What are the "food assassins" in one cancer word and three mouths to stay away from?
An unhealthy diet increases the risk of cancer. Diet and nutrition may account for 20% of the global cancer burden; about 1/3 of human cancer deaths are attributed to diet, nutrition and other factors. At present, the number of cancer caused by diet is still on the rise. These five kinds of eating habits must be corrected according to the carcinogenic risk of the International Agency for Research on Cancer (IARC). After repeated high-temperature frying and fumigation, the carcinogen benzopyryl will be produced. Long-term inhalation or consumption of this kind of food is easy to cause lung cancer, liver cancer, bowel cancer, gastric cancer and so on. The nitrite contained in these foods is not carcinogenic in itself, and adequate heating and sterilization before eating can avoid carcinogens. Eating foods that are too hot (more than 65 ℃) often increases the risk of esophageal cancer. "drinks are also harmful studies have shown that active metabolites of alcohol (such as acetaldehyde) have carcinogenic effects. Heavy drinking may lead to a lack of certain nutrients in the diet. For foods that clearly contain carcinogens.
As we all know, cancer poses a major threat to human health and has become one of the important common health problems in the world. An unhealthy diet increases the risk of cancer, according to a report released by the World Cancer Research Fund. According to a large number of studies, 35% of 40% of cancers are related to unscientific and unreasonable dietary habits; diet and nutrition may account for 20% of the global cancer burden; and about 1/3 of human cancer deaths are attributed to diet, nutrition and other factors.
The occurrence and development of cancer are closely related to diet. at present, the number of cancers caused by diet is still on the rise. There are three mouthfuls of the word "cancer". Many cancers are eaten by people unconsciously.
Many cancers are eaten in one mouthful?
These five kinds of eating habits must be corrected.
The International Agency for Research on Cancer (IARC) classifies carcinogens into four categories according to their carcinogenic risk to humans. Among them, Class 1 carcinogen has the highest level, that is, it has definite carcinogenicity to human body, and there is conclusive evidence that it can increase the risk of cancer, followed by Class 2A carcinogens. These substances exist in all aspects of our diet.
1. Love frying and roasting? "Gourmet Trap" Don't be gluttonous
Such as Youtiao, French fries and barbecue, in repeated high-temperature frying, smoking will produce carcinogen benzopyryl, and the higher the temperature, the longer the time, the higher the paste, the higher the content. Long-term inhalation or consumption of this kind of food is easy to induce lung cancer, liver cancer, bowel cancer, gastric cancer and so on. In daily cooking, to avoid repeated heating of cooking oil, but also pay attention to grasp the temperature and time. Pay attention to ventilation, do not let lampblack gather.
two。 Moldy food should be "separated" in time, beware of "deadly killer" Aspergillus flavus
Such as moldy peanuts and corn, inferior peanut oil, metamorphic rice, etc., which contain aflatoxin, which can induce liver cancer, gastric cancer, colorectal cancer and so on. Therefore, to avoid eating moldy or suspected spoiled food. When eating bitter melon seeds, be sure to spit out and gargle in time, daily storage of food should pay attention to anti-mildew, keep dry and ventilated.
3. Can't resist the temptation of processed meat products and highly salted products? Keep your mouth shut even if you like to eat.
This kind of food taste and taste are very attractive, such as sausage, kimchi, salted fish, bacon, these foods contain nitrite itself does not cause cancer, but through the combination with biogenic amines in the stomach, the formation of carcinogen nitrosamines have carcinogenicity, mainly cause esophageal cancer, gastric cancer, liver cancer, colorectal cancer and so on. In addition, it should be emphasized that there is another misunderstanding, that is, people think that eating overnight food will cause cancer, but in fact, it is alarmist talk. Even if there is nitrite in overnight food, the content is far lower than the national standard of processed food. As long as it is properly preserved, adequate heating and sterilization before eating can avoid carcinogens.
