In a glass of natural ground coffee, brewed with 7-10 g of coffee, there is 120 to 200 mg of caffeine. In a glass of instant coffee prepared with 2.5 g of coffee extract - 65 mg of caffeine, and in a glass of decaffeinated coffee - 4 mg.

Decaffeinated coffee: how is it made?

Decaffeinated coffee is mainly obtained by three methods. Each uses green, unroasted coffee beans that are soaked in a suitable solvent or steamed until the pores of the coffee beans are opened and the caffeine is extracted. The coffee beans are roasted only after the decaffeination process. You can get decaffeinated coffee using the following method:

  • extraction with a mixture of solvents- methylene chloride, ethyl acetate and water in a proportion that leaches caffeine from the coffee beans. After the decaffeination process, the solvent is evaporated, so no residues of unwanted chemicals are found in the beans.
  • Swiss(Swiss Water Process) - which uses the osmosis process in an aqueous environment and carbon filters. It is an organic method and no chemicals are used to extract caffeine.
  • extraction with carbon dioxide- uses the passing of gaseous carbon dioxide in a supercritical state through the coffee beans to remove caffeine without affecting aromas and flavors. This is the most expensive method availabledecaffeination.

Decaf coffee: who should be drinking it?

For most people, drinking 1-2 glasses of coffee with caffeine a day (up to 400 mg of caffeine) is not a problem and may not even affect your well-being.

It should be remembered, however, thatcaffeine tolerance is an individual feature . Different people react differently to the concentration of this active substance. Caffeine:

  • has a stimulating effect
  • improves concentration and reflexes
  • increases the strength of heart contraction
  • accelerates metabolism

Long-term excessive caffeine consumption (over 500-600 mg) can lead to:

  • too excitable
  • feelings of anxiety
  • heart arrhythmia
  • insomnia
  • headaches

Replacing regular decaffeinated coffee is recommended:

  • pregnant and lactating
  • with insomnia
  • in anxiety states
  • for headaches
  • for irritability
  • for nausea

and especially people with hypertension and kidney diseases.

When taking medications, you also need to pay attention that they do not interactwith caffeine . There are suggestions in the literature that women of working age should drink less than 300 mg of caffeine per day. People with estrogen dominance should also be careful about caffeine, so replacing morning coffee with a decaffeinated version seems justified.

Decaffeinated coffee is a very good source of antioxidants (mainly polyphenols and hydroxycinnamic acid), i.e. substances that inhibit the action of free radicals, cause low-intensity inflammatory processes, damage proteins and DNA and lead to many diseases.

When analyzing the Western diet, it was found that coffee is the main source of antioxidants in it. The antioxidant content of decaffeinated coffee can be up to 15% lower than that of non-decaffeinated coffee.

In decaffeinated coffee we can find small amounts of magnesium, potassium and niacin. One glass of the drink covers the body's needs for the individual ingredients listed in the amount of 2 to 5%.

  • liver disease,
  • premature death as a result of a heart attack or stroke,
