Decaffeinated coffee has it the virtues of raw coffee?

In other words, we must determine whether:
1) Caffeine contributes to the beneficial effects of coffee.
2) The extraction of caffeine destroys other beneficial components.
The answer is no to the first question, caffeine has certain virtues, but not essential to health and longevity, and not also to the second, extraction when it uses a good process does not remove other useful components.
So we can replace with decaffeinated coffee and expect the same contribution to health.

Caffeine maintains vigilance. If we take coffee to escape to sleep or waking up, raw coffee is the best and Robusta is the stronger. Instead if we take several cafes in the day, for fun or for its qualities, decaf is what is needed.

The decaffeination process

He operates by washing the whole green beans and again many times. The addition of a solvent or carbon dioxide makes the operation more efficient while preserving the flavors and other compounds.
It is difficult to know which solution was used in a product so you have to trust the producers ... and buy good brands.

Suppose that the most effective method is used. Carbon dioxide (CO2) crosses the grains under the effect of pressure and temperature above 31 degrees. He dissolves the caffeine that is loaded into CO2. Water at high pressure then recover the caffeine. Other compounds are little or not affected.

There will still be between 5 and 10% caffeine remaingin in the grain.
