Have you heard about the ADHD diet?

I am not aware of any "adult testing" but in response to your personal observations - I would suggest that if motivated,  you could try removing typical "instigators" like full sugar sodas, foods processed with alot of sugar, preservatives and colorings and also the foods you personally suspect as being agents of "mood swings."  It can be challenging, but if some of your issues are caused by foods, it would be really helpful and even healing to find the ones that might be giving you some challenge.

In order to really find the "problematic foods' you need to remove them and be off them for a period of time and then re-introduce them one by one and see if you can find some common  ingredients.

HI THERE,

I DON'T KNOW ABOUT SPECIFICS BUT WITH MY ADD/ADHD MY DIET & MOODS ARE BEST IN A DIET SIMILAR TO THE SOUTH BEACH ASPECT OF EATING.....LOTS OF GREEN & COLORFUL VEGGIES....FISH  MEATS CHIX. PORK  ETC.. PLUS SUPPLEMENTS RICH IN THE B VITAMINS.  IT JUST MAKES MY THINKING SEEM CLEARER AND I FEEL LESS DISTRACTED TOO!!

I am sure many people with ADD/ADHD have some success finding the personalized eating plan that works for them though there are probably some shared features that work for many (like watching processed sugars and food colorings/preservatives).  That's great that this particular eating plan helps you.
