Science Has Found Even More Ways Coffee Is Good for You
A new study published in Nature Communications reveals that coffee consumption influences the gut-brain axis by modifying the gut microbiome, reducing inflammation, and affecting mood, with effects observed in both caffeinated and decaffeinated varieties. Researchers found that coffee promotes specific beneficial bacteria and reduces inflammatory markers, while also impacting emotional well-being and cognitive functions. The study highlights that many of coffee's health effects are due to bioactive compounds beyond caffeine.
- ▪Coffee consumption modifies the composition of the gut microbiome, increasing bacteria like Eggerthella species and Cryptobacterium curtum, which support gut health.
- ▪Both caffeinated and decaffeinated coffee reduce perceived stress and depressive symptoms, with caffeinated coffee improving anxiety and attention, while decaf benefits memory and sleep quality.
- ▪Coffee consumption is linked to lower levels of inflammatory markers, and these effects partially persist even without caffeine.
- ▪Abstaining from coffee for two weeks led to increased inflammation and reduced emotional reactivity, which reversed upon resuming intake.
- ▪The study involved 31 regular coffee drinkers and 31 non-drinkers, with participants suspending and then resuming coffee intake to assess its effects.
