Another important aspect to consider when choosing your coffee is its biological origin or not. Compared to traditional, organic coffees have higher concentrations of bioactive compounds and caffeine, they also do not contain pesticide residues and preserve the biodiversity of the ecosystem. The same applies to biological decaffeins, with one of the most common solvents being used, in this case, being water.
This beverage also has many health effects. The main bioactive coffee compounds that have been associated with a positive health effect are caffeine, polyphenols, trigonelline and chlorogenic acid. Several studies show that regular and moderate consumption of coffee by healthy people, that is, as much as 2 to 3 coffees per day (or 300 to 400 mg per day of caffeine-containing beverages) can contribute to the prevention of various chronic diseases. The prevalence of diseases such as diabetes mellitus type 2, liver disease and hepatocellular cancer, as well as Parkinson's disease and Alzheimer's disease, appears to be lower in people who report moderate and moderate consumption of coffee. At the sports level, some studies also suggest that coffee may contribute to improved endurance in long-term exercise.
Mean values of caffeine in various beverages and foods
- Decaffeinated: 2 mg
- Short coffee: 62 mg
- Average coffee: 72 mg
- Full coffee: 88 mg
- Tea (220 ml) – 50 mg
- Coffee (filter, 1 cup, 200 ml) – 90 mg
- 1 can of energy drink (250 ml) – 80 mg
- 1 can of cola (355 ml) – 40 mg
- 1 bar of black chocolate (50 g) – 25 mg
- 1 bar of milk chocolate (50 g) – 10 mg
Although it is considered a safe drink for most people, it should be noted that the sensitivity to caffeine is variable. The most susceptible to its side effects are children, adolescents, pregnant women, the elderly. In case of pregnancy or breastfeeding it is even advised to consume less than 200mg per day of beverages containing caffeine.
Major tachycardia, increased blood pressure, anxiety, insomnia, and gastrointestinal disturbances are among the main symptoms of sensitivity or excessive caffeine consumption (above 400mg per day). However, despite the concerns about the side effects of coffee drinking, there is no clear relationship between its consumption and the increased risk of cardiovascular disease to date.
People who are sensitive to caffeine may choose to consume decaffeinated because most of their nutritional compounds are not significantly affected by the decaffeination process, with the exception of caffeine.
