A new study from researchers in Ireland indicates that drinking coffee, whether caffeinated or decaffeinated, can improve gut health and mood. The research found that regular coffee drinkers exhibited increased levels of beneficial gut bacteria, such as Firmicutes, Eggerthella, and Cryptobacterium curtum, which support metabolism and digestion.
Study Details
Participants in the two-year study, led by Professor Cryan of the University of Cork, reported reduced stress, depression, and impulsivity after reintroducing coffee, irrespective of its caffeine content. Significantly, only decaffeinated coffee drinkers showed improvements in learning and memory, suggesting that non-caffeine components of the beverage are responsible for this particular benefit.
Broader Health Implications
These findings add to existing research that highlights coffee's health advantages, including a reduced risk of dementia, slower biological ageing, and lower mortality rates. The study underscores that both regular and decaffeinated coffee can contribute positively to overall well-being.
