> The control solution was 100 ml of cool potable water and the L-theanine solution was prepared by dissolving 0.5 mg powdered L-theanine (Taiyo Kaguka Co. Ltd., Yokkaichi, Japan) per Kg participant body weight in a tea infusion (total L-theanine 50mg/serving).
So, there was a statistically significant difference in brain activity between participants who drank cool water and participants who drank (hot?) tea with added L-theanine. Curious setting.
- amluto 8y agoI find drinking a good cup of tea or other tea-like infusions to be quite relaxing. More so if I get to step it myself. I suspect that there’s a meaningful non-chemical effect, and this study has no ability whatsoever to discern whether L-theanine is involved.
- staunch 8y agoTry drinking just the hot water by itself. It's surprising and amusing how much of the effect you get. Pretty sure it was a Paul Graham tweet that pointed this out to me.
- colechristensen 8y agoHot water with lemon, morning or night, is excellent.
- ythn 8y agoWith a touch of honey
- vorpalhex 8y agoThere is a Russian beverage made by adding a ton of good quality honey to hot boiling water that is supposed to be an excellent cold remedy. No idea if it actually does anything, but it is delicious and soothing.
- Zelphyr 8y agoI think honey is supposed to have natural antibiotic properties. But also be careful about using too much of a ton of honey. Apparently the body will naturally purge an excess of honey ingested at once.
- n4r9 8y ago> Apparently the body will naturally purge an excess of honey ingested at once. That's a new one on me. Where did you hear that? What do you mean by purge? Vomit?
- Zelphyr 8y agoI don't remember where I heard that. Looks like I'm wrong and the worst it may do is cause stomach cramps and bloating.
- cube2222 8y agoHoney loses these effects when put into water over 44 degrees Celsius warm though. That's why you should first make your tea, wait till it cools off, and only then add honey.
- amluto 8y agoCitation needed, please. As far as I know, honey has two material effects: it is tasty, and there are some studies suggesting it’s an effective cough suppressant. I’ve never heard of either one being temperature dependent. I’ve heard people claim that local honey has anti-allergy properties. I would certainly believe that the active ingredients in pollen are destroyed at high temperatures. But AFAIK any purported benefits are entirely unsubstantiated, and the FDA notes that bee pollen can be actively dangerous to people who are allergic to the pollen. P.S. I drink my tea above 44 C.

- opk 8y agoA don't forget to add a tea bag and it'll be perfect. :)
- russh 8y agoToss a little tea in there and it's pretty good.
- andybak 8y agoSkip the lemon and swap honey for sugar and you can make me one while you're at it. Twinings or PG Tips preferably...

- tj-teej 8y agoAnd a shot of strong Irish Whiskey!
- teh_klev 8y agoIndeed! Hot water, a large measure of Powers Whiskey, honey and a chunk of lemon with cloves pushed into the skin. Leave to steep for 6-7 mins, give it a stir. Top notch for the alleviation of colds and, well, anything really :)
- WalterSear 8y agoAnd a little camellia sinensis.
- chaotic_clanger 8y agoThose who say there's nothing like a nice cup of tea for calming the nerves never had real tea. It's like a syringe of adrenaline straight to the heart! When Alice first drinks Grasshopper Tea sorry, could not resist the quote :)
- philipodonnell 8y ago... yeah why didn't they compare the same tea infusion with and without l-theanine?
- Leary 8y agodoesn't tea contain l-theanine?
- ninjakeyboard 8y agoYes it does. But not in large quantities. The study doesn't seem to suggest very large doses of L-Theanine were used either though. I usually take 5-10x what they were using in the study :P maybe I should reconsider my dosing.
- londons_explore 8y agoMassive "slight of hand" omissions like this is scientific papers are really problematic. The research isn't bad, but the implied finding is. It should say "Hot water with tea flavouring and L-theanine has a measurably different effect on humans than cold water". This paper will no doubt lead to a whole wave of dietary additives, fooling millions of people into thinking they're doing something with scientific basis. What can the science community do about it? Restrict papers without peer review? Require per-institution "scientific method" inspectors? Something else?
