Type I and Type II Diabetes

There are two different types of diabetes. Type I and Type II. Type I Diabetes is usually diagnosed in children and very young adults. Type I Diabetes differs from Type II in that a person with Type I Diabetes does not produce insulin at all. Insulin is needed to take sugar from the blood into the cells. Type I diabetes used to be called Juvenile Diabetes as it was diagnosed in children at early ages. The symptoms of Type I and Type II Diabetes are very similar. Frequent urination, frequent thirst, excessive hunger are three of the most common symptoms.

A person with Type I Diabetes must be on insulin for the rest of his or her life. This does not mean that they cannot lead a long, productive life. In fact, people who are diagnosed young in life become accustomed to the treatment and are generally more compliant than those who are diagnosed with Type II diabetes later in life and who tend to ignore many treatment options.

Years ago, a child who was diagnosed with Type I diabetes had to inject himself every day with insulin to remain alive. Today, however, insulin pumps are available that make daily injections a thing of the past. 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. 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. With the advent of the Glycemic Index as well as other medical studies, it became apparent that sweets were not the only foods to avoid. As a matter of fact, a baked potato, often seen as a nutritional substance, is actually more harmful than a candy bar.

Carbohydrates are the bane to diabetics. And this is the food group rated on the Glycemic Index. People with Type I and Type II diabetes must limit their intake of carbohydrates. Certain carbohydrates, those rated low on the Glycemic Index, can be taken in smaller quantities. Those on the high scale should be avoided at all cost.

People with Type II diabetes are generally diagnosed later in life. This condition often effects older people and those who are obese. The incidents of Type II diabetes has mirrored incidents of obesity in the United States and most in the medical community agree that there is a clear link to obesity and the development of this disease. People with Type II diabetes do not process enough insulin to break down the glucose in their system and cause their kidneys to work overtime in getting rid of the waste. While some people with Type II diabetes are prescribed insulin, most are started on a regiment of medication.

Physicians generally hope that by taking medication as prescribed, exercising, eating the right foods and monitoring their blood glucose levels, they can avoid the use of insulin. In many cases, patients are very successful at maintaining good blood sugar levels by modifying their diet, exercising and losing weight. Others who are not successful usually end up taking insulin.

As with both Type I and Type II diabetes, there are complications. These complications such as heart disease, nerve damage, kidney disease and skin disorders can be avoided if patients comply with the instructions of their physician, learn about their disease and do all they can to manage it. Diabetes is far from a death sentence. With proper maintenance, those with Type I and Type II diabetes can live long and happy lives.

How To Use The Glycemic Index

The glycemic index is a rating of carbohydrates that was developed in 1981 by Dr. David J. Jenkins of the University of Toronto. 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. 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. Even corn flakes are considered bad carbohydrates on the Glycemic Index. This can be valuable information for anyone who has just been diagnosed as a diabetic and wants to discover which foods are more beneficial. While most diabetics will be told to avoid carbs, avoiding carbohydrates all together is not often feasible. For someone who thinks a candy bar is way worse than white bread, the Glycemic Index can be a real eye opener and can be a great way how to use the Glycemic Index for someone who is trying to discover which carbohydrates are safer than others.

Another way on how to use the Glycemic Index is to learn which carbohydrates are better for those who are trying to either watch their carbohydrate intake or who are on a diabetic diet. Some foods, such as fruits and certain vegetables, are low on the glycemic index and take a longer time to absorb into the bloodstream, giving the body the benefit of the nutrients while allowing the body to expel the glucose in a more natural way. One caveat when it comes to fruits and vegetables is that baked potatoes are not considered in the low group in the Glycemic Index.

As a matter of fact, potatoes are one of the highest ranking foods in the Glycemic Index. People consume French fries throughout the world like they are going out of style. Not only are they high in fat and offer little protein, they are also very high in carbohydrates.

Intermediate carbohydrates in the Glycemic Index include foods with a rating from 56 to 69. These include candy bars, some brown rices and croissants. This an be invaluable news to someone who is learning to develop a diabetic diet but who is unaware of what foods rank high and rank low.

