                                With a low glycemic index (GI) of approximately 15, raw rhubarb is surprisingly low on the glycemic scale for a food often associated with sugary desserts. This fact challenges the common misconception that this tart vegetable will cause a significant spike in blood sugar, as its glycemic impact depends almost entirely on how it's prepared.
