2. Coffee
A coffee bean is a seed of the coffee plant, and is
the source for coffee. It is the pit inside the red or purple
fruit often referred to as a cherry. Just like ordinary
cherries, the coffee fruit is also a so called stone fruit.
Even though the coffee beans are seeds, they are
referred to as 'beans' because of their resemblance to
true beans. The fruits - coffee cherries or coffee berries -
most commonly contain two stones with their flat sides
together.
A small percentage of cherries contain a single
seed, instead of the usual two. This is called a
"peaberry."
The peaberry is more unusual occurring only
between 10 and 15 percent of the time, and it's a fairly
common (yet scientifically unproven) belief that they
have more flavour than 'normal' coffee beans. Like Brazil
3. Coffee production
Coffee production is the industrial process of
converting the raw fruit of the coffee plant into
the finished coffee. The cherry has the fruit or
pulp removed leaving the seed or bean which is
then dried. While all green coffee is processed,
the method that is used varies and can have a
significant effect on the flavor of roasted and
brewed coffee.
Coffee production is a major source of
income, especially for developing countries
where coffee is grown. By adding value,
processing the coffee locally, coffee farmers

7. Negative effects
In the case of abuse of coffee or other
beverages containing caffeine may occur
following negative effects:
•Tachycardia (increased heart rate);
•Restlessness, tremor (shaking), nervousness,
states of panic;
•Insomnia;
•Seizures;
•Anemia ;
•A slight state of dependency, without coffee
may experience headache (migraine).
8. Positive effects
• Coffee is a beverage that contains no
calories and contribute to the replenishment
of the substances minerals as iron,
potassium, magnesium, and manganese.
Coffee also is a major supplier of vitamins
such as niacin, a vitamin B group, which is
responsible for energy intake, riboflavin,
pantothenic acid, vitamin E, vitamin C and
vitamin B6.
• Positively stimulates metabolism through a
thermogenic effect, a stimulus to burn body
fat, because caffeine. Drinking coffee may

the body and thereby contribute to energy intake of the body.
Caffeine increases adrenaline, increases muscle tension and
muscle contraction capacity. Recent studies show that before
sports tournaments, coffee consumption has positive effects
on performance and extra caffeine stimulates breathing, lung
volume being efficiently exploited.
• Coffee facilitates digestion due to the stimulating effect of
caffeine and its elements, stimulates the secretion of gastric
acid and bile.
• Substances antioxidants in coffee (vitamin B, C, E, carotene,
fat) protects kidney cells by oxygen radicals carcinogen,
compared to tea green that could not prove this effect. After
ten years of research in Japan, of 100 000 people which are
not consuming coffee, of which 514 people died of cancer.
Similar results were obtained in Ottawa in women prone to
breast cancer. Another study by the National Health and
Nutrition Examination Survey published in 2005, shows that
those who consumed at least two cups of coffee daily reduces
the incidence of chronic liver disease, which are common in
alcoholics or obese. The effect of caffeine reduces disease
incidence. It assumes a positive effect in Parkinson's disease
or Alzheimer's.
