While it is good to eliminate the use of excessive sugar in your diet, carbohydrates are also contributory to the onset of diabetes. One way on how to prevent diabetes is becoming aware of the Glycemic Index. The Glycemic Index was developed in 1981 and rates which carbohydrates are more difficult to eliminate glucose from the blood. One thing a doctor will tell a patient on how to avoid high glycemic foods is to avoid anything white. This includes white bread, pasta made with white flour and even cakes or sweets made with refined white sugar or white flour. High glycemic foods tend to take a long time to digest in the system of a diabetic. Obesity is also an epidemic in the United States and many in the medical community believe that this is contributory to the corresponding diabetic epidemic. It is the general consensus of the medical community that obesity is a precursor to Type II diabetes. Therefore, those who have pre diabetes can stave off the disease by making some healthy life choices that will eliminate their need for medication or insulin in later years. Different carbohydrates are absorbed into the system in different manners and all take different times to break down and digest. Carbohydrates that break down and cause rapid digestion tend to leave the most glucose in the blood stream and cause the most damage to a person who is a diabetic. These carbohydrates are given a high rating on the Glycemic Index. Kidney Disease and Diabetes Not everyone who has diabetes gets kidney disease. This is yet another popular misconception about the illness. While uncontrolled glycemia can cause kidney disease, diabetics who maintain their proper blood glucose levels can avoid kidney disease. Diabetics who get kidney disease acquire this life threatening condition because they are unable to dispose of the waste products of sugars and starches through their systems. Precose did remarkably well in trial studies in breaking down the carbohydrates in the system, making it easier to eliminate. However, this medication has not done as well as the sulfonlureas, which are considered the best possible medications that treat diabetes at this time. However, for those who are allergic to sulfur, Precose is a good alternate.
