Do Statins Cause Diabetes and Heart Disease?

Posted: 09/12/10 10:00 AM ET

I recall reading a scientific paper in the Journal of the American Medical Association a number of years ago by Dr. David Jenkins from the University of Toronto. He showed that using a combination of soy, fiber, almonds, and plant sterols (cholesterol-lowering fats) could lower cholesterol levels as much as statin medications.(i) Diet can lower cholesterol as much as statins--a surprise to many but common in my practice. Using a comprehensive approach of diet and lifestyle change, I routinely see effects that are more powerful than any medication. That was not why the article struck me. It was a finding buried in the text of the paper.

What I found fascinating was that the patients who lowered their cholesterol with statins had higher levels of insulin, while those who lowered their cholesterol through diet had lower insulin levels. Why is that important? Because elevated insulin levels are the first step on the road to diabetes--they make you gain weight around the middle, cause high blood pressure, increase inflammation, and promote stickiness of the blood. Each of these conditions, in turn, contributes to heart attacks and heart disease.

On reading this, the question that lingered in my mind was: Did statins contribute to the development of pre-diabetes and diabetes which are among the most significant risk factors for heart disease? In other words, did lowering cholesterol with statins--a treatment purported to reduce the risk of heart disease--actually increase the risk of heart disease by some other mechanism?

In treating thousands of patients with pre-diabetes, diabetes, high cholesterol, and heart disease, I have noticed one thing: Lowering insulin through diet and lifestyle corrects almost all of the risk factors for heart disease. It lowers blood pressure, increases good cholesterol (HDL), lowers triglycerides and bad cholesterol (LDL), leads to weight loss, lower levels of inflammation (C-reactive protein), and thins the blood. Lowering insulin even increases the light fluffy harmless cholesterol and lowers the level of small dense harmful cholesterol particles.

Lowering insulin is a good thing. However, statins--the best selling class of drugs on the market--appear not to do this. Do they actually increase the risk for diabetes and thus heart disease by increasing insulin levels?

The Truth about Statins and Insulin

The answer, according to a recent study in the Lancet, is yes statins do increase the risk of diabetes.(ii) The authors completed a meta-analysis of both published and unpublished randomized controlled trials from 1994 to 2009 for a total patient group of 91,140 who were treated with statins or a placebo. In the patients treated with statins there was a 9 percent increase in the risk of diabetes. The authors suggest this is a minimal risk and that current guidelines for cholesterol treatment should not change. I would suggest we think a little more deeply.

The study did not analyze any data for pre-diabetes, which dramatically increases the risk of heart disease well before a formal diagnosis of diabetes can be made. It could be that by taking these medications many people developed pre-diabetes or their pre-diabetic condition worsened. If this is true, the full risk of statins was not appreciated. The researchers also failed to consider a simple question: Why should we use a medication with significant potential risks when other treatments have proven MORE effective for reducing the risk of heart disease?

The treatment I'm talking about is dietary and lifestyle change--popularly referred to as lifestyle medicine. The recent "EPIC" study published in the Archives of Internal Medicine studied 23,000 people's adherence to 4 simple behaviors--not smoking, exercising 3.5 hours a week, eating a healthy diet (fruits, vegetables, beans, whole grains, nuts, seeds, and low meat consumption), and keeping a healthy weight (BMI less than 30). In those that adhered, 93 percent of diabetes, 81 percent of heart attacks, 50 percent of strokes, and 36 percent of all cancers were prevented. (iii)

The fundamental focus of lifestyle or functional approaches (which includes nutrition, exercise, and stress management) is the restoration of normal function and balance in each individual. When you do this, risk factors and symptoms go away automatically. Conventional interventions, on the other hand, are primarily focus on blocking, interfering with, or excising a biochemical or physical manifestation of disease. This is the reason biology shifts towards normal when using lifestyle medicine, instead of medication, and the only side effects are good ones: weight loss, more energy, better sleep, increased well being, a reduction of most disease, and increased longevity.

While it is still a matter of public debate, there is ample evidence that lifestyle therapies equal or exceed the benefits of conventional therapies such as medication and surgery. Nutrition, exercise, and stress management can no longer be considered alternative medicine. They are essential medicine, and often the most effective and cost-effective therapies to deal with the chronic disease epidemic that afflicts millions of Americans and is now the primary cause of death worldwide.

