Coffee lovers, there’s reason to smile. As new study suggests that a cup of coffee a day may keep Covid-19 at bay.
A study conducted by researchers at Northwestern University in Chicago found that the “habitual consumption of one or more cups of coffee per day was associated with about a 10% decrease in risk of COVID-19” in comparison to consuming less than one cup. It says one or more cups of coffee per day can reduce the risk of catching COVID-19 by as much as 10 percent.
The findings stem from an analysis of nearly 40,000 participants in the U.K. Biobank (UKB). The team studied participants’ dietary habits in 2006-2010 and hypothesized the subsequent risk of coronavirus infection in 2020. Researchers specifically looked at participants’ consumption of coffee, tea, processed meat, red meat, fruit, vegetables and oily fish.
After adjusting for factors like race, age, sex and other factors like physical activity, BMI level and history of certain medical conditions, researchers found “habitual consumption of 1 or more cups of coffee per day was associated with about a 10% decrease in risk of COVID-19 compared to less than 1 cup/day.”
It says, “Coffee consumption favourably correlates with inflammatory biomarkers such as CRP, interleukin-6 (IL-6), and tumour necrosis factor I (TNF-I), which are also associated with Covid-19 severity and mortality.”
“The odds of COVID-19 positivity were 0.90, 0.90, and 0.92 when consuming 1 cup, 2–3 cups, and 4+ cups of coffee/day (vs. <1 cup/day), respectively,” the study reads.
The Northwestern University study further adds, “Coffee consumption has also been associated with lower risk of pneumonia in elderly. Taken together, an immunoprotective effect of coffee against Covid-19 is plausible and merits further investigation.”
Coffee contains antioxidant and anti-inflammatory properties, and “coffee consumption favorably correlates with inflammatory biomarkers” linked to “COVID-19 severity and mortality,” study authors wrote. “Taken together, an immunoprotective effect of coffee against COVID-19 is plausible and merits further investigation.”
“Although these findings warrant independent confirmation, adherence to certain dietary behaviors may be an additional tool to existing COVID-19 protection guidelines to limit the spread of this virus,” authors wrote.
The study found that foods with rich dietary sources of vitamins, folate, fiber, and several phytochemicals have anti-inflammatory, antibacterial, and antiviral properties and are thus immune-protective.
Processed meat consumption was said to be associated with higher risk of COVID-19 but red meat consumption presented no risk, researchers added.
Since the start of the coronavirus (COVID-19) public health crisis, NCA has received numerous questions about the impact the pandemic could have on coffee: Is it safe to drink? Can the coronavirus be transmitted or contracted via coffee or coffee packaging?
Coffee itself has never been considered a means of coronavirus transmission, and the risk of transmitting the virus via coffee packaging is extremely low, according to the CDC. In fact, regular coffee consumption has been proven to have surprising health benefits.
So no matter how you buy or brew your coffee, rest assured that your favorite beverage is completely safe to drink.
