How to eliminate 50 percent of all coronary events

The European Society of Cardiology estimates a 50 percent reduction of coronary events if you can stabilize soft, vulnerable plaques (1). We are often led to believe that plaques you can see on an angiogram are “killer” plaques. It’s true that if they are large enough to obstruct blood flow, they will decrease oxygen transfer to the heart muscle cells making them more tired with less effort.

This is the definition of stable angina. It simply means it takes less effort to over-exert the heart muscles before they fatigue. However, you need approximately a 90 percent total obstruction of the blood vessel to develop stable angina. These plaques account for most of the plaques you might find in an angiogram. This is why if you take an angiogram, you are often immediately wheeled into the operating room to have a stent put into the artery with the belief you are only seconds away from an immediate heart attack and death.

However, the same angiogram can’t see a few plaques (because they are so small), known as the soft, vulnerable ones. When soft, vulnerable plaques rupture (like a pimple), then you have the death and disability (i.e., damaged heart tissue) that truly characterize heart disease. Technically, this is called an acute coronary event, and it has very little to do with the stable plaques that can cause angina. It is this small number of “rogue” soft, vulnerable plaques that are the true killers in heart disease (2,3).

The ultimate cause of plaque rupture is cellular inflammation inside the plaque. Cellular inflammation degrades the fibrous external coating of the plaque. Usually inside these soft, vulnerable plaques are also a lot of macrophages engorged with lipids. This is called the “necrotic core”. When the plaque bursts, these lipid pools are released into the bloodstream causing platelet aggregation and the rapid blockage of the artery resulting in a complete restriction of blood flow (as opposed to a limited restriction of blood flow with a typical stable plaque that will never rupture). It is estimated that about 75 percent of all coronary events are caused by ruptures of the soft, vulnerable plaques (2).

As I mentioned above, the really scary part of this story is that there is no type of imaging technology that can detect dangerous soft, vulnerable plaques. In essence, you don’t know if you have them or not. This is why the prediction of impeding cardiovascular events remains a guessing game. Even more interesting is that these soft, vulnerable plaques seem to form rather quickly (in about 10 years) as opposed to growing slowly over a lifetime (4). Moreover, the rate of growth of these soft, vulnerable plaques is strongly correlated with increasing insulin levels in the blood (4).

So what does this mean for people who don’t want to die from a sudden rupture of soft, vulnerable plaques that can’t be detected? The first thing is to reduce the inflammation within the plaque. Surprisingly, there is only one clinical study that has ever been published that addressed this question, and it used fish oil (5). This study indicated that if you give patients relatively high doses of fish oil, you could see a definite remodeling of the soft, vulnerable plaques in about 40 days compared to subjects taking a placebo composed of safflower oil. The plaques in the subjects taking the fish oil became less inflamed, had higher levels of omega-3 fatty acids, fewer macrophages and more well-formed fibrous caps compared to those taking the placebo. So taking a therapeutic level of fish oil for a lifetime seems to be a good way to reduce the rupture of these plaques.

Another way to potentially reduce their formation in the first place is lower insulin levels. The reason insulin levels are elevated is because organs, such as the adipose tissue, the liver and the muscles, are also inflamed (6). The best way to reduce that systemic inflammation is to follow the anti-inflammatory diet and take therapeutic levels of fish oil for a lifetime. Your success is best measured by the AA/EPA ratio in the blood. Call me crazy, but I think that’s what I have been recommending for the past 16 years (7).

If you’re fat, you may be OK

It is well known from epidemiological studies that about 30 percent of obese individuals and 50 percent of overweight individuals are relatively healthy in terms of cardiometabolic risk factors (1). The same study also indicated that about 25 percent of normal-weight individuals have significant cardiometabolic risk. A follow-up study indicated individuals defined as “metabolically healthy obese” are not at any long-term risk of heart disease (2).

Is the world turning upside down?