4. The habit of hot food is very harmful, so don't eat it while it's hot.
Regular consumption of food that is too hot (more than 65 ℃) will increase the risk of esophageal cancer, and the esophageal mucosa will be damaged by long-term repeated high temperature, which can cause chronic inflammation and promote the occurrence of cancer.
5. Alcohol is very poisonous, and drinking also hurts the body.
Studies have shown that active metabolites of alcohol (such as acetaldehyde) have carcinogenic effect, which can cause oropharyngeal cancer, laryngeal cancer, esophageal cancer and so on. In addition, heavy drinking may lead to a lack of certain nutrients in the diet, making the tissue more sensitive to carcinogenesis.
In short, we must first have a correct understanding that food that clearly contains carcinogens does not mean that it cannot be eaten, nor does it mean that it will certainly lead to cancer. The carcinogenic ability of carcinogens is closely related to the dose. Only long-term excessive intake will increase the risk of cancer, but we should also be vigilant and pay attention to prevention in our daily diet.
Chronic inflammation is closely related to cancer.
How to prevent cancer through diet?
The World Health Organization (WHO) classifies cancer as a chronic disease, and clearly points out that one of them can be prevented, one can be cured by early detection, early diagnosis and early treatment, and one can not be cured, but it can be controlled by proper treatment to obtain a better quality of life and prolong survival. Cancer, which used to be considered an "incurable disease", is gradually evolving into a preventable and controllable "chronic disease".
Persistent chronic inflammation and oxidative stress have been proved to be closely related to the occurrence and development of cancer, such as colorectal cancer and colitis, liver cancer and chronic hepatitis. Inhibition of inflammatory reaction and oxidative stress can effectively reduce the occurrence of cancer and achieve a better cancer prevention effect. Changing dietary patterns to regulate inflammation and oxidative stress is one of the effective means to prevent cancer. Changing unhealthy eating behavior and choosing a reasonable and healthy diet can prevent the occurrence of cancer to a great extent.
1. Give priority to plant food and eat more dark vegetables
It is our clich é to "eat more vegetables", because it is rich in antioxidant and anti-inflammatory substances. For example, tomatoes and pomegranates are rich in lycopene to reduce the risk of prostate cancer; oranges, berries and peas are rich in vitamin C to prevent esophageal cancer; such as broccoli and spinach can prevent stomach cancer.
two。 With whole grains such as wheat, oats and corn
This kind of food is rich in dietary fiber, which can be combined with carcinogens, improve intestinal health, stimulate intestinal production of short-chain fatty acids, and prevent colorectal cancer. Data show that if you take 10g of dietary fiber from food every day, you can reduce the risk of colorectal cancer by 10%. In addition, whole grains contain many antioxidants, such as corn, which is rich in glutathione and vitamin E, and is the "anti-cancer star" of cereals.
3. Choose the right cooking oil and often eat deep-sea fish
Such as flaxseed oil, rapeseed oil, omega-3 fatty acids belong to polyunsaturated fatty acids, are essential fatty acids for the human body, the human body can not automatically synthesize, can only be obtained from food. The degradation products of omega-6 fatty acids can directly lead to inflammation, while omega-3 fatty acids contribute to anti-inflammation, and their daily intake should not be less than 1.3g.
4. Drink tea healthily
Both green tea and black tea have anti-inflammatory activity and contain catechuic acid, brass, polyphenols and other components, which have good preventive effect on a variety of cancers. But it also needs to drink tea according to individual physique to maximize its function.
5. Increase the intake of some spicy condiments
When cooking, you can add a little more cloves, rosemary, turmeric, spring onions, ginger, garlic, star anise, cinnamon and other seasonings. A large number of studies have found that these condiments have anti-inflammatory, anti-allergic effects, and even long-term consumption can prolong life.
The most beneficial weapon to prevent cancer is not to take tonics, but to eat three meals a day. Instead of talking about cancer color change, it is better to prevent cancer scientifically, put cancer through the mouth, jump out of the gourmet trap on the tip of the tongue, establish a healthy diet concept, and make personalized diet choices according to their own situation. Prevent cancer in the future, protect your health!
