Drinking four or more cups of caffeinated coffee a day significantly reduced the risk of developing type 2 diabetes in women with a history of gestational diabetes.
Women who experience diabetes during pregnancy, also known as gestational diabetes, are at increased risk of developing type 2 diabetes later in life. The risk is calculated to be 10 times higher for her compared to healthy women without gestational diabetes.
The question is how can pregnant women with gestational diabetes reduce their risk of developing type 2 diabetes? According to experts at the Global Center for Asian Women’s Health (GloW), drinking coffee regularly after pregnancy may lower your risk.
Previous studies have linked bioactive components in coffee, such as polyphenols, to a reduced risk of type 2 diabetes in the general population. GloW researchers investigated whether drinking coffee regularly could also benefit women with gestational diabetes.
Coffee consumption and type 2 diabetes risk
The research team was led by GloW Director Professor Cuilin Zhang, who is also Professor of Obstetrics and Gynecology at the Yong Loo Lin School of Medicine at the National University of Singapore (NUS Medicine). This study was conducted in collaboration with the Harvard TH Chan School of Public Health and the National Institutes of Health (NIH).
The study included more than 4,500 women with a history of gestational diabetes. They were followed for over 25 years to examine the association between long-term coffee consumption and subsequent type 2 diabetes risk.
They found that women who drank caffeinated coffee after pregnancy had a reduced risk of type 2 diabetes. 53% less likely to develop type 2 diabetes compared to those who never took The risk of type 2 diabetes was reduced by 10% for those who drank less than one drink per day and by 17% for those who drank 2-3 drinks per day.
Effects of decaffeinated coffee
However, no significant association was found between decaffeinated coffee and the risk of type 2 diabetes. Experts say it may be because relatively few women drank decaffeinated coffee.
Additionally, replacing artificial sweeteners and sugary drinks with caffeinated coffee also reduced type 2 diabetes.
Overall, this study suggests that drinking two to five cups of sugar and full/high-fat dairy-free caffeinated coffee a day may benefit certain populations, including those with gestational diabetes. The results were recently published in the American Journal of Clinical Nutrition.
