Very often men drink coffee in order to increase their efficiency, to cope if necessary with drowsiness, to increase physical endurance and speed of thinking. Men working at night, always take a thermos with an instant drink. And indeed, for a while caffeine will have a toning effect.

The quantity of antioxidants possessing anticancer qualities in ground coffee is 4 times more than in tea.
Phenolic compounds are perfectly liberated by the action of high temperature water, however long boiling can destroy unstable compounds. That's why it is not recommended to boil the drink, but only to bring it to a boil.
Scientific research in this field found a 15% decrease in the development of colorectal cancer in people who consumed 3 to 4 cups of the drink every day.

This fact led to the conclusion that for people who have constant high blood pressure levels, the use of small doses of natural coffee will help maintain the vessels healthy and avoid problems in the work of cardiac activity.
12. DECAFFEINATED COFFEE
Nobody specially created this drink, it all happened by chance. During transportation, the cargo with grains was saturated with sea water; it was dried, fried and found that the content of caffeine in it became significantly less. It happened in 1903. Since then, decaffeinated coffee has appeared on the market. Today, the caffeine content is reduced with a special solvent.
