U.S. researchers at Northwestern University in Illinois have found that regular coffee consumption can reduce the likelihood of becoming infected with COVID-19. The results of the study were published in the journal Nutrients.
Those who drink one or more cups of coffee a day have about a 10% lower risk of coronavirus infection than people who do not consume this beverage. The risk of developing pneumonia is also lower among older coffee lovers.
Scientists draw similar conclusions regarding the consumption of vegetables. For the purpose of their research, they use data from the British Biobank. They examined the links between dietary behavior observed in 2006-2010 and the prevalence of COVID-19 in March-December 2020, before vaccines were available.
Researchers are focusing on dietary factors and reports of coffee, tea, vegetables, fruits, oily fish, processed and red meat. Among the 37,988 participants tested for COVID-19 and included in the study, 17% tested positive. The researchers found that one or more cups of coffee a day was associated with about a 10% lower risk of contracting COVID-19 than drinking less than one cup a day.
Consumption of cooked or raw vegetables, with the exception of potatoes, is also associated with a lower risk of infection with COVID-19. At the same time, the presence of processed meat, even in small quantities, increases the risk of infection with COVID-19. Breastfeeding also reduces the likelihood of about 10% compared to when there is no breastfeeding.
The exact mechanisms that link these dietary factors to COVID-19 are unknown.
It is still difficult for scientists to find an answer as to why some people become infected and have a severe illness, while others do not become infected or show no serious signs of illness. We all know that nutrition affects our health. Researchers point to another good reason to stick to a healthier diet. However, do not underestimate other remedies, because 10 is a relatively small percentage and keep yourself healthy.
