Several studies suggest that diet could play an important role in the development – whether positive or negative – of Covid-19. But which eating habits would help keep the virus at bay?
Researchers from the University of Sao Paulo (Brazil) therefore set out to evaluate the effects of different diets on the frequency, severity and duration of infections in 702 volunteers recruited between March and July 2022.
Divided into two groups, on the one hand followers of a predominantly plant-based diet and on the other hand omnivores, the participants reported several of their medical criteria, including their vaccination status against Covid-19.
First observation: omnivores reported more health problems (more cases of being overweight or obese, etc.) and lower physical activity.
As for Covid-19, 330 people reported being infected with it during follow-up. 224 showed mild symptoms and 106 were affected by a moderate to severe form. Omnivores were more contaminated. They were also more likely to have a severe course. “Those who ate a predominantly plant-based (little or no dairy and meat) or vegetarian/vegan diet were 39% less likely to become infected than omnivores,” the authors say. “A plant-based diet may provide more nutrients that strengthen the immune system and help fight viral infections. »
