Fry, bake, burn food and repeated use of high temperature cooking oil also contains carcinogens, should eat less as far as possible.

Low because of cancer deaths every year, a third is associated with poor diet, 30 many kinds of cancer

Low digestive system cancer, carcinoma associated with hormone levels, two types of cancer are influenced by dietary factors is the largest

Medical guide

The second people's hospital of guangdong province, chief physician, director of the general subject to the national security

"His destruction, food hygiene is true!

An unhealthy lifestyle, habits can lead to high blood pressure, diabetes and other chronic diseases, actually lifestyle especially improper diet more equivalent to cancer on this "dangerous train" added speed. Recently, there are news reports of dongguan man check-up every year, but still got cancer of the stomach.

According to the national cancer registry's latest research parsing oncosis spectrum in China "in 2014, according to if calculated according to the average life expectancy of 74 years old, people life cancer probability is 22%. Due to cancer each year one-third of all deaths related to poor eating habits, there are 30 kinds of cancer. Can prevent cancer, more is the day after tomorrow lifestyle and habits.

Medical experts pointed out that the most affected by dietary factors of cancer include two types: one kind is the digestive system cancer, including esophageal cancer, gastric cancer, colorectal cancer; Another kind is associated with hormone levels of cancer, breast cancer, endometrial cancer, ovarian cancer, prostate cancer, etc. It can be said that the cancer is likely to be related to diet, tube shut up, shut good eating, can simply and effectively prevent cancer, make a 40% lower risk of developing breast cancer.

As many as 970 kinds of carcinogens, anti-cancer food in four categories

Said to the national security, how to avoid eating out cancer, first of all should know what food is high carcinogenic substances.

The world health organization's international agency for research on cancer (iarc) "" dedicated to the research on classification of carcinogens, classify it into" carcinogen list ", by 2014, the list of "carcinogenic substance" has reached 970, the current in the diets of the 970 kinds of carcinogens in the specific cancer: tobacco, alcohol, aflatoxin, betel nut, Chinese style salted fish, etc.

Know a carcinogenic substance is the food, try to avoid in everyday life, can achieve lower cancer risk; At the same time, if moderate increase, the anti-cancer food in the diet may be the icing on the cake. There are more than one hundred common anti-cancer food, mainly divided into four categories.

First, there is fresh fruits and vegetables: with Onions, garlic, Chinese cabbage, cauliflower, represented by the white food has very good anti-cancer effects, which contain antioxidants, vitamin C, carotenoids, flavonoids and other active ingredients have anti-cancer effect.

The second type of bean products: bean curd, soya-bean milk is rich in soy isoflavones, often eat soy products can reduce the risk of breast cancer, colon cancer, prostate cancer.

The third class is fungi: about 96% of the bacteria have anti-cancer effects, such as dry mushrooms, mushrooms, needle mushroom, black fungus is rich in polysaccharide substance, can enhance human immunity, prevention of gastric cancer and lung cancer, the effect is better. At present, xianggu mushroom polysaccharide has been as anti-cancer drugs, for the treatment of tumor patients.

The fourth class of green tea: rich in polyphenols in green tea, can be combined with carcinogens, make its decomposition, inhibit the growth of cancer cells. Get into the habit of drink 2 ~ 3 cups of green tea every day, can prevent gastric cancer, liver cancer and lung cancer, but must pay attention to, tea is not too strong.

Possibly carcinogenic dietary factors

Salted fish produce dimethyl phosphite nitrates, pickled food in the body can be converted into dimethyl phosphite nitric acid amine carcinogens. Salted egg, brined vegetables also contain carcinogenic substance, should try to eat less.

Barbecue food roast beef, roast duck, lamb, roast goose, roast Suckling pig, kebabs, because contain strong carcinogens is unfavorable eat more.

Smoked foods such as bacon, smoked liver, smoked fish, smoked, smoked bean curd cake, egg contain benzopyrene carcinogen, often feed was susceptible to esophageal cancer and gastric cancer.

Fried food after Fried coke, generate carcinogenic polycyclic aromatic hydrocarbons.

Coffee after burning, benzopyrene increase 20 times.

Oil pancakes, stinky tofu, Fried taro Angle, and Fried dough sticks, etc, because most is to use repeated oil, high temperature will produce carcinogens.

Mildew food rice, wheat, beans, corn, peanuts and other food is easy to be affected with damp be affected with damp mildew, after mold contamination can produce a carcinogenic poison - of yellow aspergillus.

Overnight overnight food cooked cabbage and sour pickled cabbage can produce nitrite, will be transformed into nitrite amine carcinogens in the body.

