In the News: Coffee as medicine? Japanese scientists show how it helps the heart

Dunkin Donuts coffee for health!
Being a HUGE Dunkin' Donuts coffee drinker (and scientist) that I (Rob) am, I LOVE when coffee and science come together and prove great things about coffee. :) Here's one such study from Japan.
Drink up!!

In the News: Coffee as medicine? Japanese scientists show how it helps the heart

A study presented last week (week of Nov. 17, 2013) at the American Heart Assn.’s Scientific Sessions meeting offers new evidence that coffee boosts the function of small blood vessels in people who are already healthy.
Researchers in Japan recruited 27 young adults in their 20s to participate in the study. None of them were regular coffee drinkers, but they agreed to consume two 5-ounce cups of joe for the sake of science.
On one of the days, the coffee was caffeinated. On the other day, they drank decaf. They weren’t told which was which. Neither were the researchers, who measured the volunteers’ blood pressure and blood flow after they finished their beverages.
All the medicine you need
The researchers placed a probe on the tip of each volunteer’s left index finger or thumb and used a technique called laser Doppler flowmetry to measure blood flow to the digit. It works by shining a laser beam through the blood and measuring how much it is scattered by the movement of red blood cells. For the study, the researchers interrupted blood flow to the hand for one minute, Dr. Masato Tsutsui, the cardiologist who led the study, said in an email to The Times. When the minute was up, they monitored how quickly the normal blood returned to the finger or thumb.]
It turned out that blood flow measured in the finger or thumb was 30% higher on the day they had regular coffee than on the day they had decaf. This was significant because the measurements are a proxy for how well the small blood vessels in the body are working.
That wasn’t the only change. Blood pressure rose “significantly” as well on the days the volunteers drank regular coffee, according to the study abstract. But the caffeine didn’t cause the volunteers’ hearts to beat more quickly.
The researchers also measured levels of the neurotransmitters epinephrine (also known as adrenaline) and norepinephrine in the volunteers’ blood plasma. The levels were essentially the same after drinking both types of coffee.
“This gives us a clue about how coffee may help improve cardiovascular health,” Tsutsui said in a statement from the American Heart Assn. Tsutsui is a professor of pharmacology at the University of the Ryukyus in Okinawa, Japan.
If scientists can figure out how caffeinated coffee helps small blood vessels work better, “it could lead to a new treatment strategy for cardiovascular disease in the future,” he said.
 But this is probably not the only reason why many studies have linked coffee consumption with better cardiovascular health, he said via email. Instead, he said, it’s “just one of many.”

Gift/Memorial Suggestions

Several of our friends have lost loved ones (human and pets) and we found that one of the best ways to honor their memory is to give to an animal charity.
What better way to recognize a life of love, than by giving another life a chance for love?
We donate to many animal rescues, but because we volunteer with
DC Weimaraner Rescue and Coast-to-Coast Dachshund Rescue, those are our 2 favorites.
Consider giving the chance of life to a dog or cat.
