So they basically hypothesized ADHD is often a symptom of a food allergy, tested that premise and found some strong evidence for it. Just the kind of straightforward and useful study that somehow never seems to get funding.

Have a glance at the charts in the Lancet PDF (that erikpukinskis helpfully linked) to see the improvements versus the control group and the way that reintroducing high-sensitivity foods caused a regression:

Wow. If I was a NYTimes health reporter, I would start researching a story on how up-and-coming young families are requesting food allergy tests for their seemingly asymptomatic kids as a matter of course, because that's clearly going to be the trend now.

On page 500, under Discussion: "Blood tests assessing IgG levels against foods did not predict which foods might have a deleterious behavioural effect. ... We recorded no difference in behavioural effects after challenge with high-IgG or low-IgG foods. These results suggest that use of IgG blood tests to identify which foods are triggering ADHD is not advisable. However, IgG blood tests might be useful in other diseases."

I wonder if the IgG test they used is that reliable, though.

It might be that their results are limited by the accuracy of the ImuPro test, which would be a shame.
