Diabetics can quickly check the sugar level of vegetables online via the U.S. Department of Agriculture’s National Nutrient Database, as of 2015. This database contains nutritional information for more than 8,000 common foods, including vegetables.
To use the database, visitors simply enter search terms for the food being researched, notes the USDA. For example, when searching for information on the sugar level of carrots, visitors enter that search term and are presented with options such as raw, dehydrated or canned carrots. By clicking on the link for raw carrots, a chart is pulled up that lists 5.21 grams of sugar per 1 cup of grated raw carrots.
Most nonstarchy vegetables can be consumed liberally and without worry on a diabetic diet, notes the American Diabetes Association. Nonstarchy vegetables have very low or no sugar, especially when they are fresh or frozen or when canned without added sugar, fat or sodium. Most vegetables contain very few carbohydrates and have a low glycemic index value. Many nonstarchy vegetables have around 5 grams of carbohydrates in a 1-cup raw serving or half-cup cooked serving.
Some recommended nonstarchy vegetables include carrots, celery, broccoli, eggplant and mushrooms, advises the American Diabetes Association. Onions, cucumbers, baby corn, okra and collard greens are also good choices.
