A recent study has revealed eating a plant-based diet rich in whole foods can help protect against COVID-19.
And the staggering results indicate those on a ‘high quality’ healthy vegan diet were both less likely to catch the virus, and less likely to be hospitalized with it.
Whole food plant-based diet
Top researchers at Havard Medical School and King’s College London collated data from almost 600,000 individuals.
They asked respondents to fill in a detailed questionnaire about what they ate before and during the pandemic.
Then, researchers formed a ‘diet quality score’ from the overall nutritional value of what they typically eat.
Those with a high-quality score contained swathes of plant-based whole foods from fruits and vegetables to whole grains. Moreover, the best-rated diets contained fewer processed foods and refined carbohydrates.
The low-quality diets were consistent with a stronger risk of developing COVID-19. ‘This is the first time that diet has been shown to reduce the risk of developing the disease’, they claim.
The study was part of the ZOE COVID Symptom Study app, a non-profit scheme that aids COVID-19 research.
It proclaims itself as the largest ongoing study of the disease, working closely with King’s College London.
Another recent study also found the vegan diets can slash COVID-19 severity. It tracked healthcare workers across six countries who had been ‘substantially’ exposed to the virus.
Published in the BMJ, it similarly assessed the link between diets and the disease.
Those on a plant-based diet had 73 percent lower odds of developing moderate to severe COVID-19 severity.
However, those following ‘low carbohydrate, high protein diets’ had greater odds of moderate-to-severe COVID-19.
