- BackgroundThe 2014 estimates of prevalence of food allergy (FA) in Europe published by the European Academy of Allergy and Clinical Immunology included only the eight so-called big foods (cow's milk/egg/wheat/soy/peanut/tree nuts/fish/shellfish). Those estimates have recently been updated. Complementing this, we sought to identify and estimate the prevalence of allergy to other foods that have been reported during the last decade.MethodsSix databases were searched for studies published 2012-2021. Random-effects meta-analysis was performed to derive pooled prevalence of allergy to each food.ResultsTwenty-seven studies were included, containing a total of 66 FAs. Among the most frequently reported FAs, the lifetime and point prevalence range of self-reported kiwi allergy was 0.1%-1.0% and 0.2%-8.1%, respectively, while the food challenge (FC)-verified kiwi allergy point prevalence range was 0.01%-0.10%. The point prevalence range for self-reported peach allergy was 0.2%-3.2%, while the range for FC-verified peach allergy was 0.02%-0.05%. The lifetime and point prevalence range for self-reported tomato allergy was 0.01%-1.8% and 0.2%-2.1%, respectively.ConclusionAllergy to some foods traditionally not considered important are now emerging as relevant FAs. The focus on FA in Europe should not be limited to the so-called eight big FA, but extended to other types of foods which need to be considered both for clinical purposes and population risk assessment.

- Food allergy (FA) is increasingly reported in Europe, however the latest prevalence estimates were based on studies published a decade ago. The present work provides the most updated estimates of the prevalence and trends of FA in Europe. Databases were searched for studies published between 2012 and 2021, added to studies published up to 2012. In total, 110 studies were included in this update. Most studies were graded as moderate risk of bias. Pooled lifetime and point prevalence of self-reported FA were 19.9% (95% CI 16.6-23.3) and 13.1% (95% CI 11.3-14.8), respectively. The point prevalence of sensitization based on specific IgE (slgE) was 16.6% (95% CI 12.3-20.8), skin prick test (SPT) 5.7% (95% CI 3.9-7.4), and positive food challenge 0.8% (95% CI 0.5-0.9). While lifetime prevalence of self-reported FA and food challenge positivity only slightly changed, the point prevalence of self-reported FA, sIgE and SPT positivity increased from previous estimates. This may reflect a real increase, increased awareness, increased number of foods assessed, or increased number of studies from countries with less data in the first review. Future studies require rigorous designs and implementation of standardized methodology in diagnosing FA, including use of double-blinded placebo-controlled food challenge to minimize potential biases.
