If you love coffee and would like to drink more of it, there is some good news from the Harvard School of Public Health (HSPH). Researchers claim in a 2014 study that drinking more coffee can actually lower your risk of diabetes.
The study looked at 20 years of health and diet data for more than 100,000 people (a pretty convincing sample size) to determine if consuming caffeinated coffee and green tea could indeed affect type 2 diabetes. The researchers discovered that drinking an extra cup of coffee or two per day reduced a person’s chances of developing type 2 diabetes by 11 percent. Conversely, people who reduced their caffeine habits by drinking eight ounces less per day saw a 17-percent rise in type 2 diabetes. The stark difference between these two groups of people demonstrates pretty solid evidence that coffee consumption does indeed affect the risk of type 2 diabetes. Also, people who drink lots of coffee (24 ounces or more), according to the study, were 37 percent less likely to be diagnosed with type 2 diabetes than their non-coffee-drinking counterparts.
Unfortunately for you tea or decaf coffee drinkers, the study didn’t show any conclusive evidence that an increase in the consumption of these drinks would decrease your chances of developing the disease. But, other studies have shown that both of these beverages can help prevent the disease.
“Our findings confirm those of previous studies that showed that higher coffee consumption was associated with lower type 2 diabetes risk,” said Shilpa Bhupathiraju, lead author and research fellow in the Department of Nutrition at HSPH. “Most importantly, they provide new evidence that changes in coffee consumption habit can affect type 2 diabetes risk in a relatively short period of time.”
If you are looking for a magic number for your daily coffee intake, Bhupathiraju suggests somewhere between 3 to 5 cups per day.
