 2. Consume less carbohydrates. Whenever you eat carbs, your body converts them into glucose, which then raises your blood sugar levels. Recent study shows that many people who switched from the standard American diet to a low carb diet experienced dramatic improvement in their blood sugar levels. Some of them get a straight blood glucose line since they made the changes. 3. Eat plenty of fiber. Eating lots of fiber slows down the digestion of food, preventing a sudden surge in blood sugar after meals. This will help your body keep a steady and normal blood sugar level. 4. Eat foods rich in chromium and magnesium. Why? These minerals support insulin function, which regulates blood sugar levels and also reduces the risk of blood sugar problems.
