Now, "anti-cancer" has become a topic of concern to everyone, but how can we most effectively block "carcinogenic molecules" from our bodies?
A report published in the magazine " Nature-Communication " shows that diet adjustment can reduce the risk of cancer. It can be seen that cancer is closely related to diet, especially with the following ten words. Life Times combines authoritative research abroad and asks experts to teach you how to prevent cancer from your mouth.
sugar
Some people say that sugar "nourishes" cancer cells. Although this statement is not accurate, a high-sugar diet is indeed related to cancer. Swedish scientists have conducted a nine-year follow-up survey on 80,000 people and found that excessive intake of sugar, sweet drinks, jam and other foods can increase the risk of pancreatic cancer . Eating sugar will lead to a large amount of insulin secretion, impairing pancreatic islet function, and becoming one of the potential factors that induce pancreatic cancer.
. Researchers at the MD Anderson Cancer Center in the United States discovered earlier this year that intake of large amounts of sugar in a typical Western diet can increase the risk of breast cancer and cancer metastasis to the lungs.
The World Health Organization recommends that the daily sugar intake should be controlled within 50 grams, preferably not more than 25 grams.
接 5接
June 15, a new study released by the International Cancer Research Institute showed that overheating beverages (such as coffee, tea, etc.) may cause esophageal cancer. "Overheating" means that the temperature of the beverage is above 65℃. It should be noted that drinking coffee and tea itself will not cause cancer, but don’t drink it too hot.
Chinese people especially pay attention to "while hot" when eating, but overheated food can damage the esophageal mucosa. If this continues, the mucosa will be repeatedly damaged, which may cause chronic inflammation and thus increase the possibility of cancer. Epidemiological research has found that Chaoshan people who love to drink kung fu tea and boiled porridge, residents of Taihang Mountains who love to drink big bowls of hot porridge, and Kazakhs in Xinjiang who often drink boiled milk tea are all high-incidence people with esophageal cancer and gastric cardia cancer.
It is recommended not to eat hot food, do not drink boiled water and hot tea directly, it is best to let it cool down before drinking. Be careful when eating small buns, fried buns, etc. with fillings.
salt
salt and cancer also have a "relative" relationship. One of the main reasons is that gastric cancer is high in in Japan, which is because it consumes too much salt. Eating too salty will lead to chronic damage to the gastric mucosal barrier, which will increase susceptibility to carcinogens over time and lead to gastric cancer.
Foods should be light rather than salty. It is recommended that the total daily salt intake should be less than 6 grams. At the same time, pay attention to the "invisible salt" in the food, such as soy sauce, MSG, seasonings, etc., and use less. People with strong taste in the meal should eat more fruits rich in vitamin C, which can help block the synthesis of carcinogen nitrosome compounds.
Pickled
Dried fish, fish sauce, bacon, sausage, pickled vegetables and other pickled foods have unique flavors, but this type of food often contains a large amount of nitrate, which will be converted into nitrite in the stomach, and then combined with the amine in the food to form nitrite amine, which is extremely carcinogenic and will increase the chance of cancer in the stomach, intestines, pancreas and other digestive organs.
A report jointly published by the American Cancer Institute and the World Cancer Research Foundation shows that eating processed meat products such as bacon can increase the risk of lower abdomen cancer (such as colorectal cancer). Eating 50 grams of processed meat products per day (equivalent to a hot dog) will increase the risk of lower abdominal cancer by 18%. Most of these processed meats are made by pickling.
It is recommended to eat fresh vegetables and meat as much as possible to reduce the intake of pickled foods.
smoked
In summer, people love to eat grilled skewers more, and smoked foods such as bacon, smoked fish, ham, and dried tofu are also loved by the public. When smoked and roasted food is made, a large amount of polycyclic aromatic hydrocarbons will be produced when the fuel is not completely burned, which has different carcinogenic properties. The strong carcinogen is benzopyrene. Regularly eating smoked and roasted foods such as roast beef, roast duck, roast lamb, etc. can easily lead to esophageal cancer and stomach cancer.
