Whether not eating can starve tumors Cancer is the number one public enemy of human beings and the cause of its development is still unclear, but research has found that 90%-95% of malignant tumors are related to external factors, among which diet accounts for 30%-35%, tobacco accounts for 25%-30%, obesity accounts for 10%-20% and alcohol accounts for 4%-6%. This shows that cancer is a nutrition, diet and lifestyle related disease. The claim of “starving tumor” is not reliable. Often patients come into the clinic and say to the doctor breathlessly, “I haven’t eaten properly for a long time” and “I want to starve my tumor to death”. In fact, there is no evidence that nutritional support can be used to treat tumors. In fact, there is no evidence that nutritional support can promote tumor growth. In the process of clinical treatment and patient recovery, even if no nutrition is given to patients, tumor cells will still plunder the nutrition of normal cells. If you want to starve tumor cells to death by not eating, only the patients themselves will be unlucky in the end. The incidence of malnutrition can be as high as 100% in patients with early stage of tumor, and in patients with progressive stage, especially in terminal stage. Nutritional support should be the basic treatment plan and measure for tumor patients to gain time for further surgery and radiotherapy. Then, it is necessary to figure out, “What should be eaten and what should not be eaten? What should be eaten more and what should be eaten less?” 57% of blood sugar will be consumed by tumor Cancer cells have a special taste for “sugar”. “Sugar” is carbohydrate – tumor tissues have increased glucose uptake and enhanced aerobic glycolysis. German biochemist and Nobel laureate Otto Warburg suggested that the biochemical characteristic of tumor cells is a shift from oxidative phosphorylation to aerobic enzymes, i.e. the Warburg effect. Compared with oxidative phosphorylation, glycolysis facilitates the rapid proliferation of tumor cells, which can obtain intermediate metabolites through glycolysis for the synthesis of lipids, proteins and nucleic acids to meet their active synthetic needs. In his book “How to prevent and treat cancer”, Dr. Nohji Nawa of Japan proposed the relationship between “sugar” and cancer. He said, “What is the energy source for tumor cells such as cancer cells to live? They do not rely on oxygen respiration as normal cells do, but mainly on glycolysis. These tumor cells have a very strong ability to break down sugar, about 20 times that of blood. If blood is made to flow through the tumor, about 57% of the blood sugar is consumed by the tumor. This shows how much cancer cells like sugar.” ”In 1977-1979, the World Organization for Economic Cooperation and Development conducted a special survey on sugar consumption and breast cancer incidence in 20 countries, and the results showed that those countries with high sugar consumption, such as the United Kingdom, the Netherlands, Ireland, Denmark and Canada, had high breast cancer incidence. The results showed that those countries with high sugar consumption, such as the United Kingdom, the Netherlands, Ireland, Denmark and Canada, have high incidence of breast cancer, while those with low sugar consumption, such as Italy, Spain, Portugal, Yugoslavia and Japan, have low incidence. The survey also found that the incidence of cancer was highest in older women aged 65-74 years, and that there was a greater risk for older women to eat more sugar, and that the amount of honey, syrup, raw fruit juice and glucose intake were all directly proportional to the incidence of breast cancer. Cancer patients should take more “eggs”. Tumor patients have abnormal protein metabolism and the body has negative nitrogen balance; tumor cells have increased protein synthesis; glutamine catabolism is enhanced, which is 10 times more than other amino acids; the body’s protein renewal rate increases. Cancer patients should eat more “eggs”, i.e. protein. Our recommended protein intake is (1.0-2.0) g/(kg/day). Patients can extract protein from natural diet such as meat, eggs, milk, etc., or mix two or more kinds of food to improve the nutritional value of dietary protein and supplement each other’s essential amino acid deficiency. When the natural diet cannot meet the demand, nutritional preparations should be supplemented in time, such as whey protein, which contains the amino acids required by the body, and its amino acid composition pattern is almost the same as that in skeletal muscle, which is easily absorbed by the body and has high utilization rate. ”Sugar” – carbohydrates are the main source of energy for the body, not a flood, potatoes, rice, corn, mixed beans, desserts, etc. are sources of carbohydrates. It is important to note that it is usually important to consume more quality carbohydrates that are good for health, such as whole grains and dietary fiber, and minimize the intake of desserts. Therefore, tumor patients should not be starving, but should have reasonable nutrition to overcome cancer, eat “sugar” appropriately and make up for “protein”!
