Abstract

INTRODUCTION: Food hypersensitivity (FHS), including food allergy, coeliac disease and food intolerance, is a major public health issue. The Food Standards Agency (FSA), an independent Government department working to protect public health and consumers' wider interests in food, sought to identify research priorities in the area of FHS.

METHODS: A Priority Setting Exercise was undertaken, using a methodology adapted from the James Lind Alliance - the first such exercise with respect to food hypersensitivity. A UK-wide public consultation was held to identify unanswered research questions. After excluding diagnostics, desensitisation treatment and other questions which were out of scope for FSA or where FSA was already commissioning research, 15 indicative questions were identified and prioritised by a range of stakeholders, representing food businesses, patient groups, healthcare and academia, local authorities and the FSA.

RESULTS: 295 responses were received during the public consultation, which were categorised into 70 sub-questions and used to define 15 key evidence uncertainties ("indicative questions") for prioritisation. Using the JLA prioritisation framework, this resulted in 10 priority uncertainties in evidence, from which 16 research questions were developed. These could be summarised under the following 5 themes: communication of allergens both within the food supply chain and then to the end-consumer (ensuring trust in allergen communication); the impact of socioeconomic factors on consumers with FHS; drivers of severe reactions; mechanism(s) underlying loss of tolerance in FHS; and the risks posed by novel allergens/processing.

DISCUSSION: In this first research prioritisation exercise for food allergy and FHS, key priorities identified to protect the food-allergic public were strategies to help allergic consumers to make confident food choices, prevention of FHS and increasing understanding of socioeconomic impacts. Diagnosis and treatment of FHS was not considered in this prioritisation.
