“Zonulin is the primary infection facilitator.”
I had never heard of such a critter as Zonulin. It was interesting for me to discover that it controls the permeability of the cells of the intestine. I learn something new every day.
Have you noticed that humans lead the animal kingdom in autoimmune disease as well? Zonulin passes all sorts of antigens into the lymph and blood systems including food opioids, the cause of most autoimmune diseases. It’s a nasty side effect of evolution’s rush to eliminate overcrowding through death and improvement.
