Guest guest Posted March 21, 2005 Report Share Posted March 21, 2005 Is a Little Wine Good for the Heart?- JoAnn Guest Mar 21, 2005 15:19 PST Part 1: A Scientific Perspective Many of you have heard or read that moderate alcohol may be beneficial to your health. Here is an example of a New York Times press release printed on December 11, 1997. " STUDY FINDS DRINK A DAY KEEPS THE GRIM REAPER AWAY " . It stated that " researchers report that modest drinking is, on balance, healthful and alcohol's ill effects are offset by alcohol's benefit to the heart. " As a physician, it was important to me to go to the scientific literature myself to examine the evidence before I would start advising patients, as some doctors have, that alcohol be used for medicinal purposes. First, I obtained the original research paper printed in the New England Journal of Medicine, December 1997 and then I did a literature search of all the articles that have been published on alcohol in the last three years. What I found was quite surprising, considering all the popular press coverage of the beneficial and medicinal properties of alcohol. The largest and longest study to date was published in the " New England Journal of medicine " in December 1997 and was entitled " Alcohol Consumption and Mortality among Middle-aged and Elderly U.S. Adults " . (Thun et al., NEJM 1997; 337: 1705-14). It followed nearly 500,000 individuals for nine years and reported a 20% decrease in mortality for those aged 35 to 70 during the study period for those who consumed at least one alcoholic beverage per day as compared to non drinkers. They attributed nearly all of the lower death rates to medicinal effects of alcohol in protections against cardiovascular disease. From a purely medical point of view should physicians start recommending alcohol consumption to protect against heart disease and to promote good health? Many people have interpreted these findings to suggest moderate drinking of alcoholic beverages should be part of a healthy lifestyle. After carefully studying the original research paper from the New England Journal of Medicine (NEJM) plus reviewing over fifty other alcohol related articles published in the medical literature in the last three years, the following seven points should be considered before using alcohol for medicinal purposes: Alcohol is a well-established risk factor for numerous cancers. The NEJM study showed a 30% increase in breast cancer in women consuming as little as 1 drink per day. This added to the already known increased incidence of mouth, throat, esophagal, stomach, pancreatic and liver cancer associated with alcohol consumption. (Rosener L. " Alcohol consumption and the risk of breast cancer. " Epidemiology Review 1993: 15:133-44). The only reason that an overall decreased mortality rate was shown in the alcohol drinking population was because many more people die from heart disease than cancer. How could any physician face a patient dying a slow, painful death from a cancer clearly linked to the alcohol that had previously been recommended as a way to decrease the chance of a heart attack by only 30% when other less risky preventative measures are available without causing cancer as a side effect? By analysing only those aged 35 to 70, the study did not accurately reflect the lifetime risk of alcohol consumption. Alcohol related injury is the number one cause of death in the 15 to 30 years old age group. (McGinnis, J.M. " Actual causes of death in the United States " , Journal of the American Medical Association, 1993; 279:2207-12) The mechanism by which alcohol gives cardiac protection may be harmful to other body systems. Alcohol appears to protect against heart attack in two ways. First, by raising the level of HDL cholesterol which reduces the build up of atherogenic plaque in the blood vessels, and secondly, by acting as a " blood thinner " which clots from forming in the already narrowed coronary arteries which is the initial event in most heart attacks. (Kannel, WB. " Serum cholesterol, lipoproteins, and the risk of coronary heart disease " , The Framingham Study, Ann Int Medicine 1971: 38: 1224-32). Interfering with the delicate balance in the blood clotting mechanism may be a dangerous thing. A few years ago, it was noted that aspirin had blood thinning properties that prevented heart attacks. The initial reports were so impressive that thousands of physicians voluntarily started taking aspirin daily as a part of a study to look at the long term benefits. The research project was stopped " prematurely " when it was noted that the *aspirin group* was experiencing an unexpectedly high " incidence " of *hemorrhagic stroke*. While trying to prevent a heart attack by thinning the blood, some of these doctors died, or were permanently disabled by bleeding into their brains. Now most doctors only recommend aspirin to patients who have already had one heart attack. The reasoning being that the risk of a second heart attack is greater than the aspirin induced stroke and the " potential benefit " outweights the risk. ????? It clearly points out the danger of interfering, as alcohol does, with the delicate balance of the body in such areas of