Yes, picky and selective eating is actually a quite common concern for children with autism. If you rolled your eyes looking at the steps above because your child with autism has never had a full day's serving of vegetables in their life, you are definitely not alone. As if getting kids to eat their veggies isn’t challenging enough, research shows children with autism have significantly more eating challenges than their peers who are not autistic.
In addition to sensory difficulties that can lead to a lot of anxiety with food, autistic children are 4x more likely to have gastrointestinal issues such as stomach pain and discomfort. This creates the perfect storm for extra extra picky eaters - and a lot of added obstacles and concerns for parents.
The difficulties associated with autistic children and food can cause a wide range of concerns from children being underweight to overweight (overweight children can still be at risk for nutritional deficiencies!). This can lead to slower than normal growth and nutritional deficiencies like low vitamin D and calcium levels. Even when given multivitamins, many children with autism are still found to have some of these nutritional deficiencies.
