This is because (1) drugs such as insulin, insulin proliferators and sensitizers just indiscriminately convert the sugars that patients eat into their bodies into energy. And in the case of excessive sugar intake by the patient, this energy can only be converted to fat. Because, the body glycogen capacity is very limited, while fat is almost the only way to store and compensate for the body after energy generation. Therefore, some patients will rapidly weight gain, and accompanied by rapid abnormalities of low-density lipoprotein, triglycerides, etc.; (2) α-glucosidase inhibitors only indiscriminately inhibit the breakdown and absorption of sugar, and biguanide hypoglycemic drugs also only indiscriminately transfer sugar to the surrounding and muscle tissue that the body’s normal basal metabolism can not use. In the case of patients with low sugar intake, such treatment will only aggravate nutritional metabolic disorders and accelerate diabetic complications. Because, the basic pathology of diabetes is impaired glucose metabolism, and the other side of high blood sugar and high urine sugar is precisely the insufficient nutritional capacity of sugar. The greater danger is that it gives false hope and leads the treatment of diabetes astray. The reason is that diabetes is not only a blood sugar problem, but also its own cause plus the series of nutritional and metabolic disorders it causes. For example, cardiovascular disease is not only seen in diabetes. Because of its underlying pathology: abnormal fat metabolism, which can be caused either by an inadequate dietary intake or by impaired glucose metabolism and the wrong application of hypoglycemic drugs. Because (1) excessive protein or sugar intake, the body automatically converts it into fat. The reason is that the human body has very limited capacity of free amino acid pool (one of the forms of protein substitution and storage) and glycogen (direct storage form of sugar), while fat is almost the only storage and substitution method of the human body after energy generation; (2) insufficient capacity of sugar (hyperglycemia, high urine sugar, too little dietary sugar, wrong application of α-glucosidase inhibitors, biguanide hypoglycemic drugs, etc.) the human body will automatically burn protein and fat instead. Because, breathing, heartbeat and other basic human metabolism and exercise, digestion and other basic human life activities required for energy can not be interrupted; (3) excessive fat intake, more directly raise blood lipids. And because fat is stored between the subcutaneous and tissue organs, while its metabolism is in the liver. Therefore, although not all of the above processes lead to dyslipidemia, too much fat running in the blood can lead to rapid hardening of blood vessels and eventually to cardiovascular disease. Not only that, but in fact other complications of diabetes are the same. For example, wounds that do not grow and infections that do not heal are also caused by insufficient sugar production, excessive protein consumption, and lack of raw materials for tissue repair and synthesis of immune substances in the body. Since protein cannot be synthesized in the body to meet the needs, it can only be consumed from a reasonable diet. Therefore, glucose-lowering treatment itself without a rational diet as a basis is one of the major causes of diabetes complications and remains so regardless of its technological development. This is because type 2 diabetics, who account for more than 90% of diabetes, all used to have very normal pancreatic islet function and a hundred times more powerful and scientific blood glucose regulation than doctors and their medications, but they still became diabetics. Why? The result of the cause of the disease. In other words, the culprit of high blood sugar is not diabetes, but the cause of diabetes. The key to treating diabetes is not to lower the sugar, but to stop raising the blood sugar. So, what is the cause of diabetes? Numerous medical studies have already concluded that the total energy of the diet is excessive and its composition of nutrients is not reasonable. So, can doctors and their glucose-lowering medications cure and effectively prevent the complications of diabetes? No matter how much hope anyone has, the objective reality is that it is not possible. Because the cause of the disease and the prerequisite for the use of drugs: diet is in the hands of the patient. Yet numerous medical studies have shown that most diabetic patients, however, have irregular diets and unstable postprandial blood glucose. They have even fallen into another, more harmful state of irrational diet. For example: vegetarianism, afraid to eat meat, etc.. And such a diet can only lead to insufficient protein, more frequent and hyperactive fat metabolism, more diseases such as cardiovascular and cerebrovascular and their complications instead more and appear faster. Because, the total energy is not enough patients will be hungry, and the lack of protein total energy can only be fat or sugar (starch decomposition is also sugar) overload. And no matter what fat, overload will be frequent vascular. Sugar overload is no different from fat, and all of them are saturated fatty acids. Because, fat is not consumed energy in the body almost the only way to store and compensate, and storage before processing into a low-density saturated state. Therefore, limiting fat at the expense of limiting high quality protein would not only not be useful, it would be extremely harmful. This is because the latest round of diabetes census results announced by the state on January 9, 2012 are realistic: there are currently 97 million people with diabetes in China, and the rate of good glycemic control in patients who have been seen is only 1/3. Meanwhile, several large evidence-based medical studies done in developed countries such as the United Kingdom and the United States that aim to prevent and reduce complications of diabetes through intensive glucose and lipid lowering have been unveiled in recent years. For example, ACCORD, an initiative funded by the National Heart, Lung, and Blood Institute to control cardiovascular risk in diabetes, UKPDS, ADVANCE, a study on the relationship between intensive glucose lowering and microvascular and macrovascular complications, and VADT, a veterans’ diabetes trial, all encountered the same problem: intensive glucose and lipid lowering was not effective in preventing and treating type 2 diabetes complications. type 2 diabetes complications. This is because the diet did not match their treatment, resulting in a significant increase in hypoglycemic events and mortality in their patients. In fact, this is true not only for diabetes, but for almost all diseases whenever dietary control is involved. For example, we currently have at least 200 million overweight people, 160 million hyperlipidemic patients, and a large number of hypoglycemic patients who will develop diabetes. This not only means that of the $40 billion in direct medical costs for diabetes and the hundreds of billions spent on treating complications of diabetes, nearly 70% is ineffective or excessive. It also means the inefficiency of a large number of advanced medical technologies and their drugs, as well as the enormous suffering of patients and their families and the huge burden it places on society. Because the complications of diabetes are brutal, especially cardiovascular complications, which are either fatal or disabling. Does this not require us to reflect?
