Coffee is a superfood that has shown great promise for brain health. Research published in 2016 in Alzheimer Disease & Associated Disorders examined the data of nearly 600 people aged 90 and over (who did not have dementia at the commencement of the study) to query how lifestyle factors influence the health of this segment of the population.

The researchers found that caffeine consumption was one of the few lifestyle factors that may be related to a reduced risk of incident dementia. Participants who consumed 200 milligrams or more per day of caffeine had a 34% lower risk compared with those who consumed less than 50 milligrams per day.
