A recent study shows that patients with type 2 diabetes are lower in countries where people consume black tea. However, researchers must now prove its effectiveness on individuals.
After analyzing recorded in fifty countries data , an international team of researchers said they found a link between the prevalence of type 2 diabetes (non-insulin -dependent) and black tea consumption .
Although the study , published this week in the British Journal of Medicine, shows fewer cases of type 2 diabetes in countries where a lot of black tea is consumed as in Ireland, the UK and Turkey, scientists are not going to advocate the consumption of black tea to reduce the risk of developing the disease .
A study in perspective
They do not want to jump to conclusions . For example , researchers warn about the quality and consistency of the recorded data in fifty countries . They add that the results can be just at national level but wrong at the individual level .
The study analyzed data from tea sales in 2009 and figures from the World Health Organization (WHO) on the prevalence of diseases such as cancer and diabetes.
According to the study , Ireland has the highest black tea consumption (more than 2kg per person per year ) , followed by the United Kingdom and Turkey. And conversely South Korea , Brazil , China and Mexico are among the countries consuming the least.
In the end, however, their figures show a linear association between moderate levels of maturity onset diabetes and the consumption of this type of tea , and is in line with previous research, which had already concluded in this direction.
In 2009 , researchers showed that the polysaccharides , a type of complex carbohydrates that help to delay the absorption of glucose, were mostly found in black tea.
