After water, coffee is the most consumed beverage in the world, with an estimated 2.6 billion cups of coffee per day. For those who want to benefit from its antioxidant properties without the effects of caffeine and without damaging their usual taste buds, there is an increasingly popular alternative: “decaf” coffee. But behind this seemingly ideal proposition lie extraction processes that are not without risks to the health of consumers…

The countries that consume the most coffee are located in Europe, and France is not left out, with more than 5 countries kgkg Its consumption is on average per capita per year. This drink, which has many virtues, is especially appreciated because it stimulates the functioning of the nervous system, through a well-known substance: Caffeine. The latter could be More or less well tolerated Depending on the individual and the quantity consumed, which may lead to sensations such as tachycardia, tremors, nervousness, anxiety, sleep disturbances… That is why more and more health-conscious enthusiasts are turning to decaf coffee, which retains its aroma, minus the caffeine. However, the virtue of “less caffeine” masks vices that our body can do well without being exposed to. Here they are.

Caffeine, Thane: Are they the same thing?

Caffeine is extracted from coffee beans that are still green, i.e. not roasted. There are three processes, where the majority of decaf coffee is produced using methods including: SolventsSolventsBecause it is the cheapest process.

In these two methods, chemical agents with stripping, dissolving and degreasing properties are used, which are controversial because they are also… “It may cause cancer”,according'National Institute for Research and Safety for the Prevention of Work Accidents and Occupational Diseases (INRS).

Therefore, since nothing forces roasters to specify the decaffeination process used, not mentioning it may mean solvent interference.

“100% decaf” does not exist!

The coffee bean contains 1 to 2.5% caffeine. With the mentioned extraction processes, this rate drops to 0.1% after decaffeination. In addition, know that coffee is not the only ambassador of this substance: tea, cocoa, cola, yerba mate, guarana… I assure you that it will be necessary to consume them in excess to obtain appropriate levels of caffeine. “Real” coffee, but it's good to know when you want to limit it!
