🥦 If you have ulcerative colitis, watch out for insoluble fiber!
While fiber is essential, insoluble fiber—found in whole grains, nuts, seeds, legumes, and the skins of fruits & veggies—can worsen symptoms during UC flares, like cramping, bloating, and diarrhea.
✅ Key tips:
• Reduce insoluble fiber during flare-ups, and go easy on foods like whole-grain breads, raw broccoli stems, nuts, seeds, corn, berries, and legumes.
• Focus on soluble fiber instead—think peeled apples, bananas, oats, cooked carrots—and try cooking or blending foods to make them gentler.
• Once in remission, gradually reintroduce fiber, aiming for a balanced intake with guidance from a dietitian.
💡 Bottom line: Insoluble fiber’s coarse nature can irritate an inflamed colon, while soluble fiber supports healing and gut health. Tailoring fiber intake to your flare-up status can make a real difference.
It can trigger symptoms and make flare-ups harder to handle.
