Some of the best green vegetables for a diabetic to eat include spinach, broccoli and Brussels sprouts, according to Everyday Health and Diabetes Forecast. Diabetics should also eat cucumbers and asparagus. It's important for people with diabetes to eat plenty of vegetables to avoid raising their blood sugar.
Spinach is low in carbohydrates and a good source of beta carotene, iron, folate and vitamin K, notes Everyday Health. It's best to buy spinach that is either frozen or fresh rather than spinach that is canned. Spinach can be paired with an egg-white omelette or added to a salad.
Broccoli is a good source of iron, calcium, fiber, and vitamins C and D, states Everyday Health. The American Diabetic Association recommends that people with diabetes choose broccoli that's dark green and firmly packed together. Broccoli can be steamed or eaten raw, and it should be eaten as soon as possible after it has been bought.
Brussels sprouts are cholesterol free, a good source of fiber and low in salt, according to Diabetes Forecast. Some studies have also shown that Brussels sprouts contain special compounds that are beneficial to physical health. Sprouts can be boiled in water for 15 minutes before being roasted with salt, pepper and olive oil.
