I was reading somewhere that it's not actually glutamate that causes the problem with DP. Having high glutamate in and of itself is not an issue. The issue is calcium ions. Glutamate neurotransmitters act as a gateway allowing certain molecules into the neurons. When you have too much glutamate the pathway is held open allowing too much calcium and other elements to flood the cell. This results in excitotoxicity and cell-death.
My question is that if DP is a result of high glutamate would eating things like dairy and cheese be dangerous? I know this might sound silly I'm just worrying if this could cause permanent brain damage if you have too much calcium. As DP can be caused by irregular calcium channels.
