Some of the foods that rate low on the Glycemic Index include most fruits and vegetables, Although fruits and vegetables contain sugar, the sugars contained in these good glyceic foods digest into the system at a lower rate and also provide valuable nutrients to the diabetic, or just about everyone. The only vegetable that a diabetic should avoid is a potato, as it has a high glycemic index. Some carbohydrates break down very slowly and those release glucose gradually into the bloodstream and have a low glycemic index. For people who are diabetes, particularly those who are insulin dependent, a low glycemic index is preferable. These foods allow the insulin or medication to respond better to the blood glucose and allows for the sugars to break down more naturally. We often think of diabetics as being people with a sweet tooth who crave sugar. This is not the case. More often, a person who is obese has more of a chance of getting diabetes than a person who maintains his or her weight. One way how to prevent diabetes is by managing your weight. Although there is little you can do about having a genetic disposition to the disease, there are ways you can prevent becoming one of the millions of Americans who develop diabetes each year. This is the basics of kidney disease. Kidney disease is acquired in many ways. In diabetics, it is acquired because the kidneys worked too hard to filter out the sugars and starches and were unable to remove waste products from the blood. Eventually, like any organ that is overworked, they shut down. The name for eye complications of diabetes is called diabetic retinopathy. A person with diabetes should rely on a qualified ophthalmologist who is familiar with this condition. 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. 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. Today, insulin to treat diabetes is human insulin and is much more effective than insulin used in the past.
