The Four Critical Cardiovascular Disease Risks That You Can Change

Welcome to Weekly Health Update



New research shows that high blood pressure, high cholesterol, diabetes, and smoking account for the vast majority of all deaths caused by cardiovascular disease.


 

THE FOUR CRITICAL CARDIOVASCULAR DISEASE RISKS THAT YOU CAN CHANGE

As I mention in my recent bestselling book, A Cancer Prevention Guide for the Human Race, many of the very same lifestyle and dietary habits that increase our risk of developing cancer also increase our risk of developing cardiovascular disease, including coronary artery disease, heart attacks (myocardial infarction), peripheral vascular disease, and stroke.  Likewise, adopting an evidence-based cancer prevention lifestyle can not only cut your cancer risk in half, but can also significantly reduce your risk of developing life-threatening cardiovascular disease as well.

A newly published research study, which was funded by the National Institutes of Health, provides, for the first time, a comprehensive assessment of the lifetime risks of developing cardiovascular disease based upon the following four health-related factors: blood pressure, cholesterol (lipid) levels in the blood, smoking status, and diabetes status.  Importantly, this huge meta-analysis study, which appears in the current issue of the New England Journal of Medicine, comprehensively analyzes the data from 18 different prior clinical research studies, which included 257,384 adult black and white men and women.  These research volunteers were assessed for these four critical cardiovascular risk factors every 10 years, beginning at age 45 and ending at age 75.  This enormous group of research volunteers was then closely followed, and the incidence of cardiovascular disease and death rates due to cardiovascular disease were then carefully evaluated and analyzed.

When looking at cardiovascular risks factors at age 55 as predictors of future cardiovascular disease risk, and the risk of death due to cardiovascular disease, the findings of this extremely large clinical study were striking.  In this study, a low-risk profile for cardiovascular disease was defined as total blood cholesterol less than 180 milligrams per deciliter (4.7 mmol per liter), average blood pressure less than 120/80 millimeters of mercury (mm Hg), nonsmoker status, and nondiabetic status.

Among the 55 year-old men and women who met all of the criteria for a low-risk profile for cardiovascular disease, their lifetime incidence of cardiovascular disease, through age 80, was remarkably lower than for the 55 year-olds who failed to meet two or more of the four low-risk criteria.  In fact, the risk of death due to cardiovascular disease, through age 80, was only 5 percent among the men who met all four low-risk criteria at age 55, while the men who met only two or fewer low-risk criteria faced a dramatic six-fold increase in the risk (30 percent) of dying of cardiovascular disease by age 80.  Among the women volunteers, only 6 percent of the women who met all four low-risk criteria went on to die of cardiovascular disease by age 80, while 21 percent of the women who failed to meet two or more of the four low-risk criteria died of cardiovascular disease between age 55 and age 80 (for a nearly four-fold increase in the risk of death).

Fatal and nonfatal coronary artery disease occurred in only 4 percent of the men who met all four low-risk criteria, but occurred in nearly 10 times as many of the men (38 percent) who failed to meet two or more of these four criteria.  The women who met all four low-risk criteria faced a less than 1 percent risk of fatal and nonfatal coronary artery disease, while the women who met two or fewer low-risk criteria experienced an 18 percent incidence of fatal and nonfatal coronary artery disease (for a more than 18-fold increase in risk).

The risk of fatal and nonfatal stroke was also significantly lower among men and women who met all four low-risk criteria for cardiovascular disease.  Among the men who met all four low-risk criteria, the incidence of stroke through age 80 was only about 2 percent, but quadrupled, to more than 8 percent, among the men who failed to meet two or more of the four low-risk criteria.  Among the women who met all four low-risk criteria, the incidence of stroke was about 5 percent, but more than doubled, to nearly 11 percent, among the women who failed to meet at least two of the low-risk criteria.

The findings of this very large study cannot be overstated in terms of its public health importance, as this is the only study that has prospectively assessed very large numbers of men and women, including both black and white adults, over long periods of time, and that has analyzed the long-term impact of the four most common risk factors for cardiovascular disease on incidence and death rates associated with cardiovascular disease.  As with the studies that I discuss in A Cancer Prevention Guide for the Human Race, the impact of lifestyle, diet, and other modifiable health-related factors on both cardiovascular disease risk and cancer risk is enormous, particularly when measured over the lifespan of the average adult.

