Coffee healthy life a cup of coffee is good for activating blood vessels

Drinking a cup of coffee is good for blood vessels. A new study in Japan has found that drinking a cup of coffee can help small blood vessels.

Let the peripheral blood flow more smoothly.

The study was presented at the 2013 academic Symposium of the American Heart Association. The research team of Ryukyu University in Okinawa, Japan

27 healthy adults were enrolled in the study. It was found that drinking coffee could improve the blood circulation at the end of the fingers and participate in the study.

After drinking a cup of caffeinated coffee, the blood flow within 75 minutes of ​​ was 30% higher than that of decaffeinated coffee drinkers.

The lead author of the study, Masahiro Nakai, a professor in the Department of Pharmacology at Thiqiu University and a cardiovascular specialist, said the research evidence showed that drinking coffee

Caffeine may improve cardiovascular health.

Many people have the habit of drinking coffee, and more and more people in the medical profession are doing research on coffee. Past studies have found that there is coffee drinking.

People who are used to it are less likely to die of heart attacks and strokes, and studies have shown that high doses of caffeine can help improve the function of large arteries.

The participants in the study usually had no coffee drinking habits, ranging in age from 22 to 30. On the first day, the researchers

Everyone was asked to drink five ounces of coffee (about 142 grams), but the experiment was divided into two groups, and some people drank it.

Usually caffeinated coffee, others drink decaffeinated coffee, no one knows whether their coffee contains caffeine or not.

Then, the researchers measured the blood circulation of his fingers, blood pressure, heart rate, vascular impedance and other information.

We draw blood to analyze the concentration of caffeine in the blood and control the concentration of vascular functional hormones in order to figure out whether it is caffeine or Hall.

It plays a role. The experiment was done again two days later, and this time the two groups switched the types of coffee they drank.

The results showed that people who drank caffeinated coffee had a slight increase in blood pressure and improved vascular endothelial function.

There was no significant change in the heartbeat path with any kind of coffee. Professor Masahito Tsui pointed out that it is not yet known how caffeine works and changes.

Good vascular function, maybe caffeine can help open blood vessels and reduce the body's inflammatory response. If we can further confirm the effect of coffee

Coffee may be used to treat cardiovascular disease in the future.