Addressing the Global Burden of Chronic Disease

Chronic disease has replaced infectious and acute illnesses as the leading cause of death in the world, both in developed and developing countries.(iv) In 2002, the leading chronic diseases, including heart disease (17 million), cancer (7 million), chronic lung diseases (4 million), and diabetes (1 million), caused 29 million deaths worldwide. These ailments are almost entirely attributable to lifestyle risk factors including poor diet, sedentary lifestyle, and tobacco and alcohol use. The misperception that these diseases affect primarily developed and affluent societies has led to a misappropriation of resources, which fails to deal with the exponential growth of chronic lifestyle- and diet-related disease.

By 2030, fifty million will die from preventable chronic diseases compared to less than 20 million from infectious diseases. We need to include chronic disease in our global efforts to improve health. In Haiti, the poorest nation in the Western hemisphere, the major admitting diagnoses to the largest and main public health hospital where I worked after the earthquake in January 2010 was not tuberculosis or AIDS, but heart disease, diabetes, and hypertension related heart failure.

The major global health policy makers and agencies do not allocate appropriate resources to the prevention of chronic lifestyle diseases either because they have yet to recognize the problem or the economic and social benefits of focusing on chronic disease are underestimated. Heads of state, health ministries, the World Health Organization, academic and research institutions, non-governmental organizations, private donors, the World Bank, and the United Nations allocate only a fraction of their resources to chronic disease prevention despite a rich evidence base for the role of lifestyle and diet in the prevention of the major chronic diseases.

When compared to doing nothing, the argument can be made for high cost, technological interventions. When compared to changing our medical care system from one focused on treating end-stage disease, to one whose goal is to prevent disease and promote optimal health through nutrition, lifestyle, stress management, and adjunctive complementary therapies, the conversation shifts dramatically.

Diet, Lifestyle, and Chronic Disease: A Model for Increased Quality of Care and Lower Costs

Let's briefly look at the science of nutrition and compare it to efforts for preventing or treating chronic disease with medication. This will highlight the powerful, cost-effective, and critical role nutrition plays in the cause, prevention, and treatment of chronic illness.

Science provides a firm foundation for moving nutritional and lifestyle interventions to the center of medical practice and public policy.(v) A single nutrient, food, or lifestyle habit when studied as an isolated intervention, while helpful, may not show significant effect, but when assessed collectively, the power of lifestyle over pharmacological approaches to prevent and treat chronic disease is overwhelming. That is why we have to stop looking at single nutrients or interventions and look at the whole picture. In his recent article in the Journal of the American Medical Association, Dr. David Ludwig of Harvard calls for a shift from a nutrient-based to a whole foods based approach to our dietary guidelines.(vi) He indicts our current dietary guidelines showing how these recommendations have led to our chronic disease epidemic. Let us eat food, he says--real, whole, fresh, complex, interesting food. It's the whole picture, not just fats or carbs or this or that nutrient that makes a difference.

For example, healthful lifestyle practices in an elderly population that included eating a whole foods Mediterranean-style diet, exercising moderately, not smoking, and moderate alcohol consumption were associated with nearly a 70 percent reduction in death from all causes.(vii) What's remarkable is that these people didn't start this healthy lifestyle until they were 70 years old, yet they still reduced their risk of death by 70 percent compared to a similar group of elderly who didn't follow a healthy lifestyle.

Other studies(viii), (ix), (x) showed similar results including an 83 percent reduction in heart disease,(xi) 91 percent reduction in diabetes in women,(xii) and a 71 percent reduction in colon cancer in men.(xiii)

The Lyon Diet Heart Study,(xiv) showed a 79 percent reduction in heart disease in patients with established heart disease after a few years of following a Mediterranean diet. In another study of patients with existing heart disease, an integrated lifestyle approach of a plant-based diet, exercise, smoking cessation, and stress reduction found a 50 percent reduction in heart attacks and heart disease related deaths.(xv)

The evidence is simply overwhelming that healthful dietary patterns which include whole grains, legumes, nuts, vegetables, fruits, olive oil, fish, and, perhaps, moderate alcohol intake are associated with a decrease in chronic disease and death from all causes. The harmful effects of trans and certain saturated fats, refined carbohydrates, and other food additives or toxins are well known in the medical literature.

