The effect of the glycemic index on the body can assist a person who is watching his or her carbohydrates, either due to diabetes or a diet, to determine which carbohydrates are more dangerous for their body than others. A person who has been diagnosed with diabetes should familiarize him or her self with the Glycemic Index as soon as possible. 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. 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. This concept was developed to help people who wanted to rank carbohydrates based upon how they affected the blood glucose levels. 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. A person with Type I diabetes, as is the case with those with Type II diabetes, has to watch their diet and avoid certain foods high in sugar and starch. In 1981, the Glycemic Index was developed at the University of Toronto that rated those foods diabetics should avoid on a scale system. Some foods were very high on the scale and took a longer time to process in the system, causing more strain on the kidneys and adverse affects on insulin. Years ago, insulin was derived from animals and injected by a needle. Patients often needed multiple insulin injections throughout the day. There were problems with the insulin derived from beef and pork and many patients developed a resistance to the insulin after a period of time. In 1977, modern technology in the treatment of diabetes took a giant leap as human insulin was cloned.
