When I think "glutamate" I have to take care not to ingest any, but ALSO to take care not to ingest anything that actually boosts the amount of glutamate ingested.
Celery, parsnips, fig skin together with citrus fruit skin, and some whole citrus fruit (bergamot, pomelo, bitter orange) do exactly that.
Celery and those others contain psoralens also called furocoumarins. Those are inhibitory of cytochrome P450 3A4 and inhibitors of glutamate dehydrogenase. Not at all a good idea for us.
Celery to fight excitotoxicity? Certainly not for me.
This is why they make celery salt, which is just as addictive as MSG.
Dundee marmalade is also highly addictive. So are pickled lemons used in North African cooking to give more "taste" in stews. Highly addictive too.
If you drink ready-made orange juice for breakfast, remember it is made including the skin. You are most probably addicted to it.
The effect of a small dose of furocoumarins lasts for 3 days. The time it takes for regeneration of the intestinal cells containing the P450 as it follows a "suicide" reaction. No wonder we are exhausted.
I face the fact that I am addicted, that my body craves for that drug. And that if I avoid all glutamates religiously, it will look for ways to boost my intake. The price of this addiction is terribly high. Once you know about it, you can change your life.
Be well!!!
