Hey guys, I love coffee and so I am a bit concerned about how much caffeine intake is safe for health in a day.
I usually drink 5 cups of coffee everyday. Please suggest me if drinking that much of coffee is bad for my health.

Thanks in advance.

Depends..

Do a google search and you will get a consensus of around 400mg, or about three 8oz cups of filtered coffee, as the recommended 'SAFE' daily dosage..

But for people with heart conditions, sleep disorders, etc. caffeine isn't advised at all.  True, clinical addiction to coffee is said to occur at the 600-750mg mark of daily consumption.

Me?  I get jittery after 2 cups, and don't sleep a wink if I have any after 6pm (I do it anyway..  Maybe THIS time will be different.. %$#@!!)..  And I get a headache if I don't get my cuppa much after 10am..

So I would say that if you don't have any condition that would predispose a lower dose, and you aren't otherwise adversely affected by your current regimen, I would just keep on trucking..

But that's me..  :)

It's recommended to consume not more than 3 cups a day. People with high cholesterol levels and high blood pressure should drink even less coffee- one or maybe two cups a day.

Seems like you got addicted to caffeine. That's why that "headache" you get when you don't drink coffee. However, it never was the case with me. I used to drink 8-10 cups of coffee a day 2 years ago. But I ain't felt anything strange. Thanks for telling me about filtered coffee, I think I should switch to filtered one now.

And by filtered coffee I mean drip, press, etc..

Espresso has less caffeine in it, as does instant coffee.

How about "Green Coffee"? I have heard that green coffee is actually very beneficial for health. I have never tried it. I'm a regular coffee drinker but I never tried green coffee. Can anybody tell how it taste like? Is it more expensive than espresso?

Maybe a statement of the Deutsches Grünes Kreuz regarding coffee intake can help: Drinking two, three, four or even more cups of coffee a day has positive effects on numerous internal organs and body functions. There even seems to be a protective or preventative effect in some diseases. In in most cases, there is no reason to stop drinking coffee for medical considerations. However, in individual cases it's advisable to consult your doctor, especially during pregnancy.

This recommendation is based on up-to-date medical studies that show, for example, that in contrast to popular belief there seems to be no correlation between chronic hypertension (high blood pressure) and coffee consumption, that coffee contains protective antioxidants, and that, in contrast to decaf by the way, it has no negative effect on blood sugar levels or LDL cholesterol. People who regularily drink coffee seem to have a reduced risk of developing renal cancer, prostate cancer, breast cancer, bowel cancer and bladder cancer. Scientists involved in an ongoing 23-year-long research by the Harvard School of Public Health state that "the overall balance of risks and benefits are on the side of benefits". Other studies suggest that coffee consumption reduces the risk of being affected by Alzheimer's disease, Parkinson's disease, heart disease, diabetes mellitus type II, cirrhosis of the liver, and gout.

The main pharmacological effects of caffeine are as follows:
  • stimulation of the central nervous system
  • increase of the pulse rate
  • dilation of the bronchia
  • weak diuretic effect
  • contraction of brain vessels, and dilation of peripheral vessels
  • slight increase of blood pressure
  • increase of bowel peristalsis
  • contraction of the gall bladder
  • stimulation of glycogenolysis and lypolysis

So, consumed responsibly coffee might even be good for your health.

Are you a Dr?
There are studies that do not support your assumption regarding High BP.
None sponsored by Coffee concerns, BTW.






EDIT...sorry Nobby-Norb, I didn't see your fine post in my haste to post mine!

It is my humble request please don't post any answers about coffee consumptions until you're very sure of. Coffee contains caffeine whose overdose is not good for health. That I know. But how much of it? I'm just curious if anybody knows what should be the correct quantity of coffee intake in a day. It is because I love coffee and I want to drink it all day. But I'm afraid too that it may create addiction.

Please help!

Drinking high quantaties of coffee over a period of 6 to 15 days, you might develop a tolerance towards caffeine. This is because caffeine interacts with the adenosine receptors in your body, which are located in the cell membrane and up-regulated, when stimulated continuously, i.e. the cell produces more receptors than usual, so that it requires a higher dose of stimulants to activate them.

There can be sort of a physical and psychological addiction. Stop drinking coffee in a situation like that might lead to withdrawal symptoms like headache, drowsiness, depression, lack of concentration, discontentment, lack of energy or slight nausea, which are usually only short-lived. The signs usually start about 12 to 24 hours after last intake, are most severe for one or two days and pass completely after two to nine days. Since coffee is a legal drug and freely available, that's not really a problem. Like I said there's no danger to your health, when consumed responsibly, which does include even five cups per day. The notion that coffee is bad for your health has been outdated for quite a while, but it's a folklore that still lingers in the heads of a lot of people, even old-fashioned practitioners.

An overdose of caffeine (more than 1 g taken at once, which equals at least five cups of drip coffee or five double shots of espresso or 10 liters of cola or about 12 cans of energy drinks) can lead to signs of excitement like tachycardia and extrasystoles, raised blood pressure, sleeplessness, agitation, headache, and diarrhea, depending on the dose. A severe intoxication might even cause a syncope. For an otherwise healthy human being, the lethal dose for caffeine is about 10 g, again taken at once.

This information is as sure as evidence based medicine goes.
