Does caffeine affect blood sugar?
Caffeine is not favorable to insulin action. However, it doesn’t necessarily impair the blood sugar levels in young, healthy adults.
For people with Type 2 Diabetes, the effect of caffeine may cause a small but detectable rise in blood sugar levels, especially after meals. About 250 milligrams of caffeine per day can cause this result. So you had better limit the amount of caffeine in your diet.