The findings of this epic public health research study also add further weight to my strong belief, based upon my review of thousands of research studies, that we, as individuals, hold the key to improving our health, and to significantly reducing our risk of serious illness and premature death, by living evidence-based healthy lifestyles.  If your blood pressure is high, change your diet and increase your level of exercise, with the support of your doctor.  If diet and physical activity interventions alone do not correct your hypertension, then ask your doctor about medications for high blood pressure.  If you have diabetes, you also need to change your diet, increase your levels of physical activity, and safely lose any excess weight.  If these lifestyle changes do not completely resolve your high blood sugars, then you may also need to ask your doctor about medications for diabetes.  If you smoke, or use smokeless tobacco, stop immediately.  Finally, if your LDL and total cholesterol levels are high, then, once again, you need to be more careful about what you eat.  (The cancer-preventing foods and diets that I discuss in my book have also been linked to lower levels of blood cholesterol, as well as a much lower risk of cardiovascular disease.)  You may also need to increase your physical activity levels, and get your weight down to a healthy level, to improve your LDL and total cholesterol levels.  Once again, if these prudent lifestyle measures are not enough, by themselves, to bring your cholesterol levels down into the normal range, then your doctor may need to add a cholesterol-lowering medication as well.

The striking results of this important cardiovascular disease prevention study provide all of us with the key to maximally reducing our risk of developing—and dying from—largely preventable cardiovascular diseases, including heart disease and stroke.  Better long-term health (and a longer and more vigorous life) is within your grasp, and this study, in addition to my book, can show you the way forward.

Orlistat (Alli or Xenical) Significantly Reduces Obesity

Welcome to Weekly Health Update


New research suggests that the over-the-counter drug orlistat can significantly improve weight loss when combined with a low-fat diet.



ORLISTAT (ALLI or XENICAL) SIGNIFICANTLY REDUCES OBESITY

Approximately two-thirds of the population in the United States is overweight, while at least a third of all people are obese.  Excess weight has clearly been linked to serious illnesses, including high blood pressure (hypertension), diabetes, cardiovascular disease, lung disease, liver disease, gallstones, and arthritis, among other potentially life-threatening ailments.  As I note in my book, A Cancer Prevention Guide for the Human Race, the extremely high concentration of fat and calories in modern processed foods, when combined with the sedentary lifestyles that most of us lead, almost guarantees a high level of obesity in our population.

Orlistat, which is available in both prescription and non-prescription forms, blocks the activity of lipase, an enzyme within the GI tract that breaks down dietary fats so that they can be absorbed.  Previous clinical research studies have shown that the addition of orlistat to a low-fat diet can significantly reduce body fat, and, in turn, can reduce the risk of illnesses that are associated with obesity.  Now that orlistat is available without a prescription, there have been concerns that this medication may be less effective, as it can now be purchased and taken without first having to enroll in a structured weight loss program.

A newly published study, which appears in the European Journal of Clinical Nutrition, suggests that non-prescription doses of orlistat (trade names Alli and Xenical) may still be an effective addition to the standard weight loss strategies of a healthy low-fat diet and exercise.  In this study, 27 obese research volunteers took over-the-counter orlistat (60 milligrams three times a day, with meals) for three months.  At the beginning and end of this study, the 27 volunteers were subjected to specialized imaging tests, including MRI scans, to measure the amount of fat in their bodies.  Blood pressure, heart rate, and cholesterol levels were also assessed.

In this clinical study, the use of over-the-counter orlistat, in combination with a reduced calorie, low-fat diet, was associated with a significant 11 percent reduction in body fat after 3 months.  Moreover, cholesterol levels, blood pressure, and heart rate all decreased, as well, following three months of orlistat combined with a prudent diet.

The findings of this study suggest that even over-the-counter orlistat, in conjunction with healthy eating habits, can significantly reduce both body fat and at least some of the adverse health effects associated with obesity.

Now for the bad news… orlistat works by blocking the absorption of fat from the GI tract, which means that 25 to 30 percent of the fat consumed while taking orlistat will remain within the GI tract until it is eliminated in the feces.  Unfortunately, high levels of undigested fat in the stool can lead to some rather unsettling symptoms, including flatulence, greasy/oily stools, bloating, and in some patients, an urgent desire to have a bowel movement.  On the other hand, while these symptoms are very common during the first few months of orlistat use, they appear to improve over time, such that only about one-third of patients taking orlistat will still have these symptoms four years after starting the drug.  Moreover, in patients who conscientiously maintain a low-fat diet while taking orlistat, the incidence and severity of these GI tract side effects are even lower.  (Another potential complication of orlistat is the reduced absorption of the fat soluble vitamins A, D, E, and K, although vitamin supplements will prevent significant deficiencies of these vitamins.)

