Drinking black coffee may raise blood sugar in diabetic patients.
The effect of coffee on blood glucose has not been fully clarified yet. Some short-term studies suggest that coffee consumption will raise blood glucose because it will raise the body’s adrenaline levels, which may increase blood glucose levels for a short period of time, but some long-term studies suggest that long-term coffee consumption may reduce the risk of developing type 2 diabetes mellitus.
In addition, there are individualized differences in sensitivity to coffee, and people with diabetes can drink black coffee according to their own circumstances. It is recommended that they monitor their blood glucose changes after drinking coffee to see how it affects them. If coffee can raise their blood sugar level, they can choose caffeine-free coffee.
It is recommended that diabetic patients eat and drink scientifically under the guidance of a doctor.
