Coffee doesn't just serve as a morning energy booster – according to a new study, it may have important benefits for gut and brain health.
Research conducted by APC Microbiome Ireland at University College Cork shows how decaffeinated and decaffeinated coffee positively affects gut bacteria, also bringing benefits to mood and stress levels.
The study analyzed 62 people, half of whom were regular coffee drinkers. Those who drank 3–5 cups a day abstained from drinking for two weeks, during which time significant changes were observed in their microbiome – the bacteria that live in their digestive system.
After reintroducing coffee, participants reported reduced stress, depression, and impulsivity, regardless of whether they consumed decaffeinated or decaffeinated coffee.
The study, published in Nature Communications, found higher levels of certain beneficial bacteria in coffee drinkers, which aid digestion and can fight harmful bacteria.
An increase in bacteria associated with positive emotions was also observed, especially in women.
The type of coffee seems to play a different role: decaffeinated coffee is linked to improved memory and learning, while caffeinated coffee helps reduce anxiety and improves concentration.
Experts believe that the benefits come not only from caffeine, but also from other components such as polyphenols, which have anti-inflammatory properties and protect brain cells.
According to researchers, coffee can affect how bacteria in the gut function and improve communication between the digestive system and the brain - known as the "gut-brain axis".
Coffee also helps produce dopamine, a substance associated with a sense of well-being, reducing the risk of anxiety and improving motivation.
Experts emphasize that coffee should be part of a balanced and healthy diet, offering benefits that go beyond its stimulating effect. /GazetaExpress/
