A recent study associated the consumption of wine with a protective effect against Covid-21 and reduce the risk of infection. However, scientists have reservations about these results.
The study conducted by Chinese scientists and published in Frontiers in Nutrition analyzed the medical records of more than 470,000 people in the UK Biobank database. Drinking habits and Covid history during the course of the pandemic were included.
According to the conclusion of the study, red wine, white wine and champagne have the potential to reduce the risk of COVID-19. The risk of contracting covid-19 was between a 10 and a 17 percent lower for people who drink red wine. The consumption of white wine and champagne can reduce the risk by up to 8%.
Those who consumed five or more glasses of red wine a week had up to a 17 % less likely to be at risk of becoming infected compared to non-drinkers.
In contrast, consumption of beer and spirits was found to increase the risk of infection compared to non-drinkers. The risk is 22 percent higher with five or more glasses per week.
The authors of the study point out that among the possible explanations for the findings are polyphenols, which are more present in red wine and have been associated with health benefits.
Researchers question whether wine can protect against coronavirus
The results of the study should be treated with tweezers. Excessive alcohol consumption was associated with an increased risk of COVID-10. Research has shown that long-term alcohol abuse and binge drinking are associated with immunosuppression.
The World Health Organization agrees that alcohol has a deleterious effect on the system immunological and does not stimulate immunity and resistance to the virus. “Alcohol consumption, especially excessive consumption, weakens the immune system and, therefore, reduces the ability to deal with infectious diseases,” says the WHO.
Researchers told Newsweek his skepticism about the protective effects of wine. “The idea that polyphenols in wine could reduce your risk of developing COVID by a staggering 17 percent is simply not credible,” said Colin Angus, a senior researcher in the Sheffield Alcohol Research Group at the University of Sheffield in the UK.
Another researcher pointed out to Newsweek the different exposure to which consumers are subjected . “The biggest risk is contact with the virus in the first place and I note that wine and fortified wine tend to be consumed in small groups or at home, while beer is generally consumed in more collective outdoor gatherings,” Ian said. Jones, professor of virology at the University of Reading.
How to consume polyphenols in wine in a healthier way
The consumption of a single glass of alcohol, including wine, can have negative effects on health, such as an increased risk of cancer, heart failure and fatty liver.
The Harvard School of Public Health publishes that dealcoholized wine preserves the content of polyphenols. Polyphenols are found in the skin of red and purple grapes. Red wine-specific polyphenols include resveratrol, quercetin, and epicatechins.
Polyphenols, including a specific type called flavonoids, in addition to grapes, are also found in other plant foods, such as blueberries, strawberries, apples, dark chocolate, and tea .
