Coffee is one of the most
consumed drinks in the world. It is grown in more than 70 countries, with the
two largest producers in the world being Brazil and Colombia. Canada's climate
does not allow coffee to be grown, but there is a lot of processing of imported
grain. Canadians are estimated to drink more than 15 billion cups of coffee per
year. The average coffee consumer drinks three cups a day. Contrary to what one
might think, coffee contains vitamins and minerals as well as antioxidant
compounds.
Active principles and
properties
Bioactive compounds
Coffee contains more than a
dozen bioactive compounds, most of which are formed during the process of
roasting the grain. Three of them are in high concentration and are important
from a physiological point of view. These are caffeine, diterpenic alcohols and
phenolic compounds known for their antioxidant effects1.
• Caffeine. This compound is
by far the one that has been best characterized so far in coffee. In the United
States, it is estimated that 75% of the caffeine consumed comes from coffee2.
In Canada, this quantity has been evaluated at 60% 3. The rest comes from tea,
chocolate, energy drinks, etc.
The caffeine content of
coffee varies according to the type of beans, roasting method and method of
coffee preparation (for more details, see our Caffeine fact sheet). Caffeine is
known mainly for its stimulant effects4. In healthy adults, a small amount may
increase alertness and concentration. In other people, however, it can lead to
unwanted biological effects such as insomnia, headaches, irritability and
nervousness. According to Health Canada, in adults, caffeine consumed
moderately (three cups of coffee per day) has no adverse effects, particularly
with regard to behavior (anxiety, attention span), cardiovascular health or
cancer3.

• Most data on the link
between coffee consumption and chronic disease reduction were obtained from
epidemiological studies. According to some researchers, these results must be
interpreted with caution, as they may include methodological bias13. For
example, how to calculate the amount of coffee and caffeine consumed daily can
vary greatly from one study to another (variation in the size of a cup of
coffee, the duration of infusion, the type of grain used , etc.). In addition,
some "confounding" factors such as alcohol consumption and cigarette
smoking, often associated with high coffee consumption, are not always well evaluated.
• It should be kept in mind
that coffee is only one of the modulators of the risk of certain diseases.
Despite some consumption benefits, it is prudent in a public health context to
recommend moderation. Which means, in more concrete terms, a consumption of three
cups of coffee per day or 400 mg to 450 mg of caffeine daily. According to
Health Canada, this quantity does not represent a hazard to human health
