Caffeine
is a mild "stimulant" that has the effect of making you feel
more awake and alert.
A high dose may make you feel jittery and may prevent sleep. Tea, coffee
and soft drinks
are the three major sources of caffeine - but don't forget chocolate.
There are some more
figures "here"
Wordwide,
the main source of caffeinne is Coffee, which is obtained from the beans
of the
coffee bush,
which looks like this when it's in flower, and like this when the beans
are growing.
Coffee
grows in a variety of places around the world, particularly Africa and
the Middle East, each part of the world producing beans with their own
distinctive taste, in much the same way as grapes for wine. In this
country we tend to drink our coffee blended, however.
Tea
is another source of caffeine which originates from China. It was first
introduced into Europe at about 1600 and arrived in the UK about 60
years later.
Caffeine
History
The first historical record of Caffeine use was from Aztec records from
the time of the Aztec leader Montezuma. Caffeine was taken in the form
of a hot drink made with cacao (the 'chocolate' tree) leaves and various
herbs and spices. Montezuma was said to have drunk up to 50 cups a day.
Chocolate in the form of the chocolate bar was first introduced by the
Bristol company Fry & Son in 1847.
Coffee
proved to be a far more popular form of caffeine intake. It is mentioned
in the "Koran". It was introduced into the UK originally as
a medicine but became extremely fashionable between 1670 and 1730 when
there was a massive increase in the number of "coffee houses".
Caffeine Effects and dangers - such as they are!
To
be frank, Caffeine is a pretty safe drug - we used it lots as we worked
on this site! The standard dose is only 200mg (about 2 cups of strong
coffee or 3 cans of caffeinated soft drink) per day. Many people exceed
this dose (in fact I pass it by 8:45 in the morning!)which has been
found to cause "withdrawal symptoms" if intake is suddenly
reduced. It is likely that physical or psychological "dependence"
may occur and many people would be considered to be addicted to, for
example, coffee. As many as 29% of coffee drinkers admit they 'couldn't
do without it'.
Can
you over-dose on coffee? ("Answer")
There
has been some evidence linking caffeine to diabetes in some people as
well as an increase in aggression. It has also been linked to smaller
and later developing babies when large amounts are taken during pregnancy.
"Tolerance"
may also develop quickly, where the user may have to drink, for example,
more and more coffee to get the same 'kick' from it.
It
won't surprise you to know that pretty well this entire website was
written under influence of this drug...........

World Issues
Caffeine is a big issue for countries in the third world. It may sound
silly, but the cup of coffee you drink may be a life-or-death decision
for someone else. To find out what the problem is, click here.
