Plant-based and/or fish (pescatarian) diets may help lower the odds of developing moderate to severe COVID-19 infection, suggest the findings of a six-country study, published in the online journal BMJ Nutrition Prevention & Health.
They were associated with 73% and 59% lower odds, respectively, of severe disease, the findings indicate.
Several studies have suggested that diet might have an important role in symptom severity and illness duration of COVID-19 infection. But, as yet, there’s little evidence to confirm or refute this theory.
To explore this further, the researchers drew on the survey responses of 2884 frontline doctors and nurses with extensive exposure to SARS-CO-v2, the virus responsible for COVID-19 infection, working in France, Germany, Italy, Spain, the UK, and the US.
The participants were all part of a global network of healthcare professionals registered with the Survey Healthcare Globus network for healthcare market research. The researchers used this network to identify clinicians at high risk of COVID-19 infection as a result of their jobs.
