Three or four cups of coffee or tea a day reduces the risk of diabetes.
People who drink the most coffee and tea, even non-caffeinated coffee and tea, can significantly reduce their risk of developing diabetes, researchers reported Monday.
Although the study does not explain the reason for this phenomenon, it still confirms previous similar findings. Previous studies have shown that coffee and tea may play a role in preventing type 2 diabetes.
The Huxley researchers Group at the University of Sydney in Australia published the report in the Archives of Internal Medicine. "drinking an extra cup of coffee a day reduces the additional risk of developing diabetes by 7%," they said in the report. "
The reason is not clear.
In other words, people who drank three to four cups of coffee or tea a day had a 25% lower risk of diabetes than those who did not drink these drinks at all or drank very little.
The team analyzed 18 different studies involving more than 450000 people and found this clear trend, but the reason is not clear.
"because most of the studies included in the analysis do not provide data on the effects of these drinks or their ingredients on hyperglycemia and insulin sensitivity, we have not been able to provide further evidence of mechanisms that reduce the risk of diabetes," their report said. "
Nor did they say whether those who drank more coffee ate less unhealthy food.
"our findings suggest that the protective effects of coffee and tea are unlikely simply because they contain caffeine," the researchers wrote. As long suspected, it is likely that a variety of chemicals in tea and coffee are at work. "
The result of this research is very meaningful. According to the International Diabetes Federation, there will be 380 million people with type 2 diabetes worldwide by 2025, mainly due to overeating and lack of exercise.
