I usually just wait and offer the food again in 30 minutes to an hour. My son is nonverbal so sometimes I change the entree if possible if it's rejected the 2nd time. He was very picky when he was younger and refused almost everything but hot dogs and eggo waffles but now eats a wide variety of foods.

Why Autistic Individuals Refuse Foods

• Sensory Sensitivities: Heightened reactivity to a food's texture, taste, smell, temperature, or appearance can make certain items (like vegetables or meats) feel intensely unpleasant or overwhelming.
• Rigidity and Need for Sameness: An insistence on routines can mean rejecting a safe food if the brand, packaging, shape, or preparation changes even slightly.
• Gastrointestinal (GI) Discomfort: Issues like acid reflux, constipation, bloating, or abdominal pain affect nearly half of autistic individuals and can cause them to associate eating with pain or fear.
• Anxiety and Fear: Fear of choking, vomiting, or trying unfamiliar items (often overlapping with ARFID or Avoidant Restrictive Food Intake Disorder) can trigger severe distress or gagging.
• Interoception Differences: Difficulty interpreting internal body signals can lead to a general lack of interest in food or forgetting to eat.

Effective Strategies to Help

• Rule Out Medical Issues: Consult a pediatrician first to check for physical causes like constipation, reflux, or oral-motor/jaw weakness.
• Use Food Chaining: Gradually introduce new foods that share similar properties (such as color, texture, or brand) with foods the person already accepts.
• Low-Pressure Exposure: Allow the individual to interact with food through looking, touching, smelling, or licking without forcing them to take a full bite.
• Maintain Predictable Routines: Set consistent meal and snack times in a low-distraction environment to lower anxiety.
• Involve a Specialist: Partner with an occupational therapist specializing in feeding or a registered dietitian (such as resources via Autism Speaks) to address nutritional gaps safely.
