Coffee as blood vessels medicine: Drink coffee for healthy heart, blood pressure
Coffee as blood vessels medicine and coffee for a healthy heart and healthy blood pressure was the finding of a Japanese research study that was presented at the American Heart Association's Scientific Sessions 2013 this week. “The next time you take a coffee break, you might want to consider a triple espresso. The extra caffeine may reduce your risk of dying from cardiovascular disease,” reported the Los Angeles Times.
Coffee drinkers around the world, smart coffee drinkers that is, already know from their own experience that a healthy amount of coffee has a positive effect on blood vessels, blood circulation, and the heart. Coffee also works as a great natural way for low blood pressure.
Coffee drinkers who skip that morning coffee or afternoon coffee, especially in Europe, know that coffee and blood vessels are somehow related. Feeling sluggish or getting a headache after skipping that morning coffee can easily be caused by decreased blood vessels function and blood circulation.
What many people already know or have sensed about the effect of coffee on blood vessels has now been the results of a research study conducted by Japanese scientists.
After drinking 5-ounce cups of coffee (for the sake of science), the blood pressure and blood flow of 27 young adults in their 20s was measured by placing a probe on the tip of each volunteer’s left index finger or thumb. The technique called “laser Doppler flowmetry to measure blood flow to the digit" works by shining a laser beam through the blood and measuring how much the laser beam is scattered by the movement of red blood cells.
The measurement, which was applied after interrupting the blood flow to the hand for one minute, indicated how well the small blood vessels in the body were working again after drinking coffee. “It turned out that blood flow measured in the finger or thumb was 30% higher on the day they [the coffee drinkers] had regular coffee than on the day they had decaf.”
Measuring the coffee drinkers’ blood vessels performance, blood flow, and blood pressure after the coffee consumption, showed not only an increased blood flow but also that the blood pressure rose “significantly” on the days that the volunteers drank regular coffee.
While there was a difference in blood vessel performance depending on whether the test subjects drank regular or decaffeinated coffee, researchers found that drinking coffee also had an effect on the levels of the neurotransmitters epinephrine (also known as adrenaline) and norepinephrine in the volunteers’ blood plasma but that the kind of coffee did not make a difference.
Epinephrine (also known as adrenaline) and Norepinephrine (noradrenaline) are neurotransmitters and a hormone that are involved in controlling a person’s heart rate, blood vessels, bronchial airways, blood sugar levels, converting bodily fats to fatty acids, and a person’s fight-or-flight response.
After the Japanese research findings of the effects of coffee on blood vessels, Tsutsui, a professor of pharmacology at the University of the Ryukyus in Okinawa, Japan, said in a statement from the American Heart Association that this gives us a clue about how coffee may help improve cardiovascular health.
