This study by Drs. Millichamp and Yee provides further evidence for the importance of proper diet for ADHD sufferers. (Unfortunately, the full text is not online)
From the abstract:
The recent increase of interest in this form of therapy for ADHD, and especially in the use of omega supplements, significance of iron deficiency, and the avoidance of the "Western pattern" diet, make the discussion timely.
Diets to reduce symptoms associated with ADHD include sugar-restricted, additive/preservative-free, oligoantigenic/elimination, and fatty acid supplements. Omega-3 supplement is the latest dietary treatment with positive reports of efficacy, and interest in the additive-free diet of the 1970s is occasionally revived. A provocative report draws attention to the ADHD-associated "Western-style" diet, high in fat and refined sugars, and the ADHD-free "healthy" diet, containing fiber, folate, and omega-3 fatty acids.
As I've learned about ADHD over the years, one thing continues to stand out.
The factors that help us focus are the same as the factors that help others focus.
This similarity can confuse ADHD skeptics. After all, they ask: wouldn't a crappy diet affect anybody's ability to focus?
The difference is: for us, the stakes are often higher. For us it can be the difference between a productive day and a day when we're unable to focus on anything at all.
