Diabetes is a disease that is generally determined by the concentration of glucose in the blood. The amount of glucose in the blood is glycemia. The Glycemic Index indicates which carbohydrates have the highest levels of concentration of sugars and starches that make it so difficult for some diabetes to digest. Most diabetics have either Type I or Type II Diabetes. Generally, when a person is diagnosed with Type II diabetes, they are generally adults. Many people develop Type II Diabetes later in life after experiencing certain symptoms.
