Experts are urging caution over a new report - suggesting drinking coffee can reduce the risk of Alzheimer's disease.
It claims having between 3 and 5 cups a day may bring down the chance of developing the condition by up to a fifth.
However, charity Alzheimer's Research UK says there's 'not enough evidence' at the moment to 'draw firm conclusions' about the effect coffee has on dementia.
The report released just today from the Institute for Scientific Information on coffee highlights the role nutrition can play in preserving cognitive function, according to the Telegraph.
Dr Arfran Ikram, an assistant professor in neuroepidemiology at Erasmus Medical Centre Rotterdam said: "The majority of human epidemiological studies suggest that regular coffee consumption over a lifetime is associated with a reduced risk of developing Alzheimer's Disease, with an optimum protective effect occurring with three to five cups of coffee per day."
Earlier this month, the Irish Coffee Council has released research which shows that drinking three or four cups a day can reduce the risk of type two diabetes by up to 25%.