I explained the reasons behind these paradoxical observations in my most recent book, “Toxic Fat,” published three years ago (3). It simply depends on what type of fat cells you have. If you have healthy fat cells (“good” fat), they will pull excess arachidionic acid out of the bloodstream and store it in the fat cells. This buried arachidonic acid can spread inflammation to other organs that ultimately results in the appearance of cardiometabolic risk factors. On the other hand, if you have “bad” fat (unhealthy or sick fat cells), they are not very effective in removing arachidonic acid from the bloodstream. Once this happens, circulating arachidonic acid can metastasize like a cancer to other organs. This begins a very slippery slope toward the early development of cardiometabolic diseases, such as diabetes and heart disease. Finally, you get to the stage of dying fat cells that are surrounded by inflammatory macrophages. Now you are in true trouble as the previously stored arachidonic acid is more rapidly released back into the bloodstream.

Now let's fast forward to a new article in the Journal of the American College of Cardiology (4) that simply confirms what I wrote about fat cell inflammation three years ago. As with the earlier epidemiological study, researchers found that about 30 percent of the obese subjects had little inflammation in their fat cells as indicated by the absence of inflammatory macrophages. This percentage of obese patients was essentially identical to that found in the earlier epidemiological study (1). When the arterial blood flow of the metabolically healthy obese was compared to lean subjects, the rates were virtually identical, whereas the arterial blood flow rates were much lower (that's bad) in the obese subjects who had significant fat cell inflammation.

Unfortunately, their characterization of inflamed fat cells was incorrect. What they were really looking at was dying fat cells. The fat cells of these so-called metabolically healthy obese subjects were already sick (i.e., bad fat) since there were metabolic markers (hyperinsulinemia, increased TG/HDL ratios, elevated blood glucose and increased CRP levels) that indicated that inflammation was already spreading to other organs (such as the liver, muscles and pancreas).

The best way to know if you have truly healthy fat cells (no matter how many you have) is to have a low AA/EPA ratio in the blood. This remains the best clinical marker of the true health of the adipose tissue. If you have healthy fat cells (good fat), then you can expect cellular inflammation in other organs will be reduced leading to a longer and better life no matter what your weight.

Pass the salt please?

One of the great “truths” in cardiovascular medicine is that to prevent stroke and cardiovascular death you reduce your salt intake. But is it true? A new analysis of the existing literature from the Cochrane Library indicates this may not be the case (1). Analyzing a great number of published studies, researchers came to the conclusion that there is no strong evidence to support the idea that salt restriction reduces cardiovascular disease or all-cause mortality in people with either normal or increased blood pressure. Furthermore, they found that while reducing salt intake did decrease blood pressure, it also increased the risk of all-cause death in people with existing congestive heart failure.

If that wasn’t enough, an article in the May 4 issue of the Journal of the American Heart Association found that low salt increased the risk of death from heart attacks and stokes, while not reducing blood pressure (2). This study was done with middle-aged Europeans and followed them for nearly eight years. During this time, the less salt they consumed, the greater the number who died of heart disease.

Needless to say, the American Heart Association (the same people who recommend eating lots of omega-6 fats) was enraged, similar to the Wizard of Oz telling Dorothy to ignore the man behind the curtain.

So why might restriction of salt consumption cause increased heart attacks? The reason may be due to increased insulin resistance induced by salt restriction (3). Insulin resistance increases insulin levels, and if that is combined with increased consumption of omega-6 fatty acids (remember the American Heart Association), you now have a sure-fire prescription to produce more arachidonic acid. It’s the inflammatory eicosanoids derived from arachidionic acid that would cause inflammation in the arterial wall leading to a heart attack.

This is not to say that some people are not salt-sensitive (African-Americans are particularly so), but I believe the problem is more a matter of balance. You need some sodium, but you also need potassium to balance it. This is confirmed by a recent study from Harvard Medical School that demonstrates that the higher the sodium-to-potassium ratio in the blood, the greater the likelihood of cardiovascular mortality (4). The relationship for increased death was significantly greater for a high sodium-to-potassium level than simply the sodium level itself.

