Understanding Glycemic Index and Glycemic Load
When we eat food that contains carbohydrate, then our digestive system changes carbohydrates into glucose which is then released into the blood hence called (blood sugar or Blood glucose).Glucose is the major source of energy for cells of our Body. The cells cannot take energy directly from the glucose.
On sensing the rise of glucose level in the blood, the beta cells of pancreas work to release insulin a hormone an essentially to enable cells of our body to take the glucose from the blood stream to transform into energy.
This is normal process of our body to get energy from food. Then question is why and what this Hallaballa (hue and cry) is all about GI and GL. Why we should all get to know G Index and G Load and Insulin Index.

Among Various measures to educate people to avoid obesity and diabetes, scientists advising people to know the carb contents in the food and for this purpose carbohydrate containing food they have indexed in three categories High, Medium, and Low Glycemic Index.The indexing of carbfood is in accordance with their carbohydrate contents and its effect on the blood glucose level.
Slowly absorbed carb foods which are slowly digested and converted into Glucose are in medium and low GI rating, while foods that are more quickly digested and transformed into glucose have a higher rating and are in High glycemic Index.
Glycemic Index Chart thus has been developed for the purpose of enabling people specially, obese and diabetic patient, to understand and chose carbohydrates, especially those which are slowly absorbed and converted into glucose in the digestive tract,
Glycemic Index uses a scale of 0 to 100,
• Low GI: 1 to 55
• Medium GI: 56 to 69

The supply of glucose to the brain and immune system is important as competitors constantly rely on instantaneous decision making to ensure they make effective strategic moves. Glucagon is the hormone which ultimately increases blood glucose concentration by breaking down stored glycogen in muscle and fat cells, increasing the breakdown of fats and increasing liver glucose production. Each of these effects lead to an increased amount of glucose present in the bloodstream, meaning more energy for body cells. When the level of glucose in the bloodstream drops, more glucose is required in order to provide ATP for energy. The secretion of insulin by beta cells is inhibited
Subject X’s reading result was 7.4 mmol/L. The results of a fasting test with respect to glucose levels in the body are: Normal: 3.9 to 5.5 mmol/l (70 to 100 mg/dl). Prediabetes or Impaired Glucose Tolerance: 5.6 to 7.0 mmol/l (101 to 126 mg/dl). Diagnosis of diabetes: more than 7.0 mmol/l (126 mg/dl).
FED UP In the US from since the turn of the century, obesity has been a rising and very serious issue. In the 1980’s, western culture experienced a fitness surge, and the major food corporations began producing new products that were “fat free”, but the issue was fat free food did not taste as good so people would not buy it. To compensate the taste, the food companies replaced the fat with sugar.
Why do we need it? Medical term of sugar is glucose, which we get from food and our liver. To make it easier to understand, glucose it a fuel needed to produce an energythat helps body tissues to build up our muscles. There is number of risk factors of diabetes already known for society, such as: family history, genetics, age, geography.
Did you know that one type of diabetes is much worse than the other? Type 1 diabetes causes your pancreas to stop making insulin, and insulin is needed to survive. Type 2 diabetes causes your body to become resistant to insulin. Diabetes is a serious disease that needs to be addressed by everyone. Making healthy food decisions and exercising can help lower the chance of getting type two diabetes or help people control it.
Type two diabetes can cause many issues and problems for the person involved. For example, one can develop kidney disease due to the fact that high levels of blood sugar make the kidneys filter too much blood. Waste products start to build up in the blood and eventually the kidney starts to fail. Secondly, diabetes can also cause amputations and blindness to occur in severe matters. The cause of nerve damage and poor circulation makes the feet and lower legs at risk of amputation.
When the body isn’t functioning correctly, the body begins to oppose the insulin. What the body does is it starts shutting down, preventing the body to process sugar as energy. The digestive system will only use what it needs, then it starts sending what’s left over to different muscles. This can actually slow down metabolism and raise blood sugar levels. Insulin resistance is a gateway to a lot of other diseases, or what we like to call Metabolic Syndrome.
Our bodies take in the glucose and turn it into energy we can then use. When we let glucose in, we are raising our insulin and glucose levels. Insulin is the hormone in people’s bodies that grants glucose access into our bloodstreams. However, insulin keeps our blood levels from raising or lowering, and it stores the fat to use for energy later on. Unfortunately, people have no control over the insulin function, though they do have control over the types of food they eat that contain certain amounts of glucose.
These two hormones help regulate plasma glucose, also referred to as blood glucose, levels. Glucagon increases blood glucose and Insulin decreases blood glucose levels. When blood glucose levels are too low, Glucagon sends a message for the glycogen to be broken down into glucose to be released into the blood.
The trick to making a gradual change is that when you go to the store, make it a point to purchase at least one thing from the glycemic index food list. Once you 've made a change - never go back to the old options. Sooner or later, everything in your diet will have a low glycemic index ranking. Now that we know WHAT to do to make the change in our diets, the
Background: In 2007, the Rio Grande Valley area doctors and business leaders formed an association called as the Rio Grande Valley Association of Diabetes (RGVAD) which aims to provide the awareness on diabetes to the residents from Hidalgo County. RGVAD provides programs and services that focus specifically for the areas in Hidalgo County and guarantees that all grants created by this association are used by the people or residents of the Rio Grande Valley region. In recent years, Diabetes has affect approximately 18 million people which is about 9% of the population in the United States. In addition, 13 million people have diabetes and which is unknown to people.
4. Glycemic index is classified into 3 different groups. Low, Medium and high. To classify these into the three categories one needs to look at the scale of the GI. Low GI is 0-55, medium GI is 56-69 and high GI is 70-100.
A Practical Guide to Dining Out You may be surprised by the variety of entrées available that are low on the glycemic index. Experiment with different salads, protein entrees and even sandwiches. Don’t be afraid of those sandwiches, as whole-grain and specialty breads are becoming ever more popular as the health food trend grows. More restaurants are now serving sourdough bread than ever before, and brown rice is becoming an increasingly popular option in Asian restaurants.
Sometimes, Fatima is invited to delicious meals in her daughter's houses which are a problem when adjusting her diet, as she likes to eat rice and bread when family gatherings are centered around meals. Foods high in carbohydrate content and calories may contribute to her lack of glycemic control. She enjoys being with
• Carbohydrate metabolism: • Gluconeogenesis: The formation of glucose from certain amino acids, lactate and glycerol. • Glycogenolysis: The formation of glucose from delglucógeno. • Glucogenosíntesis: The synthesis of glycogen from glucose. • Elimination of insulin and other hormones.
