“Your gut has its own immune system, the “gut-associated lymphatic tissue” (GALT). It represents 70 to 80 percent of your body’s total immune system. This speaks volumes about the importance—and vulnerability—of your gut. If the events that take place in the gut weren’t so critical to life, then the majority of your immune system wouldn’t have to be there to guard and protect it.”
