Most fast food offer little in the way of nutrition but are high in fat and carbohydrates. Another way how to prevent diabetes is to exercise. Exercising regularly improves blood sugar control. Because active muscles dispel glucose from blood quicker than non-exercised muscles, regular exercise can do wonders in staving off or preventing diabetes. While this often is the result of medication from diabetes, hypoglycemia has many different causes and can affect anyone. Those with this disorder present with low blood sugar. This can be temporary and easily fixed by protein or food. In some cases, people who have been fasting can develop low blood sugar. Some of the signs of retina damage from diabetes include blurry vision, flashing lights, dark spots in front of the eyes, pain in the eyes, or pressure and trouble with peripheral vision. If you have been diagnosed with diabetes and are experiencing any of these problems, see your ophthalmologist for a complete eye exam. People with diabetes that is uncontrolled often can injure their feet without feeling it. The injury may result in a blister or wound that will be slow to heal. The blister or wound becomes infected and the foot complications of diabetes begin. In addition to not having the proper nerve sensations in their feet, people with diabetes often develop very dry feet because the nerves that secrete oil into the feet no longer work. They are low on the glycemic index and tend to take a long time to break down in the body, giving the system plenty of time to absorb the sugars and eliminate them without causing too much damage to the body. Other good glycemic foods include whole wheat pastas and certain types of rice. There are many excellent whole wheat pastas on the market today that make a wonderful substitute for traditional pastas that are made from white flour. Type II Diabetes usually sets on later in life, although more younger people are being diagnosed every day with this disease. According to the American Diabetes Association, approximately 54 million people in the United States have pre diabetes. Pre diabetes is a condition in which the blood glucose levels are higher than normal but not high enough to be considered Type II diabetes.
