Scientists examining data from 50 countries claim that drinking black tea can reduce the rate of type 2 diabetes.
According to the study published in the BMJ Open journal, an open-access medical publication, “this innovative study establishes a linear statistical correlation between high black tea consumption and low diabetes prevalence in the world.”
The Europe-based study authors add that the findings “establishing a strong correlation between a high BT consumption and low diabetes prevalence, can be considered to provide a contribution to existing studies conducted on tea consumption, diabetes and obesity.” The number of people suffering from diabetes is supposed to explode to 438 million by the year 2030.
Drinking black tea did not seem to have any affect on the prevention of other illnesses however, according to the data.
Researchers gathered data from Data Mining International about global black tea consumption and also analyzed information from the World Health Organization.
It turns out that of all the countries, Ireland drinks the most black tea, to the tune of about 4.5 pounds per person annually. The UK was in second place.
Green, rather than conventional black, tea seems to get the most attention these days for its purported health benefits. According to the Medical Express website, however, black tea can also provide significant advantages:
“Green tea turns into black tea during the fermentation process. Fermentation induces a range of complex flavonoids, such as thearubigins and theaflavins, which have also been attributed with several health benefits.”
The study authors cautioned that the data collection as well as the ability to properly diagnose diabetes are variable from country to country. With that in mind, follow-up studies will be necessary. The authors also backed away from any suggestion that low rates of black tea drinking could cause diabetes.
