Do you drink two to three cups of coffee a day? Scientists have discovered a link to dementia risk

Recent research indicates that consuming two to three cups of caffeinated coffee daily may reduce the risk of dementia, even among genetically predisposed individuals. A study involving over 131,000 adults showed that those who abstained from coffee had a higher incidence of dementia. The findings suggest that lifestyle factors significantly influence dementia risk. The optimal coffee consumption was linked to an 18% lower risk of dementia compared to infrequent drinkers. Similar benefits were observed with tea, while decaffeinated coffee did not show the same protective effects. The study highlights caffeine's potential role in neuronal signaling and amyloid beta accumulation reduction, which is associated with Alzheimer's disease.
