Printed final week within the Journal of Alzheimer’s Illness, the examine seemed on the mind’s of 575 deceased sufferers with a mean age of 91 years. None had Alzheimer’s.
For greater than 20 years earlier than their deaths every had crammed in a survey yearly on their eating regimen permitting researchers to maintain observe.
Additionally they had their cognitive means examined yearly.
Outcomes from autopsy confirmed that among the many group that ate probably the most strawberries, the bottom focus of tau proteins was noticed.
The examine authors additionally mentioned they discovered no affiliation between tau protein ranges and those that had the APOE-4 gene, which is assumed to lift the chance of the illness.
Explaining the outcomes Dr Julie Schneider, the neuropathologist who led the paper, mentioned: ‘We suspect the anti-inflammatory properties of pelargonidin could decreaes general neuroinflammation, which can scale back cytokine manufacturing.’
Cytokines are proteins produced by cells which may set off an inflammatory response.
Irritation within the mind could also be brought on by many components together with an absence of sleep, infections and excessive stress. These are additionally threat components for creating Alzheimer’s illness.
Dr Puja Agarwal, a dietary epidemiologist who was additionally concerned within the analysis, mentioned it was a ‘easy change’ that anybody might make to their eating regimen.
However he additionally warned the examine was observational, which means it was not clear whether or not the strawberries decreased the chance.
‘Additional analysis is required to grasp the function of diet in Alzheimer’s illness,’ he mentioned, ‘however this examine offers us hope on how particular dietary elements resembling berries could assist mind well being’.
Alzheimer’s illness is a debilitating situation affecting greater than 6.5million Individuals. By 2050, this determine is predicted to greater than double.

However quite a lot of research have investigated sure meals — together with blueberries, strawberries and leafy greens — as presumably providing safety towards the illness.
These meals had been chosen for his or her anti-inflammatory properties, thought to assist scale back the chance of harmful proteins build up.
