Thirteen out of 49 patients suspected of having specific food intolerance after withdrawal and reintroduction of specific foods, were further subjected to double blind placebo controlled food challenges. Only three of these subjects were thus shown to have proven specific food intolerance. Of the remaining 10, nine were strong 'placebo reactors'. The study suggests that a small number of patients with gastrointestinal symptoms have verifiable specific food intolerance but that a greater number have symptoms attributable to psychogenic causes.
49名在停用和重新引入特定食物后疑似患有特定食物不耐受的患者中,有13名进一步接受了双盲安慰剂对照食物激发试验。结果显示,这些受试者中只有3人被证实患有特定食物不耐受。在其余10人中,有9人是强烈的“安慰剂反应者”。该研究表明,少数有胃肠道症状的患者有可证实的特定食物不耐受,但更多患者的症状归因于心理因素。
