A study by scientists at Yale School of Medicine suggested that a ketogenic diet might provide a degree of protection from the flu.
Lead author Akiko Iwasaki found ketosis in mice boosted certain immune cells and the protection of protective mucus in the lungs.
The study noted: “The keto diet may represent a viable avenue toward preventing or alleviating influenza disease.”
However, Dr Grace says there’s a big difference between mice and humans and she’d be concerned about the large numbers of people jumping on the keto bandwagon just because of this.
Dr Farhat added: “This is a study on mice and although it shows promising results, unless we prove in humans, we can’t make any bold claims about the way the diet might affect us.”
