exposure to POPs mixtures in food at levels found naturally in the environment leads to insulin resistance and an impaired ability to metabolize fat and sugar in adult male rats. The levels measured in the rats' fat tissues were relevant to humans, as they were similar to those previously reported for middle-aged Europeans.
This rodent study is the first to find that POPs can cause abnormal insulin action and adds an important missing piece to the growing body of human research that has found associations between POPs levels and insulin resistance that could cause such serious health problems as type 2 diabetes, obesity and liver disease.
Generally, animal studies provide a way to ask and answer health-related questions that cannot be studied directly in people. Humans and rats share similar hormones that work in the same general way to guide metabolism and reproduction. Because of these similarities, rats and mice are used to assess both potential drug therapies and potential effects from environmental toxicants. Results from animal studies supply insights into what might be occurring with respect to health and disease in people.
Animals and people accumulate these long-lived compounds from food and store them in fat. Most of us carry at least some types of the chemicals in our bodies. The authors say their results indicate that POPs – as with some other indicted environmental chemicals found in air pollution and plastics – "provide additional evidence that global environmental pollution contributes to the epidemic of insulin resistance-associated metabolic diseases."
The World Health Organization estimates that more than 300 million people will die from disease associated with insulin resistance and metabolic disorders by 2015. The current strategies for prevention include limiting dietary intake and increasing physical activity. This study suggests that considering the role of POPs may be warranted in prevention strategies.
Current methods of risk assessment may also fall short in protecting health, since different types of POPs mixtures impaired insulin action differently. Some did, while others did not. The dioxin and dioxin-like PCB levels that changed insulin action did not fall within the standard measure of toxicity – called the total toxic equivalent (TEQ) concentration – that is currently used to regulate safe exposures to environmental chemicals. The findings "demonstrate that risk assessment based on TEQ assigned to dioxins and dioxins-like PCBs" does not include the risk of insulin resistance, according to the study's authors.
POPs production and use are regulated worldwide. For example, in the U.S., regulations imposed by the Environmental Protection Agency have significantly reduced the release of dioxins and furans. Globally, a number of international laws limit or ban their use.
The chemicals classified as POPs do not degrade easily, so even limited production will still have an additive effect over the years. Because of this, POPs will continue to impact the environment – and possibly human health – into the future.
