Fibre in diet linked to flu protection

It has long been known that a diet rich in fibre improves intestinal health and reduces inflammation in the gut. Now, a Monash University study shows that fibre can protect against the flu virus.

Professor Benjamin Marsland from the Department of Immunology and Pathology, Central Clinical School, together with Swiss colleagues, showed in mice that fibre fermented in the gut by bacteria countered influenza A, one of the most common viral diseases worldwide.

The findings, published today in Immunity, suggest that fermented fibre and byproducts of this process called short-chain fatty acids (SCFAs) could be investigated further for potential use in preventing and treating viral infections including the flu, and possibly as a supplement to improve the efficacy of the flu vaccine.

Not all fibres are created equally

Prebiotic fibre in legumes, garlic and onion may be better 
for your gut than some fruits and vegetables.

Diets including fibres found in legumes, garlic and onion may hold the key to a healthier gut according to a study conducted by Monash PhD student, Daniel So.

Through a detailed analysis and review of 64 papers, the study found that the consumption of prebiotic fibres would nourish and increase good bacteria in the gut resulting in a more harmonious digestive system.
