Updated · ranked by glycemic index, lowest first · How we source our data
Short answer
The best vegetables for diabetes are non-starchy ones with a GI of 15 or below: methi (5), spinach (6), cabbage (10), bitter gourd, bottle gourd, ridge gourd, okra, brinjal, French beans, cauliflower and broccoli (all 15–20). They are also very light — bottle gourd and cucumber have about 15 kcal a serving. Keep starchy potato (GI 78), arbi and suran to small portions.
Fill at least half your plate with non-starchy vegetables at lunch and dinner, and keep starchy ones (potato, sweet potato, yam, raw banana) to smaller portions.

Which vegetables should diabetics limit?
Starchy vegetables like potato, sweet potato, yam (suran) and raw banana have a higher glycemic index, so diabetics should eat them in smaller portions and pair them with protein or fiber rather than avoiding them entirely.
