Title: How Is My Thirst Quenched So Quickly !
Post by: neilep on 19/02/2007 00:21:04
Wocha Peeps,

Boy me was thirsty earlier !!...Isn't quenching a thirst so wonderful  ?

Two main questions for ya.

What is happening as happy thirst- quenching liquid is being swallowed that it then gives thirst relief so quickly ?

Also, me had a curry tonight !...yummy !!...lots left and plenty to go round !...but why does consuming it make me thirsty so very quickly  ?..I wasn't thirsty before eating said curry ...but during I became thirsty very quickly and needed a good pint and a half to satiate thirst making nastiness !! (not all in one go but in a good few measured prolonged gulping sessions !!).....so..what's that all about ?

Thanks

Anybody want an onion bhaji ?

Could it be the capsiathin?

I would hazard to guess that the key is not the hot spicy part, but perhaps salt that may accompany the other spices to add to the delishous flavor of which you speak!

Water is in any case not the best thing to dowse chilli with - better to do it with milk.

Because capsaicins are not water-soluble, drinking milk (with milk fat and proteins) rather than water is a more effective way to quench the fire caused by hot peppers.

Ofcourse, there are other spices in curry besides chillis, but I am not sure that any of the others will be comparably hot, although they will add far more to the flavour.

Completely agree that a dairy product such a yogurty drink is the best way to quench a hot mouth...and that in fact water has little if no effect...this is scientifically provesn........hence the fact that Indian restaurants have a yogurty drink on the menu.

However..I am not a chilli man...I can not handle HOT foods... I think it's all heat and no flavour,

But it may as well have been just a sunday roast.................I have a feeling it may have been the alacrity implemented whilst eating said Indian deliciousnouss !!

Hmmm..............I would still like my first question answered as to how does a 3 second drink quench a thirst so quickly.....Clearly a signal is being sent from tummy to brain......though I am aware that as far as the biology of the matter...the quenching of the thirst is a sign to stop drinking and that it does in fact take a good while before the liquid fixes the body of the thirst.

Yes dairy products are best, i think water actually makes things worse by livening up the capsiathin.

as to your other question, i am not too sure of the actual name for it, but i think it is the same process as when you are really thirsty.
the first mouthfull always tastes better, than the rest.

You will find the answer in a Dr Karl podcast, im sure chris does not mind me mentioning this as he has made references to Dr Karl in both his radio show and on here.

Milk and Yogurt are excellent ways to combat heat....or something sweet will offset it!

The reason is that curry is stuffed full of salt, usually gram loads of the stuff. Much of this gets absorbed in the small intestine and makes the blood more concentrated. This is detected by a region of the brain's hypothalamus, which triggers thirst sensations when the blood becomes too salty. 

Another thirst-provoking stimulus is low blood pressure caused by haemorrhage. In response to blood loss the kidney starts conserving sodium, boosting the concentration, which triggers thirst.

So the capsaicin (the hot stuff) isn't responsible. I don't think it's very well absorbed, which is why it provokes a RRR the next day.

So, what is the process of quenching my thirst ! ?

Could it be that drinking the liquid quickly dilutes the salts and easily makes them a bit less harsh in your mouth. It seems that thirst happens after eating salty foods and that the salt in fact may dry your mouth out as well as your throat leaving a coating of salt inside until you have removed it by basicly rinsing it away with water or other liguid.what do you think..LOL I havent a clue!! LOL

LOL..I don't know Karen Mam..that's why I'm asking ..LOL !!........Still your speculation sounds great to me !

I just guess peeps like Dr Chris just do not know !!!  *goads them into answering the post*

So perhaps Chris did kind of give and answer , if the small intestine is filled with the salt it has trapped and has concentrated in there then it signals the brain that the blood is to salty, so it kind of makes sence that if you drink something that it will go to the intestine and dilute said concentration of salt shutting off the thirst trigger in your brain,,,something like that.. How does that sound..? I wonder if that is even in the ball park for a hypothesis?
