Role of Multi-Cereal in Nutritional Strategies in Children with Autism

Autism in a neurodevelopmental disorder impairing the social communication, social interaction, and restricted activity, that is usually diagnosed in the first 3 years of life. There has been a growing interest understanding the significance of adopting a gluten-free and casein-free (GFCF) diet. Variations in the interactions between the gut microbiota and the brain are important in several brain-related illnesses, like autism. Autism sufferers typically exhibit an imbalance in the composition of their gut flora, which may be a factor in their gastrointestinal symptoms. In people with ASD, this imbalance also compromises the integrity of the intestinal barrier and the blood–brain barrier (BBB). Toxins, proinflammatory cytokines, and partially digested peptides are among the substances that can pass through the blood–brain barrier and enter the bloodstream, ultimately reaching the central nervous system. The build-up of these chemicals may have detrimental effects on brain activity. According to one theory, partially digested peptides may aggravate behaviors particular to autism and lessen pain sensitivity by functioning as opioid agonists. Dietary therapies, especially elimination diets, are thought to be complementary therapies for this illness. The Gluten-Free Casein-Free (GFCF) diet is one such diet that calls for removing proteins from the regular diet, such as casein and gluten. Nevertheless, there is a paucity of research clarifying the mechanism of the GFCF diet and demonstrating its therapeutic effects on individuals with autism. The opioid theory is consistent with this lack of data. This chapter aims to investigate the gastrointestinal and behavioural problems frequently associated with autism, possible mechanisms of action of GFCF diets, and efficacy of these elimination diets.
