Of the total participants, 47 percent reported having had COVID-19 infection. The omnivorous group had a significantly higher incidence of infection (52 percent vs. 40 percent) and were more likely to experience moderate to severe symptoms (18 percent vs. 11 percent).

After adjusting for influential factors such as weight, pre-existing medical conditions, and physical activity levels, there was no overall difference in symptom severity between the groups. However, those following predominantly plant-based or vegetarian diets were 39-percent less likely to become infected than their omnivorous counterparts.

The researchers suggest that plant-based diets may contribute to a boosted immune system and better defense against viral infections due to their richness in antioxidants, phytosterols, and polyphenols.
