Your gut controls your skin glow: Dietitian Sonia Narang

Sonia Narang calls the gut the "glow switch" for your skin. When junk food damages the intestine's permeability, undigested food and toxins leak into the bloodstream. When the brain can't flush these toxins through sweat, it pushes them out through your pores as acne. In her view, if your skin is breaking out, your gut bacteria are losing the battle.
