Rumors: Eating too late will increase the risk of stomach cancer. Eating supper is very harmful to the stomach, because the lifespan of gastric mucosal epithelial cells is very short. It takes about 2 to 3 days to regenerate. The regeneration process is usually performed during the nighttime gastrointestinal tract rest. Frequent meals at night can cause gastric mucosa to be repaired in time and even damage the gastric mucosa.
Truth: Eating too late at night is often considered to be "stomach injury", "to make the stomach not rest", and even considered to be the culprit in the occurrence of gastric cancer. In news reports, the headline “Young white-collar workers work overtime to eat at night and suffer from stomach cancer†appears from time to time. However, even in some cases, "eat supper" and "stomach cancer" really occur one after another, this does not mean that there is a connection between them.
Should gastric mucosa be repaired at night?
The rumors mentioned that the night is the time when the gastric mucosal cells rest and recover, and this time can't stimulate the peristalsis, let it sleep well. If you eat at this time, they will cause serious damage and may even cause cancer. Is this argument justified?
Eating supper causes stomach cancer? There is no evidence to support
Like the mucous membranes or skin of other parts of the body, the usual repair of the gastric mucosa depends on the constant replacement of epithelial cells. Gastrointestinal mucosa is one of the most rapidly growing tissues in the body. It maintains a balance between hyperplasia and growth and the loss of cells caused by exfoliation on the surface. Newborn cells migrate from the proliferative zone to the surface and gradually differentiate into epithelial mucosal cells. At the same time, the senescent epithelial cells flake off the surface and are devoured by the surrounding epithelial cells. The gastric mucosa will be completely renewed in about 3 to 5 days. The process of replacement and replacement of mucosal cells is ongoing, and no studies have found correlations with circadian rhythms. Therefore, it is unfounded that the rumors mentioned that the gastric mucosa must be repaired when it is rested at night, and that eating at night will hinder the repair.
Do you have stomach cancer? There is no evidence to support
The theoretical explanation mentioned in the rumors is not reasonable. Then is there any research data suggesting that the risk of eating supper is related to the risk of stomach cancer? The answer is no. A search in Pubmed et al.'s medical database reveals that no studies have linked late eating (and the short interval between eating and sleeping) to gastric cancer risk.
When referring to the risk factors of gastric cancer, neither the United Kingdom Cancer Institute nor the American Cancer Society, the UpToDate-based evidence-based medical institution, nor the guidelines for diagnosis and treatment all included eating time. Although various professional organizations believe that diet is an important factor affecting the incidence of gastric cancer, what they emphasize is “what to eat†rather than “when to eatâ€: excessive salt and pickled food intake is the real risk associated with gastric cancer. factor.
Eat too late, esophagus may be injured
There is no evidence that eating night food is related to the onset of gastric cancer, but if you eat too late and go to bed after eating, it may also cause some trouble to the digestive system.
Some studies have shown that short intervals between eating and sleeping increase the risk of gastroesophageal reflux. The reflux of gastric acid will not only cause a "heartburn" discomfort but also damage the esophagus. If the esophageal mucosa is stimulated by gastric acid for a long time, it may produce so-called "atypical hyperplasia" and gradually develop into precancerous lesions, thereby increasing the risk of suffering from esophageal cancer.
Studies have shown that a short period between eating and sleeping is indeed a potential risk factor for esophageal cancer. A paper published in the "Journal of Oncology Yearbook" in August 2014 also pointed out that this factor is also related to gastric cardia cancer occurring at the junction of the stomach and esophagus. The good news, however, is that these studies also found that you can reduce this risk by avoiding sleep at night and taking a walk after a meal.
How to eat stomach cancer?
What are the factors associated with gastric cancer? We might as well take a look at the professional answer. Vincen T. DeVilta of Yale University Comprehensive Cancer Center and his colleagues listed a series of evidence-supported high-risk factors for gastric cancer in the 9th edition of Cancer - Principles and Practices of Cancer Therapy, edited in 2011. . In addition to genetics, several important factors affecting the incidence of gastric cancer include diet, occupation, smoking, Helicobacter pylori infection, obesity, and radiation exposure. In terms of diet, high salt intake, excessive intake of preserved foods, and insufficient intake of vitamins A and C are all associated with increased risk of gastric cancer.
It can be seen from here that in order to reduce the risk of gastric cancer, “eating†is indeed an area that needs attention. However, compared to eating time, "what to eat" deserves more attention. A series of previous studies have found that high salt intake, high salted food intake is related to the incidence of gastric cancer, and the lack of vitamin C and other nutrients will also have adverse effects. Many people will choose salted meats, sausages, or barbecues as a nightingale. If you say that eating supper really increases the risk of gastric cancer, these “heavy-tasting†recipes may have to bear the main responsibility.
In addition, another notable factor is H. pylori. At present, it is believed that Helicobacter pylori infection will lead to the occurrence of gastric ulcer. In the course of repeated damage and repair of gastric mucosa, gastric epithelial cells may suddenly appear "mutation" and transform into precancerous lesions, thus increasing the development of The possibility of cancer. For patients with Helicobacter pylori infection with ulcers, a standard H. pylori eradication therapy is required. In order to prevent Helicobacter pylori infection, it is important to pay attention to food hygiene. The risk of H. pylori infection may also increase if you choose a food stall that is not hygienic.
In addition, staying away from tobacco, eating more fruits and vegetables, and maintaining a healthy weight also help prevent stomach cancer.
in conclusion:
There is no evidence to support the argument that eating supper causes stomach cancer. However, sleeping soon after eating may cause gastroesophageal reflux and damage the esophagus. Instead of pushing your responsibilities to the nightingale, it's better to manage your diet and lifestyle to protect your stomach.
