ARFID in Children: Signs, Symptoms and How It Differs From Picky Eating
Is your child’s eating more than just “fussy”?
Learn about ARFID, how it differs from typical picky eating, and when it may be time to seek professional support.
“They only eat about five foods.”
“They refuse anything that looks different.”
“They used to eat that, but after they vomited, they won’t touch it anymore.”
“They’re not underweight, so surely it can’t be an eating disorder?”
If any of these sound familiar, you may have wondered whether your child is fussy/picky eater or whether something more significant is going on.
Avoidant/Restrictive Food Intake Disorder (ARFID) is a recognised eating disorder that can affect children and adolescents. It involves significant restriction or avoidance of food that is not driven by concerns about body weight or shape.
Instead, children with ARFID may restrict their eating because of sensory sensitivities, very little interest in eating, or fear of unpleasant consequences such as choking, vomiting or pain.
Importantly, ARFID can look very different from one child to another. Some children eat a reasonable amount of food but have an extremely limited range of foods. Others struggle to eat enough overall. Some may have nutritional deficiencies or growth concerns, while others may appear to be growing normally.
So, how do you know when picky eating may be something more?
What is ARFID?
ARFID stands for Avoidant/Restrictive Food Intake Disorder.
It is a feeding and eating disorder where a child avoids or restricts food intake to a degree that causes significant nutritional, medical or social consequences.
Unlike anorexia nervosa, ARFID is not driven by a fear of gaining weight or concerns about body size or shape.
There are three commonly recognised drivers or presentations of ARFID:
1. Sensory sensitivity
Some children experience food very differently from other people.
They may be particularly sensitive to:
textures
smells
tastes
temperatures
colours
appearance
foods touching each other
changes in familiar brands or packaging
For these children, a food that looks, smells or feels “wrong” can be genuinely stressful and difficult to tolerate.
This can sometimes look like extreme picky eating. A child may accept one particular brand of chicken nuggets but refuse another brand, even though the foods appear almost identical to a parent.
2. Fear of aversive consequences
Some children avoid food because they are worried something bad will happen when they eat it.
For example, a child may become frightened of eating after:
choking
vomiting
experiencing significant reflux or abdominal pain
having an allergic reaction
gagging
becoming unwell after eating a particular food
A child who once ate a wide variety of foods may therefore develop a much more restricted diet following a frightening or painful experience.
The fear isn't necessarily obvious to adults. Children may simply say, “I don't like it,” when what they are actually communicating is that they are worried about what might happen if they eat it.
3. Low interest in eating
For other children, eating simply doesn't feel very important.
They may:
rarely feel hungry
become distracted easily at mealtimes
forget to eat
eat very small amounts
take a long time to finish meals
become full after only a small amount
show little interest in food
Research continues to explore the different mechanisms behind these presentations, and children can have more than one driver at the same time.
ARFID vs picky eating: what's the difference?
Picky eating is extremely common during childhood.
Many toddlers and preschoolers go through periods where they become more selective about food. They may reject foods they previously enjoyed, prefer familiar foods or suddenly decide that vegetables or meats are ‘yuck’.
This doesn't automatically mean they have ARFID.
One of the important differences is the impact that the restriction has on the child.
A child may be selective but still eat enough food, meet their nutritional needs, continue to grow appropriately and participate comfortably in social situations involving food.
ARFID involves restriction or avoidance that has a more significant impact.
For example, a child may experience:
inadequate energy intake
nutritional deficiencies
faltering growth or weight loss
reliance on oral nutrition supplements or tube feeding
significant anxiety around eating
difficulty eating at school or parties
avoidance of restaurants or social occasions involving food
significant distress around mealtimes
It is therefore not simply about counting how many foods a child eats.
There is no specific number of foods that automatically means a child has ARFID.
In research and clinical practice, very limited variety (for example, fewer than 15–20 foods or avoidance of entire food groups) is often used as a red flag, but it is not a diagnostic threshold on its own. A child eating 20 foods may have significant nutritional or psychosocial difficulties, while another child eating a relatively small number of foods may still be meeting their nutritional needs.
The overall picture matters.
Can a child have ARFID if they aren't underweight?
Yes.
This is an important misconception.
Although inadequate growth or low weight can occur with ARFID, children with ARFID can be across the weight spectrum. A systematic review of physical health complications found that children and young people with ARFID can experience nutritional and medical complications even when they are not underweight.
