Fasting glucose (fasting blood glucose, FBG) â this test measures the level of glucose in the blood after fasting for at least 8 hours. 2-hour glucose tolerance test (GTT) â for this test, the person has a fasting glucose test done (see above), then drinks a 75-gram glucose drink. Another blood sample is drawn 2 hours after the glucose drink. This protocol challenges the person's body to process the glucose.
Researchers found a kind of insulin-and-blood-sugar roller-coaster scenario. Peopleâs blood sugar levels peaked higher if they got sucralose, rather than water, before the glucose challenge test. Insulin levels also climbed higher. And, a few hours into the test, at the lowest blood sugar point, sucralose consumption led to lower blood sugar levels than did water, which can set the stage for carb cravings.
