My Patients Ask — Is it true that my diet can reduce my risk of COVID?

Recent research has revealed that your diet may indeed be tied to a lower risk of severe COVID — which may be very important information for those choosing not to take the COVID vaccine.

The study authors say that several studies have hypothesized that dietary habits may play an important role in COVID infection, the severity of symptoms, and the duration of illness. However, no previous studies have investigated the association between particular dietary patterns and COVID.

The study, which was in BMJ Nutrition, Prevention & Health, surveyed frontline physicians and nurses from six countries (France, Germany, Italy, Spain, UK, USA) with substantial exposure to COVID.

The survey indicated that those who ate a plant-based (vegetarian or vegan) or pescatarian diet had a 73 percent and 59 percent decreased risk of suffering from moderate-to-severe COVID-19, respectively, compared with those who did not follow the diets.

This is not the same level of protection that you can get from a COVID vaccine, but it’s certainly nothing to sneeze at. In fact, the researchers concluded, “These dietary patterns may be considered for protection against severe COVID.”

The findings, based on data from 2,884 nurses and physicians, indicated that the high amounts of vitamins A, C, D, and E, as well as omega 3-fatty acids, in the plant-based and pescatarian diets may have offered protection from infection, the researchers said.

Furthermore, as I’ve told you in the past, these diets are associated with improved immune health, brain health, and heart health. What’s not to like about that?


This blog was accurate as of the day of posting. However, as the COVID-19 pandemic rapidly evolves and the scientific community’s understanding of the novel coronavirus and the COVID vaccine develops, the information above may have changed since it was last updated.
