无麸质饮食是唯一被认可的乳糜泻治疗方法。应咨询营养师，因为：坚持无麸质饮食很困难；饮食的变化可能会导致膳食纤维和其他营养素的缺乏；无麸质饮食可能导致摄入更多的热量、单一碳水化合物和饱和脂肪。[63]Bledsoe AC, King KS, Larson JJ, et al. Micronutrient deficiencies are common in contemporary celiac disease despite lack of overt malabsorption symptoms. Mayo Clin Proc. 2019 Jul;94(7):1253-60.

在患者达到临床缓解前应避免食用燕麦，然后可逐渐将无小麦成分的燕麦食品添加到饮食中。有大量证据表明，未受小麦或大麦污染的燕麦对绝大多数乳糜泻患者是安全的。[107]Holm K, Maki M, Vuolteenaho N, et al. Oats in the treatment of childhood coeliac disease: a 2-year controlled trial and a long-term clinical follow-up study. Aliment Pharmacol Ther. 2006 May 15;23(10):1463-72.

在某些国家/地区，不建议将燕麦作为无麸质饮食的一部分，并且在推荐燕麦之前，应先查阅当地指南。