blood clotting. In addition, while preventing certain types of heart disease, alcohol has been clearly " linked " to *cardiac arrhythmias* and *cardiomyopathy* leading to congestive heart failure. (Cowie, M.R. " Alcohol and the heart " British Journal of Hospital Medicine, 1997; 57: 548-51). The 30% decrease in the death rate from heart disease attributed to alcohol may be achieved and surpassed by other much less risky methods. Numerous studies have shown that simple lifestyle measures can reduce cardiac risk by 50 to 70% without any of the many harmful side effects documented with alcohol usage. (Miller, G.J. " Alcohol consumption: protection against coronary disease and risk to health. " Int. Journal Epidemiology, 1990; 19:923-30) The study methodology and analysis bring into question the validity of the conclusions. It must be understood that all studies relating health risk and alcohol consumption rely on voluntary questionnaires being accurately completed. No one actually follows the patients around to document their consumption or verify their claims. One of the editors of the NEJM who wrote an editorial response pointed out that the study group reported their yearly alcohol consumption to be only half of US government per capita estimates based on industry production and sales. (Potter, J.D. " Hazards and benefits of alcohol " . NEJM 1997: 337: 1763-64). He pointed out that either this study group did not reflect average American drinking habits, or they did not accurately complete their questionnaires. (A third possibility which he did not mention would be that one half the alcohol produced in this country gets poured down the drain or is used to kill slugs). Anyone who has ever worked with alcoholics knows they are often in denial regarding their drinking patterns and some may have inaccurately placed themselves in the non-drinking groups statistics which would affected the validity of the conclusions. Additionally, the NEJM study excluded from their statistics without explanation 32,000 individuals who had cancer or cirrhosis at the start of the study. These diseased are known to be closely linked to alcohol consumption and their exclusion could markedly effect mortality rates. Apart from the heart, alcohol has physiologic negatives on virtually every major body system. When reading in the lay press one could easily conclude that most medical research in recent years has focused on the positive medicinal value of alcohol on the heart. In reality, a totally different picture emerges. A computer research of all English language research papers in the scientific literature in the last three years revealed 355 published articles of which 48 were review articles. Review articles summarize and condense research findings on a related topic. After carefully reading the abstracts of the 48 review articles, 44 were clearly dealing with the " toxic affects " of alcohol and of the remaining 4 which death with the cardiac benefits each clearly included in the negative side effect. Here is only a sampling of statements taken from these abstracts. " Alcohol is a neurotoxin associated with significant morbidity and mortality...it may raise blood pressure, damage the myocardium, precipitate arrhythmias and damage the developing fetal heat. " (Sceepers, B.C. " Alcohol and the Brain. " British Journal of Hospital Medicine, 1997; 57: 543-51) " It is well recognized that alcohol increases the risk of injury. " (Guohua, L. " Alcohol and injury severity. " Journal of Trauma 1997; 42:562-69) " Alcohol can lead to potentially hazardous hypoglycemia... " (Meeking, D.R. " Alcohol ingestions and glycemic control. " Diabetic Medicine 1997; 14:279-83) " ...alcohol related problems include liver disease, dementia, confusion, peripheral neuropathy, insomnia, seizure disorders, poor nutrition, incontinence, diarrhea, myopathy, inadequate self care, macroaocytosis, depression, fractures, and adverse reactions to medications. " (Fink, A. " Alcohol related problems in older persons. " Archives of Internal Medicine 1997; 157:242-3). " Alcohol has consistently been related to risks of sqaumous cell cancer... " (Thomas, D.B. " Alcohol as a cuase of cancer. " Environmental Health Perspectives 1995; 103:153-60) " The influence of alcohol on sexual behavior is part of popular knowledge. " (Donovan, C. " A review of the literature examining the relationship between alcohol use and HIV related sexual risk-taking in young people. " Addiction 1997; 90:319-2 Other studies showed the relationship between alcohol and osteoporosis, chronic gastritis, peptic ulcers, decreased immune response, aggressive behavior, fetal malformation, spontaneous abortion and this is only a sampling! It is difficult to see how anyone could review the data and conclude that the beneficial properties of alcohol outweighs the toxicology even when taken in moderate amounts. One must consider the addictive potential of alcohol with its resultant social and economic implications. It is recognized that approximately 10% of the individuals who begin drinking will become sufficiently addicted to be considered problem drinkers or alcoholics. In a Gallup poll, 1out of 4 American report their families