If you have diabetes, your body’s ability to produce or use insulin is impaired. Insulin is a hormone made by your pancreas that clears the sugar you eat out of your blood and puts it into your cells so you can use it for energy. Starchy vegetables, including corn, contain carbohydrates that may raise your blood sugar, but they can be part of a healthy diet if you consume them in moderation.
Fitting Corn into a Healthy Diet
Even though you have diabetes, your meal plan should include small portions of carbohydrate foods, such as fruit, cereal, yogurt, beans and starchy vegetables. Corn is a source of energy, fiber, vitamins and minerals and is low in fat and sodium. Keep track of the carbohydrate grams you eat and set a limit for the day, advises the American Diabetes Association. A ½-cup serving of cooked corn or half of a large corn cob contains 15 grams of carbohydrate. Most people with diabetes should eat between 45 and 60 grams of carbohydrate per meal.
