by A significant number of children experience autism and ARFID, or restrictive food intake disorder. Understanding the nuances of eating and behavioral issues is critical to effective support and interventions for affected children.
ARFID significantly affects children’s eating behavior and sensory profiles, and fear of new foods exacerbates dietary restrictions. When co-occurring with ASD, these challenges increase, requiring a thorough exploration of the relationship between these factors.

Autism Diet and Nutrition: How Does It Affect Autistic Health?
What is ARFID?
Eating behavior encompasses a wide spectrum of actions and attitudes related to food consumption. In children with ARFID, eating behavior is often characterized by extreme pickiness and aversion to certain textures, colors, tastes or smells. This choice often results in a limited and repetitive diet.
Picky eating is not uncommon, but in these cases, it can become overwhelming and restrict eating, leading to nutritional deficiencies and impaired growth.
It is essential to recognize that these eating tendencies are not just a matter of preference but may be rooted in sensory depth or challenges associated with autism.
Understanding the underlying causes of these atypical eating behaviors is critical to devising effective interventions.
The link between ARFID and autism
Behavioral issues related to eating are often noted in autistic children, especially those diagnosed with ARFID. Obsessions, extreme anxiety, food refusal, obsessive-compulsive tendencies, and mealtime rituals are common issues that can have a significant impact on a child’s overall well-being.
Preference for specific mealtime routines and fear of new foods may contribute to heightened anxiety for both the child and caregiver. These behavioral challenges often extend beyond the dinner table, affecting the child’s quality of life and placing a significant burden on caregivers.
Individuals with autism are more prone to ARFID due to several factors:
- Sensory sensitivity: Many people are more responsive to the textures, smells and tastes of food. This heightened reactivity can cause severe coughing on certain foods and a restricted diet.
- Routine and predictability: Autistic people may insist on eating the same foods consistently and resist trying new foods.
- Behavioral inflexibility: Many individuals with autism exhibit rigid patterns of thinking and behavior, making it difficult to accept changes in their diet or try unfamiliar foods.
- Communication challenges: Communication difficulties can make it difficult for individuals with autism to effectively communicate their food preferences or discomfort.
- Incidental concerns: High levels of anxiety, common in autism, can exacerbate fears and distractions related to eating.
Prevalence of ARFID in autism
Studies have shown a higher prevalence of ARFID in children with autism spectrum disorders compared to the general population.
The co-occurrence of autism spectrum disorders and ARFID can exacerbate the complex behavioral problems, creating a need for tailored interventions that address key features of autism spectrum disorders and the specific challenges posed by ARFID.
According to a 2023 study, 8.2-54.8% of children with ARFID were also diagnosed with an autism spectrum disorder.
ARFID and sensory processing
Sensory processing difficulties play a significant role in shaping the child’s relationship with food. Autistic children may have heightened sensitivities to different sensory stimuli, which affects the way they perceive and interact with different foods.
Texture is often distracting, and some children avoid specific textures, such as mushy or slimy foods, because of sensory discomfort. Others may seek intense sensory experiences, gravitating towards crunchy or spicy foods.
These sensory preferences and distractions can contribute to the selective eating patterns observed in autistic children.
Research suggests a bidirectional relationship between sensory processing issues and eating behaviors in autism. Sensory sensitivities may contribute to selective eating patterns, and restrictive diets may exacerbate sensory sensitivities.
Understanding the child’s sensory profile, preferences and distractions is essential to designing interventions that meet their sensory needs and foster a positive eating environment.
ARFID and autism treatment
Effective interventions for children with ARFID and autism spectrum disorders require a multidisciplinary approach.
Doctors, occupational therapists, speech-language therapists, psychologists, play therapists, and nutritionists collaborate to address the complex interplay of eating behaviors, behavioral problems, and sensory profiles.
Behavioral therapies, such as applied behavior analysis (ABA), can be beneficial in modifying eating behaviors and reducing mealtime stress. ABA reinforces positive behaviors and gradually expands the child’s acceptance of a wider range of foods.

Sensory interventions, such as sensory integration therapy, aim to enhance the child’s ability to process and tolerate sensory input, fostering a more positive eating experience.
These interventions focus on gradually exposing the child to different food textures, smells, colors 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 matters is essential to support the optimal growth and development of these children.
Many children with ARFID and autism need multivitamins and a multimineral supplement. It is recommended to collaborate with the doctor and a dietitian or nutritionist to ensure that the child’s dietary restrictions are addressed without affecting essential nutrients.
Nutritional supplements may be prescribed to address specific deficiencies. However, these supplements should be tailored to the child’s individual needs and closely monitored to prevent possible side effects.
It is essential to approach nutritional interventions sensitively, considering the child’s preferences and sensory challenges. Gradually introducing new foods and incorporating preferred foods with similar nutritional profiles can lead to a more balanced and varied diet.
Since selective eating often leads to nutritional deficiencies, planning a balanced diet and regular monitoring is essential.
Involvement of parents and carers
Parental and caregiver involvement is critical to implementing and sustaining interventions for children with ARFID and autism spectrum disorders. Education and support are critical to addressing the unique challenges presented by a child’s eating behavior and behavioral problems.
Parental involvement in therapy sessions, meal planning, and creating a positive eating environment at home can greatly contribute to a child’s progress.
ARFID and autism in adults
Adults with autism and ARFID may continue to have severe food disturbances and restricted diets due to sensory sensitivities and rigid eating patterns established during childhood. These challenges can lead to nutritional deficiencies, which affect overall health and quality of life.
Social situations involving food, such as eating out or attending social gatherings, can be very stressful and isolating for adults with both conditions.
Management of ARFID and autism in adults often involves a multidisciplinary approach, including nutritional counseling, behavioral therapy, and sensory integration strategies.
Unlike youth, adults may require more emphasis on self-advocacy and practical strategies for coping in social and work environments.
Ongoing 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 to developing targeted interventions.
Collaborative efforts between healthcare professionals, educators and caregivers are critical to creating a supportive environment. This would foster 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 challenges, and incorporating nutritional considerations are critical components of effective support strategies.
FAQs
Q: Is there a link between autism and food avoidance?
A: Yes, autism is often associated with food avoidance due to sensory sensitivities and rigid eating patterns commonly seen in individuals with autism.
Q: Is ARFID common in autism?
A: ARFID is relatively common in individuals with autism, as they are more prone to food avoidance and food behavior restrictions.
Q: Is ARFID a sensory disorder?
A: Although not considered a sensory disorder, ARFID is closely linked to sensory processing issues. Individuals with ARFID have an increased sensitivity to food texture, taste or smell, contributing to their food avoidance behaviors.
Q: At what age is ARFID most common?
A: ARFID is often diagnosed in childhood. However, it can continue into adolescence and adulthood and can be diagnosed at any age.
