New research by scientists at the University of York suggests that there is a potential link between eating Marmite and activity in the brain.
The study found that participants consuming a teaspoon of Marmite every day for a month, compared to a control group who consumed peanut butter, showed a substantial reduction of around 30 per cent in their brain’s response to visual stimuli, measured by recording electrical activity using electroencephalography (EEG).
Commenting on the research Dr James Pickett, Head of Research at Alzheimer's Society said: "Evidence shows that our diet plays an important role in the way our brain functions. This research only looked at how men in their 20s responded to visual stimuli rather than testing their thinking or memory, so there’s no way to say from this study whether eating Marmite can affect your dementia risk. But the study does give us a deeper understanding of how certain aspects of diet could affect the function of nerve cells in the brain.
"Along with eating a healthy diet, the best ways to reduce your risk of dementia are to exercise regularly, avoid smoking and keep your blood pressure in check."
