Autism and eating: beyond 'picky'

It is not fussiness

An autistic child who eats eight foods is not being difficult. Texture, smell, temperature, colour, the sound a food makes, whether foods touch on the plate, whether the packet changed: all of these can make a food impossible in a way that a neurotypical adult can barely imagine. Add anxiety about new things and a strong need for sameness, and a narrow diet is the predictable result.

What not to do

Do not make eating a battle. Pressure, bribes, "just one bite", and hiding foods inside other foods all tend to make the list shorter, not longer, because they add threat to a situation the child already finds threatening. A child who has learned that mealtimes are a fight will eat less, not more.

What tends to help

Keep the safe foods safe and always available. They are the foundation, not the enemy. Add new foods at a distance: on the table, not the plate. Then on the plate, not required. Then touched, smelled, licked, over weeks. Change one thing at a time: the same food in a slightly different shape before a different food. Let the child be involved in shopping and preparing, because familiarity lowers threat. Expect progress in months, not meals.

When to ask for help

If your child's weight or growth is a concern, if the diet has fewer than a handful of foods, if there is gagging or vomiting, or if you are worried about nutrition, speak to your GP and ask about a referral to a dietitian, and, for feeding difficulties, to speech and language or occupational therapy. Avoidant restrictive food intake disorder (ARFID) is a recognised condition that overlaps with autism and has its own support.
