Abstract
Background: Autism spectrum disorder (ASD) is a neurodevelopmental disorder that manifests in the first years of life, with a complex pathogenesis influenced by biological, genetic and epigenetic factors. Many children with ASD display marked food selectivity, often restricting themselves to a narrow range of foods. The problems associated with feeding children with ASD can vary widely, from mild cases that pose no immediate health risks, to more severe situations with a risk of malnutrition or, conversely, overeating. This scoping review aims to provide an in-depth overview of the frequency, nature and factors related to food selectivity in children with autism.
Aim: To comprehensively review the literature on food selectivity in ASD.
Methods: A systematic review of the literature was conducted using the PubMed, Web of Science and EBSCO databases, to identify articles published in English from 2014 until 2024. Studies on a sample diagnosed with ASD and food selectivity were included. The selected databases were chosen for their broad coverage of the scientific literature. These databases represent reliable sources of high-quality articles, ensuring a comprehensive and up-to-date search.
Results: We evaluated 222 studies on food selectivity in autism, from which duplicates were removed and unrelated titles were filtered out. Finally, 9 articles were included in the review. Five articles provide a general overview of the phenomenon, analysing its nature and factors. Two studies delve into sensory sensitivity, in particular the impact of food textures, tastes and smells. Finally, two studies focus on problem behaviour during mealtimes.
Conclusion: Children with ASD have greater food selectivity than the neurotypical population. The diet should contain a greater variety of fruit, vegetables, yoghurt, while reducing the consumption of rice and pasta.
