Dietary habits and gut health: New scientific insights on coffee, sleep, and digestion
Recent scientific findings highlight the complex relationship between diet, gut health, and sleep. A study published in Nature Microbiology involving over 22,000 participants in the US and UK found that regular coffee consumption is linked to a significant increase in the gut bacterium Lawsonibacter asaccharolyticus. This bacterium, which may appear six to eight times more frequently in coffee drinkers, produces fermentation-derived compounds like short-chain fatty acids.
Regarding sleep, a review in the journal Clocks & Sleep notes that while certain dietary patterns like the Mediterranean diet are associated with better sleep, substances such as caffeine and alcohol can disrupt sleep architecture. Specifically, alcohol can alter REM sleep phases.
Additionally, experts clarify common misconceptions regarding post-meal drowsiness. While digestion requires energy and can cause lethargy, health professionals emphasize that this sensation is not caused by a lack of oxygen to the brain, as the body prioritizes cerebral oxygen supply even during increased digestive blood flow.
