Autoimmune Diseases and Their 13 Known Triggers

10. Nightshades

If you haven't heard of nightshades before, they're a specific group of vegetables that may trigger autoimmune diseases in some people. These vegetables are very common and included both bell and hot peppers, tomatoes, potatoes, eggplants, and chilis. For most people, these are very healthy foods, but for someone with a predisposition to autoimmune disease, eating these foods can be a trigger. They contain chemicals that set off a signal to the immune system to attack healthy cells. If you are diagnosed with an autoimmune disease, you should cut these out of your diet immediately in order to reduce the chance of flare-ups.
