Does black coffee affect blood sugar?

We are all different. If you are a young and healthy adult consuming up to 400 milligrams of caffeine a day appears to be safe. It doesn’t noticeably affect your blood sugar.

But, if you’re diabetic, just a single cup of coffee may see a blood sugar impact for some of us while others may be able to drink several cups without any blood sugar changes.

Caffeine is an addicting thing. If you're diabetics and must have your coffee fix,  some of the best options for your diabetic management are:

  • Avoid adding creamers, whipped cream, syrups, and sweeteners. 

  • Black coffee is strongly suggested for coffee drinkers with diabetes, as flavored creamers and sugar are high in sugar. You need to gradually adjust your tastebuds to appreciate the taste of black coffee, “Kopi-O-Kosong”

  • Cold-brew coffee is typically made with a higher ratio of coffee to water, and how coffee and water interact with one another, and how the flavors are extracted from the beans.

    It contains compounds including caffeine that may reduce your risk of heart disease, lower insulin sensitivity, stabilize blood sugar, and don't absorb as much sugar from your blood after you eat or drink. This causes your body to make more insulin, so you have higher levels after meals and lower blood pressure.
