This makes individuals vulnerable to pathogens that a healthy immune system easily handles, resulting in illnesses like opportunistic infections.

Is it true that 80% of your immune system is in your gut?

Yes, it's true that 70-80% of your immune system resides in your gut, making it crucial for overall immunity, as it houses vast amounts of immune cells that interact with your gut microbiota (beneficial bacteria) to distinguish between harmful pathogens and helpful microbes. This constant interaction trains your immune system, with diet playing a key role in supporting this balance through fiber, probiotics, and fermented foods, impacting everything from fighting infections to chronic inflammation and autoimmune conditions.
