How Sweet It Is! Chocolate Improves Blood Flow
Want one more reason to relax your health-conscious attitude towards chocolate with the approach of the holidays? Japanese researchers say they’ve found dark chocolate to improve the body’s blood flow in healthy adults.
However, the researchers, who reported their findings at the American Heart Association’s recent annual meeting, said they found no such benefit when they tested white chocolate.
Chocolate, which is rich in flavonoids in its dark form, was used in both dark and white forms in the Chiba University study on 39 healthy adults, with an average of 29, who ate 550 milligrams of one of the other variety over a two-week period.
The study tracked what's known as coronary flow velocity reserve (CFVR), which is an indicator of the coronary arteries’ ability to dilate and allow more blood flow in response to administered medications.
Doppler echocardiography was used to measure CFVR at the start and end of the testing. Researchers also measured participants' blood pressure, blood lipids and two markers of oxidative stress, as a part of their approach.
After two weeks, those participants who ate dark chocolate showed significantly improved CFVR, but those who ate white chocolate showed no change, according to the study findings.
The Japanese team added, however, that because test participants realized whether they were eating dark or white chocolate, the results could have been affected, although it was not clear exactly what impact this could have made.
