Approximately 70% of the body’s immune cells are located in the gut-associated lymphoid tissue (GALT). When the intestinal barrier becomes compromised often referred to as increased intestinal permeability, it allows microbial fragments, toxins, and undigested food antigens to cross into the bloodstream. This activates the immune system and can drive low-grade, chronic inflammation. As a result, the integrity of the gut influences not only digestion, but also immune regulation, metabolic function, and overall systemic health.
