Autism spectrum disorder symptoms mitigation through the use of specific nutritional approaches: a scope review
Main Article Content
Abstract
Introduction: The autism spectrum disorder is a neurodevelopmental disorder and, according to DSM-5, it is characterized by social communication deficit and repetitive and/or restrictive behavior patterns. Autism spectrum disorder has been related with certain eating patterns and habits, choosing, in most of the time, for fatty, hypercaloric, sodium rich and non-nutritive food. Objective: To analyze and discuss the most significant findings over autism spectrum disorder symptoms mitigation through specific nutritional approaches. Data sources: A literature review, from the last 2 years, was carried out following the scoping review methodology and Virtual Health Library, PubMed and Scielo databases. The following descriptors were used: “Nutritional Status” OR Diet AND “Autism Spectrum Disorder”. At the end of the selection process, 19 articles remained to be analyzed. Data synthesis: There is an intimate relation between autism spectrum disorder patients and a proven food selectivity. This review found positive results regarding symptoms mitigation during pre and probiotics use. When it comes to vitamin supplementation and specific diets (ketogenic, gluten and casein free), results were inconclusive. Conclusion: Wider and more rigorous clinical trials are necessary to establish the real effect that specific diets have on autism spectrum disorder symptoms mitigation.
