Your diet, now that you have diabetes, is much more work and far less fun than it used to be. You’ve adopted the moderation mantra with such abandon that you can’t remember what it feels like to be overly full. You monitor everything that you eat, taking note of how it affects your glucose levels and your weight. You keep your alcohol consumption, along with your fat and sugar intake to a minimum, and you’ve replaced all of your old vices with fruits and vegetables, a tasty yet not always satisfying substitution. The one thing that you have retained, that you have clung to with childish obstinacy, is your coffee. But now, they’re telling you that you have to give that up, too.
A study of ten individuals with type 2 diabetes found that consuming the equivalent of four cups of coffee, in comparison to consuming no caffeine, led to heightened glucose levels throughout the day. On average, levels rose by eight percent, but after dinner that number was significantly higher at 26 percent. Although a small study with limitations, the findings are enough to cause concern. Glucose levels are already high when you have diabetes; the last thing anyone wants to do is raise them even more. So what should you do?
You don’t have to cut out coffee or tea or soda or all forms of caffeine completely, but you should limit it. If you regularly drink an urn-ful, cut it down to a mug or two a day. Try giving it up – just for a little while – to see how your glucose levels are affected. If nothing happens, have a coffee party. Or, switch to decaf. Studies have actually found that decaf coffee can be beneficial to your health. You’ll still have your bubbling liquid but without the grievous glucose.
