The
Truth About Caffeine
How
many of you here consider yourself caffeine addicts? How much coffee
do you drink a day? One cup? Two cups? More? How about caffeinated
sodas?
Caffeine
is pervasive in our society these days and every few months we hear
about how a study has shown that it is bad for us or good for us.
What are we to believe?
Today
I'd like to give you some of the facts about caffeine and its effects
on your body. It may not cause you to change your coffee consumption
but at least you'll be better informed about what you are putting
into your body.
I'm
going to talk about the beneficial effects of caffeine, the negative
effects and discuss what are considered safe levels of caffeine
consumption.
Let's
start with the good news. Caffeine, which comes from the leaves,
seeds and fruits of about 63 different plants, is well known as
a stimulant. That's why people drink it, right?
Caffeine
does help you wake up and feel more alert and it has been shown
to increase attention spans. This is a beneficial effect for people
who are driving long distances and for people who are doing tedious
work. Calling this a health benefit may be stretching it, though
staying awake while you are driving a car is definitely a benefit
to your well-being!
Caffeine
also contains antioxidants which have been shown to have cancer
prevention qualities.
The
negative effects of caffeine are largely dependent on how much you
consume.
When
consumed in small quantities like, for example when you have one
cup of coffee or one soda, caffeine can cause your heart rate to
increase, you urinate more which can cause dehydration, and your
digestive system produces more acid.
In
larger amounts, caffeine can cause you to have headaches, feel restless
and nervous, be unable to sleep, and even, in very large quantities
to have hallucinations.(Don't try that at home!) When larger amounts
of caffeine (over 600 mg per day) are used over long periods of
time you can develop sleep problems, get depressed and have problems
with your digestive system.
According
to a Medline article on the National Institutes of Health website,
having caffeine in your diet is not of any benefit to your health
but moderate consumption is also not considered harmful.
They
say that having up to 3 eight ounce cups of coffee a day or 250
mg of caffeine is considered (quote) "average or moderate".
10 cups of coffee a day is considered excessive. Also, remember
that the amount of caffeine per cup can vary greatly depending on
the type of beans that are used and the strength of the brew.
Most
sodas with caffeine, unless they are specially enhanced like "Jolt"
or something like that, have about 35 mg of caffeine per 8 ounces
so you don't have to worry too much unless you are drinking several
2 liter bottles per day. Also, the effect of caffeine on you personally
will depend on a number of factors like your weight, general health,
mood and personal sensitivity to caffeine.
You
can see that caffeine can have both positive and negative effects
on our health and well-being but the bottom line is that if you
drink your coffee or sodas in moderation, you don't have to worry
too much.
So,
the next time you are wondering whether you should have that second
cup of coffee to perk you up, relax. At least now you know what
it is and isn't doing to you!