While orlistat is associated with significant potential side effects, and thus should not be taken by everyone, the results of this small study do strongly suggest that orlistat is an effective option for obese patients who are able to both tolerate the drug’s side effects and remain compliant with a low-fat diet.  As always, however, I strongly recommend that you check with your primary physician prior to starting any new diet or medication, including orlistat.

New Research Says that Chocolate DECREASES Cardiovascular Disease Risk and Diabetes


Welcome to Weekly Health Update



New research suggests that moderate chocolate consumption can significantly decrease the risk of heart disease, stroke, and diabetes.



NEW RESEARCH SAYS THAT CHOCOLATE DECREASES CARDIOVASCULAR DISEASE RISK AND DIABETES

Cocoa, from which chocolate is made, is known to be rich in flavonol antioxidants, as well as other compounds that appear to reduce the risk of developing the cholesterol plaques that cause coronary artery disease, stroke, and peripheral vascular disease. Cocoa has also been shown to improve the function and health of critical blood vessels in the body, which can lower elevated blood pressure. Moreover, additional research has shown that cocoa may also decrease the risk of diabetes.

Milk chocolate contains considerably more fat and sugar than dark chocolate, and these milk chocolate additives are well known to increase the risk of obesity, diabetes, and cardiovascular disease. Therefore, dark chocolate has been more often recommended than milk chocolate as a possibly healthy treat. However, several public health studies have suggested that even milk chocolate may still possess clinically significant cardiovascular health benefits, despite its high fat and high sugar content.

A newly published meta-analysis study, which appears in the British Medical Journal, adds weight to the possibility that even milk chocolate might have heart-healthy properties. In this meta-analysis study, seven previously published public health research studies, which included 114,009 research volunteers, were analyzed. This analysis revealed that 5 of these 7 previously published public health studies found that increased chocolate consumption was associated with a significant decrease in the risk of cardiovascular disease and diabetes. Specifically, research volunteers who reported the highest levels of chocolate consumption were observed to be 37 percent less likely to develop heart disease, 31 percent less likely to develop diabetes, and 29 percent less likely to have a stroke when compared to the volunteers who reported the least chocolate consumption.

Now, for the (possibly) bad news….  None of these seven public health research studies were randomized clinical research studies.  All were so-called “observational” studies, wherein groups of volunteers completed questionnaires regarding their diet and lifestyle habits, and were then observed over time for the development of new health problems.  The obvious weakness of observational studies, in general, is their reliance upon the often inaccurate self-reporting by research volunteers on questionnaires designed to assess their dietary and lifestyle habits.  The other weakness of these particular research studies is that they did not identify which types of chocolate were associated either with the least or the greatest health benefits (nor is it clear from these studies whether or not there is an optimal amount of chocolate intake necessary to produce the greatest possible health benefits).  All of these important disclaimers aside, multiple clinical research studies have previously shown very significant potential health benefits associated with regular chocolate consumption.  At the same time, in view of the clear association of increased fat and sugar intake with obesity, diabetes, high blood pressure, and cardiovascular disease risk, among other health problems, my recommendation to my patients and readers is to take moderate amounts of dark chocolate, and other lower-fat and lower-sugar chocolates, as part of a heart-healthy lifestyle!

Lifestyle and Diet Modifications Reduce Erectile Dysfunction (ED)

Welcome to Weekly Health Update



New research suggests that the same lifestyle and diet choices that reduce cardiovascular disease risk also reduce the risk of erectile dysfunction (ED) in men, and improve male sexual function.



LIFESTYLE AND DIET MODIFICATIONS REDUCE ERECTILE DYSFUNCTION (ED)

As I discuss in my book, A Cancer Prevention Guide for the Human Race, evidence-based lifestyle and diet modifications can dramatically reduce your lifetime risk of developing cancer, including some of the most deadly forms of this disease.  As an “added benefit,” many of the same lifestyle and diet modifications that I discuss in my book have also been shown to reduce the risk of cardiovascular disease, as well.  Moreover, previous research studies have suggested that the risk of male sexual dysfunction, and erectile dysfunction (ED) in particular, might also be reduced by living a heart-healthy lifestyle.

