New research conducted in Germany has found that drinking three to four cups of coffee a day may be the magic number for preserving critical brain structures, helping to improve cognitive abilities and overall brain function. The study, which was conducted on a relatively small and homogeneous group, found that those who drank three to four cups of coffee a day had the strongest brain structure when looking at several factors including preserved cortical thickness, which is generally associated with higher intelligence.
Coffee, in the right quantities, is proven to be good for the brain and overall health. It can help us live longer, reduce inflammation and reduce the risk of diabetes. A 2017 meta-analysis of the health effects of coffee found that coffee reduces the incidence of cardiovascular and other diseases, as well as neurological, metabolic and liver conditions. Although not all of these studies looked at the exact number of cups, some of them suggest a threshold of three to four cups for optimal benefit.
However, it’s important to note that more research is needed to determine whether decaffeinated coffee has similar effects. Additionally, potential confounding factors such as healthier and more educated participants cannot be ruled out in this study design. Nevertheless, these initial findings add to the growing body of evidence supporting the idea that coffee is good for our brains and overall health.
To support brain health on a daily basis, it’s recommended not to consume caffeine if you experience nervousness, anxiety or heart palpitations. Other ways include prioritizing sleep
