1, fat, sweet, thick and greasy.
Fat, sweet and greasy products of traditional Chinese medicine belong to sweet and greasy food. From the clinical research, sweet foods, such as starch and sugar foods, can easily lead to gastric cancer if ingested excessively. Excessive intake of high-fat foods such as fat and oil can promote breast cancer, colon cancer, rectal cancer and pancreatic cancer. From the perspective of traditional Chinese medicine, tumor belongs to the category of accumulation syndrome. According to Neijing, accumulation syndrome is the stagnation of body fluid and blood stasis, and a fat diet is easy to help damp and produce phlegm, which will undoubtedly aggravate the coagulation of these pathological products.
From the point of view of modern medicine, eating a high-fat diet can make the liver secrete more bile. After entering the intestine, the primary bile acids in bile are transformed into deoxycholic acid and lithocholic acid under the action of intestinal anaerobic bacteria, and these two substances are cancer promoters, which can make the intestinal mucosa cancerous. At the same time, fat can also provide a suitable growth environment for a variety of tumors.
2, five flavors disorder
Chinese medicine believes that the diet should be mixed with five flavors, and the sweet, bitter, sour, pungent and salty foods should be eaten evenly. Any partial eclipse can lead to the occurrence of diseases. Among the factors causing tumors, too fat, too sweet and too greasy and too salty are common factors.
3, overeating warm food
The so-called warm food, first, refers to the food that is directly felt to be too hot and too hot; First, it refers to the warm sexual food that belongs to the division of traditional Chinese medicine. Because it is too pungent and hot, it is easy to damage the epithelial cells of digestive tract mucosa, so foods of this nature are most likely to induce tumors of digestive system.
Too hot diet is an important cause of digestive tract tumors such as esophageal cancer. Excessive diet will damage and stimulate esophageal mucosa epithelium, and will induce tissue malignant transformation under long-term stimulation. China people's digestive tract tumors are significantly higher than those of westerners, which is related to China people's preference for hot food and hot soup, such as vegetable soup and batter, for three meals a day. Compared with people in China, westerners have a simple diet, seldom have hot soup, but drink more cold drinks such as fruit juice and cola.
Alcohol is pungent and hot, and long-term drinking is the most common factor of digestive system tumors. Southwest Shandong is a high incidence area of esophageal cancer, which is related to the thermophilic and alcoholic diet in this area. In fact, as early as 1964, the World Health Organization believed that excessive consumption of alcoholic beverages was related to oral cancer, laryngeal cancer and esophageal cancer. In the investigation of Tongxing Township and Xining Township, which have relatively high incidence of liver cancer in Qidong County, Jiangsu Province, it is found that the mortality rate of liver cancer in the former is 2.5 times that of the latter. There is only one road between the two townships, the natural environment is basically the same, and the smoking rate is also quite the same. The difference is that people in high-incidence areas of liver cancer like to drink alcohol, while people in low-incidence areas like to drink tea.
Also belong to Chinese medicine hot food are fried and smoked foods, which become hot foods after being fried and baked at high temperature. Studies have confirmed that long-term consumption of such foods can easily lead to gastric cancer, intestinal cancer, liver cancer and so on.
Just as China people love tea, Westerners like to drink coffee. After five years of epidemiological investigation, American scholars believe that caffeine has certain influence on the formation of pancreatic cancer and bladder cancer. People who drink coffee regularly are 2-3 times more likely to develop these two cancers than those who don't drink coffee. At least half of pancreatic cancer patients are caused by drinking too much coffee.
4. Too salty
In addition to salt, salty foods include pickles, salted fish, bacon and other pickled foods. According to related research, the risk of esophageal cancer in people who often eat pickled food is 2.79 times that of people who don't often eat it. The most common cancer caused by eating salty food is gastric cancer. Gastric cancer and esophageal cancer are common among Japanese fishermen who are addicted to salted fish. Eating salted fish is also an important factor causing nasopharyngeal carcinoma. Malaysian researchers have found that coastal residents suffer from more nasopharyngeal carcinoma, which is related to their love of salted fish. China's census data prove that in areas with high incidence of gastric cancer, the average person takes 50 grams of salt every day; In the low incidence area of gastric cancer, the per capita salt intake is only about 6 grams.
In fact, salt itself does not cause cancer, and the cause of cancer is that high-concentration salt solution is easy to destroy the protective layer of gastric mucosa and cause mucosal erosion or ulcer. In this case, once it is invaded by carcinogens, it will cause local canceration of gastric mucosal cells. Salt is an indispensable substance for human body, but it should not be eaten in excess. It is generally believed that the salt intake of normal people should be controlled within 6 grams per day.
