Estradiol enhances glutamate toxicity. So does BPA. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2872694/
I researched this after having eaten a meal with a small amount of canned corn. Took about 10 minutes for extreme anxiety/msg reaction to form.

I usually stay away from corn, but it doesn't seem to bother me when I eat it, if I don't overdo it. But I always have frozen corn on hand.

This was Cadia organic corn. Their website is coy about whether they are BPA free. They say they encourage their manufacturers to provide BPA-free cans, and their Albacore tuna is BPA free. Thanks, that's really helpful.

Might also explain the seemingly nonstop MSG reaction I get from time to time, even if I haven't eaten anything. Though I think most people would call it bad PMS.

I also like the part that says Tamoxifan (among other drugs) prevented glutamate toxicity. Coincidence it's a cancer drug?

I wonder if progesterone is neuro-protective? I think I researched that once before, but can't remember -

There are studies that show estrogen is neuroprotective. This study explains that as women age and lose IGF-1 (insulin-like growth factor), the neuroprotective effects become toxic. And that estrogen itself can down-regulate IGF-1, if I read it correctly.
