Drinking red wine for heart health? Read this before you toast

For years, studies have shown a relationship between drinking a moderate amount of red wine and good heart health, but experts say it’s important to understand what that means before you prescribe yourself a glass or two a day.

No research has established a cause-and-effect link between drinking alcohol and better heart health. Rather, studies have found an association between wine and such benefits as a lower risk of dying from heart disease.

It’s unclear whether red wine is directly associated with this benefit or whether other factors are at play, said Dr. Robert Kloner, chief science officer and director of cardiovascular research at Huntington Medical Research Institutes and a professor of medicine at the University of Southern California.

“It might be that wine drinkers are more likely to have a healthier lifestyle and a healthier diet such as the Mediterranean diet, which is known to be cardioprotective,” he said.

But you may not even have to drink red wine to get the benefit, Kloner said. Moderate amounts of beer and spirits also have been linked to a lower risk of heart disease.

It’s a common assumption that red wine may be good for the heart because it contains antioxidants such as resveratrol, which is primarily found in the skin of grapes but also peanuts and blueberries. Some studies suggest resveratrol can reduce cholesterol and lower blood pressure.

“There’s a debate about whether resveratrol is really cardioprotective or not,” Kloner said. “In addition, there is debate about the amount of resveratrol you would need to ingest to get a protective effect. To get the equivalent of the amount of resveratrol that has been reported to be protective would probably mean ingesting an excess of wine.”

Federal guidelines and the American Heart Association recommend that if you do drink alcohol, to do so in moderation. That means no more than one to two drinks per day for men and one drink per day for women. (According to the AHA, one drink is 12 ounces of beer, 4 ounces of wine, 1.5 ounces of 80-proof spirits or 1 ounce of 100-proof spirits.)

Studies have found that moderate alcohol consumption may have some health benefits, including raising “good” HDL cholesterol levels and lowering the risk of diabetes. However, excessive drinking can lead to a host of health problems, including liver damage, obesity, some types of cancer and stroke, not to mention its negative effect on the heart.

“Alcohol in excess is really bad for the heart,” Kloner said. “It can cause high blood pressure and promote arrhythmias. It can cause cardiomyopathy where the alcohol is actually toxic to the heart muscle cells, and that can lead to heart failure.”

Proving moderate alcohol use causes better heart health would be tricky, Kloner said. Ideally, it would require a large prospective study that not only randomly assigns people to a no-drinking group versus a moderate-drinking group, but that also compares different types of alcohol – red wine, white wine, beer, spirits – to determine if one really is better.

“And then you’d have to control for various factors – age, gender, cardiovascular risk, their diet. You’d have to follow them for many years,” he said, noting the added ethical dilemma of taking people who are not drinkers and telling them to become drinkers.

For now, the message certainly isn’t to go out and start drinking, Kloner said. “But if you do drink, drinking in moderation is the way to go.”

Is there any benefit from wine – the benefits of drinking wine

Scientists and researchers have been talking about the health benefits of drinking wine for many years. The key to the health benefits of wine is, of course, moderation. Discover some of the many health benefits of wine.

Wine raises good cholesterol

Numerous studies show that wine, red or white, raises HDL cholesterol. HDL cholesterol is often referred to as “good” cholesterol. This type of cholesterol actually helps reduce the fat on the walls of your arteries by delivering it to your liver. The liver then processes these fats into waste and your body eliminates them.

Fighting free radicals

Free radicals are basically groups of atoms that attack healthy cells causing damage to cells. Antioxidants help counter the damage caused by free radicals. The flavanoids and resveratrol in wine act as antioxidants to fight free radical damage to cells.

Relieves anxiety

Wine acts as a mild natural sedative. One glass of wine of 150-200 grams helps relieve anxiety and tension. When stressed, the heart pumps blood faster and works harder, putting people with high levels of stress at increased risk of heart attacks and cardiovascular disease. The anti-anxiety effect of wine helps slow heart palpitations to a more normal, healthy level and lowers blood pressure. Scientists have proven that the antioxidants in wine slow down the development of arterial plaque. In this way, wine helps prevent arthrosis, thereby helping to slow down or prevent heart disease.