The most important risk factors for sexual dysfunction in men, and ED in particular, include heart disease, peripheral vascular disease, elevated blood cholesterol, high blood pressure, diabetes, smoking, obesity, and sedentary behavior. Since the risk of these serious health problems can all be significantly reduced through lifestyle and diet modification, it is worth asking whether or not evidence-based lifestyle modifications associated with a reduced risk of cardiovascular disease and diabetes can also significantly reduce the risk of ED. A newly published research study, which appears in the current issue of the Archives of Internal Medicine, provides important new insights into this serious men’s health issue.

In a meta-analysis of 6 previously published prospective randomized clinical research studies, 740 adult male research study volunteers were evaluated. In this group of men, heart-healthy changes in diet, physical activity, and other modifiable lifestyle factors were associated with a highly significant improvement in sexual function when compared to similar-aged men who did not modify their lifestyle and diet. (Moreover, the addition of cholesterol-lowering statin drugs in men with elevated blood cholesterol levels improved sexual function even further than lifestyle and diet modifications, alone.)

Too many men continue to refuse to change their unhealthy lifestyles and dietary habits, and so they face an increased risk of cardiovascular disease, obesity, diabetes, high blood pressure, and other largely preventable diseases.  However, sexual function is such a very important quality-of-life factor for most men that it is my hope that studies such as this one will get the attention of men who are still living unhealthy lifestyles that increase their risk of ED and other preventable serious illnesses.  Also, as ED is now known to be an early warning sign of cardiovascular disease, diabetes, and other preventable lifestyle-associated diseases in men, modifying your lifestyle and diet to reduce your risk of ED will also significantly reduce your risk of these other life-threatening diseases at the same time (and cancer, as well)!

Dietary Fiber Significantly Reduces Risk of Death

Welcome to Weekly Health Update


“A critical weekly review of important new research findings for health-conscious readers”



 

Dietary Fiber Significantly Reduces Risk of Death

Most of us already know that a high-fiber diet is an important part of a healthy lifestyle. Numerous previous research studies have associated a high-fiber diet with a decreased incidence of cardiovascular disease, diabetes, and some forms of cancer. However, there is very little research information available that directly links a high-fiber diet with a decreased risk of death from these or other diseases. Now, a newly published public health study puts some actual numbers on the potential health benefits of adding fiber to your diet. This study appears in the current issue of the Archives of Internal Medicine.

The NIH (National Institutes of Health)-AARP Diet and Health Study is an enormous prospective public health study, which has enrolled 219,123 men and 168,999 women between the ages of 50 and 71 years. All of these research study participants completed extensive dietary questionnaires, and all were closely followed for an average of 9 years.

During nearly a decade of follow-up, 20,126 men and 11,330 women participating in this study died of various causes. When the researchers compared the dietary fiber intake of the volunteers who died with those who did not die, several important findings were identified. High levels of dietary fiber intake appeared to decrease the risk of death for both men and women by about 22 percent, overall. A diet rich in fiber was also specifically linked to a significant reduction in the risk of death due to cardiovascular disease, infection, and respiratory disease in both men and women; while men (but not women) appeared to have a lower risk of death due to cancer if they consumed a fiber-rich diet. Finally, as has also been found in previous diet-based studies (including several of the Mediterranean diet studies that I cite in my book, A Cancer Prevention Guide for the Human Race), dietary fiber from whole grains appeared to provide the greatest benefit in terms of reducing the risk of death due to all causes.

While this study suffers from the same limitations as all other survey-based public health studies, its prospective methodology and its enormous population of research volunteers make this a very powerful public health study. Its finding that a diet rich in fiber (derived from whole grains) significantly reduces the risk of death from the most common global causes of death offer all of us an important strategy to improve our health and longevity.

Dietary Salt (Sodium) Increases Stomach Cancer Risk

 

Welcome to Weekly Health Update


“A critical weekly review of important new research findings for health-conscious readers”


DIETARY SALT (SODIUM) INCREASES STOMACH CANCER RISK

 

Cancer of the stomach occurs only about half as commonly today in the United States as it did 30 years ago, but it remains one of the “bad actor” cancers that are associated with a high likelihood of death.  On a global scale, stomach cancer remains the #2 cause of cancer-associated death, while in the United States, gastric cancer is currently the #7 cause of cancer-associated death.

Known risk factors for stomach cancer include chronic infection with the Helicobacter pylori bacterium (and other causes of chronic gastric inflammation), smoking, obesity, decreased acid secretion within the stomach, stomach ulcers, pernicious anemia, a family history of stomach cancer, certain inherited cancer syndromes, and other less common risk factors.  As with other GI tract cancers, diet also appears to play an important role in gastric cancer risk.  For example, gastric cancer is more common among people who eat a lot of processed meat and red meat, smoked foods, and salt-cured or pickled foods.  On the other hand, stomach cancer is less common among people who consume a large amount of fresh fruits and vegetables.

