The health impact of coffee has been
a controversial topic, with advocates
pushing its antioxidant activity and brain
boosting ability, and others criticizing
the downsides such as insomnia,
indigestion and an increased heart
rate and blood pressure.

But the latest wave of studies
brings a wealth of good news for
coffee lovers.

Coffee is good for you, when consumed
in moderation.
It's high in antioxidants and linked
to a reduced risk of many
diseases.

The potential health benefits associated
with drinking coffee include protecting
against type 2 diabetes, Parkinson's
disease, liver disease, liver cancer,
and dementia.

Other studies have found that coffee
drinkers may have a reduced risk of
cardiovascular disease (including
heart attack, heart failure, and stroke.


Coffee also appears to improve cognitive
function and decrease the risk of
depression.

Although coffee may have benefits,
keep in mind that other beverages, such
as milk and some fruit juices,
contain nutrients that coffee doesn't.

Also, adding cream and sugar to your
coffee adds fat and calories, up to hundreds
of calories in some cases.

Like many other foods and nutrients,
too much coffee can cause problems,
especially in the digestive tract.

But studies have shown that drinking
up to two 16 oz cups of coffee per day
is safe.

Caffeine
is an alkaloid.
It is found in over 60 plants, such
as cola nuts, coffee, tea, and
cacao beans.

Caffeine is a white powder which dissolves
easily in water and has a slightly
bitter taste.

Much of the caffeine that is removed from
coffee is sold to pharmaceutical and
soft drink companies.
For coffee to be called "decaffeinated,"
it must have at least 97% of its
caffeine removed.

The most well-known source of caffeine
is the coffee bean, a misnomer for the
seed of Coffea plants.

Beverages containing caffeine are
ingested to relieve or prevent drowsiness
and to improve performance.

To make these drinks, caffeine is
extracted by steeping the plant product
in water, a process called infusion.



Caffeine is classified by the US Food
& Drug Administration ( FDA ) as
generally recognized as safe.


Under 500 mg of caffeine a day is
considered to be safe for most
healthy adults.
That's roughly the amount of caffeine in 4
cups of coffee, 10 cans of soda, or
2 "energy shot" drinks.
Keep in mind that the actual caffeine
content in beverages varies widely,
especially among energy drinks.


Toxic doses, over 10 grams per day for an
adult, are much higher than the typical
dose of under 500 mg per day.


There are 1,000 milligrams (mg)
in 1 gram (g).


A 20 oz. cup of dark roast coffee
has 340 mg of caffeine in it, so you
would have to drink between
15 and 30 of them before it's
considered to be toxic.

 


Caffeine is a central nervous system
stimulant that reduces fatigue
and, at normal doses,
caffeine has variable effects on learning
and memory, but it generally improves
reaction time, wakefulness,
and concentration.

Caffeine can produce a mild form of drug
dependence, associated with such as
sleepiness, headache, and irritability, when
an individual stops using caffeine after
repeated daily intake.


Caffeine sometimes increases the
effectiveness of some medications,
such as those for headaches
like Excedrin.
Caffeine was determined to increase the
potency of some over-the-counter
analgesic medications by 40%.


You may want to cut back if you're
drinking more than 4 cups of
coffee a day (or the equivalent) if
you're experiencing side effects
such as:


Migraine

  headache

  Insomnia

  Nervousness

  Irritability

  Restlessness

  Frequent urination or inability
to control urination

  Stomach upset

  Fast heartbeat

  Muscle tremors

Can you flush caffeine out of your
system?

The effective way to get rid of your
jitters is to flush out your system
with water.
Drinking water will decrease the
effects of caffeine in a relatively
short time.




Caffeine Content of
Some Beverages:


The good old Mountain Dew has 54 mg
of caffeine per 12 fl. oz.
 
Mello Yello, contains 53 mg.

Many caffeinated beverages contain
between 40 and 50 mg of caffeine,
including Diet Coke and Diet
Dr. Pepper.

Soda containing less than 40 mg of caffeine
per 12-oz. serving include Coca-Cola
and Coca-Cola Zero, which both contain
35 mg of caffeine, according to
the Mayo Clinic.

Diet Pepsi and Pepsi contains between
36 and 38 mg of caffeine per serving.

Excedrin - 2 doses - 130 mg
Pepsi Wild Cherry - 38 mg
Tea, 5 min. steep - 5 oz - 40-100 mg

Chocolate - 1 oz - 1-35 mg

Caffeine is naturally found in cocoa beans,
so most chocolate has at least some of
the energy-boosting compound.

 
The U.S. Food & Drug Administration
regulates how much caffeine a 12-oz.
drink can contain, which is
71 mg per serving.

Caffeinated soda that contain this limit or
almost at the limit include Mountain
Dew MDX and Coke Blak.
This amount is comparable to one shot
of espresso, which contains
75 mg of caffeine.

Some sodas do not contain caffeine,
these include 7-Up, Fresca, Sierra Mist,
Mug Root Beer and Sprite.
That includes all flavors and versions
of these sodas.


The average brewed cup of coffee has
about 320 mg per 16 fl. oz.