It is time to start putting into practice what we know, and stop the domination of our medical practice by the pharmaceutical industry. The Lancet paper on how statins increase the risk of diabetes should be front-page news. Medications such as statins that cost more, are less effective, and lead to serious side effects including diabetes should not be our first line of treatment for preventing or treating heart disease. The recent proposal that statins be handed out with cheeseburgers and fries at fast food restaurants is dangerous and misses the point.

You can't eat a horrible diet, avoid exercise and expect to be healthy. A whole foods, plant-based diet, moderate physical activity, not smoking, and creating a supportive social network of friends and family is the best medicine. It works in ways we don't yet understand and don't need to--just eat real food, enjoy, and don't worry. Your body knows what to do from there.

To your good health,

Mark Hyman, MD

$ 24 000 000 in funding for research from NIH about improving heart health via Transcendental meditation(TM)
done at mum.edu institute of natural medicine and prevention by Robert Schneider MD FACC et al at partner universities

has resulted in TM being accepted for category one CME credit

from hearing him speak i conclude that there is nothing beter than TM for heart health

Dr Schneider indicated in one study TM was shown as effective as statins

according to DR Whitaker even garlic is as effective as statins [ though i dont recommend it maybe at the level of consumption by itslef]

but TM cna be consumed as presribed every day

and it TM program solves the common critique as you know :

who will and can comply with all these lifestyle of habits recommendation

lifestyle seems easy enough to change but when one considers it as habit

in any case DR Schneider , nancy Lonsdorf MD DR stuart Rothenberg Dr keith wallace DR Steele Belok at harvard etc are very valuable allies in bringing frankly sanity to the mainstream medical profession

Fabulous article, Dr. Human.

Unfortunately many patients despite their best efforts are unable to make the type of lifestyle changes required to have a significant loss of weight or drop in cholesterol. As well people with a genetic tendancy to heart disease and high cholesterol levels may do everything right and still not be able to get their cholesterol levels down to a low risk level.

In terms of the increased risk of diabetes. That paper shows that for every 255 patients treated with statins 1 patient is at increased risk for diabetes. When you compare that to the 1 heart attack prevented in every 35 patients treated the evidence is still in favour of statins. Which is what the authors of the paper concluded. This does not mean that further research into the link between diabetes and statins isn't warranted.

We should aim to get rid of statins.

For those who need statins, Coenzyme Q and adequate levels of vitamin D, especially, may help reduce the side effects.

Is there a way for lay persons to access this paper by Dr. David Jenkins from the University of Toronto so we can see the actual trial data and the actual diet involved?

Great article articulating the push-pull between medical and healthy living proponents. Our society is used to the "quick fix" by popping a pill to reduce cholesterol and treat other ailments. Transitioning to a whole foods diet (e.g., whole grains, fruits, vegetables, legumes, nuts and seeds) can take time, but the long term benefits are well worth it. My hope is that as people become more aware of the impact diet has on their health, that they will not only make changes in their daily diets, but demand the same from school cafeterias, work places, restaurants and hospitals.

" What I found fascinating was that the patients who lowered their cholesterol with statins had higher levels of insulin, while those who lowered their cholesterol through diet had lower insulin levels. "

Really? (sarcasm big time).

Come on.  People who have diets that cause high cholesterol in the first place are usually eating too many carbohydrates (sugars) and this is what causes insulin levels to rise.  Therefor, anyone with high cholesterol who depend solely on statins to get their cholesterol levels down should have higher levels of insulin due to their bad diets in the first place.  This is basic common sense/logic 101. 
09:57 PM on 09/13/2010
This is exactly what I thought too.
11:50 AM on 09/14/2010
I believe you and Dr. Hyman are on the same page. Take a drug, keep the same diet and something else in the body will have to give (increased insulin). If it is such common sense/logic then why are so many people prescribed these drugs and diet does not change. Hmmmm.

"Lowering insulin even increases the light fluffy harmless cholesterol and lowers the level of small dense harmful cholesterol particles."

I thought that High-Density Lipoprotein cholesterol (HDL-C) was supposed to be the "good" cholesterol and the "light, fluffy" Low-Density Lipoprotein cholesterol (LDL-C) was supposed to be the harmful cholesterol.

True.  You need a good ratio of good to bad cholesterol in order to clean out the bad cholesterol.  It is the good cholesterol that "wraps" the bad stuff and get's it out of the blood and passed out of the body.  Eating high doses of omega-3 fats like that in fish (fish oil pills are a good supplement) help raise the good stuff which helps lower the bad stuff.

