Drinking more than 1 cup of coffee daily may reduce the risk of Alzheimer’s Disease, according to a 2021 long term Australian study. This study went for over 10 years and the adults in the study were an average age of almost 70 when it started, and of normal cognitive ability. Over the next 10 years they were tracked and those with higher coffee consumption had a lower chance of transitioning to Alzheimer’s status in that time.
