儿童花生过敏减少16%,靠的是“以毒攻毒”?
截至目前,食物过敏尚无有效根治方法。避免食用或接触过敏原,是预防发病和急诊抢救的最有效措施。但有些国家“反其道而行”。在近日举办的“2021年度美国过敏、哮喘和免疫学学会在线年会”上,澳大利亚和美国等研究人员做主题报告,都提出:花生过敏通常在儿童时期就会发病,然后伴随终生。从干预和治疗看,或该提倡让婴幼儿尽早接触花生。易过敏食物,1岁内就该吃2016年,全球儿童食物过敏率第一的澳大利亚,修改婴幼儿喂养指南,称在6个月-1岁期间,不论婴儿是否有湿疹等过敏性疾病,都应给其尝试花生、鸡蛋和乳制品等高致敏食物,以降低未来发生食物过敏的几率。此后,该国婴幼儿阶段的花生摄入量大幅增加。2019年,澳大利亚研究发现,近90%的婴儿在出生后第1年内,吃过花生。而3年前,这一比例不足30%。在“2021年度美国过敏、哮喘和免疫学学会在线年会”上,墨尔本默多克儿童研究所教授维多利亚·索里亚诺(Victoria Soriano)介绍澳大利亚最新的儿童花生过敏患病率研究。结果显示,2007-2011年,澳大利亚儿童花生过敏率为3.1%;喂养指南调整后,2018-2019年,这一比率降至2.6%,降幅达16%。“由于生活方式改变和移民因素,如果不改变喂养方式,澳大利亚的儿童花生过敏患病率本该在过去几年大幅增加。”维多利亚·索里亚诺表示。