The big fluffy particles don't cause the damage. The damage is caused by VLDL, Very Low-Density Lipoproteins, which are not big and fluffy.

I have gotten excellent results (cholesterol, blood glucose, weight) from sensible eating (emphasis on whole grains, fresh fruits and vegetables, high fiber, low fat, etc.; lean meats in moderation), regular exercise (aerobic and resistance), good sleep habits, and managing stress. No interest in Big Pharma's cash cow meds for what I can manage by making good choices.

What if high cholesterol is "GENETIC"? My dad had high cholesterol and so do I. I've eaten healthy for over 40 years and have also gotten a lot of exercise through the years. In oder to lower my LDL I went on a very strict diet for 8 weeks just to see if my diet would make a difference although I've always eaten healthy..my LDL was lowered only 7 points and during the 8 weeks I lost 6 pounds which I didn't need. My LDL was 154 at the end of 8 weeks, by the new guidelines it is supposed to be around 100. Diet does not work for me. I take 10 mg. statin three times per week and that has lowered my LDL to 101. I don't like taking a statin but don't have a choice.

Exactly.  btw, death by heart attack has been reduced by 20% in the USA since statins were introduced 20 years ago.
11:48 AM on 09/13/2010
Depends on what you mean by "high". You'll notice that the standard drops every year, thus putting more people in the bulls-eye of statin use. It seems odd that in this obviously multifacted disease, the medical industry only pinpoints one cause -- cholesterol. What you also need to know about is inflammation. An hs-CRP test will do that. Why does fish oil and aspirin (and reducing stress) work? Because it lowers inflammation. There are plenty of folks with "high" cholesterol who never get CAD and many CAD patients with excellent cholesterol balance. The other negative impacts of statins, including cognitive, issues cannot be reversed. Read a few studies and you'll see amazing things. For example: (Published by B. Tamara, American Heart Journal, Sept 2008): One curious finding was that, "Each 10 mg increase in total cholesterol level was associated with an astonishing 4% decreased risk of in-hospital mortality from heart failure." All I'm saying is that we need to look more deeply than just the lipid theory to take care of our hearts. Let's not get sucked into the conventional wisdom. It's been wrong too often. They tried to put my 89 year old mother on statins! She made it that far with a 270 total cholesterol, she's probably not going to get much more out of an expensive statin. Silly doctors!

Many comments posted here bash pharmacy companies for pushing pills. If you have not noticed, people are living MUCH longer now because of medications and how we can medically manage so many chronic illnesses. Not all illnesses can be treated with diet and exercise. I work with dialysis patients every day. They would not be living without the life saving treatments and medications they take and endure. And, believe me, these patients are NOT on dialysis due to pharmacy companies. Most are on dialysis due to non-compliance with their medical treatment.

Most of the increase in life expectancy -- remember, it's an AVERAGE -- was due to the advent of antibiotics (which saved people who otherwise probably would have died young of infectious diseases), the reduction in infant mortality and the development of vaccines against once-deadline childhood diseases such as diphtheria, whooping cough and polio. The average person who reached age 60 in 1940 could expect to live only about four years longer than the average person who reaches 60 today.

Chronic illness was not a major factor in death until the last fifty years. Coincidence? I don't know. Where was diabetes when we as a society were eating whole foods, working hard and filling our lives with family, friends and love? I guess you should be glad we have the myriad of medications to offset our unhealthy diets and lives.
10:17 PM on 09/12/2010
As a NP seeing patients every day, I always try to get patients to do the lifestyle change as written about above. Some try it, but most would rather take a pill. I wonder if those who exercised and took a statin would have higher levels of insulin. Probably not. It's those who are overweight, with metabolic syndrome that have the increased insulin level.
There are natural ways to lower cholesterol. The first statin, Mevacor, was made with red yeast rice. Diet and exercise require self control. Taking a pill does not.
10:51 PM on 09/12/2010
Statins are made from red yeast rice from what my pharmacist told me, in order to get enough from a supplement you'd have to take a LOT, which would be almost impossible in order to get the LDL down.I"m wondering if statins are currently being made with red yeast rice or if that has changed?

I'm not a statistician or scientist, but I don't understand how such a statement can be logically valid. Without knowing whether diabetes, a heart attack, a stroke etc. would have occurred in a particular individual, how can you say it "was prevented"?

You can say that those following the regimen had 81% fewer heart attacks, 93% fewer cases of diabetes, etc., but that's not the same thing.
