This post is a primer on symptom logging. If you have Mast Cell Activation Syndrome (MCAS) you will likely have a list of foods that you can’t tolerate. You may have a puzzling history of reacting to certain foods in certain circumstances. But you may not have a clear idea of why. By logging your symptoms, and ideally introducing one new food or environmental trigger at a time, you can narrow down the cause of symptom flares.
