Earlier quoted context omitted.

The hypothesis was that IgG tests may pinpoint foods that in some way trigger ADHD symptoms. This was found to be incorrect. "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." [1] To me, this says tha…

Thank you so much for the correction. I had somehow read only the part about the sequence of food reintroduction having no association but missed the conclusion from that, which now of course seems obvious. That really is something different. I'm surprised that this lede was buried in the articles on this result I've read. So the mystery continues. Very curious.

That conclusion was really buried in there. Some form of confirmation bias on the part of a reader, perhaps?

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…

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.

Is this relevant to Hacker News because a significant portion of us are ADD and need to cut out the bahama mamas from our drink diet?

We've gotten to the point where damn near any article is argued to be relevant to Hacker News. Keep fighting the good fight... I'm with you in spirit.
