Immune against coffee/caffeine

Post by hurly » Wed Sep 28, 2005 2:20 pm

Please tell me why some people are immune to coffee/caffeine...
I've heard some people saying that they've taken 4-5 cups of coffee without no effect and can still sleep :shock:

i sometimes feel like that too. I think that if you consistently drink caffeine-containg beverages, your body will become less affected by its effects. Something like building a resistence to caffeine. Same like drugs. Everytime you take some, you will need to take a larger amount later to acheive the same 'high'. Caffeine is, after all , a kind of drug.

I'm guessing here. But it may be that they have built up a tollerance to it. Essentially what happens, I think, is that the key enzymes located in the smooth endoplasmic reticulum that detoxify can proliferate if constantly stimulated (exposed to the substance). An increase in these toxic metabolizing enzymes would lead to a higher tollerance to toxins, such as caffeine.

I'm really vague on this subject though. I'm not even sure if this area is where caffeine is metabolized. I'm just guessing. So best wait until someone with more experience verifies, or corrects this.

I would say that it's caused by the body's detox system...there're 2 system which are xenobiotics and antioxydant detox system....I think that someone is immune to coffee's effect because of his/her detox system...(usually anti-xenobiotics do that)...
but, anyway...coffee isn't all bad...in some aspects, coffee is good also.. :lol:

Hey, additional info...caffeine substances also boost you a little in memorizing somethimg...and usually it's good for student who majors memorizing subjects....but it's nothing related with analitical subjects like math, physics and chem... :lol:

Using coffee to boost memory? That is illogical. there are many less poisonous things to do that. Gingseng anyone? Lecitine? Anyway i totally disagree with coffee, but that is just me...

I love coffee before the mid-terms and finals. :)

Correct me if I'm wrong, but coffee doesn't anything but keeping you awake? I don't think it increases your concentration ability....
When talking about concentration, what chemicals does actually boost your concentration? Only ginseng and lecitine? :shock:
