A vegan diet reduces severe COVID-19 symptoms by 73 percent.

Though a study has shown this, a correlation has not yet been properly established.

Although several studies have shown that plant-based diets can help with people's weight and energy metabolism, no studies have directly linked the effect of nutritional habits and dietary preferences on the severity or duration of COVID-19.

A recent study published in BMJ Nutrition Prevention and Health noted that those who followed a plant-based or pescatarian diet had a smaller chance of moderate-to-severe COVID-19 when compared to the participants who did not follow a plant-based or pescatarian diet. To be specific, the study said that vegans and pescatarians had 73 percent and 59 percent lower odds respectively of moderate-to-severe COVID-19.

The self-reported information was obtained from healthcare workers from six countries who had been substantially exposed to COVID-19 patients.

However, this study did not establish the link between self-reported diets and COVID-19 severity or duration. The study has only been externally reviewed by two individuals and is yet to be fully peer-reviewed.

Another study published in the Journal of Public Health indicated that patients with lower consumption of poultry and fruit in the usual diet had a more severe form of the disease. It suggested that consuming more fruits and poultry, and drinking less tea, could reduce the severity of the disease.

The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation. For reliable advice on COVID-19, including symptoms, prevention, and available treatment, please refer to the World Health Organization or your national healthcare authority.
