Vegetables contain varying levels of starch and fiber, two types of carbohydrates, as well as vitamins and minerals. Fiber is important in regulating digestion and lowers the risk of heart disease.
Starchy vegetables raise blood sugar levels as they are digested, but they also contain nutrients important to good health. Some examples of starchy vegetables include potatoes, corn, lima beans and peas. Non-starchy vegetables include greens, broccoli, cabbage, onions and tomatoes. An adult diet should contain 45 to 65 percent carbohydrates, including fruits and vegetables, states WebMD. For the most health benefits, the American Diabetes Association recommends eating vegetables without added sugar, salt or fat.