Betel nut chewing is a cause of oral cancer.

Ten diet for cancer prevention principles

1. The diversification of food

Food is given priority to with plant food, should account for more than two-thirds of each meal, plant-based diet should be full of the fresh vegetables, fruits, legumes, and whole grains, the simplest approach is for the color, a day to eat five to seven kinds of color enough food is best.

2. The control of food intake and body weight

Japanese research shows that always eat too full, can reduce the activity of inhibiting cell cancerization factor, increase the risk of developing cancer. Avoid overweight or underweight, adult to limit weight gain no more than 5 kg, western fast food, sugar beverages are typically small in size but high heat food, after eating if you don't pay attention to sports, easy to cause obesity. Clinical study showed that 33% of the cancer in obese people. Being overweight or obese, easy to cause the risk of endometrial cancer, kidney, and increased risk of colorectal cancer. In addition, a good eating habits are very important, if eating timing quantitative, overeating, eating too fast too hot, to the injury of the esophagus and stomach is a stimulation, there is a certain relationship with esophageal cancer, gastric cancer.

3. Don't eat charred and smoked food

Avoid grilled fish, barbecue gravy is burnt. Directly on the fire roast meat, fish and bacon can only occasionally to eat. The fish and smoked meat contains large amounts of carcinogenic substances, such as 3-4 benzopyrene and pah. Fry, bake, burn food and repeated use of high temperature cooking oil also contains the carcinogen, should eat less as far as possible. Best boiled, steamed, Fried food.

4. Eat more starchy foods

Every day to eat 600 ~ 600 g various grains, beans, the type of plant roots, processing, the less the better. To limit the intake of refined sugar. The starch in food has the effect of prevention of colon and rectal cancer, high-fiber diet may prevent the occurrence of colon cancer, rectal cancer, breast cancer, pancreatic cancer.

5. Eat more fruits and vegetables

Every day to eat 400 g ~ 800 g all kinds of vegetables, fruits, can make the risk of cancer by 20%, a day to eat five or more than 5 kinds of vegetables and fruits.

6. Do not advocate drinking

Alcohol itself is not carcinogenic substance, but alcohol can stimulate the gastric mucosa, mucosal injury tissue, promote carcinogens absorption, if drinking smoking at the same time, the harm is greater. Because alcohol can enhance the permeability of the cell membrane, thus strengthen the uptake of carcinogens in the smoke. Such as regular drinking can increase the risk of oral cancer, laryngeal cancer, esophageal cancer, etc. Recommended drinking no more than one drink every day (equivalent to 250 ml, 100 ml beer wine or 25 ml of liquor).

7. Less red meat intake

Every day should be less than 90 g, it is best to instead of red meat, fish and poultry. Red meat may increase the risk of colon cancer and colorectal cancer risk. At the same time to limit high-fat diet, especially the intake of animal fat, should choose the right vegetable oil (such as olive oil, etc.).

8. Limit salt and spices

Pickles contain large amounts of nitrite and secondary amines, suitable acidity or under the action of bacteria in the stomach, can synthesize nitrosamine compounds, these compounds are strong carcinogenic substances. Preserved food restriction and control the use of salt and spices, high salt diet will increase the prevalence of gastric cancer. The world health organization recommends salt intake should be less than 6 g per person a day.

9. Don't eat food stored too long or mildew

Do not eat stored at room temperature for a long time, may be contaminated with mycotoxins food. In addition, daily life often encounter gone mouldy foods, mildew is caused by pollution of mold, mold some of enterotoxigenic fungus, is a strong carcinogen, at the same time, some food under the effect of enterotoxigenic fungi produce large amounts of nitrite and secondary amines, after entering the body under certain conditions, but also synthetic compounds and carcinogenic nitrosamines.

10. Protect the health of water

Because of the contaminated water contains a variety of carcinogenic metal ions, so be sure to use regular tap water, rural areas to use well water as much as possible.

To national security reminder, once appear, the digestive system, chronic stomach burning pain, mild nausea, and appetite than usual decreases, and has the feeling of abdominal distension after a meal, should be timely to the hospital inspection and treatment, and actively prepare for cancer prevention and control measures.

Particularly recommended anti-cancer food

Increasing importance in cancer: melon, tung artemisia, barley and berries. Tansy, potatoes, thyme, chives, Oats, aromatic substance, mint, cucumber; Cruciferae (stem cabbage, broccoli); Solanaceae plant such as tomato, eggplant, pepper; Whole wheat, flax, brown rice; Citrus fruit, such as orange, lemon, orange; Onions, tea, turmeric; Carrots, celery; Soy and ginger; Cabbage; Garlic.