In addition, grilled foods are mainly meat, and excessive intake of animal foods will affect intestinal metabolism and increase the risk of intestinal cancer.
oil
The "oil" here refers to high-fat foods on the one hand. A research report recently released by Nature magazine showed that obesity, high fat and high calorie diets are risk factors that cause a variety of cancers. A high-fat diet can drive a surge in the number of intestinal stem cells, allowing them to reproduce indefinitely and differentiate into other types of cells, which is prone to 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 frying. Especially the oil that is repeatedly fryed, there are more carcinogens in it.
alcohol
study shows that excessive drinking is closely related to liver cancer; people who often drink beer or other alcoholic beverages have a high incidence of colon cancer; and a latest report in the United States shows that people's risk of gastric cancer is positively correlated with alcohol consumption.
China Cancer Foundation recommends that men should not drink more than 20 to 30 grams of alcohol per day, and women should not drink more than 10 to 15 grams.
mold
Due to the humid weather or improper storage, peanuts, corn, rice, sorghum and other foods are easily damp, and are contaminated by molds and produce mycotoxins with carcinogenic effects. This toxin is one of the most carcinogenic substances known at present and is closely related to liver cancer.
suggests that everyone learn to store food reasonably to prevent moisture and mold.
smoke
Smoking can lead to cancer, cardiovascular diseases, respiratory diseases and other diseases. In addition to quitting smoking, the cigarettes here also include oil smoke.
Chinese people like to fry, fry, and fry high-temperature cooking methods, and they also need to be improved. They are prone to produce a large amount of oil smoke, which is mixed with a lot of carcinogens such as alkanes, as well as inhalable particulate matter similar to PM2.5, which will increase the risk of lung cancer.
recommends that you adopt healthy cooking methods such as steaming and cooking, avoid excessive oil temperature when cooking, control the heat and time, and turn on the range hood.
lazy
Many people are too lazy to cook and like to eat processed foods such as ham and sausages. Some people are used to eating outside. Doing so can easily lead to excessive oil and salt intake, which brings cancer risk. It is the norm for many people to heat up the meal and eat it just by doing, but leftovers often have the risk of carcinogen nitrite.
It is recommended to eat on time and in quantity, eat fresh food, and try not to eat leftovers. In addition, being too lazy to exercise can also increase cancer risk.
6 words prevent "cancer from entering from the mouth"
According to statistics, the time it takes for a mutant cell to grow into a malignant tumor has an average of more than 30 years. Perhaps inadvertently, a tiny living habit of yours is driving the formation of cancer cells. Professor He Yumin said that in life, you should remember six words: "coarse, light, miscellaneous, less, bad, and plain". Starting from childhood, you may be able to really prevent "cancer from entering from the mouth".
coarse coarse grains, miscellaneous grains, crude fiber foods
food lack of plant fiber is one of the important reasons for the increasing number of cancer in recent years. Plant fibers have the function of "cleaning the intestines". They can promote intestinal peristalsis, shorten the time when intestinal contents pass, reduce the possibility of carcinogens being absorbed by the human body, and especially prevent the occurrence of colorectal cancer. Coarse grains are also rich in trace elements such as calcium, magnesium, selenium and a variety of vitamins. Among them, selenium is an anti-cancer substance that can combine various carcinogens in the body and excrete them out of the body through the digestive tract.
1 is best arranged for dinner
. The frequency of normal people eating is appropriate once every two days, and people with "three highs" can eat twice a day.
2 Coarse and fine combinations can complement each other
Research has found that dietary combinations are most suitable for 6-point coarse grains and 4-point fine grains. From a nutritional point of view, instead of eating corn, millet, and soybeans alone, it is better to mix them in a ratio of 1:1:2. Meat and eggs are the best partners for coarse grains and can play a role in nutritional complementation.
3 Coarse grains should not be made in detail
No matter which kind of coarse grains, it is best to use steaming and boiling cooking methods such as less oil and salt. For example, millet, oats, coix seed, etc. are suitable for cooking porridge.
light low fat, light, less salt
Eat less high fat and animal protein foods, and take natural light fruits and vegetables, and appropriately control salt intake. The National Academy of Sciences report pointed out that among all the dietary components, fat is the closest relationship between cancer, especially breast cancer, colorectal cancer and prostate cancer.
