Many people consume green tea, but not really know much about it. It is about time we learn something about green tea. This tea is a kind of tea made from the leaves of Camellia sinensis that haven’t undergone the same oxidation and withering process.
A process used to produce black teas and oolong teas. Moreover, green tea originated in China. However, its manufacture and production have spread to other countries in Asia.
There are several types of green tea and they differ according to the variety of Camellia sinensis used time or harvest, growing conditions, processing, horticultural methods, and production.
And there are the findings of one study which show that consuming green tea is linked with a raised risk of diabetes type 2 in Chinese adults.
In this study, a total of 119, 373 participants from SMHS, i.e. Shanghai Men’s Health Study and SWHS, i.e. Shanghai Women’s Health Study were included.
The SMHS and SWHS are 2 big population-based types of research that were initiated in the year 1996.
The findings from the studies have been used in order to investigate genetics and lifestyle risk factors for chronic diseases and cancer.
In this study, none of the participants had diabetes when enrolled. In this survey details of tea consuming including amounts and types were collected.
The researchers from research institutions, Vanderbilt University in the US, and Fudan University in China said that the participants in this study both male and female had raised the risk of diabetes type 2 if they consumed more green tea.
The researches noted that this dose-response and positive association between the risk of diabetes type 2 and the intake of green tea didn’t vary by smoking and obesity. The discovery has been reported in the International Journal of Epidemiology.
They said that there is a need for further studies on the mechanisms underlying the link, saying that maybe the pesticide residue in the leaves in tea might play a possible role.
All around the world green tea is a popular drink. In recent years, this drink has gained popularity as a healthy drink. However, the researches had had inconsistent discovery on the link between the risk of type 2 diabetes and tea drinking.
In 2006 a Japanese study was published in the Annals of Internal Medicine.
According to the study, frequent drinkers of green tea who drink around 6 cups on a daily basis had a 33 % lower risk for diabetes type 2 in comparison to those who consume 1 cup of less on a weekly basis.
A research done in the Republic of Korea was published in the Journal BioFactors in the year 2007.
According to the research people who have diabetes should consume less green tea because animal studies showed that a high intake of green tea might raise blood glucose levels in rats with diabetes.
