A recent AJ Psychiatry reported a meta review of studies of non pharmacological interventions for ADD or ADHD in children. I was surprised that elimination of artificial food coloring showed a small positive effect. This was thought to be limited to a small group of children who had food sensitivities, and maybe to non FDA approved colorings.
I was less surprised that omega 3 fatty acid (and the like) showed some small benefit.
There was no support for other food restriction approaches.
There were some problems with the overall study and the results it reported, but it’s good that these things are being researched..
I hope to post some additional scientific results soon.