The role of salt in gastric cancer risk has been a subject of some debate, as clinical research studies have come to varying and contradictory conclusions regarding this issue.  However, a newly published public health study, which appears in the current issue of the British Journal of Cancer, appears to strongly link excess salt consumption with an increased risk of developing stomach cancer.  In this case-control study, 442 patients with stomach cancer, and 649 healthy patients without any clinical evidence of cancer, were evaluated.  Multiple previously validated dietary questionnaires were administered to all of the study volunteers, with particular attention to dietary salt intake. 

The results of this public health study indicated that the risk of stomach cancer was twice as common among patients who regularly consumed the highest amounts of salt, when compared to patients with the smallest amount of regular salt intake.  After adjusting for other risk factors known to be associated with gastric cancer risk (including Helicobacter pylori status, smoking history, and other known gastric cancer risk factors), increased salt intake was still associated with a doubling of gastric cancer risk. 

While case-control studies, such as this one, do not offer high-level clinical research evidence (unlike the “gold standard” prospective, randomized, blinded clinical research trials that provide “Level 1” clinical research data), the findings of this observational study nonetheless add to an increasing volume of data linking increased salt intake with gastric cancer risk.

Excessive salt intake has also been clearly linked to a significant increase in the risk of high blood pressure, stroke, and cardiovascular disease.  Most hypertension experts are currently recommending that we lower our average daily intake of sodium, from the current 3,500 to 4,000 milligram (mg) per day level in the United States, to somewhere around 1,500 mg per day.  At this level of sodium intake reduction, significant improvements in high blood pressure, and in the risk of stroke and cardiovascular disease, have been demonstrated by multiple high-quality clinical research studies.  (An excellent pamphlet on the topic of dietary sodium reduction, as part of a heart-healthy diet, has been published online by the National Institutes of Health.)    

As with many other dietary and lifestyle factors that have been shown to reduce cancer risk, reducing sodium intake, by reducing your dietary salt consumption, can pay big health dividends not only in terms of cancer risk reduction, but also in terms of reducing those other great global killers of mankind, cardiovascular disease and stroke!

Hesperidin in Orange Juice Improves Hypertension and Arterial Function

 

Welcome to Weekly Health Update


“A critical weekly review of important new research findings for health-conscious readers”


HESPERIDIN IN ORANGE JUICE IMPROVES

HYPERTENSION AND ARTERIAL FUNCTION

 

Polyphenols are chemical compounds that are found in most of the plant-based foods that we commonly eat.  As I discuss in detail in my new book, A Cancer Prevention Guide for the Human Race, some polyphenolic compounds, such as green tea flavonoids, soy-based isoflavones, quercetin, curcumin, and resveratrol, among other polyphenols, may possess important cancer prevention properties.  There is also abundant research data suggesting that diets rich in certain natural dietary polyphenols may be associated with a decreased risk of cardiovascular disease, as well.

Hesperidin, which is a flavonoid polyphenol, is found in a variety of plant-based foods, including oranges, orange juice, and other citrus fruits.  A newly published prospective, randomized, blinded clinical research study, which appears in the current issue of the American Journal of Clinical Nutrition, offers intriguing evidence that hesperidin may actually decrease the risk of cardiovascular disease in high-risk patients.

In this pilot study, 24 overweight (but otherwise healthy) men, ages 50 to 65 years, were subjected to 4-week intervals in each of three experimental groups.  The first group was assigned to drink 500 ml (17 ounces) of orange juice per day.  The second experimental group drank a “control drink” that appeared similar to orange juice, but which did not contain any actual orange juice.  However, this “sham orange juice” was fortified with hesperidin.  The third group was also assigned to drink the fake orange juice, and to which was added a supplement portrayed (to the study volunteers, and to the research nurses who administered the beverages to these research volunteers) as hesperidin, but which, in fact, was an inert placebo that contained no hesperidin or other polyphenols.

Physical examinations and blood tests were performed before and after the men rotated through each of these three experimental groups.

