Some
of us just can't get through a morning or even a day without caffeine!
A good many studies have been done about caffeine but the results
and conclusions tend to vary, contradict or change as technology evolves.
We had a hard time figuring out what to believe. So Whole Latte Love
decided to do some good old investigative research on the subject
of coffee and caffeine.
Do
I need a 12-step program to kick coffee?
Caffeine is known in the medical world as trimethylxanthine. It can
be used medically as a cardiac stimulant or as a diuretic. Some studies
seem to say that caffeine acts like drugs such as amphetamines, cocaine
or nicotine. These studies suggest that caffeine affects the part
of the brain that triggers functional activity in the shell of the
nucleus accumbens (the part of the brain responsible for addiction).
This seems to be old news. Recently French researchers have discovered
that caffeine does not affect the area of the brain that involves
addiction at doses of one to three cups a day. It will increase alertness,
but minus the addictive dependence.
What’s
in my cup?
The amount of caffeine that is in your coffee depends on many variables.
Drip coffee has about 100mg of caffeine in a six-ounce cup. A double
shot of espresso has about 50mg of caffeine. You thought espresso
was stronger, huh?
There are two main reasons for this surprising fact. In the coffee
world there are two important coffee plants: Robusta (Coffea canephora)
and Arabica (Coffea Arabica). Robusta coffee has historically been
less expensive to grow and contains the highest caffeine content.
Roasting masters of old have developed closely guarded blends of Arabica
over hundreds of years. Coffee connoisseurs consider Arabica the better
bean for a superior coffee. Espresso blends primarily use Arabica.
However some roast masters will blend in some Robusta as a crema enhancer.
Espresso is also pressured brewed with just a small amount of water
per shot. Drip coffee uses the less expensive Robusta coffee, which
accounts for part of its higher caffeine content. It is also exposed
to a large amount of water dripping through a screen or filter. In
general, the more water used for brewing, the more caffeine the drink
will contain.
Is
coffee actually good for me?
The University of Bristol studied research on caffeine’s influence
on cognition and mood. Good news! Coffee helps in the performance
of tasks that require sustained attention. Even at normal times when
alertness may be hindered, such as after lunch or when a person has
a cold.
Will
I fall over and die because I drink coffee?
For a period of time it was thought that caffeine contributed to heart
disease, high blood pressure, miscarriage, and many other medical
problems. Recently with more rigorous testing and better methods The
American Medical Association stated, “Moderate tea or coffee
drinkers probably need have no concern for their health relative to
their caffeine consumption provided other lifestyle habits (diet,
alcohol consumption) are moderate, as well.” Out of all the
studies done there has been no evidence that serious health problems
come as a result of drinking coffee or having caffeine in your diet.
It is recommended that your caffeine intake is no more than 300mg
per day. That’s about three cups of drip-brewed coffee per day.
So, drink up!
