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. 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. By maintaining your weight, following the instructions of your doctor and taking your medication, as well as watching your diet, you can eliminate the complications that often arise in someone with this condition. There are many ways you can control diabetes. Many people who are first diagnosed have a period of time where they are in denial. This means getting familiar with which foods should be avoided and which foods can be eaten sparingly. The Glycemic Index was established in 1981 to rate which carbohydrates are the worst for those with diabetes. The carbohydrates that are high on the list, such as white bread, take longer to digest and should be avoided. 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. The carbohydrates that are given a high rating on the Glycemic Index include those made with white sugar, white flour, baked potato, French fried pototoes, white break, pastas made with white flour.
