What is ARFID? Avoidant/Restrictive Food Intake Disorder Explained

Most children go through phases of being selective about food. But for some children - and adults - food avoidance goes much further than typical fussiness and significantly affects their nutrition, daily life and wellbeing. This is known as ARFID: Avoidant/Restrictive Food Intake Disorder.

What is ARFID?

ARFID is a feeding and eating disorder characterised by persistent avoidance or restriction of food based on sensory features (such as texture, colour or smell), fear of negative consequences (such as choking or vomiting), or a general lack of interest in food.

Unlike many other eating disorders, ARFID is not driven by concerns about weight or body image. It is about the experience of food itself - and for those affected, even small amounts of the "wrong" food can trigger significant distress.

ARFID can affect people of all ages, but it often begins in childhood and may go unrecognised for years.

How ARFID differs from fussy eating

Fussy eating is common in young children and typically resolves over time with patience and repeated exposure. ARFID is different in several important ways:

• The range of accepted foods is severely limited - sometimes to fewer than 10 or 20 foods
• Attempts to introduce new foods cause significant distress, not just resistance
• The restriction is affecting nutrition, growth, or the ability to participate in social eating
• It has persisted over a long period and isn't improving with the usual strategies

If your child's food refusal is affecting their nutrition, growth, family mealtimes or social life, it's worth seeking specialist advice rather than waiting for them to "grow out of it."

What causes ARFID?

ARFID often has more than one cause. Common contributing factors include:

• Sensory sensitivities - heightened sensitivity to texture, taste or smell
• A previous negative experience with food, such as choking or vomiting
• Anxiety around mealtimes or new foods
• Neurodevelopmental differences such as autism or ADHD, which are common in people with ARFID
• A history of feeding difficulties in infancy, including oral aversion

What does support look like?

ARFID is a complex condition that typically requires a multidisciplinary approach. A full team might include a dietitian to assess nutritional needs, a clinical psychologist or CAMHS involvement where anxiety is significant, a paediatrician to rule out underlying medical factors, and a Speech and Language Therapist.

An SLT's role within that team is specific: to assess whether there are any oral motor, sensory, or swallowing factors contributing to the food refusal, and to help clarify whether what a child is experiencing reflects typical fussy eating, a sensory feeding difficulty, or something that meets the threshold for ARFID. That distinction matters, because the support looks very different depending on the answer.

If you're unsure whether your child's eating is within normal limits or something more significant, a paediatric feeding assessment is a good starting point for getting some clarity.
