When it comes to the most important digestive organs in the human body, I think everyone will immediately think of a word: stomach!
Yes, all food and water that enter the human body through the mouth will begin to digest as the esophagus first enters the stomach.
The stomach is the initial digestive organ and the most important link in the digestive system. However, the stomach itself is very fragile, and the long-standing bad eating habits in daily life will cause damage to the gastric mucosa and promote the emergence of various chronic stomach diseases.
Affected by the changes in China's life, eating habits and other aspects in recent years, the incidence of chronic stomach disease in China is also gradually increasing, and there is a trend of gradual rejuvenation, so there is also a "ten people and nine stomachs" in life.
Not only that, in recent years, the incidence of stomach cancer in China has also continued to grow, and the number of newly diagnosed stomach cancer patients in China will reach nearly 480,000 in 2020.
Behind the occurrence of stomach cancer, in addition to being related to objective factors such as genetic genes and age, acquired factors are precisely the most important behind-the-scenes drivers. In particular, maintaining unhealthy eating habits for a long time will increase the possibility of stomach cancer in the future.
For example, the following bad eating habits may be too late to correct now:
1, eat too salty
For people who are keen on health, it should be known that high-salt foods are one of the risk factors for high blood pressure.
As everyone knows, the damage it causes is not just high blood pressure. Salt has a high degree of permeability, in the process of contact with the gastric mucosa, it will directly destroy the protective layer of the gastric mucosa, causing corrosion and damage to the gastric mucosa, promoting gastric ulcers, gastritis, erosion and other problems.
Not only that, some pickled vegetables and processed meats not only contain extremely high salt, but also have a large amount of nitrite, which can be converted into a class of carcinogen nitrosamines in a specific environment after entering the body. Under the dual harm of carcinogens and chronic stomach diseases, it may develop into cancerous changes in the future;
2. Long-term alcoholism
Among the types of carcinogens published by the International Agency for Research on Cancer, alcohol is included in the list of class 1 carcinogens, which is an independent risk factor for gastrointestinal cancer and liver cancer. Alcohol damage to the stomach can be divided into two parts, the first is the direct damage caused by alcohol contact with the gastric mucosa, long-term alcoholism can induce chronic gastritis, gastric ulcers and other digestive tract diseases, gastrointestinal diseases repeated attacks, cells continue to repair and damage, may promote DNA mutation.
Second, ethanol and its metabolite acetaldehyde, have cytotoxic effects, which can alter the expression of DNA genes in cells, causing healthy cells to become cancerous. The longer you drink alcohol and drink high-concentration liquor, the greater the likelihood of stomach cancer in the future;
3, eat too hot
The International Agency for Research on Cancer has included food that exceeds 65°C in Class 2a carcinogens, which means that it may be carcinogenic to the human body, especially closely related to gastrointestinal cancer. This is the case because the temperature that the mucous membranes of the digestive tract can accept is very limited, only around 40 to 50 ° C.
Food above 65 ° C will cause mild mucosal burns. If you eat hot food in large quantities for a long time, it will lead to the gradual development of inflammation, erosion and ulceration, atrophic gastritis, intestinal metaplasia and atypical growth of the gastric mucosa, and eventually cancerous.
Of course, it needs to be emphasized here that not only exposure to such foods will definitely cause cancer. The relationship between any carcinogen and cancer is only possible, and they are based on long-term, large-scale exposure.
Therefore, there is no need for you to panic excessively, what you have to do now is to improve bad eating habits and conduct relevant targeted screenings on a regular basis.
