Bacteria Quote by Ed Yong
““Drinking lots of alcohol makes the gut leakier, allowing microbes to more readily influence the brain. Could that help to explain why alcoholics often experience depression or anxiety? Our diet reshapes the microbes in our gut, could those changes ripple out to affect our minds? The gut microbiome becomes less stable in old age-could that contribute to the rise of brain disease in the elderly? And could our microbes manipulate our food cravings in the first place? If you reach for a burger or a chocolate bar what exactly is pushing that hand forward?””
About This Quote
The excerpt explores how alcohol and diet alter gut microbes, which may affect brain chemistry, mood, cravings, and age‑related neurological disease, proposing a gut‑brain‑behavior feedback loop.
In simple terms: Gut microbes link diet, alcohol, and mental health.
