Can coffee drinking prevent COVID infection?

Coffee has undergone a dramatic rehabilitation since it was designated as a “possible” bladder carcinogen by the International Agency for Research on Cancer (IARC) in 1991.

In the past twenty years, large, prospective epidemiologic studies have pointed to an impressive but still only suggestive reduction in the risk of developing numerous types of cancer associated with drinking coffee. After having a brief spell as something to be shunned, coffee appears to have potential health benefits. 

Now, two recent papers suggest that coffee may provide protection against COVID-19 infection. It’s creating headlines across the internet. How solid is the evidence?

 

Researchers in Taiwan reviewed biochemical evidence that compounds present in coffee inhibit infection with SARS-CoV-2. They also reported the results of a small study indicating that drinking 1-2 cups of coffee per day “is sufficient to inhibit infection of multiple variants of SARS-CoV-2 entry, suggesting coffee could be a dietary strategy to prevent SARS-CoV-2 infection.”

The Taiwan paper published this year cites a paper by researchers at Northwestern University, which used data from the UK Biobank’s prospective epidemiologic study of roughly half a million participants (aged 37 to 73) to examine the association of dietary intake with the risk of COVID infection.   

The authors reasoned that factors including coffee, tea, red meat, fish, vegetables, and fruits, might influence immune function and, thereby, affect the risk of COVID infection and its sequelae. :snip:

"Can coffee drinking prevent COVID infection?"

 

Didn't work here. We are close to 3 weeks now, but much better the last few days. We had no Christmas, didn't want to infect anyone else.  Sad , sad thing is that coffee tastes terrible ( dinking it anyway for spite) and apparently will for quite a while.
