Excitement, nervousness, sleep disorders, erection problems (in high doses, such as 10 to 12 cups of coffee a day), problems with the metabolic absorption of certain minerals, dehydration, anxiety or fear, heart problems, incontinence (especially in women), dependence (drug, risk of drug dependence due to the increase in the number of adenosine receptors), digestive disorders in the stomach region, generation of a tolerance phenomenon, in children (caffeine content in soft drinks), possible development of hyperactivity.


Cardiac disorders, intensive sports (decreases oxygenation), pregnancy (we believe that this is not an absolute contraindication but it is preferable to avoid coffee), osteoporosis, sleep disorders.


we do not know


– Coffee (beverage) in its most appreciated and economical form, per cup, we count on average 45 mg of caffeine (possible variation depending on the type of coffee, from about 35 to 150 mg of caffeine).

– In tablet form, mixed with other molecules.

– In pills in a simple preparation, to exert an aftereffect (caffeine is released progressively), these drugs are used, for example, by fighter plane pilots in wars to stay awake.

Where does coffee grow?

Coffee grows mainly in hot countries (Central America, Africa, Brazil,…).


– Coffee is a widely consumed beverage in Europe and in the rest of the world, such as the United States or Brazil. Moderate consumption (about 3 cups a day) poses no health risk. On the contrary (read below in Death Rate and Coffee ), it could reduce the death rate.
However, for sensitive people (especially children) or in high doses, coffee can have the following harmful side effects: fear, anxiety, nervousness, diarrhea, heart problems, headaches, hyperactivity…
If you have any of these effects side effects, reduce your consumption or stop completely. It may be advisable to drink black tea or green tea which also has a stimulating effect but less concentrated in caffeine (theine).

– Caffeine (the active ingredient in coffee) is used in numerous pharmaceutical preparations, such as in the sleep effect of medication (in antiallergic drugs, in medication against travel pain) or to activate and potentiate the effect of certain analgesics (paracetamol, AAS ). It is also interesting to mention a study that proves that women who consume more than 5 cups of coffee a day have more difficulty getting pregnant. However, coffee still has a preventive role in numerous diseases (including cancer), so the benefit of drinking coffee is greater, and it is therefore advised for the population (less for sensitive people).

– In a coffee, for example, an espresso made from Coffea arabica L. (coffee tree from Arabia), there are more than 1,500 molecules besides caffeine, half of which are volatile substances. That’s why some experts believe that coffee is the most complex beverage in the world.

– Drinking 1 to 4 cups of coffee a day would reduce the risk of melanoma by 25%  , a severe form of skin cancer. This meta-analysis (study of studies) was published in November 2015 in the specialized journal American Journal of Clinical Dermatology and compared coffee drinkers with those who do not consume this beverage. Apparently, several antioxidants found in coffee interfere with the action of the sun’s UV rays at the cellular level, which decreases tumor formation.

– To reduce the risk of esophageal cancer , coffee should not be drunk at a temperature above 65°C. These WHO recommendations, more specifically from the International Agency for Research on Cancer (IARC), based in Lyon (France), are from June 2016.

Death Rate and Coffee
– People who drink about 3 cups of coffee may live longer than those who don’t drink coffee. These results come from 2 studies, one European and one American, published in July 2017 in the specialized journal Annals of Internal Medicine🇧🇷 In the first study, the largest study of its kind, scientists analyzed data from more than half a million people in 10 European countries, including France and the UK. Scientists have found that compared to non-coffee drinkers, coffee drinkers have a significantly lower risk of death, i.e. a lower risk of dying from diseases such as cancer or cardiovascular disease. The second study found that higher coffee consumption was associated with a lower risk of death among black and non-black populations. The mortality rate was the same for caffeinated and decaffeinated (decaffeinated) coffees.
– According to a British study, drinking 3 or 4 coffees a day brings more benefits than health risks, except in pregnancy and in women at high risk of fracture. This major review umbrella review ) showed that coffee consumption was consistently associated with a lower risk of death from many causes and of heart disease, the most important reduction in the relative risk of death is related to the consumption of 3 cups of coffee a day compared to those who don’t drink coffee. This study was published on November 22, 2017 in the scientific journal BMJ (DOI: 10.1136/bmj.j5024).
