Is it true that 70% of your immune system is in your gut?

Yes, it's widely cited that about 70-80% of your immune system resides in your gut, specifically within the gut-associated lymphoid tissue (GALT), which constantly interacts with the gut microbiome (beneficial bacteria) to train and regulate immune responses, making gut health crucial for overall immunity. A diverse microbiome, supported by a fiber-rich diet, helps distinguish harmful invaders from harmless substances, preventing overreactions like inflammation or autoimmune issues, while an unbalanced gut can weaken defenses, leading to frequent infections and other health problems.
