                                According to glycemic index databases, fennel has a very low glycemic index (GI) of 15, indicating it is not likely to cause a significant increase in blood glucose levels. Far from spiking blood sugar, research suggests that various parts of the fennel plant may actually have a beneficial, hypoglycemic effect.