A child's weight is therefore only one part of the assessment.
A child may have an apparently healthy weight while still having:
iron deficiency
inadequate calcium or vitamin D intake
inadequate fibre
inadequate protein or energy intake
low intake of fruit and vegetables
insufficient dietary variety
dependence on supplements to meet nutritional requirements
Growth needs to be considered over time, including weight, height and pubertal development, rather than relying on a single weight measurement. This is particularly important during periods of rapid growth and puberty.
What does ARFID look like in children?
Every child with ARFID is different, but some common signs include:
Food variety is extremely limited
Your child may eat only a small number of foods and strongly resist adding new ones.
They may have very specific rules about what they will eat, such as:
only one brand
only a particular shape
foods cannot touch
foods must be a particular colour
foods must be prepared in a specific way
foods need to be completely smooth or completely crunchy
Foods disappear from the diet
Sometimes the issue isn't that a child never ate many foods.
They may have previously eaten a reasonable variety but gradually stopped eating foods.
Parents may notice that the list of accepted foods is getting smaller and smaller.
New foods cause significant distress
Some children become extremely anxious when presented with unfamiliar foods.
They may gag, cry, panic, leave the table or become distressed simply by having a new food nearby.
Eating takes a long time
A child may take an unusually long time to finish meals or snacks, particularly if they have difficulty eating enough volume.
Your child rarely seems hungry
Some children with ARFID have very little interest in eating.
They may happily continue playing rather than stopping for lunch, need frequent reminders to eat or seem satisfied after only a small amount of food.
Eating has become socially difficult
Food restriction can make everyday activities challenging.
Your child may worry about: school camps, birthday parties, sleepovers, restaurants, holidays, eating at friends' houses, school canteens etc
They may avoid situations where their safe foods aren't available.
There are physical or nutritional consequences
These might include poor growth, weight loss, constipation, fatigue or nutritional deficiencies.
However, the absence of these symptoms does not necessarily mean there isn't a problem.
ARFID, autism and sensory sensitivities
ARFID and autism can occur together, but being autistic does not mean a child has ARFID.
Many autistic children have sensory differences that affect eating. They may have strong preferences around texture, temperature, smell, appearance or predictability.
Some children may have a very restricted diet without meeting the diagnostic criteria for ARFID.
For others, their food restriction may be severe enough to result in nutritional, medical or psychosocial consequences consistent with ARFID.
The same principle applies to ADHD, anxiety and other neurodevelopmental or mental health conditions.
Rather than assuming that a child's eating difficulties are “because of autism” or “because they're anxious”, it is important to understand what is actually driving the eating difficulty and what impact it is having on the child.
Current research suggests that several factors can be associated with ARFID, but the causes are complex and are still being investigated. ARFID is reported more frequently in some neurodevelopmental and gastrointestinal conditions, but each child’s eating pattern and its impact need to be assessed individually.
Can ARFID develop after choking or vomiting?
Yes.
A frightening experience such as choking or vomiting can sometimes lead to a child becoming fearful of eating.
For example:
A child eats normally until they have a vomiting illness. Afterwards, they become worried that eating will make them vomit again. They begin avoiding the foods they associate with the experience. Over time, their diet becomes increasingly restricted.
Similar patterns can occur following choking, significant gastrointestinal symptoms or other unpleasant experiences with food.
For some children, the original physical problem may have resolved, but the fear associated with eating can continue.
This is one reason why understanding why a child is avoiding food is so important.
Why does ARFID matter?
Food restriction can affect much more than what appears on the dinner plate.
If a child's intake is inadequate or their diet is very limited, they may not receive enough of the nutrients needed for growth and development.
Depending on the foods excluded, this may include inadequate intake of:
iron
calcium
vitamin D
zinc
protein
essential fats
fibre
a range of vitamins and minerals
ARFID can also affect growth, bone health and overall physical health. A systematic review and meta-analysis found evidence of nutritional deficiencies, low weight and reduced bone mineral density among children and young people with ARFID.
But the impact isn't only nutritional.
Food plays a huge role in childhood social life. When eating becomes stressful, children may miss out on experiences with family and friends or feel different from their peers.
For some children, the anxiety around food can become more disruptive than the food restriction itself.
How is ARFID diagnosed?
