Eating fibre can improve health, lengthen lifespans, and even protect our brains. Yet many of us are still coming up short on this “essential nutrient”.

A diet high in wholegrains, fruits, pulses, nuts and seeds – all of which are full of fibre – can have huge benefits for both our bodies and our brains.

Emerging research shows fibre supercharges the microbiome and influences the gut-brain axis, which is the communication channel that runs between the gut and the brain; slowing down symptoms of cognitive decline.

Increasing fibre intake is one of the most impactful dietary changes for cognitive health, says Karen Scott, professor of gut microbiology at the Rowett Institute, University of Aberdeen. Alternatively, a fibre deficit has been found to be a leading dietary risk factor for ill health.
