Psychological Dimensions of Food Allergy: A Biopsychosocial and Neuropsychological Perspective.
Review in Nutrients, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Food allergy is a chronic immune-mediated condition that must be understood not only as a biological disorder but also as a biopsychosocial condition with significant psychological and neurodevelopmental consequences. Beyond the management of acute allergic reactions, individuals living with food allergy experience ongoing threat appraisal, dietary restriction, and social constraints, shaping emotional regulation, cognition, and wellbeing. This review adopts a psychology-led biopsychosocial and neuropsychological framework to examine the mechanisms through which immune activation and food avoidance influence psychological functioning. Drawing on medical psychology, psychoneuroimmunology, and gut-brain research, we explore how threat perception, interoceptive awareness, learning processes, stress physiology, and family context interact to shape emotional and behavioural responses to food allergy. Particular attention is given to the role of risk perception, vigilance, and learned avoidance in driving anxiety and reduced quality of life. By integrating evidence across psychological and biological domains, this review argues for a more comprehensive model of food allergy that recognises the cumulative emotional and neuropsychological burden associated with living with chronic dietary risk. Greater integration of psychological perspectives within allergy care may help support adaptive coping, reduce unnecessary restriction, and improve quality-of-life outcomes for individuals and families affected by food allergy.
