By 1981, the medical community was discovering he effect of the glycemic index on the body not only pertaining to diabetics, but to others as well. The effect of the glycemic index on the body gave birth to some very popular low-carb diets such as The South Beach Diet and other diets that monitored carbohydrate ratings. Good glycemic foods tend to absorb slowly into the system, allowing the body to break down the refined sugars and starches so that the body can digest them properly. People with Type I and Type II diabetes have a difficult time digesting carbohydrates, particularly those that are high on the glycemic index, and this lack of proper digestion makes it difficult for the diabetic to expel glucose from their blood,. Some patients with Type I diabetes present with nausea, abdominal pain and an comatose state. Diabetic ketoacidosis is another term for a diabetic coma which can result when diabetes is undiagnosed or uncontrolled. A diabetic coma can result in death. Most people with diabetes have too much sugar in their blood. Exercising regularly improves blood sugar control. Because active muscles dispel glucose from blood quicker than non-exercised muscles, regular exercise can do wonders in staving off or preventing diabetes. In addition, regular exercise also helps to maintain stable weight, another factor in preventing obesity. 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. Other foods were low on the scale and digested at a slower pace. For years, it was commonly assumed that sweets were the cause of diabetes at that these were the only foods to avoid. 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.
