The Science Behind Selective/Restricted Eating

The Science Behind Selective/Restricted Eating — Educational Infographic (Printable, A2)

You will receive the printable unwatermarked version of this infographic

A compassionate, research-informed visual explaining the sensory and interoceptive roots of selective eating — it's not picky, it's protective.

This infographic covers:

• Key facts: up to 90% of autistic children experience eating differences; force, pressure and reward often increase distress
• Why it happens: sensory sensitivity, interoceptive differences, need for predictability, past negative experiences, motor/oral sensory challenges, nervous system overload
• What's actually happening: the brain scanning food for danger, uncertainty as stress, safe foods keeping the nervous system steady
• What it achieves: reduces overwhelm, keeps the child regulated, avoids pain/discomfort, restores a sense of control
• What it might look like: very limited food range, brand/colour/shape rules, sensitivity to temperature, food separation rules
• Selective/restricted eating vs. "picky eating" — clear side-by-side comparison
• Interoception and eating: how unclear internal signals affect hunger, fullness, and comfort
• How we can help — and what doesn't help (forcing, bribing, shaming, pressuring)
