Ulcerative colitis diet is which of the following?

• A. High sugar
• B. High fiber, low protein
• C. Gluten-free only
• D. Low residue, high protein high calorie

Answer: (D)

In ulcerative colitis, the diet aims to reduce stool bulk and bowel irritation while keeping nutrition adequate. A low-residue (low-fiber) diet minimizes undigested plant matter in the intestines, which lowers stool frequency and mechanical irritation. At the same time, flare-ups increase metabolic needs and can lead to malnutrition, so a diet high in protein and calories supports tissue healing and helps prevent weight loss. This combination—low-residue, high-protein, high-calorie—best fits the goal of managing symptoms during active disease and maintaining nutrition.

Other patterns aren’t as suitable during flares: high sugar can worsen diarrhea; high fiber increases stool bulk and GI workload; a gluten-free-only approach isn’t required unless there's another condition like celiac disease.
