More than 50% of the cancer and diet-related

Cancer has become second only to cardio-cerebral vascular diseases a serious threat to human health and disease, and everyone to talk about cancer, discoloration. According to scientists, statistics revealed that more than 50% of the cancers associated with diet and living habits, if we own these restaurants to avoid bad habits to overcome, perhaps we can reduce the incidence of many cancers.

WHO (1997) and the American Cancer Society (1996) confirmed that alcohol increases oral cancer, pharynx and esophagus and other parts of the risk of cancer. The long-term drinking can lead to cirrhosis of the liver, followed by liver cancer may be linked. Drinking alcoholic smokers can increase the risk of laryngeal cancer incidence.
　
Following types of cancer and diet-related factors:

1, esophageal cancer: According to the 2002 statistics of Beijing's eight areas the incidence of esophageal cancer in the fourth place in the countryside more.

① a lack of vitamin A, vitamin C and vitamin E.
② the lack of certain trace elements such as molybdenum, zinc, magnesium, selenium and so on.
③ eating pickled and moldy foods. Carcinogenic N-nitrosamines can cause a variety of cancers, which dimethylnitrosamine, diethylnitrosamine and methyl-benzyl-N-nitrosamines can be in the pickled meat and fish, rough-hewn found in fish sauce. In addition, Chen radish dry, Chen cornmeal, pickled cabbage and some moldy foods, and even sausages, beer is also more or less exists. Moldy foods, in addition to nitrosamines but also have mold toxins, the toxin itself can cause cancer, but also to carcinogenic nitrosamines synergistic effect.
④ drink alcohol while smoking increases the incidence of esophageal cancer will be increased significantly.

2, gastric cancer: According to the 2002 statistics of Beijing's eight areas the incidence of esophageal cancer in the third.
At home and abroad, according to epidemiological studies, the incidence of gastric cancer may be related to the following factors:
① delicious BBQ Food: BBQ food in the process will produce large amounts of polycyclic aromatic hydrocarbons compounds, which contain strong carcinogens such as benzopyrene, which permeable to the whole food. Curing process, the protein at high temperatures, especially in the scorched when the decomposition of carcinogenic ingredients.
② drinking water and food in the nitrate and nitrite content of high. The nitrate and nitrite in human stomach may be combined with amines to form nitrosamines, which is highly carcinogenic.
③ Xi eat preserved foods.
④ to eat moldy food, high incidence of gastric cancer found in the food and food contaminated by fungus and serious, even in the gastric juice in patients with gastric cancer, also detected mold and its toxins.
⑤ alcohol: Alcohol can damage the gastric mucosa, causing chronic gastritis. Alcohol can promote the absorption of carcinogens, damage and reduced liver detoxification function.



3, liver: According to the 2002 statistics of Beijing's eight region and the incidence of cancer in second place.
In China's coastal areas, particularly in the Yangtze River Delta and Pearl River Delta and other places the highest incidence. The occurrence of liver cancer and the relationship between diet is as follows:
① aflatoxin contamination of food: the geographical distribution of liver cancer in China and aflatoxin contamination consistent with the distribution of basic grain, oil, food by aflatoxin severely polluted areas, liver cancer incidence and mortality rates are high.
② water pollution: water pollution levels were positively correlated with liver cancer, suggesting that water pollution, carcinogenic promoter containing substances such as blue-green algae toxins, humic acid and so on.
③ Alcohol: Alcohol significantly damage the liver, can lead to malnutrition, cirrhosis, on this basis, can develop into liver cancer.

4, colon, rectum: According to the 2002 statistics of Beijing's eight region and the incidence of cancer of the fifth place.
① high-fat diet: eat high-fat diet group, the colon, the incidence of cancer than people eating low-fat diet high in animal experiments it has been confirmed.
② inadequate dietary fiber: the diet of plant cellulose number of African countries, colon, rectal cancer incidence was significantly lower than European and American countries.
③ Other factors: eat more foods rich in vitamin A can reduce the incidence of colorectal cancer, drink beer or other alcohol drank both beer crowd, the incidence of colorectal cancer is higher.



5, other cancer
A lot of information shows that high-fat diet with the high heat of the most positively correlated with the occurrence of breast cancer, lung cancer patients often lack vitamin A and selenium. There are reports that the high fat diet may be related to endometrial cancer, ovarian cancer, prostate cancer and the occurrence of gallbladder carcinoma. Laryngeal cancer, oral cancer and smoking, alcohol-related thyroid cancer in iodine-deficient diet-related nasopharyngeal cancer and diet of Central Asia and nitro-containing materials (such as nitrosamines) pollution.



Careful diet killer
As the saying goes: "disease from the mouth," the relationship between diet and disease in medical research have already been confirmed. Everyday we eat many things, it is a carcinogen which had been neglected, if not more careful, toxins accumulate, causing serious consequences are often difficult to predict.



Tea scale.Some people think that tea is tea scale deposition of the formation of a long-term, physical harm, very rarely go to wash, in fact, it is wrong. Tea scale contain cadmium, lead, mercury, arsenic and other toxic metals and certain cancer-causing substances, such as nitrite, etc., can lead to kidney, liver, gastrointestinal lesions occur in other organs.



　Part of the rotten fruit. Fruit rot, the micro-organisms in the metabolic process will produce a variety of harmful substances, in particular to accelerate the propagation of fungi. Some fungi have a carcinogenic effect in part through the juice from rotten to the non-decomposed part of the spread. So, although in addition to the decay part of the remaining fruit and still can not eat.



　Moldy rice, peanuts and corn. Which contain aflatoxin, which is the world recognized the strong carcinogens, easily lead to liver cancer and esophageal cancer. Some people think that more can be washed several times or high-temperature sterilization to remove toxic substances, in fact, aflatoxin contamination of food when it is difficult to completely removed.



　Alkaline foods MSG. MSG case of alkaline food will become glutamate, disodium to lose flavor; when it is heated to 120 ℃, it will become a cancer-causing substances sodium pyroglutamate. Therefore, there is soda, alkaline diet should not put MSG; soup, vegetables should be placed in the clean wok before MSG, avoid prolonged boiling.



　Charred fish and meat. Fish and meat fat inside the incomplete combustion, will produce a large number of V-aminomethyl derivatives, which is a strength of more than the carcinogen aflatoxin. Therefore, cooking fish and meat should pay attention to the furnace, once burned, never stop to eat.



　Rotten cabbage. Rot, and do not undercooked cabbage pickled in contain carcinogenic nitrites.



　Barbecue Food. All of the barbecue food, are prone to cancer-causing ability of a relatively strong material --- benzopyrene, which, and fried foods in the oil produced by repeated use of the same material
