“Leaky gut” isn’t a real medical diagnosis, not according to the gastroenterologists that I know, anyhow. It’s mostly a diagnosis that naturopaths and other quacks give to people with depression and other problems. They target people that have felt bad for a long time, and are reaching out for something to help them. These quacks give them a name for why they feel bad, and say they can help them with dietary advice and supplements. It’s basically just a way for them to cash in on the “gut microbiome” craze.
