The types of cancer most closely with the food?

Cancer causes more complex, with a variety of factors, here only talk about the relationship between diet.

Esophageal cancer: After investigation and research, has found the following points:

' a lack of vitamin A, vitamin C and vitamin E.

' the lack of certain trace elements such as molybdenum, zinc, magnesium, selenium and so on.

' 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, crude found in the 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.

' drink alcohol while smoking increases the incidence of esophageal cancer will be increased significantly.

Gastric Cancer: According to domestic and international epidemiological studies, the incidence of gastric cancer may be related to the following factors

' 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.

' 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.

' Xi eat preserved foods.

' 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.

' alcohol: Alcohol can damage the gastric mucosa, causing chronic gastritis. Alcohol can promote the absorption of carcinogens, damage and reduced liver detoxification function.

Liver: in our coastal areas, especially 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

' 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.

' hepatitis B virus infection: China population, about 10% of people had the hepatitis B virus infection, due to bad eating habits and food hygiene, hepatitis virus is mainly through diet and non-sterile utensils transmitted to healthy people The. - Some patients with chronic hepatitis, liver cancer will occur.

' 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.

' Alcohol: Alcohol significantly damage the liver, can lead to malnutrition, cirrhosis, on this basis, can develop into liver cancer.

Colon, rectal cancer:

' 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.

' inadequate dietary fiber: the diet of plant cellulose and more countries such as Africa, Finland, Japan, China, colon, rectal cancer incidence was significantly lower than European and American countries.

' 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.

Other cancers:

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.
