Case reports suggest one such associated feature, food selectivity, increases risk for nutritional deficiencies; however, little attention has been given to prevent and treat nutritional deficiencies in youth with autism spectrum disorder. Single case report. This single case report presents a child with autism spectrum disorder and food selectivity difficulties that resulted in severe vitamin C deficiency. Although eventually corrected, the nutritional deficiency was debilitating, required invasive interventions, and resulted in significant social/emotional and economic costs. We review the course of treatment and highlight strategies to prevent and more effectively treat nutritional deficiencies in youth with autism spectrum disorder %K autism spectrum disorder %K food selectivity %K nutritional deficiency %K prevention %K treatment %U https://journals.sagepub.com/doi/full/10.1177/0091217418791443
