I want to share with the Community what diet CURED the IBS-D that had tortured me for half my life! It may or may not work for everyone, but it healed my IBS within two days; four months later, I am still healed. I now know to eat LOW-RESIDUE. I avoid high-fiber food. I avoid nuts, seeds, fruit/vegetable skins, whole grains, corn, peas, beans, etc. I eat fruit only rarely, and I am able to eat raw salads in moderation. I eat as much as I want of refined starches like white bread, white rice, white pasta, fried potatoes, whipped potatoes. The other key element to this cure is to get plenty of acidic food/drink such as limeade, lemonade, vinegar, tomato juice, and tomatoes (the soft seeds in tomatoes do not hurt me). I had suffered for 31 years with debilitating abdominal cramps, chronic diarrhea, and severe extreme intestinal gas. Good luck-- this works perfect for me, and it just might be the cure you are hoping to find.
