4. Blueberries
Blueberries truly stand out when it comes to being a diabetes superfood. The berries are made of insoluble and soluble fiber. The fibers help to flush fats out of your system. They also help to slow down the process of emptying your stomach while regulating blood sugar level at the same time.
In one study done by the USDA, it was found that people who consumed 2 ½ cups of wild blueberry juice each day were able to lower their blood sugar level, improve memory and reduce moodiness.
