“… participants who reported following ‘plant-based diets’ and ‘plant-based diets or pescatarian diets’ had 73% lower odds of moderate-to-severe COVID-19 severity, respectively, compared with participants who did not follow these diets. Compared with participants who reported following ‘plant-based diets’, those who reported following ‘low carbohydrate, high protein diets’ had greater odds of moderate-to-severe COVID-19. No association was observed between self-reported diets and COVID-19 infection or duration.”
[Did you get that? Keto/Adkins type low-carb high-protein plant-based diets not so good here.]
“Conclusion In six countries, plant-based diets or pescatarian diets were associated with lower odds of moderate-to-severe COVID-19. These dietary patterns may be considered for protection against severe COVID-19.”
