Research shows 70% of our immune system in is our digestive tract. When the gut is out of balance and leaky gut is present, undigested peptides from the foods we eat, and toxins we are exposed to, end up in the blood stream. This creates extra work for the liver as the liver is the only organ that can purify the blood. And the blood is our life source. When the liver becomes overburdened and unable to filter efficiently, these substances are left in the bloodstream triggering an immune response. This contributes to food and environmental sensitivities as well as an increase in symptoms.
