Microbiome and nutrition in autism spectrum disorder: current knowledge and research needs
Gut bacteria and diet in autism: what we know and what still needs study
AI simplified
Abstract
Autism spectrum disorder (ASD) is the fastest growing neurodevelopmental disorder in the United States.
- Environmental factors may contribute to the rising diagnosis rates of ASD alongside genetic risks.
- Abnormalities in gut bacteria composition and microbial metabolites have been observed in children with ASD.
- Gastrointestinal discomfort, food selectivity, and picky eating patterns are commonly reported in children with ASD.
- Mechanisms involving nutrition, gut bacteria, and ASD symptoms may operate through immune, hormonal, or neuronal pathways.
- Current evidence regarding the gut environment and nutritional status of children with ASD is reviewed.
- Future studies are needed to explore the relationship between diet and gut bacteria in children with ASD.
