| Preface Diabetes caused by insulin secretion defects and/or the role of insulin action defect, ,and its chanracteristic is chronic hyperglycemia with carbohydrate, fat and proteinaceous dysbolismus. TO display dipsesis,hyperdiuresis,visus ambiguity,weight decrease and polyphagia and so on, and when serious ketoacidosis or hyperosmolar state of ketosis, if the lack of effective treatment, can lead to stupor,cataphora even die. Diabetes t is global public health problem that threate mankind healthy and to wait for new method in precaution and theraphy. In the past 20 years, diabetes popular tendency was develop rapidly in most areas of the world,in spite of genetic factor of diabetes(especially type 2) wans important in etiological factor,but with continuous economy development and growing obesity problem is becoming a popular diabetes in some developing countries the main environmental factors. At present, there are at least 120 million people threatened by the type 2 diabetes of the world. It is estimated that the number of its incidence will increase to 220 million in 2010. Diabetes not only to consuming large amounts of funds in many countries, but also lose a lot of valuable resources and labor in many developing countries.About 10 years ago data estimate that the United States will have patients 14000000 with type 2 diabetes, and 300,000 patients died each year, public health expenditures amounted to 100 billion U.S. dollars.Domestic and intern- ational public health community have gradually realized from diabetes and its complications with the destruction of, such as retinopathy, nephropathy, neuropathy and cardiovascular diseases is essential for socio-economic and public health hazards caused by the enormous."Food" programme of treatment in patients with diabetes is the most challenging one of the factors. Diet of any diabetes treatment is effective, the most basic treatment. The medicine food combines, is a particularly light sufferer, through food control with regulate, usually don't need to take medicine or jot to take a medicine, the blood sugar urine sugar can immediately recover normally, symptom disappear.In patients with severe, the diet control and regulation, reducing medication, to a stable condition, reduce or prevent complications. Provide people are willing and able to adhere to, personalized and flexible dining plan more and more attention to nutrition workers.China's long-term residents to the main cereal food, dietary carbohydrate intake accounts for 60 percent of the total energy, food grains is to maintain the health of our people pillar, but also affect health, disease occurrence and development of the main dietary factors. Carbohydrate digestion and absorption quickly, most likely to affect blood glucose and insulin levels, this is the increase in diabetes, hypertension, coronary heart disease, obesity risk factors.Glycemic index is a measure of food-meal blood sugar response to a valid indicator, after digestion and absorption of food caused the blood-sugar changes reflect the true, especially for containing high-carbohydrate foods, the food can be a better description of Blood glucose in the body.GI in the prevention and control of certain chronic diseases has great value and strong operational, and people's awareness of carbohydrates to a new level.This study observed the impact of postprandial glucose by different GI food on patients with type 2 diabetes, to guide patients with diabetes reasonable choice carbohydrate foods.Method In patients with type 2 diabetes for the study. Patients were randomly selected 20 cases (diagnosed with type 2 diabetes, blood sugar stable) ,observation of the first day of the same object to ordinary moon cakes for breakfast the next day to a low GI moon cakes for breakfast. Blood glucose monitoring device in a dynamic 24-hour observation of dynamic changes in blood glucose, and fasting and postprandial 15 minutes, 30 minutes, 45 minutes, 60 minutes, 90 minutes and 120 minutes for blood sugar targets, two days before and after the quantitative observation Changes. Result The subjects were eating the same quality of carbohydrates / different dietary fiber content of cakes, both elevated blood sugar levels significantly different, low-GI moon cakes postprandial glucose was significantly lower than the ordinary moon cakes, the difference is statistically significant. (P<0.01)Conclusion Low-GI diet for postprandial glucose response, is a flexible and effective treatment methods. Can control postprandial hyperglycemia effectively, its mechanisms and low GI diet and insulin requirements relatively small, can help reduce pancreatic insulin secretion, reduce the burden on the pancreas and improve insulin resistance. Low GI food in the stomach stay long, slow digestion and absorption, glucose into the blood slowly ,increased peak low, slow decline, thereby avoiding postprandial hyperglycemia.This study will help patients with diabetes to carry out diet management, clinical and effective interventions for type 2 diabetes, and provide a theoretical basis. |
