does tea or coffee affect blood sugar
Unsweetened tea should not affect your blood sugar readings. Tea is an excellent option if you are concerned with your blood sugar levels. Pure tea is not likely to impact your blood sugar significantly, and some types of tea may even help improve your diabetes and blood sugar control.
The average U.S. adult consumes about two 8-ounce cups (474 milliliters) of coffee a day, which can contain around 280 milligrams of caffeine. For most young, healthy adults, caffeine doesn't appear to noticeably affect blood sugar (glucose) levels, and consumption up to 400 milligrams a day appears to be safe. Some studies suggest that drinking coffee, caffeinated and decaffeinated, may actually reduce your risk of developing diabetes.