Getting sodium in your diet is easy (sprinkle salt on your food), but getting adequate levels of potassium means eating a lot of fruits and vegetables. So rather than restricting salt intake or taking drugs (i.e. diuretics) to reduce the levels of sodium in the body, think about eating more fruits and vegetables if your goal is to reduce the likelihood of a heart attack. Oh, yes, also ignore the advice of American Heart Association and take more omega-3 and less omega-6 fatty acids.

Obesity continues to climb

Last week the Robert Wood Johnson Foundation reported that more than 12 states now have adult obesity rates greater than 30 percent, and that one in three children are either overweight or obese. However, 16 years ago, no state in the United States had an adult obesity rate greater than 20 percent. So in less than a generation, adult obesity has skyrocketed. Yet at the same time, according to the Centers for Disease Control, the percentage of overweight people has remained fairly constant since 1960, while the percentage of obese individuals has increased significantly since 1980. What this suggests is that there is a genetic component that can be activated in those individuals predisposed to gain weight. Once activated, accumulation of excess fat accelerates.

I feel the driving force between this activation of genetic factors is the increasing inflammatory nature of the American diet. We know that it is elevated insulin levels that make us fat and keep us fat. But what really causes insulin to become elevated in the first place? The simple explanation is that it comes from eating excess carbohydrates. However, that is too simplistic an explanation since one-third of adult Americans who are thin are also eating excess carbohydrates.

A more comprehensive answer is it’s insulin resistance that causes elevated insulin levels. Insulin resistance is a consequence of disturbances in the body’s insulin-signaling pathways in the cell caused by cellular inflammation. My most recent book, “Toxic Fat,” goes into great detail on this subject (1). But simply stated, the more cellular inflammation you have in your cells, the greater the likelihood of insulin resistance. And if you are genetically prone to gain weight, increasing insulin resistance will really pack on the extra fat. More insidious is that insulin resistance also creates a “fat trap” through which incoming dietary calories are trapped in your fat cells and can’t be released to provide the necessary energy the body needs. This means you are constantly hungry.

If you are surrounded by cheap processed foods (rich in omega-6 fatty acids and refined carbohydrates), then you are going to quench that hunger with those foods that increase cellular inflammation to even greater levels. The end result is an increasing rise of obesity.

But the fastest growing segment of the overweight and obese population is not adults, but children under the age of 5, with 20 percent now either overweight or obese before entering kindergarten (2). You can’t blame school lunches for this because they are not in school yet. What you can blame is epigenetics (3). This is how the metabolic future of the child can be greatly determined in the womb by the inflammatory nature of the mother’s diet. When these children are born, their altered genetics make them sitting targets for a world full of inflammatory food. Unless you change the foundation of the food supply to become more anti-inflammatory (less omega-6 fatty acids and a lower glycemic load), then the future for these children is incredibly bleak.

The key to a healthy gut

Most people think all you need for a healthy gut is to consume bacterial-fortified yogurt products. In reality, the balance of bacteria in your gut may hold a key toward managing systemic inflammation in our bodies.

First of all, there are a lot of bacteria in our guts. The human body contains about 100 trillion cells, but the number of bacteria in the gut is 10 times greater in number. Furthermore, these bacteria are not just taking up space; they are actually providing numerous useful functions that make them a symbiotic “organ” to our own body. In particular, they can ferment carbohydrates to provide additional energy, make various vitamins, break down toxins we might ingest, and help prevent the growth of pathogenic bacteria.

Although there are literally millions of different bacteria in the world, only about 500 species actually reside in our guts. We also know that these gut bacteria can be further divided into three distinct bacterial ecosystems (1). Just like there are four unique blood groups that can classify every human, we also have three distinct bacterial systems. Once one of these systems becomes established in the gut, it begins to alter the gut environment that only certain species of other bacteria can follow and safely begin their symbiotic relationship with us.

