I've been writing a good bit about coffee lately. That's because many of us enjoy having a cup (or several) regularly, and it turns out that coffee has a number of health benefits. I'm always happy to be able to encourage you to keep doing something you actually want to do. And, according to a new study, you may want to be particularly sure to maintain your coffee consumption if you're pre-diabetic.
This study was published in the Korean Journal of Family Medicine. So as you might expect from that title, it was conducted with Korean participants. However, I suspect that its results are relevant to those of us from different ethnic backgrounds as well.
For this study, the researchers examined data from nearly 3,500 pre-diabetic participants. Their glycated hemoglobin levels were 5.7% to 6.4%. The researchers wanted to determine if coffee consumption would slow the progression of diabetes in these patients. So they followed them for several years. And they used a number of analyses to try to isolate the impact of coffee and compare the coffee drinkers to control populations.

They found that the participants lowered their risk of diabetes progression the most by drinking three or more cups of black coffee a day. I know many people don't enjoy their coffee black. So you'll be pleased to know that there wasn't a significant difference in risk reduction for people who took their coffee with cream and sugar.
Of course, there's a difference between adding a little cream and sugar to a cup of coffee and adding heavy doses of flavored syrups or whipped cream. Don't interpret the results of this study as permission to indulge in what essentially amounts to a coffee-flavored milkshake on a regular basis. That will absolutely increase your risk of diabetes regardless of whether there's a little actual coffee in the drink.
However, if you stick with the more down-to-earth mix-ins that you can add in your kitchen (or you're perfectly happy with black coffee), go ahead and continue enjoying coffee as part of your morning routine. If you're pre-diabetic, this could be a great way to reduce your risk of developing full-blown diabetes. If you're not, it's still a great way to kick off your morning with an influx of antioxidants.
Yours for better health,
