Few topics generate as much advice for autism parents as food. Some of it is helpful. A lot of it promises more than the research can back up. Here is a grounded summary.
Feeding difficulties are common
Many autistic children eat a narrow range of foods, often chosen by texture, color or brand. Over time that can leave gaps in nutrients such as calcium, vitamin D and fiber. Stomach and bowel problems, constipation above all, are also more common, and a child who is uncomfortable will struggle more with sleep and behavior.
What the research says about special diets
Gluten-free and casein-free diets are the most widely tried. Reviews of the controlled studies have not found reliable benefits for autism itself, and cutting out food groups can make a narrow diet narrower. If you want to try one, do it with your pediatrician or a registered dietitian, and set a time limit for judging the result.
Omega-3 supplements have been tested in several small trials with mixed results. They are generally safe, and they are not a treatment for autism.
What reliably helps
- Treating constipation and reflux, which often improves mood and sleep
- Checking for nutrient gaps and filling them, with medical guidance
- Feeding therapy for children with very restricted diets
- Regular meals, enough water and a steady sleep schedule
How this fits with brain-based care
No particular diet is required for a qEEG brain map or for TMS, and no diet has been shown to make TMS work better. A child who is sleeping, eating and comfortable gets more out of every kind of therapy, which is reason enough to get the basics right.
Talk with your child’s doctor before starting supplements or removing foods. If you’d like to know about leucovorin, a prescription form of folate, we’ve written about that separately.
