Tea contains antioxidants and anti-carcinogenic substances, such as catechins, which have health benefits such as preventing heart attacks and strokes and increasing survival after heart attacks and strokes. However, the relationship with type 2 diabetes, which is a typical lifestyle disease for modern people, was not well understood.
Although it is not that research has not been conducted, some studies have shown that it has a preventive effect on type 2 diabetes, and some studies have shown that it does not, and consistent results have not been obtained.
Therefore, a research team led by Xiaying Li of Wuhan University of Science and Technology, China, conducted a
As a result of the analysis, those who drink 1 to 3 cups of green tea, oolong tea, and black tea a day have a 4% risk of developing type 2 diabetes in 10 years, and those who drink 4 or more cups have a 17% risk. 'I found it was going down. There was a direct link between tea consumption and type 2 diabetes risk, with each cup of tea consumed per day reducing the risk by about 1%.
Regarding this result, Mr. Li emphasized that ``this study does not directly prove that drinking tea reduces the risk of type 2 diabetes,'' and added, ``This result suggests that drinking tea does not reduce the risk of type 2 diabetes. 'This suggests that high doses of four or more cups a day may be required to be beneficial in reducing the risk of type 2 diabetes.'
In fact, before conducting the above systematic review, the research team led by Li et al. also analyzed the results of a survey involving 5,199 Chinese participants. No difference in diabetes risk was found. In this survey, only participants were asked whether they drink tea, and data on the amount of tea they drank was not collected. is supported.
Regarding the reason why there was no significant difference in the Chinese study, Mr. Li said, ``Certain ingredients in tea, such as polyphenols , may lower blood sugar levels. It may be necessary to take enough of the active substance ,' he said.
Also, some experts point out that the habit of drinking tea may have led to avoidance of harmful drinks, rather than the ingestion of healthy substances by drinking tea. Professor Naveed Satar, who studies metabolic medicine at the University of Glasgow, UK, said, ``Rather than the ingredients in tea reducing the risk of type 2 diabetes, drinking tea makes you drink sugary drinks. I think the reason for this is the lack of opportunities,” he commented.
