Coffee and caffeine
Wrote at 16:15 by Stefano Urso in: Coffee Quality,
From a nutritional point of
view coffee is not an essential food for the body, but some substances in it
cause beneficial effects to certain organs of the human body. The habit of
daily consumption does not imply tolerance even after long periods but, as with
any food, you must not abuse it if you do not want to get side effects such as
tachycardia.
Coffee contains caffeine which, in combination with acid caffettaninnico, acts primarily on nerve centers causing a feeling
of general well-being, encourage to be more vigilant and active both physically
and mentally. Effects are also on the lungs with pulmonary dilatation, on
skeletal muscle by enhancing the ability of muscle contraction, on heart as
cardiobooster, on the walls of the stomach by promoting the secretion of
gastric juices (improving digestion, etc.), etc.
Caffeine is into coffee seed
but into the coffee plant leaves too, further also into plants like tea, cocoa,
etc. A cup of coffee contains between 50 and 150 mg of caffeine, the difference
depends on the mode of preparation of coffee. For example, the filtered coffee
contains more caffeine compare to caffè
espresso because during the slow filtering filter process the water
dissolves a larger amount of caffeine from coffee powder compared to that
released by the typical preparation of espresso coffee that
provides a fast passage of water pressed through coffee.
It should be noted that the
actions on the heart are quite minor and are not detectable in the daily doses
of 2-3 cups.
