It’s not just the food you eat: Environmental factors in the development of food allergies

The dramatic rise in the prevalence of food allergy and food allergy-associated anaphylaxis in the past few decades has fuelled investigative interest into understanding this puzzling trend. In this study, the authors review the question as to whether important external environmental determinants beyond dietary habits and exposure to food allergens are involved. This review will summarise our current understanding of these environment determinants, derived from the latest experimental and epidemiological research. Specifically, the role of exposures that affect skin barrier function, development of a diverse microbiome, and food processing will be reviewed. Additional exposures of concern are insufficient sunlight, endocrine disrupting chemicals and pesticides, and use of specific pharmaceutical agents that may drive or modify the risk for food allergy. Despite limitations in the quantity and quality of research to date, many new epidemiological associations and experimental data in support of this paradigm have emerged.
