Coffee's impact on gut and brain functions
A recent study shows that coffee consumption is associated with changes in the gut microbiome and effects on mood, memory, and attention, regardless of whether the coffee contains caffeine or is decaffeinated. The study recorded variations in the levels of certain bacteria and metabolic compounds after stopping coffee intake and then reintroducing it. Notably, decaffeinated coffee was found to improve cognitive functions such as learning and memory, while caffeine was observed to reduce anxiety and enhance alertness. The research suggests that other components in coffee, beyond caffeine, may influence brain functions through interactions with gut microbes. However, it does not establish a direct causal relationship and encourages further research to better understand the connection between coffee, gut health, and brain function.
