One study found that decaffeinated coffee led to an acute rise in blood sugar, although the increase was smaller compared to caffeinated coffee. This suggests that while decaf coffee does impact glucose metabolism, it does so to a lesser extent. The exact mechanisms are not fully understood, but it is believed that other compounds in coffee, such as chlorogenic acids, might play a role in this effect. Chlorogenic acids are polyphenols found in coffee that are known to influence glucose absorption and metabolism. They may inhibit glucose absorption in the intestines and affect insulin sensitivity, contributing to coffee’s complex relationship with blood sugar regulation.
Interestingly, both caffeinated and decaffeinated coffee have been associated with a reduced risk of developing type 2 diabetes in the long term. This could be due to the presence of beneficial compounds in coffee that improve insulin sensitivity and glucose metabolism over time. Polyphenols, including chlorogenic acids, are thought to have antioxidant properties that reduce inflammation, potentially lowering the risk of insulin resistance, a precursor to type 2 diabetes.
For people with diabetes, it is still advisable to monitor how decaffeinated coffee affects their blood sugar levels individually. While it may be a safer alternative to regular coffee, its impact can vary from person to person. Consulting with a healthcare provider can help determine the best dietary choices for managing blood sugar levels effectively.
