The main kinds of carbohydrates are starches, sugars, and fiber. Learn which foods have carbohydrates. This will help with meal planning so that you can keep your blood sugar in your target range. Not all carbohydrates can be broken down and absorbed by your body. Foods with more non-digestable carbohydrates, or fiber, are less likely to increase your blood sugar out of your goal range. These include foods such as beans and whole grains.
Eat healthy foods. Plan meals that limit (not eliminate) foods that contain carbohydrates, which raise your blood sugar. Carbohydrates include starches, fruits, milk, yogurt, starchy vegetables (corn, peas, potatoes) and sweets. “Substitute more non-starchy vegetables into your meals to stay satisfied for fewer carbohydrates and calories,” Compston says.
There is convincing evidence that diets rich in whole grains protect against diabetes, whereas diets rich in refined carbohydrates lead to increased risk (53). In the Nurses’ Health Studies I and II, for example, researchers looked at the whole grain consumption of more than 160,000 women whose health and dietary habits were followed for up to 18 years. Women who averaged two to three servings of whole grains a day were 30 percent less likely to have developed type 2 diabetes than those who rarely ate whole grains. (21) When the researchers combined these results with those of several other large studies, they found that eating an extra 2 servings of whole grains a day decreased the risk of type 2 diabetes by 21 percent.
If you have type 2 diabetes and your body mass index (BMI) is greater than 35, you may be a candidate for weight-loss surgery (bariatric surgery). Dramatic improvements in blood sugar levels are often seen in people with type 2 diabetes after bariatric surgery, depending on the procedure performed. Surgeries that bypass a portion of the small intestine have more of an effect on blood sugar levels than do other weight-loss surgeries.
It’s best to get fiber from food. But if you can’t get enough, then taking fiber supplements can help. Examples include psyllium, methylcellulose, wheat dextrin, and calcium polycarbophil. If you take a fiber supplement, increase the amount you take slowly. This can help prevent gas and cramping. It’s also important to drink enough liquids when you increase your fiber intake.
