Vegetables that are good for a diabetic include dark leafy green vegetables, such as kale and spinach, sweet potatoes and beans, according to the American Diabetes Association. These vegetables have a low glycemic index and provide key nutrients.
Diabetics should choose non-starchy vegetables as part of their diet, notes the American Diabetes Association. However, some vegetables that are high in starch, such as corn, beans and sweet potatoes, are considered good choices because of the nutritional value they provide. Some of the best non-starchy vegetables are asparagus, artichoke hearts, carrots, broccoli and cabbage. Onions, peas and peppers are also good choices.
It's always best to choose canned, fresh and frozen vegetables and vegetable juice that have no added sodium. Frozen or canned vegetables that come in sauces are higher in sodium and fat, and it's important to drain and rinse canned vegetables with added sodium and then cook the vegetables in fresh water to reduce the amount of sodium left on the vegetables. To ensure a healthy diet, everyone should eat three to five servings of vegetables per day. A serving is 1/2 cup of cooked vegetables or vegetable juice or 1 cup of raw vegetables, explains the American Diabetes Association.
