You really got me going there for a few seconds, kudos (still waking up), but I don't think that's how the dopamine deficiency functions 🤣

Adhd'ers have less ability to create (or retain), dopamine. It's due to having less dopamine receptors, and they don't have the same level of efficiency to store it either, based off of some research that I did on the subject.

Edit: having said this, what we eat does totally play a part in helping our brain to produce the most "ingredients" for our brain to create it.
