Understanding Leaky Gut and Intestinal Permeability

Leaky gut, also known as intestinal permeability, is a term increasingly discussed in the context of gut health and probiotics. Initially considered a fringe concept in medical conferences, it now represents a significant area of research with thousands of articles available on PubMed. The concept revolves around the idea that the intestine is a hollow tube from the mouth to the anus, where anything inside the intestine is technically outside the body until absorbed. The intestine acts as a gatekeeper, deciding what enters the body and what remains outside, with unabsorbed substances being eliminated as waste without entering the body.
