Some cancer patients have the notion that the better the nutrition, the faster the cancer will grow. Since cancer cells like nutrition so much, we might as well eat less nutritious food. Therefore, we have seen that many tumor patients are often skin and bones and extremely thin before their death, which is closely related to the excessive consumption caused by uncontrolled growth of tumor, insufficient nutrient intake of the body, abnormal metabolism of nutrients and increased nutrient loss. In fact, the first principle of diet against cancer is to emphasize food diversity. Moderate and reasonable nutrition for tumor patients is a powerful support for cancer treatment and recovery. Obtaining effective nutritional support can not only improve the success rate of surgery and reduce postoperative complications, but also enhance the body’s tolerance to radiotherapy and chemotherapy and improve the quality of survival of cancer patients. Of course, appropriate dietary contraindications for tumor patients are necessary, but they should be tailored to the specific situation and scientific diet. So, what are the dietary rules to enhance cancer resistance? Eat less and live one more day For stomach cancer, intestinal cancer and other patients, eating too well and too full can easily trigger their digestive disorders or even obstruction; intestinal cancer patients eat too much high protein and high fat food, easy to make the disease recur, which has been widely proved in the clinic. As for breast cancer and ovarian cancer patients, too full and too good diet can easily cause over-nutrition, overweight and rising estrogen level, which will lead to metastasis and recurrence and make treatment more difficult. As for liver cancer, especially pancreatic cancer patients, often overeating is the direct trigger for its development. Drink green tea of the year The main active ingredient in tea is tea polyphenol, which has the effects of lowering blood lipids, lowering blood sugar, anticancer, antimutagenic, antioxidant, antiseptic and anti-inflammatory. Tests have proved that tea is effective in treating radiation damage, protecting hematopoietic function and increasing the number of white blood cells. Its anti-cancer effects mainly include blocking the synthesis of nitrosamine carcinogens, interfering with the activation of carcinogens in vivo, scavenging free radicals, anti-mutagenesis, direct inhibition of tumor cells, and enhancement of the body’s immune function. Tea saponin content of tea is about 0.07%, with anti-cancer, sterilization and other effects. Japanese scientists have reported that mice drinking green tea and black tea extracts have chemopreventive effects on lung cancer and liver cancer. The smaller the amount of oil, the better It is recommended that the daily intake of cooking oil per person is between 25 and 30 grams. In addition, because each kind of cooking oil contains different proportions of various fatty acids, it is best to choose a variety of cooking oils (such as peanut oil, corn germ oil, soybean oil, sesame oil and walnut oil, etc.) with the use of a balanced nutrition for the human body. At the same time, should be appropriate with some high-end cooking oil, such as olive oil and camellia seed oil. They are rich in oleic acid, which has a positive effect on the prevention of cardiovascular disease, lowering the low-density lipoprotein in the blood and raising the high-density lipoprotein. Be coarse not fine, be miscellaneous not fine A large amount of scientific evidence reveals that eating more coarse grains, miscellaneous grains and crude fiber foods can reduce the incidence of chronic diseases such as diabetes and cancer; whole grains (i.e., coarse grains, brown rice, whole grains, etc.) are not as good as fine foods in terms of texture and are not easy to digest, but they have a high nutritional value. In addition to rich starch, they are also the main source of B vitamins, but also contains potassium, magnesium, calcium, phosphorus and other minerals and fat, protein, dietary fiber and other nutrients. The greater the proportion of these foods in the diet, the lower the risk of cancer.
