In 2011, it was estimated 8.3 percent of American population have diabetes, 90 percent of them suffer from type 2 diabetes.  While it may not require daily injection of insulin, type 2 diabetes mellitus is a risk factor to other big-ticket diseases such as heart diseases, strokes and renal failure. Now, it seems there’s a simple way to avoid type 2 diabetes, the subsequent complications and related diseases – a few cups of good ol’ Joe, every day.

Black Coffee

There are a few catches though; your coffees must be black, i.e. no sugar, artificial sweetener, creamers and even milk. You also need to have healthy Body Mass Index (BMI) which means several cups of coffee daily might not work as effectively on those who are overweight. You must be a non-smoker, exercise regularly and eat healthily too. If you are not, it’s high time to stop smoking, get your muscles moving and add more protein, vegetables and fruit in your diet. As for caffeinated or decaffeinated, it doesn’t matter.


The study in question was conducted for a period of 13 years on 400,000 adults around the age of 50 to 71. The researchers discovered every couple of cups of coffee, the risk of developing type 2 diabetes was down by 12 percent, (11 percent if they were 2 cups of decaf coffee) add another 2 cups and the percentage increased to around 22 to 24. We did mention a bit about the topic in our previous article; on how coffee apparently increases sex hormone-binding globulin (SHBG) that may improve body’s tolerance to glucose by boosting metabolism or improving its tolerance to insulin. For people with prediabetes, another study that ran for 8 years on 900 adults shown caffeinated coffee had mitigate risk of getting diabetes by 60 percent than those who didn’t drink coffee.


But, what if you already have type 2 diabetes? So far there are only just a few studies done on this matter. But it is advisable for you to shy away from caffeinated version. Caffeine will probably interact with your medication, rendering them ineffective. They also might spike the blood sugar level, postprandial. As for decaf, the effect is not conclusive. It depends on your body, if it can tolerate the coffee then it might be safe for you. Or you can opt for other hot beverages, like green tea or white tea just to be on the safe side.
