Nowadays, technology is more and more developed, but for cancer patients, surgery and radiotherapy and chemotherapy are still the most effective means. Recently, however, Lao He, who is 65 years old living in Daxigou, has a new idea - "starving" cancer cells. Three years ago, he suffered from nasopharyngeal cancer. After the operation, his condition was controlled. At the end of May this year, when the old doctor went to the hospital for review, the doctor found signs of recurrence at the lesion. "The condition is not serious. The doctor recommended radiotherapy." Knowing that the condition can be controlled, his son He Yang and his family have a little peace of mind. However, Lao He, who was originally scheduled to begin treatment in June, repented a few days before he was admitted to the hospital. "The side effects of radiotherapy are very big! I will try this method first, maybe it will be useful." Lao He shared a WeChat article in his circle of friends. The article introduced a method of "codone diet", saying "not only Can prevent cancer, but also anti-cancer." After seeing this article, the old is like a treasure, and then strictly enforced. According to the article, this type of diet is mainly to consume meat and vegetables every day, not to eat starch products such as rice noodles, as well as beans, milk and fruits. At first, I was not used to it. I always felt hungry after a while. My wife Liu Niang was afraid that his nutrition was uneven. He had a few arguments with him and he could not screw him. "Even the snacks he usually likes are not moving. After a week, Lao He still insisted, and has been dragging to the hospital to treat the disease. Liu Niangniang is more and more anxious and can only get things to the son who works in Chengdu. He Yang turned to the health post in his friend's circle and read it carefully. This is explained in the post: "Cell cancer cells cannot change the structure and function, and can not use the ketone body energy that the human body can use. They can only rely on carbohydrates and do not absorb carbohydrates, so they can 'starve' cancer cells." Subsequently, He Yang queried the "codone diet" on the Internet and found that many media have rumored that he can "anti-cancer". "I also specifically asked the nutrition experts in Chengdu to ask, and said that it is not reliable." He Yang said. He Yang sent these rumors of WeChat to his father, but he was angry. "You want me to take medicine and chemotherapy, you don't believe in science." Lao He pulled his son's WeChat from the family group. Retired out. He Yang is helpless. He can only go home by car every week to persuade him. However, after one month, the effect is very small. Every time he listens to his son, he will get angry. He even left the house and even left the house. Fear of quarreling makes Dad's disease more serious, and He Yang does not dare to be too tough. "You let me try for two months, then go check. If it doesn't work at that time, it is not too late to go to the hospital." Lao He put forward the conditions to his son. He Yang and his mother are extremely anxious. "Which cancer cell development is accurate, I don't know how to persuade him now." "The ketogenic diet" is too angry "net red". This is dangerous for cancer patients. "Ketogenic diet" began to be popular in 2016, and many online media and self-media have published articles on "codone diet" related to anti-cancer and weight loss. "The ketogenic diet" has even been used by many European and American stars. The way to lose weight. Many articles have cited the experience of an American grandfather: the old man is a weightlifter, he has cancer, he did not receive regular treatment, and he claims to cure cancer through the ketogenic diet. However, since 2017, many media have questioned this diet. Can the “ketogenic diet†really fight cancer? Feng Changyan, deputy director of the Nutrition Department of Chongqing Cancer Hospital, said that the theoretical basis of anti-cancer diet is that cancer cells grow by glucose. Under normal circumstances, carbohydrates are converted into glucose by absorption, and if the intake is insufficient, the supply of glucose is insufficient. At this time, it is necessary to use the ketone body to supply energy, but the cancer cells cannot be powered by the ketone body due to changes in structure and function. “This is the so-called “starved†cancer cell. However, so far, ketol therapy is still concentrated in animal experiments worldwide,†the current ketogenic diet has research on brain malignancy, prostate cancer and gastric cancer. It has proven effective, and other malignant tumor studies have not been reported. Moreover, the success of animal experiments, the direct application of a large probability on the human body is useless, and even side effects. "Feng Changyan said. On the other hand, in addition to the tumor itself, many cancer patients also have diabetes, hypertension, hyperlipidemia and other diseases, high risk of thrombosis, poor appetite, poor gastrointestinal function, etc., often can not tolerate high Fat ketogenic diet may even aggravate adverse reactions such as nausea, vomiting, fatigue, weakness, hypoglycemia, etc. "Online recipes are mostly aimed at anti-epileptic children, not suitable for adult cancer patients' diet and calorie intake. " Feng Changyan reminded that if there are metabolic problems such as porphyria disease, fatty acid mitochondrial transport disorder, and ketone body synthesis or utilization disorder in cancer patients, it is absolutely impossible to use ketogenic diet. If blindly try the ketogenic diet, only reduce the intake of staple foods in daily life. Insufficient intake of protein and fat often leads to serious substandard nutrients, and even lead to continuous weight loss, decreased resistance, poor quality of life, and intolerance to anti-tumor therapy. The risk is increasing. "At present, the methods for treating tumors are mainly surgery, radiotherapy, chemotherapy, and targeted drugs. The ketogenic diet can only be used as a supplementary treatment. It is not recommended for patients to develop their own ketogenic diet." The current ketogenic dietary indications recognized by the medical community include: 1. Refractory children with epilepsy. The most effective epilepsy syndromes are: severe infant myoclonic epilepsy, myoclonic dementia epilepsy; better epileptic syndrome: infantile spasm, tuberous sclerosis; effective epilepsy syndrome reported in the literature : Lafora disease, acquired epilepsy aphasia, subacute sclerosing panencephalitis; reported cases of effective diseases are: phosphofructokinase deficiency, type V glycogen, mitochondrial respiratory chain complex disease. 2. GLUT1 deficiency (glucose vector deficiency). 3. PDH deficiency (pyruvate dehydrogenase deficiency) pyruvate cannot be metabolized or acetyl-CoA causes severe developmental disorders and lactic acidosis. What is a ketone diet? The ketogenic diet is a dietary model characterized by high fat, very low carbohydrates and moderate amounts of protein. The choice of food is mainly fish, meat, eggs, natural oils, nuts, fresh vegetables, etc., do not eat rice, noodles, corn. , beans, milk, sugar and sugary fruits. "There are clinical statistics showing that the ketogenic diet is most effective in controlling the condition of children with refractory epilepsy."