being negatively impacted by alcohol abuse. The economic loss of worker productivity is measured in the billions of dollars. A medical pharmacology textbook states: " Alcohol is discussed here separately because its wide and abuse leads to more behavioral and organic toxicity than any other agent. The social and therapeutic problems thus generated are an unavoidable concern of every practitioner...Ethyl alcohol is an addictive drug and it would no doubt immediately be placed under the jurisdiction of the Food and Drug Adminisration, if it were first discovered today. " (Meyers, F.H. Review of Medical Pharmacology. Lange 1980; 242-46) In conclusion, let's suppose you went to your physician and were offered a medication with the following informed consent: " This is a drug which can reduce your chance of heart attack by 30%, but I must warn you that this drug is a direct brain and liver " toxin " . It will increase your chance of contracting cancer, contribute to osteoporosis, ulcers, and hypertension. There's also a 5-10% chance that you will become hopelessly addicted to this drug which could easily lead to losing your job and destroy your marriage. I must also inform you that there are some essential risk-free alternatives that are even more effective in preventing heart disease, but I think you'll really like the " euphoric feeling " you get when you take this drug. " First, the Federal Drug Administration would never allow a drug with this degree of risk-to-benefit profile to ever be marketed. Second, if they did, what patient in their right mind would accept such a prescription and ever trust the judgment of that physician again? It is probably fair to say that many people who claim to be using alcohol for medicinal purposes were already recreational drinkers who were happy to find science supporting their lifestyle. From a purely medical perspective, it is hard to justify it. The medical journal Cardiology Clinics summarizes this as follows: " Given the complex nature of alcohol disease relationships, alcohol consumption should not be considered a primary preventive strategy. " (Gaziano, J. " Diet and Heart Disease: the role of fat, alcohol, and antioxidance. " Cardiology Clinics 1996; 14:69-83) Our decision to drink alcoholic beverages should not be based solely on scientific data, but also on the moral implications. I do not consider my life to be merely a series of chemical reactions which can be tested in lab experiments and reported in the medical literature. Aside from the physiology of my body, I believe my existence has spiritual and mental dimensions which are intricately linked together. Medical science increasingly recognizes that the patient should be treated as a complex being with a intricately connected body, mind, and spirit. Recently, I attended a Harvard Medical School conference entitled " Spirituality and Healing " , which dramatically documented this wholistic view of man. It becomes clear that decisions I make about my body have a major influence on my mental and spiritual dimensions. In Part 2, we will discuss the moral and spiritual implications of alcohol consumption. By Dr. Rick Westermeyer, M.D. Dr. Westermeyer is a practicing physician at the Portland Adventist Medical Centre in Portland, Oregon, U.S.A. http://www.amazingdiet.org/ http://www.geocities.com/mrsjoguest/Botanicals.html ==================================================================== 3 Recent Studies Indicate that the Flavonoids in Red Wine have Beneficial Effects on the Cardiovascular System http://hfn-usa.com/articles/020710-Cardio.html The French smoke, drink and eat lots of cheese. Yet, despite a diet that's relatively high in fat, they boast a 42% lower incidence of cardiovascular disease than Americans do. Why? Because in addition to eating a diet that includes whole, high-fiber grains, they drink red wine. Red wine is chock full of antioxidant compounds, which in turn lowers the risk of blood clots and heart attack.1 Three recent studies have shown that red wine has even more benefits than previously realized. 1) Red Wine Promotes Nitric Oxide Production One study showed that among the many proven benefits of red wine is the inhibition of platelet aggregation and promotion of nitric oxide production, both important factors for promoting proper blood flow throughout the body. Additionally, red wine has been shown to significantly prevent the oxidation of LDL cholesterol. This effect was even evident in heart patients taking large doses of supplemental vitamin E, showing the unique antioxidant properties of red wine components. The authors concluded that, " Based on the existing evidence of antiplatelet and antioxidant benefits and improved endothelial function from red wine and purple grape juice, it seems reasonable to suggest that moderate amounts of red wine or purple grape juice be included among the 5-7 daily servings of fruits and vegetables per day as recommended by the American Heart Association to help reduce the risk of developing cardiovascular disease. " Because red wine seems to have multiple beneficial effects on cardiovascular health and function it seems prudent to include it in our diet. 2) Red Wine Consumption