Most Canadian food allergy data has focused on Health Canada’s priority food allergens. This study describes which non-priority (emerging) food allergens were most commonly reported by Canadian parents and categorized/confirmed by allergists. A secondary aim was to describe severity of allergic reactions to emerging allergens. Parents reported allergic reactions to emerging food allergens experienced by their child (< 18 years) which occurred in the past 12 months, and allergists categorized/confirmed them according to likelihood of IgE-mediated food allergy. Of 68 eligible patients completing the survey, the most commonly reported emerging allergens were fruits/vegetables (58.8%), seeds (22.1%), legumes (19.1%) and other (11.8%). Median allergist ranking for legumes was ‘probable’ IgE-mediated food allergy, ‘possible’ for seeds and fruits/vegetables, and ‘unlikely’ for other. Median reaction severity was mild for legumes, and moderate for seeds, fruits/vegetables, and other. Our study highlights that non-priority food allergens, namely legumes and seeds, can lead to probable/likely allergic reactions in Canadian children. These food allergens are increasing in popularity in the Canadian diet, which could lead to increasing reports of allergic reactions. More research is needed to confirm reports of reactions to emerging allergens, and to document their inclusion as ingredients in packaged foods.

加拿大儿童对新兴食物过敏原的过敏反应

大多数加拿大食物过敏数据都集中在加拿大卫生部的优先食物过敏原上。这项研究描述了加拿大父母最常报告并由过敏症专家分类/确认的非优先(新兴)食物过敏原。次要目的是描述对新出现的过敏原的过敏反应的严重程度。父母报告了他们的孩子(<18 岁)在过去 12 个月内经历的对新出现的食物过敏原的过敏反应,过敏症专家根据 IgE 介导的食物过敏的可能性对这些过敏反应进行了分类/确认。在完成调查的 68 名符合条件的患者中,最常报告的新兴过敏原是水果/蔬菜 (58.8%)、种子 (22.1%)、豆类 (19.1%) 和其他 (11.8%)。豆类过敏症专家排名中位数是“可能的”IgE 介导的食物过敏,种子和水果/蔬菜“可能”,其他“不太可能”。豆类的反应严重程度中位数为轻度,种子、水果/蔬菜等为中等反应严重程度。我们的研究强调,非优先食物过敏原,即豆类和种子,会导致加拿大儿童可能/可能的过敏反应。这些食物过敏原在加拿大饮食中越来越受欢迎,这可能导致过敏反应的报告越来越多。需要更多的研究来确认对新兴过敏原的反应报告,并记录它们作为包装食品中的成分。可能导致加拿大儿童的过敏反应。这些食物过敏原在加拿大饮食中越来越受欢迎,这可能导致过敏反应的报告越来越多。需要更多的研究来确认对新兴过敏原的反应报告,并记录它们作为包装食品中的成分。可能导致加拿大儿童的过敏反应。这些食物过敏原在加拿大饮食中越来越受欢迎,这可能导致过敏反应的报告越来越多。需要更多的研究来确认对新兴过敏原的反应报告,并记录它们作为包装食品中的成分。
