Black tea may ease blood pressure fluctuations
An Australian study suggests that black tea consumption may substantially reduce the rate of blood pressure variation. The article, published in the American Journal of Clinical Nutrition, claims that drinking three cups of black tea a day alters blood pressure variation by about 10 percent. A sudden fluctuation in blood pressure can be an early warning sign of a stroke or even heart disease. Furthermore, the study used a flavanoid-free caffeine-matched beverage in the control group, which means that the results do not stem from caffeine, but from another component in black tea. The positive results of drinking black tea were noticeable from the first day and continued over the course of the six-month study.
