A new study has revealed that drinking green tea and coffee in a certain amount can reduce the risk of death among people who are suffering from type 2 diabetes. It is an observational study, which has been peer-reviewed. Scientists have observed around 4923 patients from Japan who have been dealing with type 2 diabetes. There have been 2790 men and 2133 women among the participants of the study. All the participants have been given questionnaires, which have consisted of 58 questions about their drinking and eating habits. This study has been published in the online journal of BMJ Open Diabetics Research and Care.
Experts have gathered data about the amount of green tea or coffee, participants have been consuming each day. Volunteers have been asked whether they exercise smoke or drink alcohol. Scientists have tracked the sleep pattern of each participant as well along with other lifestyle inquiries. Nearly 607 out of 4923 participants have said that they do not drink green tea at all. Around 1143 participants have reported that they drink only one cup of green tea in a day and 1384 people have said that they drink two to three cups of green tea in a day. Nearly 1784 volunteers have said that they end up drinking four or more cups in a day. Around 994 people have said that they do not drink coffee at all. 1306 people out of those who drink coffee have said that they drink up to one cup of the beverage daily. Around 1660 people have said that they have been drinking two or more cups of coffee every day. The participants have been tracked for more than five years. Over the period, nearly 309 people have died due to heart diseases and cancer.
The study has found that people who drink both or one of the beverages are at a lower risk of dying due to any of such causes. The reduced risk has been linked with drinking a higher amount of green tea and coffee. People who have been drinking at least one cup of green tea in a day are at a 15 percent lower risk of death. People who drink two or three cups of green tea have been at a 27 percent lower risk of death. Four and more cups of green tea have been linked to a 40 percent reduced risk of death. Coffee drinkers have also witnessed the same effect. The risk of death has been even less among the people who have been drinking coffee and green tea both. People, who have been suffering from type 2 diabetes, are at higher risk of dying due to dementia, bone fractures, cancer, and circulatory disease. The study has found that a higher amount of intake of green tea and coffee has been linked to a reduced rate of all kinds of mortality.
