People with non-coeliac gluten sensitivity (NCGS) report gastrointestinal symptoms after gluten consumption in the absence of coeliac disease or wheat allergy. However, the mechanism by which gluten can induce gastrointestinal symptoms in individuals with NCGS is unclear. In a new study published in The Lancet Gastroenterology & Hepatology, researchers conducted a randomized, double-blind study that assessed whether gluten-induced gastrointestinal symptoms were influenced by expectancy — that is, whether participants expected to consume gluten or not.

麸质摄入预期对非乳糜泻麸质敏感性的影响

非乳糜泻麸质敏感性 (NCGS) 患者在没有乳糜泻或小麦过敏的情况下食用麸质后会出现胃肠道症状。然而，麸质诱发 NCGS 个体胃肠道症状的机制尚不清楚。在《柳叶刀胃肠病学和肝脏病学》上发表的一项新研究中，研究人员进行了一项随机、双盲研究，评估麸质引起的胃肠道症状是否受到预期的影响，即参与者是否预期食用麸质。
