Coffee, both caffeinated and de-caffeinated, modifies our brain functions by triggering changes to the bacteria in our gastrointestinal system. Microbiome researchers at Ireland’s University College Cork intensely analyzed 62 coffee and non-coffee drinkers looking at their cognition, gastrointestinal, and general physical functions. Their study appears in the journal Nature Communications.

Coffee drinking significantly modifies gut bacteria and the biochemical reactions they influence. In so doing, caffeinated coffee lowers stress and anxiety levels, improves attention and alertness, but also increases impulsivity. On the other hand, decaf coffee improves memory and learning.

The bottom line: a cup of joe turns out to be a complex elixir that impacts your gut and, by so doing, your mental and emotional functioning in so many ways.