Lowers Homocysteine Levels The newest independent risk factor for cardiovascular disease is excess levels of homocysteine—not cholesterol. Contrary to popular belief, elevated cholesterol alone does not cause heart disease. It is merely one of the many markers of the disease. In fact, it's quite possible to have a heart attack even if you have " normal " cholesterol levels. But, according to research, there's a definite possibility you'll have a heart attack if you have high levels of homocysteine. What is it? Homocysteine is an amino acid derivative that's naturally found in your body. Too much of it can generate free radicals that increase injury to arterial walls, accelerate oxidation and the buildup of cholesterol in blood vessels, and set the stage for arterial and venous diseases, including stroke. 3 The good news is that scientists have discovered that red wine can dramatically lower homocysteine levels, even in obese individuals. These researchers concluded that, " Mild to moderate alcohol consumption, especially red wine consumption, in obese subjects is associated with lower fasting homocysteine concentrations. This may reduce cardiovascular risk and help explain the 'French paradox' " With this new research we can add lowering homocysteine levels to the myriad of positive effects red wine’s components have on cardiovascular health. 4 3) Red Wine Polyphenols Prevent the Oxidation of Dietary Fats in the Digestive Tract While most people are aware that oxidized fats are an important risk factor for cardiovascular disease, most aren’t aware that much of the oxidative stress occurs from the normal oxidation of dietary fats within the digestive tract. The subsequent absorption of these oxidation products greatly increases oxidative damage in the body and modifies LDL cholesterol to damaging forms. Recent research has shown that wine polyphenols are very effective at preventing the rise of oxidized fat products after meals. Because much of our body's oxidative stress is a result of the absorption of these damaging fats after meals, red wine’s unique ability to prevent fat oxidation during digestion is a novel means to lower the damaging effects of these oxidized fats on our cardiovascular system. As the author’s concluded, " Apparently, wine procyanidins are active in preventing lipid oxidation of foods while in the digestive tract, thus preventing the postprandial plasma rise in oxidants. The likely limited bioavailability of these compounds, therefore, does not affect their relevance as key elements for optimizing nutrition and reducing risk of atherogenesis. " 5 Dietary Supplementation is a Popular and Inexpensive Way to Lower One's Risk of Heart Disease. Don't worry, we're not asking you to drink two glasses of red wine every day over a leisurely 4-hour lunch, as the French do (although it doesn't sound like punishment!). Even if you don't drink red wine, you can gain the same benefits by drinking red grape juice or taking a nutritional supplement that contains red wine polyphenols. Because red grape juice also is very high in sugar and calories, red wine extract is the low-calorie choice to obtain the amazing and broad-spectrum benefits of the magical red grape.

What role does nitric oxide play in promoting proper blood flow throughout the body? Plenty! Inside your body nitric oxide is produced by endothelial cells that line your blood vessels, and acts as a messenger molecule by telling the blood vessels when to relax and expand. When adequate nitric oxide is produced, it causes an " endothelial relaxing factor, " which is needed by the arterial system to expand and contract with each heartbeat. This helps regulate blood flow and pressure, so that oxygen-carrying blood is delivered to your tissues and organs.9.10 Nitric oxide causes all of the capillaries and little blood vessels to relax and go to their biggest open position. This allows unrestricted blood flow. But if nitric oxide production is impaired, the result is endothelial dysfunction, or the inability of the arterial system to expand and contract. This is a major cause of hypertension and has also been linked to high cholesterol, atherosclerosis, diabetes, blood clots, infection, and heart failure. 11 Endothelial cells both produce and respond to nitric oxide in a self-regulating way, something like this. Say you have a garden hose with a sprayer attached to it. When you squeeze the handle, pressure is released within the hose as the water flows. As you release the sprayer, pressure builds and the hose swells. Nitric oxide acts in a similar way. Think of it as the handle on the garden hose, or as a messenger regulating the pressure and flow of the blood inside the capillaries and blood vessels. When nitric oxide is produced inside the endothelium, it rapidly spreads through the cell membranes to the underlying muscle cells. Their contraction is turned off by nitric oxide, resulting in a dilation of the arteries. This is how nitric oxide controls the blood pressure and blood flow. Nitric oxide also helps prevent blood clots because it prevents blood aggregation or platelets from being excessively sticky and ultimately resulting in the formation of blood clots.
