Introduction: Cancer cells are mutations in the body. Cells are the source of cancer. Compared with normal cells, cancer cells undergo abnormal differentiation during cell division due to the influence of carcinogens, including DNA differentiation. And RNA differentiation also leads to cell division and malignant development.
The division of cancer cells is not carried out according to the principle of 1:2 and 2:4, cancer cells are dividing There are no rules at all in the process, and it is extremely harmful to the body.

Factors of cancer
1. Physical factors:
Large doses of radiation and ultraviolet radiation may lead to squamous cell carcinoma of the skin; people who live in areas contaminated by radioactive substances for a long time are prone to leukemia and lung cancer; eating too hard and overheated food for a long time is prone to esophageal cancer.
2. Chemical factors:
The so-called chemical factors mean that a person’s long-term and high-dose exposure to chromium can cause lung cancer, nickel can cause lung and nose cancer, and arsenic can cause Skin cancer, liver cancer, cadmium element can induce prostate cancer, iron element, lead element, zinc element, sulfur element, molybdenum element can also cause cancer.
Cyclic hydrocarbons, such as soot and coal tar, contain cyclic hydrocarbons that can cause skin cancer, nitrate Ammonium compounds can be found in drinking water and food, which mainly induce gastric cancer, esophageal cancer, colon cancer, liver cancer, lung cancer and so on.
3. Biology Factors:
Some viruses may cause cancer under certain conditions, legumes, nuts , Cereals and vegetables contain a variety of molds, such as Fusarium, Alternaria, Aspergillus versicolor, and Aspergillus flavus.
Aflatoxin produced by Aspergillus flavus has very strong carcinogenicity and may induce liver cancer and gastric cancer through clinical findings It shows that the incidence of cholangiocarcinoma in patients with liver fluke is higher, and the incidence of rectal cancer and colon cancer in patients with schistosomiasis is higher.
4. Genetic factors:
Most genetic factors in tumorigenesis only increase the body’s tendency to develop tumors and susceptibility to carcinogens. Tumors that are truly directly inherited can be said to be rare of tumors.
5. Immune factors:
Congenital or acquired immunodeficiency can easily induce malignant tumors, such as patients with gamma protein deficiency are prone to leukemia and lymphoid hematopoietic system tumors, and malignant tumors in AIDS patients The incidence rate is significantly higher.

Drinking coffee for a long time not only damages nerves but also causes cancer? Share the results of the research and read the knowledge.
In fact, the claim that coffee causes cancer can be traced back to 2018 An article published by the Wall Street Journal, “Judge Rules California Coffee Mustmust have cancer warning labels”.
In 2010 a non-profit toxicology research organization sued coffee sellers arguing that coffee beans were The carcinogen “acrylamide” is produced during the roasting process.
However, Starbucks and other companies have failed to prove that coffee Whether the content of acrylamide in it reaches the acceptable range for humans, so the US court ruled that such products should be marked with a cancer warning label of “acrylamide”.
Acrylamide was listed by WHO as 2a5 in 1994, which means that there is enough evidence of carcinogenicity in animal practice, but not enough carcinogenicity in humans Evidence.
2005 Food of the United Nations The average acrylamide content in brewed coffee was found to be 13 (g/kg), and the highest content was 116 (g/kg); the average acrylamide content of coffee (roasted, ground and uncooked) The amide content is 288 (g/kg), and the maximum content is 1291 (g/kg).
Verify whether coffee is carcinogenic published in A “Safe dietary intake of acrylamide in humans” in “Food and Chemical Toxicology” estimated that the daily carcinogenic amount of acrylamide is about 2.6g/kg body weight.
< p data-track="76">According to the above calculation, an adult with a weight of 50 kg can only reach the critical dose of cancer if he consumes 10 kg of brewed coffee per day, that is to say, he drinks about 28 cups of 360 ml of coffee.
Most of the coffee we drink every day is Western-style, so it is difficult to reach the amount of carcinogenic to the body , so the statement that coffee causes cancer is too absolute and has been divorced from everyday reality.

The benefits of drinking coffee regularly
1. Refreshing
The energy consumed by the human body comes from the decomposition of adenosine phosphate, which will release adenosine. Whenever adenosine binds to the receptor, it will send a signal to the brain, indicating that it is sleepy. Drink it at this time Coffee can have a refreshing effect.
2. Maintain intestinal health< /p>
Our research team studied the correlation between caffeine intake and the colon, the composition and structure of the gut microbiota, so drinking Coffee is good for health. It can strengthen the metabolism of liver organs and reduce body fat. People who drink coffee regularly are younger and healthier.
3. Prevention of dementia
According to multiple studies showing that reduced caffeine intake is inversely associated with a reduced risk of Alzheimer’s disease, scholars believe that coffee may help It can prevent some neurodegenerative diseases, but the mechanism of coffee’s action needs further research.
4. Reduce Morbidity
Drinking coffee in moderation can reduce the prevalence Stimulating nerves relieves physical fatigue, and can effectively help blood vessels dilate, thereby reducing the risk of cardiovascular disease. Therefore, people who drink two cups of coffee a day can reduce the risk of respiratory diseases and have an effect on cancer prevention.
5. Reduce body fat rate
Healthy people may pay more attention to body fat This is inseparable from the figure. The body fat rate of coffee drinkers is slightly lower than that of non-coffee drinkers, which makes the body look more symmetrical and slender. Of course, drinking coffee cannot be used to lose weight.

6. People with nervousness, anxiety and high blood pressure should not drink coffee< /strong>
