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.”

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 substances in red wine also tone up 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.

Must Drink: 6 Health Benefits of Red Wine

Pouring red wine from bottle into glass with wooden wine casks on background

Red wine is not only deep, aromatic and tasty. This is a real medicine – it is a glass of red that doctors advise drinking daily. Modern research confirms: this is a cure for many ailments. And no alcoholism!

A snow-white smile

Red wine sometimes stains the teeth, but it turns out that this is only good for them. This layer protects the enamel from bacteria and alkali from other products that we consume with wine.

The wine itself acts as an antibacterial drug and contributes to the prevention of caries. And for dessert: a glass of red wine relieves inflammation of the gums and even a sore throat (it’s not for nothing that the best remedy for a sore throat is mulled wine).

Slim figure

French scientists back in 2011 published in the scientific journal FASEB the results of a study that confirms that restevarol in red wine breaks down cholesterol: the same animal fat that is deposited in unnecessary places and clogs the walls of blood vessels.

Wine tones muscles, relieves muscle pain after exercise and is indicated for office workers who move little to lose a few pounds due to the metabolism accelerated by red wine.

Total cleansing

The same Restevarol is able to remove free radicals from the body, which lead to cancer. At the same time, as a biological additive, restevarol was recognized as ineffective and recommended only in red wine – here it did not disappoint the researchers and showed its healing properties in the best possible way.

Internal affairs

In addition, red wine has a positive effect on the internal organs. Vessels – cleanses. Stomach – starts like a motor. Nerves – soothes. Pressure – normalizes. Muscle pain – relieves.

And the best part: it promotes the breakdown of kidney stones. Excellent, tasty and pleasant alternative to surgery.

Love to all!

According to a 2009 Koch Institute study, drinking red wine eliminated libido problems in 30% of men and 48% of women.

If you don’t have problems, and we hope so, red wine will always help you relax, loosen up, “disperse the blood”. Therefore, a bottle of good red is the best choice for dinner, which is planned to be smoothly and pleasantly translated into breakfast.
