Can caffeine in Coffee Health Coffee restore Heart Health?

Coffee seems to offer mysterious benefits of heart health, but doctors find it difficult to explain why. There is now a small new study in Japan

Caffeine in a cup of coffee can help your capillaries work better and relieve intense stress on your heart.

According to a study presented at the annual meeting of the American Heart Association, compared to decaffeinated coffee, a cup of caffeinated coffee can

Increase the amount of blood that flows through the capillaries to your fingertips by 30%. Dr. Masato Tsutsui, from the Department of Pharmacy at Okinawa Ryukyu University, said that these tiny blood

The tube regulates the difficulty of blood flow through the circulatory system and body tissues.

This article is aimed at 27 adults between the ages of 22 and 30 who drink coffee irregularly and invite them to drink 5 ounces of decaffeinated or caffeinated coffee respectively.

The blood flow between fingers was measured with a non-invasive laser instrument. Two days later, drink a second cup of decaffeinated or caffeinated coffee

Neither the researchers nor the participants knew when they would drink caffeinated coffee. The study found that drinking caffeinated coffee

It will improve the blood flow of the capillaries by nearly 1/3, and the effect will last after 75 minutes. Although drinking caffeinated coffee slightly increases blood pressure

But the heart rate did not change in both groups.

Dr. Tsutsui said that the increase in blood flow may be due to an improvement in vascular intimal function, and the researchers linked the improvement in endothelial function to the future heart.

Visceral exhaustion, stroke, heart attack. Dr. Gordon Tomaselli of Johns Hopkins University School of Medicine says previous studies have shown

Coffee drinking is associated with a lower risk of heart disease, heart failure and stroke, and the researchers found that high doses of caffeine can improve larger arteries

But caffeine also increases blood pressure, and high blood pressure can damage arteries, and scientists don't know why.

Dr. Tomaselli, a former president of the American Heart Association, said it was an interesting finding that could help us understand why drinking coffee is beneficial. But...

How much coffee does it take to be effective? Dr. Tsutsui pointed out that research by the American Institutes of Health shows that drinking more than six cups of coffee a day can make

Men reduce their risk of early death by 10%; women reduce their risk of early death by 15%.

The study, published in the New England Journal of Medicine (New England Journal of Medicine), found that the more coffee you drink every day

The lower the risk. But because there are not many participants in this study, it is not possible to determine whether coffee is really good for the heart.