So how does each ecosystem of bacteria keep out the bad apples (like Salmonella)? First of all, the bacteria in each distinct ecosystem have to alert our own immune cells in the intestine that they are friends, not foes. Apparently they have learned how to suppress the immune system in our own cells so they can co-exist in our gut (2). However, I believe even though these ecosystems of bacteria can be recognized as friends and not foes, they still need unique nutrients to help them act as the first line of defense against millions of other harmful bacteria.

Those nutrients are polyphenols. In the plant world, these polyphenols act as antibiotics against microbial attack. There is evidence that the “good” bacteria in our gut can use them as a means to help ward off invading bacteria that threaten our own unique bacterial fingerprint. Of course, the only way we can continue to help our unique bacterial partners in our gut is to continue to eat lots of fruits and vegetables that are rich in polyphenols. That’s why your grandmother told you to eat an apple a day to keep the doctor away.

Zone diet validation studies

Weight Loss

Any diet that restricts calories will result in equivalent weight loss. However, the same doesn’t hold true as to what the source of that weight loss is. Weight loss from either dehydration (such as ketogenic diets) or cannibalization of muscle and organ mass (such as low-protein diets) has no health benefits. Only when the weight loss source is from stored fat do you gain any health benefits. Here the Zone diet has been shown to be superior to all other diets in burning fat faster (1-4). It has been demonstrated that if a person has a high initial insulin response to a glucose challenge, then the Zone diet is also superior in weight loss (5,6). A recent study from the New England Journal of Medicine indicates that a diet composition similar to the Zone diet is superior to other compositions in preventing the regain of lost weight (7). This is probably caused by the increased satiety induced by the Zone diet compared to other diets (1,8,9).

Reduction of cellular inflammation

There is total agreement in the research literature that the Zone diet is superior in reducing cellular inflammation (10-12). Since cellular inflammation is the driving force for chronic disease, then this should be the ultimate goal of any diet. Call me crazy for thinking otherwise.

Heart disease

It is ironic that the Ornish diet is still considered one of the best diets for heart disease, since the published data indicates that twice as many people had fatal heart attacks on the Ornish diet compared to a control diet (13). This is definitely the case of don’t confuse me with the facts. On the other hand, diets with the same balance of protein, carbohydrate and fat as the Zone diet has have been shown to be superior in reducing cardiovascular risk factors, such as cholesterol and fasting insulin (14,15).


The first publication validating the benefits of the Zone diet in treating diabetes appeared in 1998 (16). Since that time there have been several other studies indicating the superiority of the Zone diet composition for reducing blood glucose levels (17-20). In 2005, the Joslin Diabetes Research Center at Harvard Medical School announced its new dietary guidelines for treating obesity and diabetes. These dietary guidelines were essentially identical to the Zone diet. Studies done at the Joslin Diabetes Research Center following those dietary guidelines confirm the efficacy of the Zone diet to reduce diabetic risk factors (21). If the Zone diet isn’t recommended for individuals with diabetes, then someone should tell Harvard.

Ease of use

The Zone diet simply requires balancing one-third of your plate with low-fat protein with the other two-thirds coming from fruits and vegetables (i.e. colorful carbohydrates). Then you add a dash (that’s a small amount) of heart-healthy monounsaturated fats. The Zone diet is based on a bell-shaped curve balancing low-fat protein and low-glycemic-index carbohydrates, not a particular magic number. If you balance the plate as described above using your hand and your eye, it will approximate 40 percent of the calories as carbohydrates, 30 percent of calories as protein, and 30 percent of the calories as fat. Furthermore, it was found in a recent Stanford University study that the Zone diet provided greater amounts of micronutrients on a calorie-restricted program than any other diet (22).

Eventually all dietary theories have to be analyzed in the crucible of experimentation to determine their validity. So far in the past 13 years since I wrote my first book, my concepts of anti-inflammatory nutrition still seem to be at the cutting edge.
