Why are there more and more cancers? The doctor scolded: The four kinds of meat should have been blacked out long ago, but many people regard them as treasures
In recent years, more and more people around me have turned pale when talking about "cancer", because cancer is more and more happening to young people around them, which makes many people feel very sorry.
The occurrence of cancer itself is related to many factors, especially our diet. Because the incidence of gastric cancer, esophageal cancer, pancreatic cancer, etc. is getting higher and higher, which are closely related to people's unhealthy diet.
Why are there more and more cancers?
According to Xinhua, the World Health Organization defines cancer as a collective term for a group of diseases that can affect any part of the body, and its other terms are malignant tumors and neoplasms.
A defining feature of it is the rapid production of abnormal cells that grow beyond their usual boundaries and invade adjacent parts of the body and spread to other organs, the latter being called metastasis.
Cancer will become more common as the global population grows and life expectancy increases. According to the World Health Organization, the number of new cancer cases is expected to increase significantly in the next few decades, and by 2040, the number of new cancer cases worldwide will increase by nearly 50% compared with 2020.
Regarding what causes cancer, the National Cancer Institute states that cancer is a genetic disease -- caused by changes in the genes that control how our cells function.
Genetic mutations that lead to cancer can arise for a variety of reasons, such as errors in cell division, harmful environmental conditions such as chemicals in tobacco or damage to deoxyribonucleic acid (DNA) caused by the sun's ultraviolet rays, and parental inheritance.
The body normally automatically removes damaged cells before they become cancerous, but this ability decreases with age, which is part of the reason why cancer risk is higher later in life.
The doctor scolded: The four kinds of meat should have been blacked out long ago, but many people regard them as treasures
【1】Processed meat
Smoked sausage, ham, sausage, sausage, marinated beef, beef jerky, canned meat and other processed meats that we often eat will add salt, food additives, preservatives, etc. into the body, which will increase intestinal damage and induce cancer.
Because of the marinated flavor, we all like to eat these foods and buy them for a long time. For those who like to eat meat, there are bottles and jars of meat and beef jerky in the refrigerator.
When many people eat instant noodles, they always pair it with ham sausage, which feels very delicious, but eating this kind of food often is easier to increase digestion, and the burden on the system will also increase the risk of cancer.
【2】Fried
Deep-fried chicken legs, chicken nuggets, chicken wings, etc., although delicious, are not good for your health. After high-temperature treatment of fried meat, polycyclic aromatic hydrocarbons will be produced, among which benzopyrene has a strong exposure to cancer, which will increase the risk of gastric cancer, intestinal cancer and other digestive tract cancers, especially children should eat less.
Fried foods are basically fast food brands. Although these foods can enhance the feeling of fullness, they are very high in calories. Excessive intake of calories will increase the burden on the digestive system and lead to obesity.
Obesity itself is the culprit of many chronic diseases, and it is more likely to induce a variety of cancers. It is enough to eat fried food once in a while. If you eat it for a long time, the consequences will be disastrous.
【3】Smoked meat
The traditional smoking process will produce a variety of polycyclic aromatic hydrocarbons in the case of incomplete combustion, including strong carcinogens such as benzopyrene. Long-term exposure will increase the risk of illness.
Smoked meat is generally eaten in rural areas, and many families have a lot of smoked meat in reserve, which can also be used for sale. However, smoked food contains very high levels of carcinogens.
The meat itself will produce smoke during the smoking process, which will affect the human respiratory system. At the same time, it will also cause a variety of carcinogens in the smoke and increase the burden on the digestive system. It is recommended that you keep your mouth shut.
【4】"Zombie" meat
Zombie meat mainly refers to the meat that has been stored in the freezer for too long. If the meat is kept in the freezer for a long time, more bacteria and even parasites will grow, which is harmful to health.
If you eat expired and frozen pork for a long time, it will lead to a decrease in the body's immunity and increase the chance of cancer. Zombie meat is hard to chew, and the taste is particularly bad, but there is a lot of zombie meat in restaurants, and many people buy it at a low price.
If you eat zombies often, it will be difficult for the meat itself to obtain nutrients, and you may also ingest more harmful substances, which will increase the burden on the digestive system, which is very harmful to health and increase the risk of cancer.
How to prevent cancer? It is recommended to know in advance!
National level. Pass legislation, attach importance to prevention and control, improve the environment, and reduce air pollution.
Pay attention to the health education for all, and adopt different educational methods to improve people's concept of healthy life and physical fitness.
Quit smoking. Smoking or using tobacco in any way can cause cancer. 90% of lung cancers are caused by tobacco.
Prevent infection. The occurrence of cervical cancer, liver cancer, nasopharyngeal cancer, lymphoma and gastric cancer is related to infection.
Maintain a reasonable weight and waist circumference. Obese people are more likely to suffer from cancer than other groups.
Scientific exercise. Any kind of exercise can help reduce the risk of cancer. Exercise should be added to daily life to help prevent colorectal cancer, breast cancer and endometrial cancer.
Eat a reasonable diet, choose healthy food and beverages instead of high-fat, high-sugar and high-calorie foods. Also eat a variety of vegetables, fruits, whole grains and legumes, avoid processed meats, and limit foods high in salt.
Limit alcohol consumption. For cancer prevention, try not to drink alcohol. If you drink alcohol, you should limit your daily alcohol consumption.
Breastfeeding, breastfeeding helps mothers prevent breast cancer.
Balance mentality and mental health. Mental health is a good medicine to overcome diseases, and bad emotions may be a cancer-promoting agent.
Conduct regular physical examinations, through which abnormalities in the body and risk factors for cancer can be found through regular physical examinations, and the risk of cancer can be reduced by timely adjustment of treatment. In addition, regular physical examination can achieve early detection, early diagnosis and early treatment.
Treatment of precancerous lesions. For example, colon polyps are precancerous lesions of colon cancer. By removing polyps, the purpose of preventing colon cancer can be achieved.
