Supporting Autistic People’s Unique Relationships with Food: Honoring Autonomy, Sensory Needs and Nourishment

Eating is a routine activity for most people, but for autistic individuals, it can be deeply tied to sensory experiences, autonomy and emotional well-being. Autistic people commonly face food-related challenges including sensory sensitivities, interoception differences and restricted diets.

‍

Rather than focusing on compliance or normalizing food habits, supporting autistic people means respecting their individual relationships with food, embracing sensory needs and upholding autonomy. At the same time, it is important to consider any physical health impacts of dietary differences and discuss these with your physician in order to make an informed decision about whether you want to consider changes in order to maintain your health or prevent future health problems. You should always involve a doctor or nutritionist in any plans to make significant dietary changes, and any tips provided below have not been reviewed by a physician and are not intended to serve as medical advice.

Autistic individuals can experience a range of co-occurring conditions that impact their relationship with food and eating:

‍

• Anxiety: Social settings or being observed while eating can increase anxiety and distress, leading some autistic individuals to prefer eating alone.
• Gastrointestinal problems: Autistic children and adults frequently report GI symptoms like reflux, constipation and diarrhea, which can further complicate dietary habits.
• Attention deficit hyperactivity disorder (ADHD): Planning meals, grocery shopping and following multi-step recipes require a lot of executive functioning. Barriers here can lead to skipped meals or reliance on convenience foods.
• Eating disorders: Autistic people—especially women and gender-diverse individuals—have high rates of eating disorders, such as anorexia. Avoidant and restrictive food intake disorder (ARFID) is another eating disorder common for autistic people. However, ARFID is not linked to concerns about body weight or shape. Causes can include sensory sensitivities, fear of choking or vomiting or a lack of interest in eating. It is important to note that ARFID, anorexia, and other eating disorders can significantly impact physical health. Due to the medical risks, you should always discuss with your physician any concerns about your health that may be related to your diet, such as any signs of significant weight loss or possible nutritional deficiencies, or limitations in daily functioning. The tips listed below are not intended to serve as medical advice and should not be used by those with diagnosable eating disorders in place of advice from their physician or without consulting their physician. Eating disorders should be treated by a multidisciplinary team that may include psychologists, psychiatrists, registered dietician nutritionists, and occupational therapists.

Understanding food-related co-occurring conditions is important in addressing them in a neurodiversity-affirming way.

Sensory sensitivities and food

What may look like picky eating is often a sensory safety mechanism. Many autistic people experience hypersensitivities to textures, smells, tastes, temperatures and appearances. These sensory features can lead to food aversions or highly specific food preferences.

‍

Sensory sensitivities may mean that autistic people have a narrower range of foods they’re willing to eat, and they may be reluctant to try new foods. Understanding the role of sensory sensitivities in food choice is important because choosing food that aligns with one’s sensory profile is a form of self-care, not defiance. 

‍

Here are some tips on sensory-friendly food choices:

‍

• Start with your favorites and then choose new foods with similar textures, colors or temperatures to foods you already enjoy.
• Choose foods with predictable textures, since many autistic people are sensitive to crunchiness, mushiness or mixed textures.
• Find your temperature comfort zone. Explore whether you prefer room temperature, hot or cold.
• Try foods with mild smells or simple appearances, since strong smells or bright colors might feel too intense.
• Having a routine for eating, such as eating in the same place with the same plate and utensils, can make the food feel more approachable. Ensure that mealtime is a calm time.
• Try low-stakes exposure by simply looking at a new food first before expecting to eat it.
• Make foods visually appealing by cutting them or arranging them in a pleasing way.
• Keep photos or a list of foods that made you feel good, and revisit them when you need something easy.

‍

Above all, listen to your body. If a food feels wrong, you’re not being picky—your sensory system is doing its job.

Autistic people may experience differences in bodily sensations, called interoception. Interoception is what helps you feel hunger, fullness or thirst. Differences in noticing these internal cues can result in undereating or overeating. 

‍

Here are some tips for supporting nutrition if you struggle with interoception:

‍

• Use visual reminders or timers to help you remember regular meals. Structured meal times can compensate for difficulties in recognizing hunger or satiety cues.
• Track mood and energy levels related to food intake. This can provide an indication of nutritional needs.
• Take regular hydration breaks. Since thirst can be harder for autistic people to recognize, it’s helpful to establish a routine that doesn’t rely on internal thirst cues.

‍

By understanding and accommodating differences in interoception, you can better meet your nutritional needs.

