Autoimmune diseases are on the increase. Autoimmune disease is a result of an overactive immune system. Chrohn’s disease and ulcerative colitis are examples of autoimmune diseases of the digestive system. As a large part of our immune system sits in our gut it is considered likely by many health professionals that there could be gut problems, and healing the gut would be part of their protocol for someone with an autoimmune disease. Eating fermented foods will not cure any autoimmune disease, but it may help to rebalance the microbiome in your gut which then may help an overactive immune system. It is important to consult a health professional before you embark on huge diet changes though, and to take small steps in the beginning.