Ulcer Prevention

A 2003 study by the American Journal of Gastroenterology found that regular wine drinkers reduced their risk of developing ulcers by helping the body rid itself of the specific bacteria known to cause these ulcers. However, the study noted that wine consumption should be moderate, and excessive consumption leads to an increased risk of developing peptic ulcers.

Heart health

The heart experiences the many health benefits of wine. Along with the cholesterol and anti-anxiety benefits mentioned above, drinking wine moderately and regularly helps prevent a heart condition known as cardiac fibrosis. Cystic fibrosis of the heart occurs when proteins build up in the heart valves, causing them to thicken. With this thickening, the heart beats much less efficiently. Wine helps prevent the formation of these proteins inside the heart valves.

Wine as an anti-inflammatory agent

Regular and moderate wine consumption has anti-inflammatory properties.

Enhanced Lung Function

Another of the health benefits of wine is that flavonoids and other antioxidants have been shown to increase lung function, making them more efficient.

Protecting blood vessels

Polyphenolic compounds found in wine, known as procyanidins, help protect blood vessels from damage. They also work to protect the endothelium. The endothelium is the protective tissue around the heart and blood vessels.

Brain function

A 2006 preliminary study by the Federation of American Societies for Experimental Biology found that regular and moderate wine consumption can help slow memory loss and also prevent brain cell death. This reduces the risk of developing diseases associated with dementia and dementia, such as Alzheimer’s disease.

5 healthy reasons to agree to a glass of wine are named: against cholesterol

Disputes about the influence of a moderate amount of alcohol on the body, especially for women, have not subsided for a long time. Supporters of a healthy lifestyle are categorically against even small amounts of such “doping”. Some researchers, too, believing that even in small doses, alcohol can lead to irreversible changes in the body. On the other hand, opponents note that wine is part of the famous Mediterranean diet, which is considered one of the healthiest. Finally, since ancient times, the inhabitants of the Caucasus and Italy cannot imagine their life without wine, and at the same time they are distinguished by enviable longevity. Nutritionists agree that the truth, as always, is somewhere in between.

If we talk about dry wine and very limited quantities, there are still benefits from drinking it, concludes Harper’s Bazaar. The publication emphasizes that in this case we mean a daily portion equal to one glass. Also, we are talking about dry wine, since dessert wines have too much sugar.

The first positive thing from a glass of dry red wine at a meal is getting polyphenols, which have a beneficial effect on the heart vessels. The resveratrol contained in the skin of grapes, according to a number of studies, has a number of useful functions: it reduces “bad” cholesterol, protects blood vessels, reduces blood clots and has an anti-inflammatory effect, and also helps maintain bone strength. It is also believed that this substance helps to slightly reduce the risk of developing certain types of cancer, but these assumptions have not been confirmed.

Substances in red wine have an antioxidant effect, that is, they help slow down the aging process. Grapes contain many polyphenols and tannins, the concentration of which increases during fermentation. Antioxidants protect cells from damage by free radicals, therefore, slow down age-related changes in the cells of organs and skin. Red wine is also full of phytoestrogens, which stimulate the body’s production of collagen and hyaluronic acid.

The active ingredients in red wine also tone the nervous system by improving the blood supply to the brain. According to the observations of a number of researchers, the cumulative effect of red wine becomes the prevention of age-related memory degeneration and even Alzheimer’s disease.

The already mentioned polyphenols protect the body from chronic diseases by fighting inflammation. Also, the components of wine can increase the body’s susceptibility to insulin, which helps in the prevention of diabetes.

The fifth and very important positive effect of red wine is a good mood. This is not about the feeling of intoxication, but about the high content of fruit acids and tannins in this drink, which scientists associate with an increase in the general emotional background and even the prevention of depression. But there is an important note: such an “antidepressant” works only if no more than 1 glass is consumed per day. With an excess of alcohol on the face, the opposite effect is depression of the nervous system and health problems, in the presence of which the mood simply cannot be good.
