Randomised controlled trials indicate early introduction and regular consumption of common food allergens in infancy can reduce food allergy risk. Few studies have explored parental and healthcare professional experiences. This systematic review examines their perspectives applying a theory\u2010informed behavioural analysis identifying key barriers influencing food allergen introduction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method<\/jats:title>\n                    <jats:p>A systematic search of seven databases was conducted in November 2025. All study designs and published primary research papers were included and screened against the inclusion\/exclusion criteria. Quantitative findings were summarised narratively and analysed alongside qualitative data.