There are also tips for eating less fat, such as choosing low-fat or skim-fat fresh milk, replacing some meat with soy products, removing the fried flour from the outer layer of the meat skin and fat meat, scraping off the butter from the cake, and replacing the frying method with steaming, roasting and braising during cooking.
The World Cancer Research Foundation has issued a cancer prevention advice, among which "eat more vegetables and eat less meat" has been widely recognized by cancer prevention experts. Experts recommend that for those who love to eat meat, the weekly intake of red meat should be less than 500 grams, and eat as little processed meat products as possible; it is best to limit the consumption of white meat to less than 50-100 grams per day, and only eat 2-4 times a week.
In addition, salt and salt-grained foods may increase the incidence of gastric cancer. It is best not to eat more than 5 grams of salt per person per day. Especially be careful about the "invisible salt" around you. For example, in supermarket food, potato chips and instant noodles have the highest salt content. When dining outside, dishes with high salt content also make you "unprepared" for braised dishes, stews, old duck soup, etc. that northerners love to eat.
vegetarian Eat more fresh vegetables and fruits
It has been confirmed that sufficient amount of fruit and vegetable fiber can prevent colorectal cancer and reduce the incidence of several types of cancers such as breast cancer and esophageal cancer.
Dr. Rachel Thompson, scientific project manager of the World Cancer Research Foundation, recommended several of the most effective anti-cancer fruits and vegetables: tomatoes can reduce the risk of prostate cancer; broccoli, cabbage and bean sprouts can reduce the chance of developing digestive system cancer; strawberries, onions, and garlic all contain ingredients that inhibit tumor growth.
USDA, American Cancer Society and the National Cancer Institute jointly recommend that children aged 6 should consume 5 servings of fresh fruits and vegetables (1 serving of vegetables is about 100 grams and about 150 grams of fruits and fruits). Children and women aged 6 to 13 should eat 7 servings of fruits and vegetables every day, and adolescents and adults over 13 should eat 9 servings of fruits and vegetables every day.
Miscellaneous recipes should be mixed and broad
In fact, preventing tumors does not require any magic medicine, nor does it require expensive medicinal materials. The key is to have a balanced diet, not picky about food, mix meat and vegetables, and avoid dry and hot foods or excessive cold foods. As long as the cooperation is good, colorful foods such as red, yellow, white, green, and black are all "anti-cancer drugs".
The American Cancer Research Association has made it clear that no single food can protect people from cancer. Although many studies have shown that some of the ingredients contained in plant foods, such as vitamins, minerals, polyphenols, flavonoids, etc., have a certain effect on fighting cancer, it is not just recommended that any specific anti-cancer food be recommended, but it is recommended that more than 2/3 of the foods in the recipe come from vegetables, fruits, whole grains and beans.
Low Food intake should be controlled
Total food intake and sugar, protein and fat intake should be controlled. A research result in Tokyo, Japan pointed out that eating too much will increase the risk of cancer. The researchers found that the former has a higher probability of cancer than those who "eat very full every meal" and "basically only eat 80% full." While overeating, if you still drink and smoke, it will make the body worse. Digestive system tumors such as esophageal cancer, gastric cancer, and pancreatic cancer are all related to this.
to only eat "eight-minute full", you might as well try the following tricks: start eating when you feel a little hungry, and eat each meal at a fixed time, so as to avoid eating more and faster after being too hungry; eat at least 20 minutes, because the brain will receive the signal of fullness after 20 minutes from the beginning of the meal; use a small spoon instead of chopsticks, chew more than 30 times per bite of rice to slow down; eat more coarse fiber and increase the feeling of fullness, such as beans, konjac, etc.; serve less at a time, or use a shallow plate and transparent tableware.
Rotten Try to cook and cook
Except for fresh fruits and vegetables, other foods should be cooked and cooked. An Italian study found that carotene, lycopene and lutein are not afraid of cooking at all, but rather protect the body from cancer cells than eating raw. Especially carrots, tomatoes, as well as broccoli and cruciferous vegetables, which are rich in carotenoids and .
Su Sosen of the British Food Research Centre said: "The carotenoids absorbed from raw carrots are about 3% to 4%. After they are cooked or mashed, the absorption of carotenoids can be increased by four or five times, and cooking can help dissolve." Taking broccoli as an example, heating to 60 degrees is ideal, which can maximize its anti-cancer activity and reduce the risk of esophageal cancer, gastric cancer, lung cancer, gallbladder cancer and skin cancer.
