Leaky Gut: What It Is (and the Hype)
"Leaky gut" is one of the most hyped terms in wellness — blamed for everything and "cured" by expensive supplements. Here’s the honest, science-based picture.
The real concept vs the hype
Increased intestinal permeability ("leaky gut") is a real phenomenon that scientists study — the gut lining can become more permeable. But the popular idea of "leaky gut syndrome" causing every symptom, curable by specific supplements, runs far ahead of the evidence. Much of the online advice is marketing, not medicine.
What actually supports gut health
- Eat plenty of fibre and plants — feeds good gut bacteria (gut-healthy foods).
- Fermented foods (curd, chaas) and variety.
- Limit ultra-processed food, excess alcohol and unnecessary antibiotics.
- Manage stress and sleep — the gut-brain link is real.
Persistent gut symptoms deserve a real diagnosis from a doctor — not a self-diagnosis of "leaky gut." See our disclaimer.
