Coffee, Alzheimer’s and dementia
Having a coffee is a regular occurrence for many of us, be it to break through the morning fog, for that perfect cup at a favourite café, or to help you through the late night chores.
I used to drink around four mugs of percolated coffee a day. When it occurred to me that this was probably a bit excessive. I cut down and became extremely grumpy, had nasty headaches, and lived with a hazy feeling for around week. Interpreting this as some type of withdrawal – surely coffee wasn’t good for me?
Interestingly, a study suggests drinking a number of cups of coffee a day could actually be a great benefit.
Eskelinen and colleagues (2009) used a random selection of survivors from two large population-based cohorts from studies in the 1970’s and 1980’s. There were 1409 individuals aged from 65 to 79 years old, who completed the follow-up survey in 1998. Results showed that people that drank coffee at midlife had a lower risk of dementia and Alzheimer’s disease later in life, than those who did not drink coffee or only a little. People who drank 3-5 cups per day were found to have the lowest risk (65% decrease).
So maybe that extra cup of coffee is not so bad after all…
