Arfid and Autism: A Practical Guide for Australians
Last updated 31 October 2026 · 8 min read · By Sarah M., Support Coordinator
In short
ARFID and autism can occur together: Raising Children Network says around 11% of autistic people might have ARFID, a pattern of avoiding or restricting food. This guide explains what ARFID is, how it differs from other eating concerns, who can help in Australia and where the NDIS fits.
Around 11% of autistic people might have ARFID, and 20-75% of autistic children might eat a limited range of foods because of taste, texture or smell (Raising Children Network).
Selective eating and ARFID are not the same thing, so a proper assessment by a health professional is the way to tell them apart.
Gluten-free and casein-free elimination diets are rated “unrateable”, so talk to a GP, paediatrician or dietitian before changing what a child eats.

What is ARFID and autism?
ARFID stands for avoidant restrictive food intake disorder, and it is something a qualified professional assesses rather than something a checklist can confirm.
Raising Children Network says around 11% of autistic people might have ARFID, so many autistic people do not.
Many autistic children eat a limited range of foods, and 20-75% might do so because of taste, texture or smell.
A narrow diet on its own is not a diagnosis, which is why an assessment matters before anyone labels it.
You may find it useful to keep a short food diary, noting what is eaten, what is refused and any sensory triggers, and bring it to the appointment.
Eating disorder and autism: how selective eating and ARFID differ
Parents often ask whether fussy eating is part of autism or something more, and the honest answer is that a clinician needs to look at the whole picture.

Autism eating disorders and ARFID: how assessment works in Australia
Assessment is a conversation with health professionals, and you can start it with your regular doctor.
1Book a GP appointment. Tell the GP what you have noticed about eating, how long it has gone on and how it affects daily life, and bring your food diary.
2Ask about a referral. Your GP can explain whether a paediatrician, dietitian, psychologist or another specialist is the right next step for you.
3Share what you know about sensory needs. Textures, smells, temperatures and mealtime settings that cause distress help the team understand the person.
4Ask what the options are. A specialist can explain the supports available and what each is meant to do, so you can decide with them.
5Keep copies of reports. Written assessments are useful later if you apply for NDIS supports or ask for a plan review.

TQN Care support workers help with personal care, community access, respite and help around the home across Sydney, Melbourne and surrounding areas (NSW & VIC). Tell us what you need and we will call you back.
Autism and anorexia: why a clinician needs to look at it
Autism and anorexia can both involve restricted eating, but they are separate questions that only a specialist can sort out.
Tell your GP if eating has changed, if there is weight loss, or if food worries are linked to how someone feels about their body.
Ask the GP or specialist to explain which diagnosis, if any, applies and what the recommended supports are.
If the person is struggling emotionally, Lifeline is available on 13 11 14, and you should call 000 if someone is in immediate danger.
Other conditions that can occur alongside autism
These figures describe autistic children, except epilepsy, which describes autistic people (Raising Children Network). They are not specific to people with ARFID.
Condition
What Raising Children Network reports
Anxiety
Around 40% of autistic children have anxiety
ADHD
An estimated 30-60% meet the criteria for an ADHD diagnosis
Depression
Diagnosed in 10-20% of autistic children
OCD
Around 10% of autistic children are thought to have OCD
Support workers can assist with everyday routines and community outings, but they do not provide treatment for eating disorders.
When to talk to a GP or specialist
Ask early if you are worried, rather than waiting to see if things change.
Eating has become much narrower over time, or foods the person used to accept are now refused.
Mealtimes cause regular distress for the person or the family.
You are worried about growth, weight, energy or the person’s overall health.
Food worries seem tied to anxiety, low mood or how someone feels about their body.
You are unsure whether something is sensory preference or a bigger concern and want it checked.
Call 000 in an emergency. For emotional crisis support, call Lifeline on 13 11 14. You can also ring Autism Connect on 1300 308 699, a free helpline open 8am to 7pm Monday to Friday.

Should I try a special diet for my autistic child? +
Raising Children Network rates gluten-free and casein-free elimination diets as “unrateable” and notes concerns about the nutritional safety of restricting a child’s diet. Talk to a GP, paediatrician or dietitian before changing what your child eats.
