Abstract
<jats:p>The principles of dietetic care for autistic children and young people (CYP) are the same as for non‐autistic CYP. Autistic children often have other neurodivergences and mental health conditions, including intellectual/learning disability, attention deficit hyperactivity disorder, depression and anxiety. Standard growth and biochemistry reference ranges apply to autistic CYP. Common dietary issues for autistic CYP include avoidant and restrictive feeding problems, anorexia nervosa and parental wishes for dietary manipulation to improve their child's developmental trajectory, health or well‐being. Effective outcome monitoring and evaluations should centre the experience of the autistic CYP and their families and take a holistic approach to improving their quality of life, including supporting the parent–child relationship, and the parent or carer's well‐being too.</jats:p>
