Indeed. My main point was about the taste - since they are so similar, it would make sense that both glutamate and theanine are considered the major components of the umami taste. They don't seem to be the exclusive source of the taste, but then L-Theanine does make up something like 50%-60% of the amino acid content in tea so it probably wouldn't taste any different if those others weren't present.scruffmcgruff wrote:Yes, theanine and glutamate are very similar, structurally. However, so are GABA and glutamate, and it's hard to have more polar opposite functions in the brain than those two. What I'm trying to say is that minor differences in chemical structure can have enormous impacts on function. That said, it doesn't necessarily mean that they always *do*, so you may be on to something.
Tea has TyrosineIIRC, tyrosine is a dopamine precursor (it's what dopamine is made from), so it can help to restore proper dopamine levels in the brain. Where did the tyrosine thing come from, though?
I would really think that tea could help Tea contributes to overall well-being, which really only helps. I don't know a whole lot about depression, but I'm sure there are many different causes and I'd bet that tea could directly affect some of them. At any rate it's certainly not going to hurt, and if some of them can get on the road of discovery then I'm sure that path itself could helpkymidwife wrote:Good points about medications for depression, Silverneedle... especially for severe depression.
I've been a nurse practitioner for 11 years now, and I manage depression in women all the time, with and without medications. Antidepressant medication is a very serious matter, and that step in treatment is sometimes for the good and sometimes not. Knowing what I know about the risk profiles and side effects of these drugs, the potential for pseudo-addiction, the very real existence of drug withdrawal symptoms from some of them...
Well, lets just say, drugs are not the answer for everyone... especially for mild and possibly transient situational depression. It's very good to explore remedies provided by Mother Nature... sunshine, exercise, a healthy diet, etc. have all been shown effective in clinical research studies on depression. There's also some fairly significant research being done on the effects of essential fatty acid supplementation for depression, especially postpartum depression.
My query about tea is just to extend my own body of knowledge on how to recommend the healthiest diet and lifestyle for those in need. If they require medication, I'm willing to prescribe it, but I don't always jump to it as a first line of treatment. And really... if delicious tea helps too, I say lets drink more of it!
