For centuries, Russian peasants sustained themselves on this leafy veggie. But even if your fridge is full of other foods, you should still consider eating cabbage. It's very low in calories (just 16 calories per 1/2 cup cooked) and high in fiber. Together, these two attributes spell weight loss, which should benefit your blood sugar. Add to that the fact that cabbage is way low on the GL scale, and you've got a Magic winner. And eating cabbage doesn't mean spooning up pale stew; if you prepare it right, cabbage can be a culinary delight.
This veggie doesn't just help you lose weight. Cabbage (especially the red variety) is also a surprisingly excellent source of vitamin C, which some experts believe may reduce the risk of developing diabetes. Red cabbage offers another bonus: It's rich in natural pigments called anthocyanins, which new research suggests may help boost insulin production and lower blood sugar levels.
Finally, cabbage is often prepared with vinegar, which can help lower the GL of your whole meal.
