Picky eating is notably common and often more intense in autistic children compared to their neurotypical peers. Research shows 46% to 89% of children with autism spectrum disorder (ASD) face significant food selectivity, such as limited diets or refusal of new foods.
## Prevalence
Up to 70% of autistic children experience feeding difficulties like picky eating, far higher than in typical children. In large studies like SPARK, 16% have feeding disorders, with one in five at risk for avoidant-restrictive food intake disorder. These issues can persist into adolescence or adulthood for some.
## Key Causes
Sensory sensitivities drive much of the behavior, with hypersensitivity to textures (e.g., slimy or gritty), smells, tastes, or temperatures making foods intolerable. Other factors include gastrointestinal problems like constipation or pain (affecting nearly 50% of autistic kids vs. 18% without ASD), routine preferences, anxiety around change, and oral-motor delays.
## Strategies
Gradual exposure works best: pair preferred foods with new ones, reduce grazing to build meal hunger, and create calm environments without pressure.
