Health News: The Diabetes-Cancer Connection

The relationship between two of today’s most destructive diseases may now be a little clearer. This month, The New York Times reported on the detection of an important link between cancer and diabetes, a correlation so strong it is being compared to the link between smoking and cancer.

The news that Type 2 diabetes patients have an increased risk of developing certain cancers comes from the American Cancer Society and American Diabetes Association and researchers and the National Cancer Institute. One in five cancer patients has diabetes, according to the Times report.

The implication that lowering cancer statistics may hinge on lowering the number of people with diabetes is revealing, but it’s also difficult to hear. That’s because the number of Type 2 diabetes diagnoses today is staggering, and many more cases go undiagnosed. If current trends continue, according to the Centers for Disease Control and Prevention, by 2050, 1 in 3 people in the U.S. will have Type 2 diabetes – a diagnosis that is already linked with a long list of health complications, companion diseases, and death.

A Diet for Prevention

While the Times report reveals an intriguing link between these two devastating diseases, in fact, we have already observed a connection between cancer and diabetes from a nutrition perspective. In an interview with Wild About Health this past summer, Dan Nadeau, Medical Director of the Diabetes and Endocrinology Associates of Maine’s York Hospital, explained that diabetes is not a disease that exists in a vacuum. Having diabetes means you are at increased risk of Alzheimer’s, cancer, heart and vascular disease, inflammation, accelerated aging, and many other complications, he said.

Potent, antioxidant-rich, inflammation-fighting foods that provide protective effects to the body are central to the discussion of prevention, according to experts like Nadeau. Because much of one’s risk of Type 2 diabetes depends on being overweight, he advocates for a change in diet built on daily, ongoing healthy choices in an effort to “quiet the storm” of rampant inflammation inside the bodies of those diagnosed with diabetes and the many at risk.

According to Nutrition Advisor to the Wild Blueberry Association Susan Davis, MS, RD, “The typical western diet, high in refined carbohydrates, fats, sugars and calories actually contributes to inflammation while a diet higher in fruits, vegetables, whole grains and omega 3 fatty acids is anti-inflammatory. Vitamins, minerals, as well as plant compounds have both antioxidant as well as anti-inflammatory properties.” For example, wild blueberries, most known for their high antioxidant capacity, contain flavonoids such as anthocyanins, flavonols, and proanthocyanidins that have been shown to protect us from disease caused by low-grade, chronic inflammation such as cancer and diabetes (not to mention heart disease and arthritis). And when the inflammatory storm is quieted, our risk for disease subsides as well.

Protection on Our Plate

Coincidentally or not, a large portion of today’s research into berries and wild blueberries focuses on both cancer and diabetes prevention potential. We know, for example, that daily consumption of whole blueberries have helped people with a high risk for Type 2 diabetes reduce that risk by increasing the participants’ insulin sensitivity. And, a recent study from the Harvard School of Public Health showed that consumption of anthocyanin-rich fruits can reduce diabetes risk. We’ve also reported on the remarkable study conducted by Lynn Adams, Ph.D. and her team at Beckman Research Institute of City of Hope: they demonstrated the potential of blueberries to inhibit the growth of Triple Negative Breast Center (TNBC), a particularly aggressive and hard to treat form of breast cancer.  We have even covered research that supports that wild plants provide protection from cancer.

Davis has frequently shared with Wild About Health readers her view that we should view food as “treatment” for disease. Just as food can be used defensively as a preventative for disease and the effects of aging, it can be used as medicine to fight disease and counteract the damage done by free radicals that cause inflammation. Such advice is as timely as ever with Type 2 diabetes on the rise and its connection to certain cancers beginning to be established.

Making smart choices in the supermarket and at the breakfast, lunch, and dinner table means better health and lowered risk of challenging diseases like Type 2 diabetes. And when we make efforts toward prevention in important areas like diabetes, we are making efforts toward prevention in others as well.

Why This Story Won’t Be On HBO’s New Series 

 

A scene from a recent episode of Aaron Sorkin’s HBO series The Newsroom takes place in May of 2011. In it, a reporter implores her producer to open the show with news of the debate in Congress about lifting the debt ceiling. It’s the most important story of the day, the week, and the month, she says, and it’s critical the public knows about it. But it’s a crusade with no traction: a provocative tabloid story is consuming the news, and that will lead instead.

The story about the effect of wild berries on a major health epidemic has some similarities to this recent The Newsroom storyline.  Here’s why.

Our Diets are Putting Us at Risk

Unlike some health stories, news about the diabetes epidemic has grabbed headlines. It was recently reported that 1 in 4 children, according to a study from Journal of the American Academy of Pediatrics, either have or are at risk of type 2 diabetes. Type 2 diabetes is being diagnosed in children and teenagers at a once-unthinkable rate, and its growth parallels America’s growing obesity statistics.

