Caffeine may be linked to diabetes, according to a new research. Drinking caffeine may interfere with glucose metabolism. Before your put down your Starbucks for good, there maybe be an okay time of day to drink some coffee. Drinking coffee might reduce the risk of diabetes, but when it comes to reaping the health benefits of java, timing is everything. Coffee has long been associated with a lower risk of diabetes, but until recently, little was known about the specifics of the connection.
A new study of nearly 70,000 women without diabetes found that those who drank more than one cup of coffee at lunchtime were 34 percent less likely to develop type 2 diabetes than non-coffee drinkers. The research team, led by Dr. Daniela S. Sartorelli of the University of Sao Paulo, focused on a group of French women ages 41 to 72 who were enrolled in a large European nutrition study. The study took place over the course of 11 years and during that time, 1,415 participants developed type 2 diabetes. The women in the group who drank at least three cups of coffee a day were 27 percent less likely to develop the disease compared to women who drank no coffee at all. However, when the researchers examined the data more closely, they discovered that the specific timing of coffee intake was the factor associated with the protective effect: only those women who drank more than one cup of coffee every day at lunchtime reduced their risk of type 2 diabetes — by 34 percent — compared to women who drank no coffee at lunchtime.
The connection was found for both regular and decaffeinated coffee, served black, with or without sweeteners. However, no protective effect was observed with instant coffee or coffee taken with milk. The authors hypothesized that coffee’s protective effect may result in part from a compound called chlorogenic acid, which has been shown to improve insulin sensitivity in animals.
