Drinking Wine Protect Against Covid-19… Tannic acid, found in grapes and wine, can inhibit two critical enzymes in the coronavirus. However, alcohol does not protect against Sras-Cov-2, far from it.
Alcohol increases the number of ACE2 receptors which are the virus’s favorite target to infiltrate our cells. Its consumption also promotes inflammatory immune reactions which increase the risk of severe forms
ine decreases the antibody response and contributes to the development of diseases, such as obesity and diabetes, which increase the risk of having a severe form of infection.

Uncork a bottle of wine to avoid catching Covid-19? Unfortunately, it’s not that simple. Researchers at the Taiwan University of Medicine recently found that tannic acid, primarily located in grapes and wine, effectively inhibits the activity of two critical enzymes in the virus and prevents it from entering cell tissue. A discovery that has led some to take a shortcut a little too quickly, claiming that drinking wine protects against Covid-19.
Alcohol, dangerous for health.
Alcohol would have the opposite effect on the infection. This type of drink increases the number of ACE2 receptors, which are the virus’ favorite target to infiltrate our cells. Its consumption also promotes inflammatory immune reactions, which increase the risk of severe forms.
Also, wines, rums or other beers decrease the antibody response and contribute to the development of diseases, like obesity and diabetes, which increase the risk of developing a severe form of infection. More indirectly, excess alcohol alters behaviour and leads to less respect for barrier gestures, thus promoting the virus’s circulation and transmission.
Consuming alcohol is generally bad for your health.
A recent Canadian study, published June 15 in the Journal of Studies on Alcohol and Drugs, showed that even moderate alcohol consumption, following official recommendations, is dangerous. Researchers have found that more than 50% of cancers resulting from alcohol use occur in moderate drinkers and that 38% of all alcohol-related deaths are diagnosed in former drinkers or those who follow the guidelines. Weekly limits.
Tobaccoo questions about its effects
Researchers have also pointed to the potential protective effects of tobacco. A statistical link exists: a daily smoker would have between 2 and 10 times less risk of developing the disease (in current smokers and not in former smokers). This protection would be conferred by the presence of nicotinic receptors, similar to those of ACE2.
“Along with the harmful effect of tobacco on the respiratory tract, there is a specific paradoxical beneficial effect of nicotine that needs to be demonstrated,” concluded Professor Dautzenberg, pulmonologist, quoted by Pourquoi Doctor. This protective effect only attenuates the harmful effects observed for various viruses in former smokers. Still, in new smokers, without damage to the respiratory tract, smoking can very paradoxically enhance the course of covid-19.
The explanation for the above effect may be linked to either a lower penetration of viruses and a lower viral load or an impact on intracellular inflammation regulation under the impact of nicotine. “
