A significant number of children experience autism and ARFID, or avoidant restrictive food intake disorder. Understanding the nuances of eating and behavioral problems is crucial to effective support and interventions for affected children.
ARFID has a significant impact on children’s eating behaviors and sensory profiles, with fear of new foods exacerbating dietary restrictions. When coupled with ASD, these challenges are exacerbated, necessitating a thorough exploration of the relationship between these factors.

Autism diet and nutrition: how do they affect the health of people with autism?
What is ARFID?
Eating behavior encompasses a broad spectrum of actions and attitudes related to food consumption. In children with ARFID, eating behavior is often characterized by extreme selectivity and aversion to certain textures, colors, tastes, or odors. This selectivity often results in a restricted and repetitive diet.
Difficulty eating is not uncommon, but in these cases it can escalate to severe aversion and restricted eating, which can lead to nutritional deficiencies and stunted growth.
It is important to realize that these eating tendencies are not simply a matter of preference, but may also be rooted in deep sensory sensitivities or challenges related to autism.
Understanding the underlying causes of these atypical eating behaviors is essential for developing effective interventions.
The Link Between ARFID and Autism
Behavioral problems related to eating are often observed in autistic children, especially those diagnosed with ARFID. Meltdowns, severe anxiety, food refusal, obsessive-compulsive tendencies, and eating rituals are common problems that can have a significant impact on the child’s overall well-being.
Preference for specific mealtime routines and fear of new foods can contribute to increased anxiety for both the child and caregiver. These behavioral challenges often extend beyond the dinner table, impacting the child’s quality of life and placing a significant burden on caregivers.
People with autism are more susceptible to ARFID due to several factors:
- Sensory sensitivities: Many people are more reactive to the textures, smells and tastes of food. This increased reactivity can lead to strong aversions to certain foods and a restricted diet.
- Routine and predictability: People with autism often want to eat the same things and have difficulty trying new things.
- Behavioral rigidity: Many people with autism exhibit rigid thought and behavior patterns that make it difficult to accept changes in their diet or try unfamiliar foods.
- Communication challenges:Difficulty communicating can make it difficult for people with autism to express their food preferences or discomforts effectively.
- Simultaneous fear: High levels of anxiety, which are common in autism, can worsen fear and aversion to food.
The prevalence of ARFID in autism
Research has shown that ARFID is more common in children with autism spectrum disorders than in the general population.
The co-occurrence of autism spectrum disorders and ARFID can exacerbate complex behavioral problems, creating a need for tailored interventions that address the core features of autism spectrum disorders and the specific challenges presented by ARFID.
According to a 2023 study, 8.2–54.8% of children with ARFID were also diagnosed with autism spectrum disorder.
ARFID and sensory processing
Sensory processing issues play a significant role in shaping a child’s relationship with food. Autistic children may experience heightened sensitivity to different sensory stimuli, which affects how they perceive and interact with different types of food.
Texture aversions are common, with some children avoiding specific textures, such as mushy or slimy foods, due to sensory discomfort. Others seek out intense sensory experiences and gravitate toward crunchy or spicy foods.
These sensory preferences and aversions may contribute to the selective eating patterns seen in autistic children.
Research suggests a bidirectional relationship between sensory processing deficits and eating behaviors in autism. Sensory sensitivities may contribute to selective eating patterns, while restrictive diets may exacerbate sensory sensitivities.
Understanding the child’s sensory profile, likes and dislikes is crucial to designing interventions that meet his or her sensory needs and promote a positive eating environment.
ARFID and autism treatment
Effective interventions for children with ARFID and autism spectrum disorders require a multidisciplinary approach.
Physicians, occupational therapists, speech therapists, psychologists, play therapists and nutritionists work together to address the complex interplay between eating behaviors, behavioral problems and sensory profiles.
Behavioral therapies, such as applied behavior analysis (ABA), can be helpful in modifying eating behavior and reducing stress during mealtimes. ABA reinforces positive behavior and gradually increases the child’s acceptance of a wider variety of foods.

Interventions that focus on sensory stimulation, such as sensory integration therapy, aim to improve the child’s ability to process and tolerate sensory input, which promotes a more positive eating experience.
These interventions aim to gradually expose the child to different food textures, smells, colours and tastes in a controlled and supportive environment.
Nutritional Considerations
The restricted and selective diets often observed in autistic children with ARFID raise concerns about nutritional deficiencies. Careful attention to nutritional considerations is paramount to support optimal growth and development of these children.
Many children with ARFID and autism require multivitamin and multimineral supplements. Working with the physician and a dietitian or nutritionist is recommended to ensure that the child’s dietary restrictions are addressed without compromising essential nutrients.
Nutritional supplements may be prescribed to address specific deficiencies. However, these supplements should be tailored to the individual needs of the child and closely monitored to avoid potential side effects.
It is essential to approach nutritional interventions with sensitivity, taking into account the child’s preferences and sensory challenges. Gradual exposure to new foods and the inclusion of favorite foods with similar nutritional profiles can contribute to a more balanced and varied diet.
Because selective eating often leads to nutritional deficiencies, a carefully planned and balanced diet with regular monitoring is essential.
Parent and caregiver involvement
Parent and caregiver involvement is critical in implementing and sustaining interventions for children with ARFID and autism spectrum disorders. Education and support are essential to overcome the unique challenges presented by the child’s eating and behavioral problems.
Parental involvement in therapy sessions, meal planning, and creating a positive eating environment at home can make a significant contribution to a child’s progress.
ARFID and autism in adults
Adults with autism and ARFID may continue to have severe food aversions and restricted diets due to sensory sensitivities and rigid eating patterns established in childhood. These challenges can lead to nutritional deficiencies, which impact overall health and quality of life.
Social situations involving food, such as dining out or attending social gatherings, can also be particularly stressful and isolating for adults with these two conditions.
Treatment of ARFID and autism in adults often requires a multidisciplinary approach, including nutritional counseling, behavioral therapy, and sensory integration strategies.
Unlike childhood, adults may need more emphasis on self-advocacy and practical strategies to navigate social and work environments.
Continued research for better understanding and support
Understanding the eating behaviors, behavioral problems, and sensory profiles of children with ARFID and autism spectrum disorders is critical for the development of targeted interventions.
Collaboration between healthcare professionals, teachers and caregivers is essential to create a supportive environment. This would promote positive eating experiences and promote the overall well-being of these children, while taking into account their unique needs.
Recognizing the role of sensory processing differences, addressing behavioral problems, and incorporating nutritional advice are essential components of effective support strategies.
Frequently Asked Questions
