Caffeine is an alkaloid found in
both the seeds and leaves of coffee, tea, cacao, cola and mate plants. A cup of
coffee contains about 50 mg of caffeine and its stimulant action, which lasts
for one or two hours after it has been drunk, acts on the cerebrospinal nervous
system, heightening our mental faculties, keeping away sleepiness, boredom,
fatigue (including mental fatigue) and depression. It bolsters memory, learning
capacity, perception and concentration, and facilitates the perception of
sensory stimuli; it also abates headaches and migraines.
ABOUT THIS ARTICLE
Reposted from Lavazza coffee website:
The scientific community agrees on
the amount of caffeine that can be consumed in a day, indicating 300 mg/day of
caffeine for an adult, i.e. about 4-5 mg of caffeine per kg of body weight per
day: e.g.:
a man weighing 70 kg (154 lb) = 4.5 x 70 = 315 mg.
To get an idea of what it means in terms of dose, these
are the quantities of caffeine contained in some of the most common
beverages/foods:
Espresso or mocha
coffee 40-80 mg per cup
American coffee
115-120 mg per cup
Instant coffee
65-100 mg per cup
Decaffeinated coffee
< 5 mg per cup
Cappuccino 70-80 mg
per cup
Chocolate 30-40 mg
per 60-g bar
Tea 40-50 mg per cup
Cola drinks 35-50 mg
per can
Energy drinks with
caffeine or guarana 50-100 mg
