Eating habits can be deeply personal, shaped by culture, upbringing, personal preferences, and sensory experiences. For adults with autism, eating habits often reflect a complex relationship between sensory issues, routine-based behaviors, food issues, and even social challenges.
While some autistic adults may have diets that look typical, many experience unique struggles and preferences that influence their relationship with food. Creating a diet chart tailored to individual sensory needs and nutritional requirements can be a helpful way to establish a balanced and comfortable eating routine.
Sensory Sensitivities and Food Preferences
One of the most significant factors that affect the eating habits of autistic adults is sensory sensitivity. Food is a multi-sensory experience that engages taste, texture, smell, and even sound. Many autistic individuals have heightened or reduced sensitivity in one or more of these areas, which can make certain foods highly appealing or completely unbearable.
Strong flavors such as spicy, bitter, or overly sweet foods may be overwhelming for those with heightened taste sensitivity. They may prefer bland foods, mild seasonings, or simple flavors that don’t overpower the senses.
On the other hand, some autistic adults seek out bold and intense flavors, enjoying sour, spicy, or heavily seasoned foods because they provide a stimulating sensory experience.
Texture is another major factor. Many autistic adults prefer foods with consistent and predictable textures. Crunchy foods, for example, might be preferred because they provide clear feedback when bitten.
Others may struggle with foods with mixed textures, such as fruit yogurt with chunks because the unpredictable sensation can be distressing. Some may avoid mushy, slimy, or sticky textures, which means foods like mashed potatoes, pudding, or certain meats may be off-limits.
The smell can also influence food choices. Some autistic adults may have smell sensitivity to food odors, making certain meals unbearable simply because of their scent. Even the smell of cooking food can be overwhelming. This can make it difficult to eat in certain environments, such as restaurants or cafeterias, where a variety of food smells mix together.
Routine-Based Eating and Food Preferences
Routine plays a huge role in how many autistic adults approach food. For some, eating the same meals every day or sticking to a set schedule provides a sense of comfort and predictability.
Changes in diet or eating patterns can be stressful, leading to anxiety or even a refusal to eat unfamiliar foods.
Some autistic adults develop a preference for specific brands or even packaging. A slight change in the look or feel of a familiar product can make it difficult for them to eat the same food they previously enjoyed. This is why some individuals will only eat a certain brand of chicken nuggets, a particular type of cereal, or a specific brand of yogurt. The consistency of these products offers reassurance that nothing has changed.
Others may eat in a highly structured way, following strict routines about when, where, and how they eat. Some might insist on using the same plate, the same utensils, or eating meals in a particular order. If their routine is disrupted, they may struggle to eat at all.
Selective Eating and Food Aversions
Selective eating is common in autistic individuals, with some having very limited diets. While picky eating is a common phase for many children, autistic adults who experience selective eating often continue these habits into adulthood. The reasons can be complex, ranging from sensory challenges to anxiety around unfamiliar foods.
Some individuals eat only a small number of foods and struggle to expand their diet. For example, they may eat only beige foods like bread, pasta, and chicken, avoiding anything with strong colors or unusual textures.
Others may have a preference for very simple foods, such as plain rice, cheese, or crackers because they are easy to predict in terms of taste and texture.
Trying new foods can be particularly difficult. Many autistic adults experience food neophobia or a fear of new foods. They may feel anxious about unfamiliar dishes, unsure of how they will taste or feel.
Some may need multiple exposures to a food before they feel comfortable trying it, while others may completely refuse to try anything outside their usual diet.
Emotional and Psychological Aspects of Eating
Beyond sensory and routine-based preferences, emotional and psychological factors also play a role in eating habits. Many autistic adults experience heightened anxiety, and this can affect their appetite and willingness to eat. Stressful situations, major life changes, or overwhelming social interactions may lead to a loss of appetite or an increased reliance on “safe foods” for comfort.
For some, eating can become a coping mechanism. Just as some people turn to comfort foods during stressful times, autistic adults may rely on their preferred foods to feel grounded. Eating familiar foods can provide relief from anxiety, creating a sense of control in an otherwise unpredictable world.
Social expectations around eating can also be challenging. Many meals involve social interactions, whether it’s eating out with friends, attending family gatherings, or participating in workplace lunches.
Autistic adults who struggle with social communication may find these situations stressful, leading to difficulties in eating around others. Some may avoid eating in public altogether, preferring to eat alone where they feel comfortable.
Strategies for Supporting Healthy Eating Habits
Although eating habits can be deeply ingrained, there are ways to support autistic adults in maintaining a healthy and balanced diet. Here are some of them:
