Too Much Caffeine Can Give Blood Sugar a Jolt

If you regularly have blood sugar fluctuations and consume a lot of caffeinated beverages (including diet soda, coffee, and tea), you should attempt cutting back to improve your glucose control.

Most people can safely consume up to 400 mg of caffeine per day, however, those who have diabetes may have low or high blood sugar due to caffeine's power to impact how insulin acts. About 200 milligrams of caffeine, or one to two 8-ounce (240 milliliters) cups of plain, brewed coffee, may have this effect in certain diabetics. Every person responds to caffeine differently. Limiting the quantity of caffeine in your diet may be beneficial if you have diabetes or are having trouble managing your blood sugar levels.
