Drinking More Coffee May Lower Risk of Type-2 Diabetes
Type-2 diabetes often appears later in life and is often the result of eating unhealthy foods and not getting enough exercise. A recent Harvard study suggests, however, that drinking one and a half cups of coffee may reduce the risk of developing type-2 diabetes by as much as 11%.
Participants in the study included 48,464 women who took part in the Brigham and Women’s Hospital-based Nurses’ Health Study from 1986-2006, 47,510 women in the Nurses’ Health Study II (1991-2007) and 27,759 men in the Health Professionals Follow-up Study from 1986-2006.
All of the participants filled out food frequency questionnaires every four years. During the time periods of the studies, 7,269 people self-reported diagnoses of type-2 diabetes and they were given additional questionnaires.
After examining the data, the researchers determined that the people who increased their coffee consumption by more than one cup per day had an 11% lower risk of developing type-2 diabetes than those who did not change their coffee drinking habits. Additionally, those who decreased their coffee consumption by more than one cup per day increased their risk of developing type-2 diabetes by 17%.
This study was published online ahead of print on April 26, 2014, in the journal Diabetologia.
Previous studies have shown that coffee has a number of health benefits. These benefits are generally attributed to the powerful antioxidants found in coffee called polyphenols and include reducing the risk of developing diabetes, prostate cancer, cirrhosis and oral cavities.
