Coffee helps to strengthen small blood vessels.
Drinking coffee, as it turned out, helps small blood vessels work better. To such a surprising conclusion was made by Japanese experts in the field of healthy nutrition of the University of the Ryukyus in Okinawa.
A study involving 27 healthy adult volunteers for the first time in the history of science showed that drinking caffeine significantly improves blood flow to the finger by which to assess the work of the small blood vessels of the body. Consumed coffee volunteers improved the blood flow in the small blood vessels by 30% over 75 minutes compared to those who drank decaffeinated coffee. The researchers emphasize that their findings indicate the ability of the heart to affect the cardiovascular system positively.
The results of this experiment provide mankind with new information about one of the most popular soft drinks in the world. Previous studies have shown that consumption of coffee is associated with reduced risk of death from heart disease and strokes, and that high doses of caffeine improve the functioning of the major arteries. Note that the participants in this study were not coffee drinkers, and their average age ranged from 22 to 30 years.
The level of blood flow in the finger was measured using Doppler flowmetry is a noninvasive technology that evaluates the blood flow at the microscopic level. The experiment was repeated in intervals of two days, the volunteers varied groups depending on who drank coffee with caffeine and who is not. In this experiment participants did not know what kind of drink they get. The researchers also evaluated blood pressure, heart rate and resistance vessels.
