Tea with stevia (1 piece)

Have the tea unsweetened or confirm that the stevia product contains no added sugar, dextrose, maltodextrin, or syrup-based fillers.

Avoid adding milk, creamers, flavored powders, honey, or sweetened plant milks; choose plain unsweetened milk or an unsweetened alternative if desired.

Try decaffeinated tea or a lower-caffeine variety, since caffeine can raise glucose for some people even without sugar.

Drink tea alongside a balanced meal or snack containing protein and fiber, such as plain Greek yogurt with berries or a small handful of nuts, rather than on an empty stomach.

Reduce the tea portion size or sip it more slowly, then compare your glucose response with your usual serving.

Check your glucose response on a few separate days and review the specific stevia brand and all tea ingredients to identify whether an additive or caffeine is the trigger.
