Definition
Avoidant/Restrictive Food Intake Disorder is a feeding and eating disorder, recognised in DSM-5, where a child restricts what or how much they eat for reasons not driven by body image: typically sensory sensitivity, fear of choking or vomiting, or lack of interest in food. NHS guidance (NICE NG69) directs ARFID care into community paediatrics or eating disorder services depending on severity.
In context for parents
Key checkpoints
- ARFID is a DSM-5 feeding and eating disorder; restriction is driven by sensory sensitivity, fear of choking or vomiting, or lack of interest in food, not body image.
- Diagnostic threshold requires significant weight loss, nutritional deficiency, supplement / tube dependency, or marked psychosocial impact.
- Around 70% of children with ARFID are autistic.
- Multi-disciplinary input (paediatric dietetics, OT for sensory work, SaLT) is the evidenced approach; SOS (Sequential Oral Sensory) is the most common UK framework.
- Crosses the EHC needs assessment threshold where ARFID drives EBSA or where autism plus ARFID needs more than school can routinely provide.
ARFID is not "fussy eating". The diagnostic threshold is a feeding pattern that has caused at least one of: significant weight loss or failure to grow, nutritional deficiency, dependence on supplements or tube feeding, or marked psychosocial impact (cannot eat at school, cannot eat with peers). Around 70% of children with ARFID are autistic. Sensory ARFID (texture, temperature, brand-specific tolerance) is the most common presentation in UK paediatric clinics.
In a Year 2 classroom, ARFID is the child who has eaten three foods reliably for two years, who panics at a new texture, and who will go a full school day without lunch rather than eat what is provided. By secondary school it is the teenager who is iron- and B12-deficient and who can no longer eat with friends because the safe-food list is too short.
What helps is rarely exposure-pressure-reward:
- The evidence base supports multi-disciplinary input: paediatric dietetics for nutritional safety, paediatric OT for the sensory and oral-motor work (Sequential Oral Sensory, SOS, is the most common UK framework), and SaLT where oral motor or swallow is a factor.
- CBT-AR (Cognitive Behavioural Therapy for ARFID) is being rolled out at some specialist services for older children.
- Pressure to "just try it" makes typical ARFID worse.
School-side: provision often needs to be in Section F: a named eating environment (quiet, separate table, choice of safe foods, no requirement to clear the plate), staff trained not to use food consequences, and recognition that lunch refusal is not behaviour. EHC needs assessment threshold is typically met where ARFID drives EBSA or where co-occurring autism plus ARFID requires more than the school can routinely provide.
Related terms
The terms parents most often see alongside Avoidant/Restrictive Food Intake Disorder.
Sensory Processing Disorder(SPD)
Difficulty taking in, organising, and responding to everyday sensory information (touch, sound, movement, taste, smell, sight, balance, and body awareness) in a way that supports daily life.
Autism(ASC)
A lifelong neurodevelopmental condition that shapes how a person communicates, processes sensory information, and experiences the social world. Autism is a difference, not an illness.
Interoception
The internal sense that tells us what is happening inside the body: hunger, thirst, needing the toilet, heart rate, emotion. Differences in interoception are common in autism and ADHD.
Occupational Therapist(OT)
An HCPC-registered specialist who supports children to participate in everyday activities, working on fine motor skills, sensory processing, self-care, and handwriting.
Where parents ask about this
Parents usually find this page after a GP has said "she'll grow out of it", after a paediatrician has used the word ARFID for the first time, or after a school's "no packed lunch" or "must finish your meal" policy has triggered a feeding crisis. Searches include "ARFID assessment UK", "ARFID school packed lunch", and "is ARFID covered by an EHCP". A Beaakon paediatric OT or specialist SaLT can carry out a feeding assessment, write a school-side eating plan, and quantify the OT / dietetic input needed for Section F.
