Many children – and adults – go through phases of being selective about food. But sometimes restrictive eating goes beyond typical “picky eating”. One condition that can cause significant food avoidance is Avoidant/Restrictive Food Intake Disorder (ARFID).
Understanding the difference between ARFID vs picky eating can help parents, carers, and professionals recognise when someone may need additional support.
What is ARFID?
Avoidant/Restrictive Food Intake Disorder (ARFID) is a relatively new eating disorder that was formally recognised in 2013.
People with ARFID avoid certain foods or food groups, or significantly restrict how much they eat. Unlike many other eating disorders, ARFID is not linked to concerns about body weight, body shape, or appearance.
Instead, the restriction usually occurs for other reasons, such as sensory sensitivities, fear of negative food experiences, or a lack of interest in eating.
ARFID is often described as an “umbrella term” because it can include several different types of eating difficulties, which may overlap and often occur at the same time.
1. Sensory Sensitivity
Some people with ARFID avoid foods because of their texture, taste, smell, or appearance. These sensory differences can make unfamiliar foods feel overwhelming or unsafe.
As a result, individuals may rely on a small number of familiar foods and strongly prefer specific brands or food presentations.
2. Fear After Bad Past Experiences
For some individuals, ARFID develops after a scary or uncomfortable experience with food, such as choking, vomiting, or having an allergic reaction.
They may avoid foods that remind them of that experience, or become anxious about eating in general.
3. Lack of Interest in Eating
Some people with ARFID have low appetite or limited interest in food. They may rarely feel hungry, feel full very quickly, or see eating as a chore.
In busy daily life, they may even forget to eat altogether.
ARFID vs Picky Eating
ARFID is a psychiatric disorder, so it’s important to understand how it differs from typical picky eating.
Many individuals with ARFID have underlying biological traits, such as sensory sensitivities or anxiety around food. Initially, avoiding certain foods may feel like a logical or protective response. Over time, however, these patterns can become deeply ingrained and very difficult to change.
Normal Picky Eating in Children
From around six months of age, children begin learning to eat a wide range of foods. Personality plays a role in how adventurous someone is with food, and some level of selectivity is completely normal.
In fact, most children go through a phase called food neophobia.
The Neophobic Stage
Food neophobia refers to a stage where children are hesitant or fearful about trying new foods. They may refuse foods based on appearance, saying things like “it looks wrong”.
This stage often begins around two years old. Parents might notice a child suddenly refusing foods they previously enjoyed or rejecting foods due to small details, such as:
Spots on a banana
A broken biscuit
Food touching on the plate
For most children, this stage naturally resolves by around age five.
However, for some individuals the pattern of avoidance persists and becomes more extreme. When restrictive eating continues into later childhood or adulthood and is linked to deeper biological or psychological factors, it may indicate ARFID rather than typical picky eating.
When Does Picky Eating Become ARFID?
From a clinical perspective, selective eating may be considered ARFID rather than picky eating when it begins to have a significant impact on health or daily life.
This may include:
Nutritional or Growth Concerns
Nutritional deficiencies
Being underweight
Slowed or limited growth in height
Delayed physical development or puberty
Significant Impact on Daily Life
Avoiding social events involving food
Difficulty attending school, work, or social activities
Anxiety around meals or eating environments
When restrictive eating begins to affect physical health, emotional wellbeing, or social participation, professional assessment may be needed.
Signs of ARFID to Look Out For
ARFID can present in many different ways, and individuals may experience several overlapping factors that influence their eating.
Some common signs include:
A Very Limited Range of Foods
Many individuals with ARFID eat fewer than ten foods and find it extremely difficult to try new ones.
Foods may share similar sensory properties such as:
Texture
Appearance
Smell
Temperature
Strong brand preferences are also common, for example only eating one specific brand of chicken nuggets.
Difficulty Eating Socially
People with ARFID may struggle to eat in different environments or settings, even when familiar foods are available.
Sensitivity to the Eating Environment
Eating can become stressful if the environment feels overwhelming. This might include:
Loud noise levels
The smell of other foods
Being around others while they eat
Strong Reactions to New Foods
The presence of unfamiliar foods can trigger a disgust response, which may include:
Gagging
Retching
Intense anxiety
Leaving the table
Avoidance After Negative Food Experiences
Some individuals suddenly stop eating certain foods after experiences such as choking, vomiting, or feeling ill after eating.
Fear-Based Food Avoidance
Concerns about contamination or food safety may also lead to increasing restriction.
These patterns may develop gradually, with foods slowly disappearing from the diet, or they may appear suddenly, following a negative food experience.
Why ARFID Is Different From Other Eating Disorders
One of the key differences between ARFID and other eating disorders is the underlying motivation.
In conditions such as anorexia nervosa or bulimia, food restriction is usually related to concerns about body weight or shape.
With ARFID, however, food avoidance is typically driven by:
Sensory sensitivities
Fear of negative experiences with food
Low interest in eating
Understanding these differences is crucial for providing the right kind of support.
Supporting Professionals to Understand ARFID
Because ARFID often overlaps with neurodivergent traits, recognising and supporting individuals effectively requires specialist knowledge.
That’s why we’re proud to launch a new online course on Neurodivergence and Eating Disorders, developed in partnership with the South Yorkshire ICB.
This training helps professionals:
Recognise diverse eating disorder presentations such as ARFID
Understand how neurodivergent traits can affect eating
Provide more neuroaffirmative and inclusive support
