Can Food Aversions Point to Autism? 

Yes, food aversions in autism are common and can often be an early red flag. Many children with autism experience heightened sensitivities to textures, tastes, or smells, leading to strong dislikes certain foods. These sensory issues can make mealtimes challenging, as the child may refuse to eat specific foods or have a limited range of foods they are willing to try. 

In addition to food aversions in autism, picky eating is often observed. This is not just a preference, but rather a reaction to sensory sensitivities. For instance, a child may refuse foods with certain textures or smells, or they may become upset when foods are mixed together. This aversion to particular foods can be linked to the child’s need for predictability and control in their environment. 

How Food Aversions in Autism Manifest 

Common ways children with autism show food-related sensitivities: 

Texture Sensitivity:

Children with autism may avoid foods that feel too soft, hard, or lumpy. For example, they may refuse to eat mashed potatoes or foods with mixed textures like casseroles. 

Strong Reactions to Smell or Taste:

Certain smells or tastes may be unbearable to a child with autism, leading them to refuse entire food groups, such as fruits, vegetables, or meats. 

Limited Food Choices:

Picky eating can often be linked to a preference for specific foods, with the child refusing anything outside their comfort zone. 

Food aversions can be an autism red flag, particularly when they are accompanied by other signs of sensory sensitivities. Recognising this early can help parents and caregivers implement strategies to support the child’s needs.
