Autistic adults tend to prefer eating alone, which may result in further social isolation. This study aims to understand contexts of challenges autistic adults face when eating with other people outside home.
Sensory issues with food: Kids on the autism spectrum often express a strong preference for foods that feel a certain way in their mouths. Some prefer soft or creamy foods like yogurt, soup or ice cream; others need the stimulation that crunchy foods like Cheetos or — if a parent is lucky, carrots — provide.
Such food behaviours can include very limited food preferences, hypersensitivity to food textures or temperatures, and pocketing food without swallowing. A diet could be primarily made up of pasta, bread and chicken nuggets with little desire to try new foods and different textures.
Eating problems are common in autistic people.
Issues such as only eating very few foods, not being able to eat at school, going long periods of time without eating and pica (eating non-foods) can feel difficult to understand and manage.
Children on the autism spectrum are more likely to have a restricted diet, refusing more foods and eating a more limited food repertoire than their typically developing peers [4–6].
Some autistic children might graze all day, and some might eat too much at meals. If your child has overeating habits, it's good to work out why. This can help you manage your child's eating behaviour. Some children eat more because their medicine increases their appetite.
Many autistic people struggle with interoception. This means that they have a difficult time feeling and interpreting their body's signals. This connects with disordered eating behavior because it means they may miss their body's cues that they are hungry or full.
Kids with autism can be extremely selective when it comes to eating. An estimated 46–89% of children with autism spectrum disorder (ASD) have feeding problems. ASD children struggle with sensory defensiveness, a need for routine and sameness, and visual overstimulation which makes expanding the palate difficult.
Sensory issues: Children with autism often have strong preferences for certain textures and temperatures. Some kids prefer soft, creamy foods like purees or even baby food. Others need the extra stimulation of crunchy foods. In every case, sensory preferences can limit what kids are willing to eat.
Signs of High-Functioning Autism in Children
May appear more mature for their age and have above-average intelligence. A tendency to avoid eye contact. Trouble deviating from a routine or adapting to changes. Trouble making friends and maintaining social relationships or not “fitting in” with peers.
Food can be one of life's great comforts. As you point out, eating to self-soothe or for sensory stimulation may be particularly common among those with autism. One contributor may be the stress and anxiety that often accompanies autism spectrum disorder (ASD).
It's not uncommon for individuals with ADHD and autism to prefer to eat the same food—multiple times a day sometimes—for extended periods.
Many autistic people have intense and highly-focused interests, often from a fairly young age. These can change over time or be lifelong. It can be art, music, gardening, animals, postcodes or numbers. For many younger children it's Thomas the Tank Engine, dinosaurs or particular cartoon characters.
Autistic people can often have trouble sleeping. There are a range of reasons for this including difficulties with relaxing or winding down and irregular melatonin levels. Problems with sleep can be an issue for both autistic adults and children.
Many autistic people experience hypersensitivity to bright lights or certain light wavelengths (e.g., LED or fluorescent lights). Certain sounds, smells, textures and tastes can also be overwhelming. This can result in sensory avoidance – trying to get away from stimuli that most people can easily tune out.
Children with autism are often clumsy, physically awkward or uncoordinated.
While cognitive empathy can be lower in people with autism, affective empathy—which is based on instincts and involuntary responses to the emotions of others—can be strong and overwhelming. In fact, newer research suggests that some people with autism may actually feel other people's emotions more intensely.
Many kids with autism also have postural issues that interfere with eating. Low muscle tone, for example, can make it difficult to maintain an upright seated position. Autism-related sensory aversions are another common reason for eating problems.
Autism Cooking
Autism can affect cooking in several ways, including sensory sensitivities, motor challenges, and picky eating habits. However, with the right support and strategies, individuals with autism can develop their cooking skills and enjoy preparing meals.
Of course, autistic individuals laugh when they are happy, or if they find something funny. However, they often laugh to release fear, tension and anxiety. What is very difficult for their parents to comprehend (and accept) is that they might laugh or giggle non-stop when someone is crying.
People with autism may get easily attached to people, leading them to become over-friendly. It can be difficult to understand other people's perceptions of situations, therefore what they feel is appropriate, may be considered as socially unacceptable.
Being autistic can make fatigue and burnout more likely, due to the pressures of social situations and sensory overload.
Many adults on the spectrum struggle with food and cooking because of sensory stimuli, extreme sensitivity to change, and a strong preference for a narrow selection of ingredients. Research shows that individuals with autism tend to favor processed foods and carbohydrates.
