What is leaky gut? The digestive tract is where food goes to, be absorbed. When we eat bad foods, and our didgestive tract can not absorb the foods we eat, the gut begins to leak the undigested materials into the blood stream outside of the intestinal wall. When this happens, gastrointestinal distress occurs. Needless to say, our digestive system is not functioning well, and neither is our immune response. Disease and sickness occurs. This may be temporary. But if it’s not, consult your doctor.
