Autism and eating disorder awareness
Eating isn’t always simple for families. It may look like buying the same trusted cracker brand every week or feeling a spike of anxiety when invited to a place where unfamiliar foods will be served. If mealtimes are a daily struggle, it may be a sign of something more, especially for people with autism.
Avoidant/restrictive food intake disorder (ARFID) is an eating disorder in which a person avoids certain foods, eats very little or becomes so anxious about eating that it begins to affect their health, growth or daily functioning.
If you or a loved one has autism and is struggling to eat because of food textures, smells, routines, or anxiety, you’re not alone. Find out what ARFID is and how it overlaps with autism.
How often do ARFID and autism overlap?
Here's what the research says:
ARFID and autism go hand in hand. The numbers show that the connection is real, common and often overlooked.
ARFID is not about body image
ARFID is different from eating disorders like anorexia nervosa. It is not about weight or shape. ARFID is rooted in:
Sensory discomfort
Low interest in eating
Fear or worry about eating
For many people with autism, food and mealtimes can feel unpredictable or overwhelming. Safe foods — foods that feel familiar and comfortable — often become part of a daily routine. Even small changes in texture, temperature, or brand can feel like a favorite show taking a sudden, unexpected twist.
Here’s what that might look like in real life: Tortellini is often considered a safe food for dinner. However, when it’s slightly undercooked and has a firmer texture, someone with ARFID might refuse to eat it.
Or maybe at lunch, you offer your child their favorite bagel. But this time it feels chewier. Maybe this batch is tougher, and suddenly it’s no longer a safe food. They drop it, turn away, or become anxious before taking another bite.
The 3 main types of ARFID
Here at Eating Recovery Center (ERC), we see ARFID show up in a few ways.
1. Sensory sensitivity
For many individuals with autism, eating is a big sensory experience. Certain sensations can feel “too much,” including:
Taste
Smell
Texture
Temperature
Color
Mouth feel
As a result, such individuals may avoid foods that are slimy, mushy, crunchy, gritty, sticky, or mixed together. These sensory sensitivities with autism can be uncomfortable and even feel harmful. These patterns are often described as autism food aversion or autism texture sensitivity.
2. Low interest in eating
Some individuals with autism spectrum disorders do not:
Look forward to eating
Enjoy food
Feel hungry
This is sometimes called low-appetite ARFID. And we know from experience that people who undereat or limit the foods they consume may encounter low energy, malnutrition, growth delays and weight loss.
Low interest in eating can stem from not liking the setting or timing of meals, becoming bored with familiar foods or feeling anxious about eating. Biological reasons can also play a factor. Some individuals may have difficulty noticing or interpreting internal cues of hunger and fullness, which can make it even harder to maintain regular eating patterns.
3. Fear of negative consequences
Fear and anxiety can also show up during mealtimes. People with autism and ARFID may avoid eating because they fear:
Choking
Vomiting
Stomach pain
Allergic reaction
Contamination or food poisoning
This fear can come from a past negative experience or have no clear cause.
ARFID, food aversion and “picky eating”
We often hear well-meant comments like “They’ll grow out of it” or “They’re just picky.” But ARFID is different.
Ovidio Bermudez, MD, senior medical advisor at ERC, explained on our Mental Note Podcast that most kids eventually try foods again after avoiding them.
However, children with ARFID don't often try new foods again because their fear or discomfort is much stronger.
Children with autism often have eating habits like:
Preferring bland or simple foods
Sticking to the same meals
Avoiding mixed textures
Getting upset when foods look or feel different
These can be early signs of something more than picky eating.
Picky eating isn’t always an eating disorder
Most picky eating starts around age one to three years and fades by early elementary. But ARFID stands out because it doesn’t go away. And ARFID:
Affects growth
Causes nutritional problems
Impacts daily life
Creates stress for families
Food refusal may look like stubbornness or avoidance on the outside, but inside it can feel like fear, overwhelm, or sensory overload.
All people with ARFID have restrictive eating, but not all restrictive eating is indicative of ARFID.
Why kids with autism struggle with food
Many parents search for “food for autism & picky eaters,” hoping to find solutions. But the challenging eating habits associated with autism often come from the way a person processes the world.
This includes:
Sensory sensitivity
Past food trauma
Co-occurring ADHD, anxiety, OCD, or other conditions
Strict routines
Trouble noticing hunger cues
Some children avoid new sensations. Others need things to feel predictable. This can lead to rigid eating habits or a short list of safe foods that they stick to.
A study highlighted four sensory styles that may contribute to ARFID in children with autism:[4]
Registration: Noticing sensory input
Sensitivity: Feeling sensory input more strongly
Avoiding: Pulling away from overwhelming sensations
Seeking: Looking for more sensory input
Children with autistic traits who were more sensitive or avoided sensory input (“sensitivity” and “avoiding”) were more likely to show ARFID-related behaviors such as extreme picky eating or low interest in food.
Those who had low awareness or sensory signals (“registration”) were actually less likely to show picky eating or poor appetite.
Eating challenges for teens with autism
Food challenges may get harder in the teen years. Teens with autism may struggle with:
Self-consciousness when eating around friends
Noisy, smelly cafeterias (sensory overload)
Trying new foods at social events
Pressure to “just try it”
Expectations to be more independent with meals
ARFID teen programs help families identify what is sensory-based, what is fear-based, and what is related to growing independence.
Adults, autism and ARFID
Some food challenges don’t fade with age. Many adults with ARFID have long-lasting autism food aversion. These may be tied to sensory overload, stress, routines, or anxiety.
Some cases are misdiagnosed as anorexia, but factors vary. Let’s compare.
Factor | ARFID | Anorexia |
Motivation | Avoidance based on fear or sensory discomfort | Avoidance based on weight or body image |
Common triggers | Texture sensitivity, choking fears, nausea fears, sensory overload | Fear of weight gain, desire for thinness, body dissatisfaction |
Body image concerns | Typically not present | Central to the disorder |
Adults with autism deserve support based on recognition of their needs and understanding of how sensory experiences, anxiety and routines shape eating.
Autism and the risk for eating disorders
People with autism can experience many kinds of eating challenges, including anorexia. This is because food is tied to sensory input, anxiety, routines and how the brain processes hunger and fullness. When these systems feel overwhelming or unpredictable, eating patterns can shift.
This can show up as:
Food refusal
Strong reliance on safe foods
Other autism-related eating disorder symptoms
These patterns aren’t caused by choice or stubbornness. They’re rooted in how the body and brain respond to the world. The most effective eating disorder treatment adapts to each person’s sensory, emotional, and developmental needs.
We treated ARFID before it had a name
ARFID wasn’t added to the Diagnostic and Statistical Manual of Mental Disorders until 2013. Many people lived with ARFID symptoms long before there was language for what they were experiencing.
ERC has been supporting individuals with these patterns for years — and continues to add new programs to meet the needs of autistic children, teens, and adults.
By introducing individuals to varied textures, smells, tastes and sensations (including the feeling of having a full stomach), we can help children, teens, and adults meet their daily nutrition requirements and decrease their anxiety around food.
