That means that eating dopamine-rich foods (I am not sure what you mean by this) is completely pointless as far as increasing the levels of dopamine in the brains of people with PD or any other people for that matter is concerned.

On the other hand, L-DOPA can be transported across the BBB and is then converted into dopamine in the brain - I tried to explain this to you above.

That is why L-DOPA is indicated for people who live with PD.

I hope that this clears things up for you - it is all basic biomedical science.
Kiwi I doubt if there is a food which contains dopamine. That was not what I meant. I am talking about the brain or rather the consciousness , knowing that you did something that helps humans survive, or at least did a million years ago, rewards us with releasing more dopamine, thus encouraging us to do that activity again.