ARFID is diagnosed using clinical assessment against the diagnostic criteria in the DSM-5-TR. There is no blood test or single assessment that can diagnose ARFID.
For children, assessment may involve a GP or paediatrician, alongside mental health and allied health professionals such as a psychologist, psychiatrist, dietitian, occupational therapist or speech pathologist, depending on the child's presentation.
A paediatric dietitian can assess nutritional intake, dietary variety, growth and potential nutritional deficiencies and can identify concerns that may warrant further assessment. A medical and/or mental health professional can then consider whether the child meets the diagnostic criteria for ARFID and whether another medical or psychological condition could better explain the eating difficulties.
You don't need to have an ARFID diagnosis before seeing a paediatric dietitian. If you're concerned about your child's restricted eating, a dietitian can be an important starting point for understanding whether they are meeting their nutritional needs and whether further assessment is recommended.
Assessment generally involves understanding:
what your child currently eats
how much they eat
how long they have been eating this way
which foods they avoid
why they avoid them
previous eating and feeding history
growth and weight history
nutritional intake
gastrointestinal symptoms
sensory factors
anxiety or fear around eating
the impact of eating difficulties on family and social life
Medical and nutritional assessment may also include blood tests or other investigations when clinically indicated.
Importantly, other medical conditions that could explain the eating difficulties need to be excluded as contributing factors.
For example, a child with significant abdominal pain, swallowing difficulties, reflux or another gastrointestinal condition may restrict their eating because eating is genuinely uncomfortable.
A thorough assessment helps distinguish these situations and identify what support is needed.
How is ARFID treated?
There is no single treatment that works for every child with ARFID.
Because ARFID can involve nutritional, sensory, psychological and medical factors, treatment is often multidisciplinary.
Depending on the child's needs, the team may include:
a paediatrician or GP
paediatric dietitian
psychologist or psychiatrist
occupational therapist
speech pathologist
gastroenterologist
other medical or allied health professionals
Psychological therapies are an important part of ARFID treatment, particularly where anxiety, fear or avoidance is contributing to the eating difficulties.
Nutrition support is also important to ensure the child's nutritional needs are being met while treatment addresses the underlying eating difficulties.
For some children, this may involve carefully planned nutritional supplementation.
The approach needs to be individualised. There is no one-size-fits-all “ARFID diet” and no single list of foods that every child with ARFID should eat.
What can a paediatric dietitian do?
A paediatric dietitian can help answer one of the questions parents often worry about most:
“Is my child actually getting what they need?”
An assessment can look at the child's overall diet rather than simply focusing on the number of foods they eat.
This may include:
assessing energy and protein intake
reviewing dietary variety
identifying potential nutrient gaps
reviewing growth patterns
considering nutritional supplements where appropriate
developing practical strategies to increase nutritional adequacy
supporting gradual food expansion
helping parents understand what is driving their child's food restriction
working alongside the child's broader healthcare team
For children with ARFID, the goal isn't simply to make them eat more foods.
The goal is to support adequate nutrition, growth, health and a more comfortable relationship with eating.
What should I do if I'm worried about my child's eating?
You don't need to wait until your child's eating becomes extremely restricted before asking for help.
Consider seeking professional advice if:
your child's list of accepted foods is becoming smaller
they are skipping meals
meals are very stressful
they are losing weight or not growing as expected
they have ongoing nutritional deficiencies
they rely heavily on nutritional supplements
they are anxious about eating
they have reduced eating following choking, vomiting or another frightening experience
food restriction is affecting school, social activities or family life
you are spending a significant amount of time worrying about whether your child is eating enough
And perhaps most importantly:
You don't have to work out whether your child has ARFID before seeking help.
If you're concerned about your child's eating, a paediatric dietitian can help assess their nutritional intake and growth and determine whether further assessment or referral to other members of the healthcare team would be appropriate.
ARFID is more than “just being fussy”
Some children are naturally selective eaters. Some go through phases of picky eating that improve with time.
But when food restriction starts to affect a child's nutrition, growth, health, emotional wellbeing or ability to participate in everyday life, it needs to be taken seriously.
ARFID isn't about a child being stubborn or a parent not trying hard enough.
Understanding the reason behind the eating difficulty is an important first step towards helping your child. An experienced paediatric dietitian can support you in understanding the ‘why’?
