Autism spectrum disorders (ASD) arise from a complex interplay between genetic predisposition and various environmental factors, leading to diverse and intricate conditions. Over recent decades, there has been a noticeable increase in autism prevalence. Thus, the main objective of this exploratory study is to adopt both descriptive and cross-sectional methodologies and delve into the nutritional and metabolic profiles of 20 Moroccan children diagnosed with autism spectrum disorder (ASD). Based on the descriptive statistical methods and the chi-square (χ2) test, we analyzed the results of the study, which involved around 100 biological parameters conducted in the United States (Mosaic Diagnostics) .The results revealed that variations in neurotransmitter production, dysbiosis, yeast overgrowth, elevated oxidative stress, mitochondrial dysfunction, increased oxalate levels, and deficiencies in vitamins and minerals among the children were connected to heavy metal poisoning and intoxication. These findings underscored the link between metabolic profiles and heavy metal poisoning, highlighting the need for individualized and multidisciplinary care approaches for children with ASD. Further research and controlled clinical trials are necessary to validate these interventions comprehensively.
