I have severe Crohn's disease and was not responding to any medications (Remicade, Humira, Stelara, Entyvio). I tried them all and still had blood in my stools every day, extreme urgency, bloating, gas, stomach pain, weight loss, joint/muscle pain, chronic fatigue, anxiety, etc. I even tried many diets you would see on the internet (SCD diet, paleo, vegetarian). Nothing seemed to work. Today, all those above symptoms are gone for the most part! The food sensitivity test was a game changer for me. I was eating all the wrong foods thinking they were healthier alternatives but I was sensitive to them. The key for me was to introduce foods as slowly and methodically as I could and pay attention to how my body was reacting to them. You cannot rush this step! Once I knew which foods I could tolerate everything started improving for me.