1 Tender and crispy vegetables are mostly raw
Vegetables with crispy texture and delicious texture may be eaten raw, but be sure to chew carefully to fully release the anti-cancer substances.
2 Appropriate heating to promote absorption
Dark green and orange-yellow vegetables are suitable for the absorption of carotenoids. Especially for those vegetables with a stronger texture, the nutritional and health care ingredients in them are difficult to fully release when eaten raw.
3 Avoid soaking for too long to damage cells
Do not soak too long when washing to avoid cell damage.
4 Heat for a short time to keep it crisp and tender
After cutting, put it in the pot and cook immediately. When heating and cooking, try to choose a short-term heating method, and immediately serve it after the severity of the vegetables to keep the crispy and tender feeling of the vegetables.
5 Steaming and frying to preserve anti-cancer substances
Steaming and frying methods are highly heat transfer efficient, and they will not lose the active ingredients in water. They can save more anti-cancer substances than boiling methods.

cancer
cancer is a disease of human cells. Our body is made up of countless cells. The body automatically reproduces new cells, allowing us to grow, replace old cells, or repair cells damaged by injuries. This mechanism is controlled by certain genes. But if the genes that control the mechanism are damaged, cancer will appear. These damages have a chance to happen throughout our lives, and a small number of people inherited damaged genes from their parents.
Normally, cells will divide and reproduce in an orderly manner. But once it loses control, it will continue to reproduce, accumulate into blocks in the body, becoming a "tumor". Tumors can be divided into benign and malignant. Malignant tumors are commonly known as cancer.
The cells of benign tumors will stop in their positions and will not spread to other parts of the body.
Malignant tumors contain cancer cells. When it first formed, it will stay on the original part, so it is called "carcinoma in situ". But if cancer cells are not treated, they will destroy surrounding tissues and spread to other organs, becoming aggressive cancer.
Cancer is afraid of high temperature
Cancer is a disease that can occur from head to toe, but the heart, splenary , and small intestine (duodenum) are organs with a lower chance of cancer. That is because although the heart is only 1/200 of its weight, it is responsible for providing 1/9 of its body temperature; the spleen is the place where red blood cells are concentrated (※Note: The function of the spleen is to destroy old red blood cells, separate the heme of the red blood cells from the iron, and the separated iron can be absorbed into the blood again), and it is also a high-temperature organ; the small intestine must be responsible for digestion and must be active frequently, so it will naturally be warm. From these facts, it can be seen that cancer does not easily occur in high-temperature organs.
Organs that are prone to cancer in the human body, such as the esophagus, lungs, stomach, large intestine, rectum, ovary, uterus... are all hollow organs in the middle. With hollow organs, fewer cells and more likely to drop in body temperature, so they are more likely to develop cancer. As for the breasts protrude outside the body, they are also organs with relatively low temperatures, so the incidence of breast cancer is also a higher.
Generally speaking, cancer is formed by a decrease in immunity, which is of course related to blood. It can also be said that its occurrence is closely related to poor blood circulation. Dongyang Medicine believes that "the source of all diseases comes from the blood of the organs", so the body will react with fever in order to burn and discharge waste from the body and make the blood clean. On a certain level, fever can actually improve immunity, and immunity is the operational ability of the white blood cells. In fact, as long as the body temperature rises by 1 degree, immunity can be increased by 5-6 times.
Once the body is cold, blood circulation will become worse, and the metabolism of cells in the body will become worse. For every 1 degree of body temperature drop, metabolism will be reduced by about 12%, and immunity will be reduced by 30%. Usually, the lowest body temperature in the human body is also the highest mortality rate. During the day, the lowest body temperature is between 3 and 5 a.m. This is also the time when the most likely to cause asthma, severe abdominal pain, ulcerative colitis, and other diseases.
Reasons for the low temperature of modern people. About 1/4 of the body temperature when the body is calm comes from muscles, but modern people do not walk as often as before, nor are they as diligent as before, so they began to use machines to replace hands cleaning and washing clothes. The result of this lack of exercise is a major reason for the decrease in body temperature.
