Can Red Wine Save From Covid19? What do experts say on the new study?

Many of these studies have their limitations in the way they are conducted, which is why we often see one food being cited as good for us one day and refuted by another study the next. . This contradiction in the study’s findings is a source of continuing frustration in the field of nutrition science.

Let’s explore some of the reasons why these studies can be misleading.

What were the findings?

Several conclusions emerged in this study. From the media perspective, there were many interesting things in this research such as:-

  • Drinking one to four glasses of red wine a week reduced the risk of getting Covid by about 10%.
  • Drinking five or more glasses of red wine a week reduced risk by 17%.
  • Although drinking white wine and champagne also appeared to be protective, they had a lesser effect than red wine.
  • In contrast, drinking beer was found to increase the risk of getting covid by 7–28%.

It was difficult to identify clear patterns with some other findings. For example, while drinking alcohol increases the risk of getting covid, drinking fortified wine only in small doses appears to be protective.

Similarly, drinking alcohol more frequently was associated with a lower risk of getting Covid, drinking more than the UK guidelines for alcohol consumption was associated with an increased risk of exposure to Covid.

Let’s delve deeper into red wine findings to explore some of the reasons why the results of these types of studies should be skeptical.

The first and most obvious reason to be cautious when interpreting this study is that correlation does not equal causation.

You hear this phrase all the time, but that’s because it’s so important to distinguish between two variables that are intertwined, and cause each other.

This analysis was accomplished with data gathered from a large and long-term study, a study in which you determine participants and guide them over time to collect information about their behavior and health. track.

Although the study had an impressive number of participants from the UK Biobank cohort, the analysis only included looking for an association between alcohol consumption patterns and diagnosis.

As this was an observational study where data was collected and analyzed from people leading their normal lives, one can say with confidence that drinking red wine is associated with a lower risk of diagnosis. associated with possibility. But no one can say that the real reason for the low risk of getting Covid in the research group was drinking red wine.

It is entirely possible that this association reflects other differences between those who drink red wine and those with Covid infections. This phenomenon is called “confounding”, and it is very difficult to completely remove the effects of confusion in observational studies to know exactly what is happening.

Although the researchers attempted to statistically adjust the results in this study to remove some apparent contradictions – such as age, gender and education level – this type of adjustment is not accurate.

There is also no guarantee that there were no other sources of confusion in the study that were not considered.

The data on drinking is unreliable

The data collected regarding drinking patterns in this study has two major limitations.

The first is that collecting information about what people eat and drink is extremely unreliable.

And the bigger problem is that the extent of this misreporting varies greatly between people, making it very difficult to fix.

A second major limitation was that the researchers collected data on drinking patterns at the beginning of this longitudinal study and used the same data throughout their analysis over the years, assuming that people’s drinking patterns were similar throughout the period. Were.

Clearly a person’s drinking patterns can change significantly over the years, so this can be a huge source of potential error.

So, when it comes to drinking alcohol, always remember that you should not drink it keeping in mind any purported health benefits related to covid or any other disease. You should drink in moderation if you enjoy it, and be clear why you are drinking.
