Drinking Black Tea Regularly might reduce the risk for Type 2 Diabetes
(Best Syndication News) - Researchers found that people in countries who drank black tea on a regular basis were at a reduced risk for developing type-2 diabetes. The study results were published in the online journal BMJ Open.
The researchers mined for information on black tea consumption rates in over 50 countries by using an independent market research firm to determine 2009 sales. Then they compared data from the World Health Organization (WHO) to determine the rates of respiratory, infectious, cardiovascular diseases, as well as cancer and diabetes rates.
The researchers found that Ireland consumed the most black tea with an average consumption of over 2 kg/per year per person. The UK and Turkey followed closely behind Ireland in black tea consumption. The countries that had the lowest amounts of black tea consumption were South Korea, Brazil, China, Morocco, and Mexico.
They used principal component analysis (PCA) to compare the tea consumption against the various health conditions. Only diabetes showed a reduced rate of occurrence among the countries that consumed the most black tea. Even more statistical analysis was used to confirm the associated type-2 diabetes risk reduction from drinking black tea.
The researchers caution that countries may vary their criteria for diagnosing type-2 diabetes. This study looked at the general population and not individuals to determine the risk factor. On an individual basis, another study would be needed to confirm if drinking black tea reduced the risk of type-2 diabetes. However, their population study adds to the growing evidence that drinking black tea is related to a reduced risk for developing type 2 diabetes.
The researchers explained that green tea does not have the same flavonoids. Black tea is created by fermenting green tea, and this fermentation process creates more complex floavonoids such as theaflavins and thearubigins.
