According to the Yale University study, mice fed a ketogenic ‘keto’ diet were better able to combat the flu virus than mice fed food high in carbohydrates.

The researchers found that the ketogenic diet triggered the release of gamma delta T cells in the lungs. This enhances mucus production from airway cells to help effectively trap the virus.
