The answer is:

1. Sugar ~ It is dangerous to exceed 25g per day.

Some people say that sugar will "nourish" cancer cells. Although this statement is not accurate, high-sugar diet is indeed related to cancer. Scientists have followed up 80,000 people for 9 years and found that excessive intake of sugar, sweet drinks, jam and other foods will increase the risk of pancreatic cancer.

Eating sugar will lead to a large amount of insulin secretion, damage the function of islet, and become one of the potential factors to induce pancreatic cancer. Researchers in The University of Texas MD Anderson Cancer Center, USA, found earlier this year that eating a lot of sugar in a typical western diet increases the risk of breast cancer and cancer metastasis to the lungs. The World Health Organization suggests that the daily sugar intake should be controlled within 50 grams, preferably not more than 25 grams.

2. Burn above 65 degrees is cancer temperature.

A new study released by the International Agency for Research on Cancer shows that drinks with a temperature higher than 65℃ (such as coffee and tea) may cause esophageal cancer. Overheated food can damage the esophageal mucosa. If you eat hot food for a long time, the mucosa will be repeatedly and chronically damaged, which may lead to chronic inflammation, thus increasing the possibility of cancer.

3. Fast food ~ eating 1 time, injury 1 time.

Many people are too lazy to cook, like to eat ham, sausages and other processed foods, and some people are used to eating out, which easily leads to excessive intake of oil and salt and cancer risk. It is normal for many people to eat their last meal hot and make do with it, but leftovers often have the risk of carcinogen nitrite.

Eat regularly and quantitatively, eat fresh food and try not to eat leftovers. In addition, lazy exercise will also increase the risk of cancer.

4. Excessive intake of pickled vegetables/meat ~ pickled products

Dried fish, fish sauce, bacon, sausage, pickles and other pickled foods have unique flavors, but these foods often contain a lot of nitrate, which will be converted into nitrite in the stomach, and then combined with the amine in the food to form ammonium nitrite, which has strong carcinogenicity and will increase the probability of canceration of digestive organs such as stomach, intestine and pancreas.

Eating 50 grams of processed meat products every day will increase the risk of abdominal cancer 18%. Most of these processed meats are made by pickling. Try to eat fresh vegetables and meat and reduce the intake of pickled food.

5. salty ~ too salty "fatal"

Salt seems to be the most dangerous seasoning. Eating too salty will lead to chronic damage to the gastric mucosal barrier, which will increase the susceptibility to carcinogens over time and lead to gastric cancer. People with heavy tastes can eat more fruits rich in vitamin C, which helps to block the synthesis of carcinogenic nitroso compounds.

6. Smoked food ~ contains strong carcinogens

Smoked food will produce a large number of polycyclic aromatic hydrocarbons, benzopyrene, a strong carcinogen, is one of them, which will cause cell mutation and cause cancer. Eat less smoked food.

7. Fry food in oil

How high-fat diet can drive the proliferation of intestinal stem cells, make them proliferate indefinitely and differentiate into other types of cells, which is easy to cause intestinal tumors. On the other hand, it refers to fried foods, such as fried dough sticks, oil cakes and stinky tofu, which often produce polycyclic aromatic hydrocarbons when fried. Especially the repeatedly fried oil contains more carcinogens. Eat less fried food, often add essential fatty acids and oils in the diet in a balanced way, and metabolize bad trans fatty acids and oils with good fats!

8. wine ~

Alcohol is the main carcinogen. Studies have shown that the risk of gastric cancer is positively related to the amount of alcohol consumed: excessive drinking is closely related to liver cancer, and the incidence of colon cancer is higher in people who regularly drink beer or other alcoholic beverages. If you drink regularly, it is suggested that men should drink no more than 20 ~ 30g and women should drink no more than10 ~15g every day. It is best to give up drinking. After all, alcohol is a primary carcinogen.

9. Moldy food ~

Of course, no one will deliberately eat food contaminated by mold. Peanuts, corn, rice, sorghum and other foods are easily affected by moisture, and then contaminated by mold, and sometimes it is not easy to be found, especially cold dishes in summer, and some moldy foods are invisible to the naked eye. In this case, food is likely to contain carcinogenic mycotoxins. For example, moldy melon seeds, peanuts and other nuts, moldy corn, peanuts and nuts will contain a lot of aflatoxin. Aflatoxin is a primary carcinogen, which mainly harms the liver. Long-term chronic liver poisoning can lead to cirrhosis or liver cancer.

10. lampblack ~

Cooking oil fume is easy to cause lung cancer. Chinese people use high-temperature cooking methods such as frying, frying and frying, but we don't know that this method is easy to produce a lot of oil smoke, which is mixed with alkanes, inhalable particles like PM2.5 and other carcinogens, which not only affects the skin, but also leads to lung cancer. A survey conducted by the Cancer Institute of Tongji University in Shanghai found that the risk of lung cancer among middle-aged and elderly women increased by 2-3 times due to long-term exposure to high-temperature fumes. According to the survey, among the risk factors of lung cancer among non-smoking women, more than 60% women have been exposed to kitchen fumes for a long time.

1, food diversification

Pay attention to the diversification of food, mainly plant food, each meal should account for more than 2/3. A plant-based diet should include fresh vegetables, fruits, beans and coarse grains.

Step 2 control your weight

Avoid being overweight or underweight, and limit the weight gain in adulthood to no more than 5 kg. Being overweight or obese can easily lead to an increased risk of endometrial cancer, renal cancer and intestinal cancer.

3. Don't eat burnt food

Avoid burning gravy when grilling grilled fish. Fish, meat and bacon barbecued directly on the fire can only be eaten occasionally. It is best to cook, steam and stir-fry food.

4. Eat more starchy foods.

Eat 600 ~ 800 grams of various cereals, beans and plant roots every day, and the less processing, the better. Limit the intake of refined sugar. Starch in food can prevent colon cancer and rectal cancer, and high fiber diet may prevent colon cancer, rectal cancer, breast cancer and pancreatic cancer.

5. Eat more vegetables and fruits.

Sticking to eating 400 ~ 800g of various fruits and vegetables every day can reduce the risk of cancer by 20%, and eating more than five kinds of fruits and vegetables every day.

6, do not advocate drinking

If you drink no more than one glass a day (equivalent to 250 ml of beer, 100 ml of red wine or 25 ml of white wine), regular drinking will increase the risk of oral cancer, laryngeal cancer and esophageal cancer.

7. Reduce the intake of red meat

It should be less than 90 grams per day, and it is best to use fish and poultry instead of red meat. Red meat increases the risk of colon and rectal cancer. At the same time, we should limit the intake of high-fat diet, especially animal fat, and choose appropriate vegetable oil (such as olive oil).

In life, it is most important to maintain a healthy and scientific diet pattern.
