glutamate

Interesting - the metafilter referenced elsewhere on the thread had a pointer to a paper about D-glutamate vs L-glutamate.

It was recently found that glutamate, a neurotransmitter actually is an activator in mesolimbc dopaminergic pathways.

Plants have glutamate receptors (analogous to higher organism's system for memory formation and learning).

There's some evidence that increased serotonin levels modulate glutamate after about 4 weeks, and glutamate antagonists like Ketamine are effective on depression more rapidly than serotonin agonists (as quick as 40m in some studies).

Some of the first evidence that glutamate additives were dangerous was provided by Dr.

Give a mouse, or a person, a high oral dose of MSG, and their plasma levels of glutamate are not significantly changed.

According to the CDC, common substances in vaccines include: Aluminum, Formaldehyde, Monosodium glutamate (MSG) and Thimerosal (a mercury-containing preservative).

It's present in various additives such as monosodium glutamate and hydrolyzed yeast extract.

Maybe due to better optimization / control for L-glutamate production in the bacteria?

Monosodium glutamate should be avoided if you care about your nervous system.

The abstract claims foods to which MSG is added directly contained lower amounts of D-glutamate than foods where the MSG comes from fermented foods.

The issue is that anyone would make a "no added glutamate" claim, thus perpetuating the myth that glutamate matters.

There are tons of products out there with "no added glutamate" that have yeast extract on their ingredient list.

Apparently, bacterial fermentation generates a fair amount of D-glutamate, but this is true of "naturally occurring" fermentation (such as in cheese) too.

There's an amino acid called glutamate which creates an umami or "meaty" flavor.

Glutamate seems to be getting more attention these days, in terms of its potential role in mental illness.

Glutamate is a fundamental building block of life.
