"This situation described above, where the intestines become compromised and foreign molecules are allowed to be absorbed is also known as “Leaky Gut” or Intestinal Permeability. This condition may be the underlying cause for a whole host of serious illnesses such as (but not limited to): Rheumatoid Arthritis, Chronic Fatigue Syndrome, Fibromyalgia, Inflammatory Bowel Disease, Auto-Immune conditions, mood disorders, food allergy, and chronic skin diseases. The cause of intestinal permeability is under scrutiny. My belief is that it is multifactor and may be caused by such things as smoking, stress, food allergies/intolerance, antibiotics, Non-Steroidal Anti-Inflammatory (or exposure to other toxic medications), alcohol, aging, increased toxic burden and much, much more."
