Radish glycemic index

Like most non-starchy vegetables, radishes are very low in carbohydrates. Because of this, calculating an exact number for the glycemic index of radishes is a difficult issue.

Radish roots are rich in dietary fiber and minerals, such as magnesium and zinc, which are obligatory cofactors for enzymes that improve glucose metabolism and insulin signaling pathways (3).

By enhancing the antioxidant defense mechanism, decreasing oxidative stress, improving hormone-induced glucose homeostasis, promoting glucose uptake and energy metabolism, and reducing glucose absorption in the intestines, radish roots have expressed significant antidiabetic properties and appear favorable in diabetic conditions (4).

However, the beneficial properties of food can change significantly based on the method of its use. Like so, Chinese radish cake, pan-fried and with plain rice flour, has a high glycemic index of 77 (5).

All in all, radish can be safely recommended for people with diabetes, as it's part of a healthy, balanced diet.
