Autistic people are often picky eaters due to intense sensory sensitivities (texture, smell, taste), strong preference for routine and predictability, anxiety around new foods, and potential underlying gastrointestinal or motor issues, making food a challenging and overwhelming experience rather than just a nutritional one. This selectivity is rooted in differences in sensory processing, a need for control, and difficulty interpreting internal hunger cues (interoception), leading them to prefer consistent, manageable foods like crunchy chips or smooth purees.
Autism often goes hand in hand with food aversions; an expert provides strategies for gently expanding a narrow diet. If you have a picky eater with autism, know that you're not alone.
Furthermore, individuals with Autism generally succumb to health complications approximately 15 to 20 years earlier than the general population. Longitudinal studies that followed people with Autism for over 20 years found that the average life expectancy ranges between 39 years and 58 years.
Around 90% of autism cases are attributed to genetic factors, meaning autism is highly heritable, with many different genes contributing, rather than a single cause, often interacting with environmental influences during early brain development, though specific environmental factors don't cause it but can increase risk. Twin studies show strong genetic links, with concordance rates between 60-90% in identical twins, and research points to complex interactions of many genes and prenatal/perinatal factors.
This study suggested that food selectivity is not a unique characteristic of autism per se, but may reflect sensory defensiveness. It has been suggested that sensory sensitivity may lead children with ASDs to restrict their intake to food of preferred, tolerable, and manageable textures (1, 3, 12, 17, 20).
The "6-second rule" for autism is a communication strategy where a speaker pauses for about six seconds after asking a question or giving information, giving the autistic person extra time to process it without feeling rushed, which helps reduce anxiety and allows for a more thoughtful response, reducing frustration for both parties. Instead of repeating or rephrasing, which can be confusing, you wait, and if needed, repeat the exact same words after the pause.
Chinning is a form of repetitive self-stimulatory behavior (stimming) that you may notice in children or adults with autism. It involves pressing, rubbing, or holding the chin against objects, surfaces, or even hands to gain sensory input or comfort.
Additionally, inherited genetic variations contribute greatly. Research shows that both mothers and fathers can carry autism-related gene variants. Some of these are common variants that increase the risk of autism, while others are rare mutations causing more severe effects.
Understanding the 6 stages of an autism meltdown can help parents, caregivers, and educators respond with empathy and support.
Changes in the diagnostic criteria and increased screening at wellness visits seem to be the main contributors.
In general, people who have an active lifestyle are much more emotionally resilient and focused. There also seems to be some evidence that physical exercise helps people with depression and ADHD, which are commonly co-occurring conditions with autism.
Autistic individuals often experience and express love and connection in ways that can differ from neurotypical expectations. Communication for autistic people in relationships tends to be direct and literal; understanding nonverbal cues can sometimes be a challenge.
What NOT to Say to Someone with Autism
For example, a good diet for autism will be rich in fruits, vegetables, and lean proteins to improve gut health and reduce inflammation, which has been linked to improved behavior and cognition in autistic individuals.
Symptoms of High-Functioning Autism
Difficulty with Social Interaction: Individuals with high-functioning autism may struggle to understand social norms, make eye contact, initiate or maintain conversations, and interpret nonverbal cues such as facial expressions or body language.
Some research suggests between 4% to 23% of people with an eating disorder are also autistic. Some research suggests anorexia is the most common eating disorder amongst autistic people.
Yelling at an autistic child can cause confusion, fear, and emotional distress that may last far longer than you'd expect. Because autistic kids often process language, tone, and emotions differently, loud voices can be overwhelming—sometimes even physically painful.
Meltdowns can be expressed verbally (eg, shouting, growling, or crying), physically (eg, kicking or flapping) or a mixture of both ways. An autistic person will lose control of their behaviour because they are completely overwhelmed and are unable to express themselves another way.
However, autistic meltdowns are not age-related and they may happen at any age. Many autistic adults, especially the higher functioning ones, may learn some strategies to prevent meltdowns and cope with them.
Researchers are not sure what causes autism, but they believe genetic and environmental factors play a role. Risk factors can include having older parents or a sibling with ASD, genetic or chromosomal conditions like Down syndrome or fragile X syndrome, and very low birth weight.
Signs of autism in adults
Because autism spectrum disorder can't be cured, many parents seek alternative or complementary therapies. But there's little or no research on these therapies to show whether they're helpful. And some alternative treatments could be dangerous.
Babies with Autism Do Smile – Just Not Always How You Would Expect. A common misconception about autism is that babies with autism don't smile. They do — but their smiles may appear less frequently, come at unexpected moments, or not seem directly tied to social interaction.
Common Obsessions in Autism
One concept that has gained increasing attention is Cassandra Syndrome-a situation where one partner (often the neurotypical) feels unheard, unseen, or invalidated, especially when their struggles in the relationship are minimized or dismissed.