Most people may assume that a piece of white bread is way worse for a person with diabetes than a candy bar, but this is not true. By learning the different ratings and classifications on the Glycemic Index, a person who is watching their carbohydrates as well as their diabetic diet can learn some invaluable lessons and learn how to use the Glycemic Index to their advantage.

High Glycemic Foods

In 1981, Dr. David Jenkins of the University of Toronto came up with a ranking system for carbohydrates based upon how long it takes them to break down into the system. 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.

Other foods are rated high on the Glycemic Index. These foods currently have high ratings and raise the blood glucose level quickly. High glycemic foods can be beneficial for people who are recovering from high exertion or those suffering from hypoglycemia. People with Type I or Type II Diabetes should avoid high glycemic foods as they can play havoc with the insulin or medication they are taking.

Some examples of foods that considered high glycemic foods include corn flakes, white rices such as jasmine rice, white breads and baked potatoes. People who have diabetes, either Type I or Type II, should avoid these foods as much as possible.

Other foods that are high glycemic foods include those with large amounts of white refined sugar or white flour. One thing a doctor will tell a patient on how to avoid high glycemic foods is to avoid anything white. This includes white bread, pasta made with white flour and even cakes or sweets made with refined white sugar or white flour.

High glycemic foods tend to take a long time to digest in the system of a diabetic. The glucose, or sugar, stays in the blood because the system of a diabetic is unable to process the refine sugars and flours. The glucose stays in the blood and in the urine causing the diabetic to frequently urinate, experience thirst and hunger more than the average person and sweat profusely.

After a while, this takes its toll on the system of a diabetic. The kidneys begin to hurt because they are not functioning properly. This is one symptom that diabetics often present with when seeking a physician. They also get blood in their urine and, in the worst case scenario, they faint or enter into an episode of semi-consciousness, confusion which can even lead to a diabetic coma. In some instances, a diabetic coma can prove fatal.

People who have Type I and Type II diabetes should be very mindful of which foods have a high glycemic index and avoid these foods in their diet. With proper diet, medication or insulin and monitoring of blood sugars, diabetics can lead a normal lifespan.

Diabetes is not a death sentence at all. It is simply a condition that many people possess that does not allow their body to break down sugars and starches through their system so that they digest normally. Diabetes is harmful to an individual who does not follow the advice of their physician, does not consume a proper diet and does not monitor their blood glucose levels. People who adhere to the medical guidelines concerning diabetes have just as much of a chance of living a normal life as anyone else.

Good Gylcemic Foods

The Glycemic Index was discovered in 1981 and is the basis for many recently popular diets, including the South Beach Diet as well as others. The Glycemic Index determines how long certain carbohydrates take to break down and digest in the system. Those with a high rating, take the longest time to break down and do the most damage to the system of someone with diabetes. The good glycemic foods; that is, those with the lower rates, are more desirable not only for diabetics, but for those who are watching their carbohydrate intake through such diets as the South Beach Diet, they should also be aware of what the good glycemic foods are.

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,. While most diabetics are wise to avoid most, if not all carbohydrates, as these are what are the most difficult to digest and break down, certain carbohydrates are better than others for diabetics to consume.

Good glycemic foods tend to have a low score on the Glycemic Index that was developed in 1981 at the University of Toronto. Good glycemic foods are still carbohydrates, but make it easier for the diabetic to digest and are much healthier and preferable than those glycemic foods with high ratings on the Glycemic Index. Substitutions are available for foods that rate high on the Glycemic Index and are widely available in supermarkets and other food stores.

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. Other fruits and vegetables, however, are preferable than white rice, white bread, corn flakes and anything made with white refined sugar or flour.

Other good glycemic foods include wholegrain breads and pastas. If you or a loved one has Type I or Type II diabetes, you should switch to whole grain breads and pastas made from wheat flour. This can be tremendously helpful to anyone who wants to manage their glycemia as well as anyone who wants to follow such low carb diets. Basmati rice is also considered one of the good glycemic foods.

Often, it is not a matter of eliminating carbohydrates when one is using diet to control their diabetes, but understanding which carbohydrates rate high on the glycemic index. Diabetes is a disease that can be controlled by proper diet, monitoring one’s blood sugar and following doctor’s orders as far as medication.
