What are tight junctions?

“Gatekeeper in the Gut”

To use an everyday description, a rock-solid football defensive line protects the opposing team from scoring any points because it has “tight junctions.” In our pets’ immune system, these same kinds of tight junctions keep things out of the bloodstream that should not be there and at the same time allow nutrients to enter the bloodstream.

There is a growing body of well-developed science that demonstrates that the tight junction barrier in the gut can be degraded with exposure to gluten and glyphosate (the main chemical in commercial herbicide).