For many autistic individuals, "same foods" or “safe foods” are comforting staples that provide a sense of sensory predictability and emotional regulation. These foods can help reduce anxiety by offering consistency and familiarity. Embracing and respecting safe foods is essential for meeting your nutrition needs in a positive and stress-free way. 

‍

If you're concerned about getting enough nutrition, you might feel tempted to stop eating your same or safe foods, but this can be overwhelming. Instead, consider focusing on packing as much nutrition as possible into one meal each day—your nutrition-heavy meal—while making it as sensory-friendly as possible. Allow yourself to enjoy safe foods for the rest of the day, knowing that you’re still meeting your nutritional needs in a way that works for you.

‍

For some autistic individuals, eating can serve a self-regulatory purpose, functioning as a form of stimming. Certain foods, particularly those that are chewy or crunchy, provide proprioceptive input—deep pressure through the jaw—which can be calming and help manage sensory overload. This type of oral sensory input has been shown to have a legitimate place in autism support, with products like ARK Therapeutic’s chewable tools offering an effective and safe way to engage in this type of stimming.

‍

Destigmatizing mouth-based stimming is crucial for creating safer and more inclusive spaces. By acknowledging the role of food in self-regulation, we can reduce judgment and provide more supportive environments to accommodate diverse food and sensory needs.

Creating environments that respect diverse food needs is essential for fostering inclusion and support. Here are some strategies to help build food-inclusive spaces:

‍

• Create sensory-friendly dining spaces: Ensure that dining areas are comfortable for everyone by controlling lighting, reducing noise and providing seating options that are spaced apart.
• Use visual menus and simple ordering: Visual aids can help make food choices clearer. Also, providing clear and explicit ordering directions is important, as unstated or ambiguous instructions can create barriers for autistic people.
• Allow flexible mealtimes at school or work: Offering flexible meal schedules can accommodate different sensory or hunger needs, reducing stress.
• Simplify meal prep: Simplifying the food preparation process—such as by using pre-portioned foods, batch cooking or opting for delivery kits—can help make meals more manageable. This is especially helpful for individuals experiencing barriers related to executive functioning, as it reduces the planning and decision-making required to maintain a healthy diet. 

‍

Accessible food environments can make eating routines smoother for autistic individuals. For those who wish to seek greater support, neurodiversity-affirming professionals can provide even more support strategies.

Many professionals can support an autistic adult if they are facing barriers related to their food and nutrition. It’s important to work with dieticians, occupational therapists, and therapists who understand and respect neurodivergent needs. Approaches should emphasize collaboration, not correction, and ensure that an individual’s preferences and experiences are at the center of the process.

‍

Here are some red flags to avoid:

‍

• Food refusal labeled as “noncompliance”: Instead, it’s important to understand food refusal as a valid expression of sensory preferences or underlying factors.
• Withholding preferred foods as punishment: Using food as a means to control someone can harm that person’s relationship with food and other people, and it should be avoided.
• Shaming or pressuring someone to eat: Shaming individuals for their food choices can lead to anxiety and even more negative associations with food.

‍

Here are some green flags to look for:

‍

• Respecting food preferences and sensory needs: This involves acknowledging and honoring an individual’s food preferences or sensory sensitivities without judgment or pressure.
• Encouraging empowerment and autonomy: This looks like professionals supporting individuals in making their own food choices.
• Offering positive and non-coercive guidance: This involves approaching food challenges with patience, understanding and collaboration rather than correction.

‍

Eating doesn’t need to look a certain way to be valid. Autistic individuals should have comfort, autonomy and nourishment in their food relationships by affirming their whole selves and fostering a positive and empowering approach to food.

Autism is often associated with gastrointestinal issues and, at times, nutrition concerns. As a result, dietary approaches have been used as “treatments” for autism. However, these diet trends targeting autism can often be overly restrictive and even harmful without a medical diagnosis.

‍

Many dietary interventions, such as the gluten-free and casein-free (CFCF) diets, have been widely discussed in relation to autism. However, despite the popularity of such diets among caregivers, there’s insufficient evidence to support any benefits. Until there is such evidence, experts caution against restrictive diets for autistic people unless someone has a medically diagnosed allergy or intolerance.

‍

Empowering personal choice fosters autonomy and helps reduce anxiety around meals. While it’s true that eating better can improve overall well-being, it’s essential to focus on nourishment in a way that honors neurodiversity. Autistic people may also have unique food preferences or eating habits, which should be respected—not corrected.
