Oat bran specifically increases colon butyrate concentrations and could therefore affect the progress of the disease in patients with ulcerative colitis (UC).
Patients with UC in remission were enrolled in a controlled multicenter study and randomized to eat oat bran or low-fiber wheat products.
Ninety-four of the enrolled patients ( = 47 for both groups) completed the 24-week study. The oat bran group had significantly ( 0.05) higher fecal butyrate concentrations and lower serum LDL levels, while deterioration of gastrointestinal symptoms was prevented, and subjective health maintained. The control diet significantly ( 0.05) increased obstipation, reflux, and the symptom burden and had no effects on butyrate or LDL-cholesterol. The relapse rate was the same for both diets.
Oat bran was well tolerated when given to patients with quiescent UC.
燕麦麸能特异性地提高结肠中丁酸盐的浓度，因此可能会影响溃疡性结肠炎（UC）患者的疾病进展。
处于缓解期的UC患者被纳入一项对照多中心研究，并随机分为食用燕麦麸组或低纤维小麦制品组。
94名入组患者（两组各47名）完成了为期24周的研究。燕麦麸组的粪便丁酸盐浓度显著更高（P<0.05），血清低密度脂蛋白水平更低，同时预防了胃肠道症状的恶化，并维持了主观健康状况。对照饮食显著增加了便秘、反流和症状负担（P<0.05），且对丁酸盐或低密度脂蛋白胆固醇没有影响。两种饮食的复发率相同。
对于静止期UC患者，给予燕麦麸耐受性良好。