The findings of this small but high quality clinical research study were quite interesting.  When compared to the control group that consumed the fake orange juice and fake hesperidin supplement, the men in the other two experimental groups experienced a significant reduction in their blood pressure measurements.  Specifically, the diastolic blood pressure was significantly reduced, which suggests that these men experienced an improvement in the elasticity, or compliance, of their arteries, as a direct result of the hesperidin contained in both orange juice and in the non-juice beverage supplemented with hesperidin.  This observation was again confirmed through additional testing that revealed improved vascular compliance associated with hesperidin intake.  Moreover, this significant improvement in arterial compliance was observed only after the ingestion of hesperidin, and disappeared when these same men were retested after undergoing an overnight fast.  (Improved arterial compliance is associated with a reduced risk of cardiovascular disease, including high blood pressure, coronary artery disease, and stroke.)

To summarize the findings of this study, hesperidin, when taken in the form of either orange juice or as a supplement, appeared to significantly improve arterial elasticity, and lower diastolic blood pressure, in middle-aged overweight men.  While this brief study cannot prove that these observed and transient improvements in arterial compliance subsequently reduced the incidence of cardiovascular disease in these high-risk men, there is abundant data from other research studies linking improved arterial compliance with a reduced incidence of cardiovascular disease.  A much larger version of this small pilot study should now be repeated, and the volunteers in this larger study need to be followed for a much longer duration of time, before we can say, with certainty, that hesperidin significantly reduces the risk of cardiovascular disease.  That being said, the findings of this small but well-conducted, and elegant, randomized, controlled, prospective clinical research study are still quite compelling.

Blueberries, Obesity, Diabetes and Metabolic Syndrome

 

Welcome to Weekly Health Update


“A critical weekly review of important new research findings for health-conscious readers”


BLUBERRIES, OBESITY, DIABETES AND METABOLIC SYNDROME

Metabolic syndrome includes a constellation of health disorders that are associated with a high risk of developing diabetes and cardiovascular disease.  Specific disorders that are associated with metabolic syndrome include high blood pressure, abnormal cholesterol and triglyceride levels in the blood, obesity, and diabetes (or “pre-diabetes”).  In the United States, where obesity has become an epidemic, public health experts estimate that as much as 25 percent of the population currently meets the criteria for metabolic syndrome.

Excessive calorie intake, a sedentary lifestyle, obesity in the abdominal and waist areas (central, or visceral, obesity), genetic factors, and other adverse health risks are known to contribute to the development of metabolic syndrome.  Therefore, both the prevention and treatment of metabolic syndrome are based upon exercise, a healthy low-fat and low-sugar/low-carb diet, and weight loss.  A new prospective, randomized clinical research study suggests that consuming blueberries may also help to reduce some of the adverse health risks associated with metabolic syndrome.

In this study, which appears in the current issue of The Journal of Nutrition, 48 adults (44 females and 4 males) with metabolic syndrome were divided into two groups.  One group, the “experimental group,” consumed 50 grams of freeze-dried blueberries per day (equivalent to 350 grams of fresh blueberries per day), in the form of a beverage, for a period of 8 weeks.  The other group, the “control group,” consumed a “placebo” beverage that did not contain any blueberries (also for 8 weeks).  Blood pressure checks and multiple blood tests were performed at both 4 weeks and 8 weeks into the study.

When comparing the two groups of patient volunteers, the patients in the “blueberry group” were found to have significantly greater decreases in their high blood pressure when compared to the control group.  The level of oxidized LDL cholesterol in the blood, which is a form of the “bad” LDL cholesterol that can directly damage the lining of arteries throughout the body (atherosclerosis), was also significantly decreased in the “blueberry group” of patient volunteers.  At the same time, there were no significant differences between the two groups of patient volunteers with respect to blood glucose (sugar) levels, triglyceride levels, or the levels of HDL (the “good” cholesterol) or LDL (the “bad” cholesterol) in the blood .

Therefore, while a brief period of a diet supplemented with blueberries did not reverse all of the abnormalities associated with metabolic syndrome, the consumption of the equivalent of about 350 grams of blueberries each day did appear to significantly improve at least two of the adverse health factors associated with this syndrome (i.e., high blood pressure and blood levels of oxidized LDL cholesterol).  Based upon the intriguing findings of this small and short-duration study, patients with one or more health factors associated with metabolic syndrome might consider adding some blueberries to their daily diet, in addition to the standard treatment for this life-threatening disorder!

 

For more information on blueberries, and other sources of dietary polyphenols, as part of a cancer prevention lifestyle, watch for the publication of my new landmark evidence-based book, “A Cancer Prevention Guide for the Human Race,” in September of this year.
