Cabbage glycemic index (GI)
Cabbage is low in sugars, as most of the carbohydrate content of cabbage consists of dietary fiber. Because of this, the consumption of enough cabbage to calculate its glycemic index is exceedingly difficult.
Official sources have not yet calculated an exact number for the glycemic index of cabbages. However, it is assumed to be low.
It is known that cabbages can have beneficial, antidiabetic properties.
Cabbage consumption has been explored for glucose-lowering and insulin-sensitizing potential (1).
Animal testing has found that red cabbage improves the liver and kidney functions of diabetic rats (2).
Since cabbage is rich in fiber it is a good option to consume them with salads before meals in diabetics to reduce post-prandial glucose levels. Adding vinegar or lemon juice to it will have even better effects (3).