“If someone is obese, their risk of developing diabetes is twenty- to fortyfold higher,” Dan Nadeau, Medical Director of the Diabetes and Endocrinology Associates of Maine’s York Hospital told Wild About Health last month. Diabetes is not just a disease that exists in a vacuum: having diabetes means you are at increased risk of Alzheimer’s, cancer, heart and vascular disease, inflammation, accelerated aging many other complications, Nadeau said. A diagnosis of type 2 diabetes can be a death sentence or a wake-up call.

Type 2 is the most common form of diabetes in America today, and while millions of Americans have been diagnosed, many more are unaware they are at high risk. The New York Times recently reported that a dangerous form of type 2 diabetes also develops in people who aren’t overweight. One thing remains clear: diabetes is linked to our diets and it is a lifestyle disease that is, in most cases, entirely preventable.

But the lead is buried in the story. Understanding the impact of completely accessible, wild-grown foods and incorporating them into our diets can transform the lives of those diagnosed and those at risk. The fact is, help for these dire health issues is available—right now, growing in late summer in Maine and parts of Canada—and it’s being made available to us all year round. The effect of berries grown wild under circumstances that make them uniquely powerful against disease and the effect of those berries on the health of millions is front page news – today, this week, and this month.

At least, it should be.

Wild Foods: A Message of Health

We are fortunate to be able to take advantage of real food that is grown naturally in the wild. In areas that are challenged with availability, government, private, and local initiatives continue to make it more available and more affordable. But why differentiate between wild and non-wild foods when it comes to health and disease prevention? We must. While some of us are getting the message about wild-grown foods, others have yet to understand the implications.

First, it is important to know that wild foods occur naturally in their own indigenous environment. They are not planted or cultivated from seeds. Cultivated foods can be healthy, but they are created with human interference, and too often lack the natural nutrients and minerals that today we so desperately need returned to our diets. (Look no further than seedless grapes and iceberg lettuce for examples of human interference that drastically reduces nutrient content.)  With wild, these nutrients are provided, naturally, in their most intense, unadulterated form.

Another important characteristic of wild foods is that they are strong, having adapted to their environment. In fact, the harsher the environment, the more potent the protection they have. Wild blueberries, for example, are grown in rugged terrain in temperature extremes under intense sun exposure, and they have developed natural protection against those extremes. Phytochemicals found in their skins provide antioxidant protection against these stressors. Ready for another headline? When you eat these foods, you get the same antioxidant protection for yourself. And that’s the natural, wild benefit that is right under our nose. Just think what a story like that could become in the hands of Aaron Sorkin.

A Catalyst for Dietary Change

While our diabetes risk can be prevented by our lifestyle choices, some diagnosed cases can even be reversed. Exercise is important, but what you eat has the biggest impact when it comes to weight loss and blood sugar levels. A recent study from the Harvard School of Public Health showed that consumption of anthocyanin-rich fruits can reduce diabetes risk. More than two servings per week has lowered risk compared with those who ate less than on serving per month. Wild blueberries top the list of berries that are high in anthocyanins. These high levels of anthocyanins are concentrated in the deep blue skin of berries like wild blues. They work to decrease the inflammation in the body that accompanies disease and provide us with protection.

Eating potent wild berries is not the only step in a program of prevention, but it is an important one – and it’s one that works. Nadeau cites wild blueberries as the catalyst for making major changes for his patients. This anthocyanin-rich, low GI-food doesn’t spike blood sugar and is packed with fiber. It can also be eaten in robust amounts in things like super-potent smoothies which provide a concrete, good-tasting recommendation that can prompt dietary change.

Researchers have also found that the bioactives in blueberries increase insulin sensitivity, a key factor in prevention. And while this news is exciting, it complements a long list of researchers that have reported on the anti-diabetic effects of blueberry-supplemented diets. Such broad but vigorous research can take time; the bottom line of knowledge can be cumulative. And, while evidence reinforcing the diabetes-wild berry connection continues to grow, there are things we don’t yet understand. The blueberry’s antioxidant effect, their synergy with other foods, and the specific compounds that act on our bodies to prevent disease are things scientists have yet to pinpoint.

Such a story – an accessible way to stop a major health issue – can be easily overshadowed by sexier, quicker, one-stop-shop health breakthroughs. But its impact is huge, and its message worth sending, no matter if it’s in the top block on Atlantis Cable News or buried somewhere on Page 9.

The Bottom Line

The wild blueberry is central in the discussion of how what we eat affects the most important health concerns of our time: cancer, diabetes, Alzheimer’s, and obesity. The research into berries and diabetes prevention is fascinating, but it can be hard to distill it into a single sound bite. The enigmatic details of this powerful connection is one reason it can only be found in nature—fresh, during the season, or frozen, preserving all the nutrition of fresh. As popular as they are, in some ways wild blueberries are still waiting for their close up.
