Selective Eating in Autistic Children: Understanding and Supporting

🧠 Understanding the causes of selective eating

Selective eating in autism is multifactorial. Several causes, often combined, explain the restricted food repertoire of autistic children. Identifying the specific causes for each child is the first step towards effective support, as strategies differ depending on whether the selectivity is sensory, behavioral, or motor in origin.

Sensory causes are the most common. Oral tactile hypersensitivity makes certain textures unbearable: a child who refuses soft foods may have an exaggerated sensitivity to slimy textures, while one who refuses raw vegetables may be bothered by the crunchy texture that generates vibrations in the jaw. Gustatory hypersensitivity amplifies bitter or sour tastes, and olfactory hypersensitivity makes certain food smells nauseating.

📊 The different profiles of selectivity

Food selectivity manifests in very diverse ways depending on the children. Identifying your child's specific profile allows for targeting the most relevant strategies.

• Texture selectivity: the child only accepts a limited range of textures (all smooth, all crunchy, all dry). This is the most common profile, often linked to oral tactile hypersensitivity
• Color selectivity: the child refuses foods of a certain color (often green or red). This profile is linked to visual associations and cognitive rigidity
• Brand or presentation selectivity: the child only accepts a food in a specific packaging, a particular plate, or an identical presentation. The slightest variation leads to refusal
• Temperature selectivity: the child only eats cold or hot, refusing foods that are not at the expected temperature
• Compartmentalization selectivity: the child cannot tolerate foods touching on the plate, requiring compartmentalized plates

🍽️ Adapting the meal environment

Before working on expanding the food repertoire, it is essential to create a suitable and calm meal environment. A child who is in a state of sensory or emotional stress during the meal is not available to explore new foods. The priority is to make mealtime as comfortable as possible.

The sensory environment

The meal location should be calm, with appropriate lighting (no harsh neon), minimal background noise, and controlled smells. If the child is sensitive to cooking smells, airing out before the meal or preparing foods in advance can help. The physical setup should be comfortable: a chair at the right height, a footrest, and sufficient personal space at the table.

The structure of the meal

The meal routine should be predictable: same time, same place, same sequence (starter, main course, dessert, or any other organization that suits the family). The visual schedule can include the meal with a photo of the menu. A timer can indicate the duration of the meal to prevent it from dragging on indefinitely, which can lead to mutual frustration.

🌱 Gradually expanding the food repertoire

Expanding the food repertoire is a slow and gradual process that requires patience and consistency. Effective approaches rely on the principle of gradual exposure: familiarizing the child with new foods step by step, starting with tolerance of the food's presence and progressing to tasting and then eating.

The food chain

The food chain technique involves starting with an accepted food and introducing minimal and gradual variations. If the child eats white pasta, one can gradually change the shape of the pasta, then add a drop of sauce, then increase the amount of sauce, then vary the type of sauce. Each variation is so small that the child tolerates it, and the accumulation of small variations ultimately significantly expands the repertoire.

Sensorial exploration outside of meals

Food exploration activities outside of meals (cooking workshops, playing with foods, gardening) allow the child to become familiar with foods without the pressure of having to eat them. Touching a tomato during a cooking workshop, smelling herbs in the garden, or handling vegetables during a sensory sorting game are all steps that bring the child closer to acceptance, without stress or conflict.

⚖️ Ensuring nutritional balance

Nutritional concern is legitimate when the food repertoire is very limited. Regular medical follow-up is recommended to check growth, detect potential deficiencies, and, if necessary, prescribe appropriate dietary supplements.

At the same time, it is important to put things into perspective: a child who eats few foods but grows normally and is healthy is not necessarily in nutritional danger. Parental stress around food can be more harmful than the selectivity itself, as it creates an atmosphere of tension that exacerbates difficulties at the table.

🎮 COCO THINKS and COCO MOVES: developing flexibility

The COCO THINKS and COCO MOVES program from DYNSEO indirectly contributes to improving food selectivity by working on mental flexibility, a key cognitive function in accepting novelty. The COCO THINKS games that challenge flexibility and adaptation to rule changes develop a transferable skill that can generalize to other areas, including food.

👨‍⚕️ When to consult a specialist

If food selectivity is severe or if it does not improve despite the strategies implemented at home, it is relevant to consult specialists. The speech therapist specialized in oral disorders evaluates the oral motor and sensory aspects of eating and proposes appropriate rehabilitation. The occupational therapist specialized in sensory integration works on overall desensitization that can improve food tolerance. The dietitian or nutritionist evaluates the nutritional status and proposes solutions to optimize intake with the existing repertoire.