5. Degenerate and moldy food
Aflatoxin has been recognized as the strongest carcinogen, and Aspergillus flavus is rich in moldy grains, corn and peanuts, which is easy to grow and reproduce in warm and humid environment. Studies have found that it can induce various tumors in experimental animals. This factor is an important reason for the high incidence of cancer in some parts of Asia and Africa.
6. Pickled food
Nitrite is also a recognized carcinogen, and vegetables, fresh meat and so on will produce a lot of nitrite after pickling. Salted dried fish, fermented pickled vegetables, pickles and sauerkraut, cooked cabbage, sausage and meat overnight all contain nitroso compounds. If these foods are eaten frequently, there is a risk of cancer.
7. Four types of cancer have high genetic probability.
There are two manifestations of familial cancer, one is that many people suffer from different cancers, and the other is that there is a certain cancer aggregation phenomenon in a family. Although familial can explain that cancer is hereditary, it does not mean that everyone will be inherited. Most cancers are the result of the interaction of genetic and environmental factors, and the same living environment and habits make families prone to the same cancer. The following four kinds of malignant tumors have obvious genetic tendency:
1, colorectal cancer
There is a disease called familial adenomatous polyp, which can easily develop into intestinal cancer. It has been observed that if parents suffer from colon cancer caused by the above diseases in the family, the possibility of their children suffering from similar cancers is as high as 50%.
Characteristics of the disease: atavism
Precautions: colonoscopy should be performed 1 0 years earlier than the first patient in the family.
Ethnic polyposis coli has obvious familial aggregation, so if we want to avoid "hereditary" intestinal cancer, we must first check whether there are relatives in the family who have polyposis coli. Another feature of this disease is that it is passed from male to female.
If parents are diagnosed with familial polyposis coli at the age of 40, they should have diarrhea, abdominal pain, anemia, weight loss and intestinal obstruction before 10.
Therefore, the descendants of such patients should undergo colonoscopy 10 years in advance, and insist on doing it every year. It should be noted that the disease is atavism, which means that if the parents are not sick, it does not mean that the children are not sick.
2. Breast cancer
Women whose mothers or sisters have had breast cancer in their families are three times more likely to have breast cancer than ordinary women. Therefore, in addition to age, diet, obesity and other factors, breast cancer is also closely related to heredity. In addition, the heritability of bilateral breast cancer is obvious.
Characteristics of onset: young age
Precautions: Regular breast examination after the age of 30.
Normal women have regular breast health examinations every 1-2 years from the age of 35-40, such as mammography and B-ultrasound, but women with family history need to be about 30 years old in advance. Generally, B-ultrasound examination is the main method before the age of 35, and molybdenum mammography is performed after the age of 35, so as to find breast cancer at an early stage.
Moreover, women with genetic tendency should consciously carry out "breast self-examination" from the age of 20, especially after menstruation. If a lump is found in the breast with hard texture, poor mobility and no pain, they should go to the hospital early.
3. Retinoblastoma
Some retinoblastomas are also associated with genetic defects. This is a kind of malignant tumor, which is common in children. About13 of the patients have bilateral tumors, and all of them are dominant, which means that this disease has existed in a family for generations. The other 2/3 only occurs unilaterally, and about 10% of them are hereditary.
Precautions: prenatal diagnosis
Rb gene mutation detection has been successfully applied to clinical prenatal diagnosis. For the fetus of hereditary retinoblastoma family, amniotic fluid cells can be taken for Rb gene mutation detection at 28 ~ 30 weeks of pregnancy. If there is Rb gene mutation in this family, it is best to terminate the pregnancy. If the parents of the fetus are unwilling to terminate the pregnancy, they can go through the B-ultrasound examination of the female private parts at 33 ~ 35 weeks of pregnancy, once a week1~ 2 times, and observe whether there is a tumor in the eyes of the fetus. If the tumor has formed, they can induce labor at 35 weeks of pregnancy and immediately perform laser treatment on the tumor. It has been reported that retinoblastoma induced by labor and laser treatment at 35 weeks of pregnancy not only retains the eyeball, but also retains good vision.
4. Lung cancer
It has been reported that if a close relative has lung cancer and he smokes, his risk of lung cancer is four times higher than that of the general population/kloc-0. Japanese scholars have proved that 35.8% of patients with lung squamous cell carcinoma have a family history; Among female patients with alveolar cell carcinoma, the family history is as high as 58.3%.
Precautions: Good living habits
The mechanism of lung cancer caused by smoking has been clearly studied, and epidemiological data and a large number of animal experiments have completely proved that smoking is the number one killer of lung cancer.
There are also certain taboos in diet. Eat a diet with high protein, comprehensive nutrition, high vitamins, low fat and low salt, and avoid smoking and alcohol; Reduce the intake of spicy and irritating foods: onion, garlic, ginger, pepper, etc.; Eat less hot food such as frying and barbecue. You should eat some fresh vegetables and fruits rich in nutrition and vitamins.
