Reflection on the Effects of Chronic Coffee Consumption on Brain Function and PerformanceAs a dedicated coffee drinker, I was intrigued to learn about the effects of chronic coffee consumption on brain function and performance. The article by Magalhães et al. (2021) showed the impact of habitual coffee drinking on human brain networks. The study divided subjects into two groups, habitual coffee drinkers (CD) and non-coffee drinkers (NCD), and assessed their brain functional connectivity using resting-state functional magnetic resonance imaging (fMRI). The researchers also tested for stress, anxiety, and depression levels for both groups.A major takeaway from the article was the finding that the CD group exhibited decreased functional connectivity in the somatosensory and limbic networks during resting state (Magalhães et al., 2021). Additionally, the CD group displayed decreased functional connectivity in brain regions associated with somatosensory, motor, and emotional processing. Interestingly, these differences were dependent on the frequency of caffeine consumption and were reproduced after NCD drank coffee. Another significant finding was the impact of caffeine consumption on psychological factors.

However, I now understand that chronic coffee consumption has a more complex influence on brain functional connectivity, with implications for emotionality, alertness, and readiness to action (Magalhães et al., 2021). So, based on the findings of the study, I plan to make a few nutritional lifestyle changes to promote better brain health and performance. I am going to be reducing my coffee consumption, especially considering the potential for increased anxiety. Additionally, I might try to incorporate alternative sources of energy, such as green tea, which contains lower levels of caffeine and other beneficial compounds, like antioxidants......
