Research has shown that coffee, when consumed in moderation, can have numerous health benefits, particularly for the brain. A recent study conducted in Hamburg, Germany, examined the brains of over 2,000 people aged 45 to 74 and found that those who regularly drank three to four cups of coffee a day had the strongest brain structure.
The study compared four groups of people who reported drinking coffee regularly: less than one cup a day, one to two cups a day, three to four cups a day, and five to six cups a day. The results showed that those who drank three to four cups of coffee had the best preserved cortical thickness, which is associated with higher intelligence.
However, the study design had its limitations. The authors noted that the group was relatively small and homogeneous, and that those who drank more coffee were healthier and more educated at baseline. They also pointed out that more research is needed to determine whether decaffeinated coffee has similar effects.
Despite these limitations, these initial findings add to the growing body of evidence supporting the idea that coffee is good for the brain and overall health. Coffee has been shown to slow cognitive decline and potentially reduce the risks of Parkinson’s and Alzheimer’s disease. Additionally, a 2017 meta-analysis found that coffee reduces the incidence of cardiovascular and other diseases as well as neurological metabolic liver conditions. Some studies suggest that three to four cups may be the optimal amount for maximum benefit.
While drinking your favorite beverage can improve brain structure and function, it’s important to note that caffeine can cause nervousness or heart palpitations in some people. To support overall brain health on a daily basis, it’s recommended to prioritize sleep
