"How can the food be bad when it comes out of the fridge?!"
Ms. Zhang, 27 years old this year, works hard alone in Beijing, because it is not easy to make money, she can use the ingredients as soon as they can, even if they have been in the refrigerator for a long time, she is not willing to throw them away.
In addition, because I often have to travel for work, I often come home and eat leftovers that were refrigerated before.
Some time ago, Ms. Zhang felt pain in her upper abdomen, bloating and nauseated, thinking that it was caused by irregular eating, so she didn't care about it after buying some medicine. It was only recently, when nausea and vomiting began, and it was getting worse, that I came to the hospital.
After some examination, a tumor of 2cm ×3cm was found in her stomach, and a biopsy was confirmed to be stomach cancer. After the doctor understood the situation, he sighed and said that it was likely to be related to Ms. Zhang's long-term consumption of food that had been stored in the refrigerator for a long time.

The refrigerator has 3 kinds of food for a long time,
or become an "accomplice" to cancer
We've all made it a habit to put food in the fridge, thinking that this will greatly improve the shelf life of food, but that doesn't mean that food won't "go bad"!
The most common thing in the refrigerator is leafy vegetables. Leafy vegetables contain a certain amount of nitrate, which is easy to produce nitrite if left in the refrigerator for too long, which can be converted into nitrosamines in the body and increase the risk of cancer.
Especially for spinach in leafy vegetables, after 16 hours of stir-frying and refrigeration, the nitrite content in it may also exceed the national standard, so it is recommended to eat the spinach in one go.
Wang Silu, a national senior food inspector, said that green leafy vegetables are generally not recommended to be stored in the refrigerator for a long time, and it is best to eat them within 3 days.
It is also recommended to eat other vegetables within 1 week, and long-term storage will greatly reduce the nutritional value of vegetables, so it is not recommended.
In addition to leafy vegetables, staple foods and nut foods that have been stored in the refrigerator for a long time are also dangerous. These foods have a high chance of mold, and aflatoxin can easily grow when left in the refrigerator for a long time.
Aflatoxin is a super carcinogen, its toxicity is 10 times that of potassium cyanide and 68 times that of arsenic, and it is highly toxic and a strong carcinogen. After entering the body, it will cause the binding of purine residues in the body of DNA, causing DNA damage, which is easy to cause changes in DNA structure and function, and make the body cancerous.

5 strange changes in the body,
It could be a stomach cancer alarm
According to the data in the Guidelines for the Diagnosis and Treatment of Gastric Cancer (2022 Edition), there are 679,000 new cases of gastric cancer in mainland China every year, of which 8 percent of patients are diagnosed in the middle and advanced stages, delaying the best time for treatment.
Ma Xiao, deputy director of the Physical Examination Center of the China-Japan Friendship Hospital, said that the symptoms of early gastric cancer are atypical, and many people will mistake them for benign diseases such as gastritis and gastric ulcers after the symptoms appear, and do not intervene in time, resulting in a delay in the disease.
Zhang Shouru and Zhang Guangqian, physicians of the Gastrointestinal Cancer Center of the Affiliated Cancer Hospital of Chongqing University, reminded that when stomach disease changes to stomach cancer, there may be five signs.
1. Changes in the nature of pain
The pain of benign stomach diseases such as gastritis and gastric ulcer is regular, such as gastric ulcer will appear painful about 1 hour after meals, if this regularity changes, it is necessary to be alert to the possibility of malignant transformation.
2. Weight loss
Gastric cancer will cause patients to greatly reduce their ability to absorb nutrients, lose weight in a short period of time, and have symptoms such as loss of appetite, diarrhea and fatigue.
3. A lump appears in the upper abdomen
If a hard, squeezing lump in the heart socket is a cause for concern, most likely caused by stomach cancer.
4. Heartburn pantothenic acid
Heartburn is usually located below the sternum and feels like a fire, while acid reflux is the feeling of acid in the stomach backing up into the mouth, causing significant discomfort.
5. Black stools
If there is unexplained black stool in the body and it lasts for a long time, it is likely to be caused by the cancerous transformation of the stomach ulcer, and it is necessary to seek medical attention in time.

Stay away from stomach cancer, these 4 things to do well
In January this year, The Lancet Regional Health released a survey on the situation of gastric cancer in mainland China, and the results showed that from 2020 to 2050, the incidence of gastric cancer will continue to decline, thanks to the development of good living habits.
In daily life, do the following 4 things, and stomach cancer will be far away.
1. Eat less pickled foods
The "Public Guidelines for the Risk Management of Gastric Cancer in the Chinese Population (2023 Edition)" points out that excessive intake of high-salt foods will cause damage and atrophy of the gastric mucosa, which in turn increases the possibility of genetic mutations.
2. Don't drink too much
Alcohol can bring adverse irritation to the gastrointestinal tract, which can easily cause nausea, vomiting, diarrhea and other symptoms, which in turn can cause gastric mucosal damage and bleeding.
Studies have found that there is a significant correlation between alcohol intake and the occurrence of gastric cancer, and the risk of gastric cancer will further increase with the increase of alcohol consumption.
3. Avoid Helicobacter pylori infection
Helicobacter pylori infection is closely related to the occurrence of gastric cancer, and the body may not have obvious manifestations after the infection, but behind the scenes, the bacteria will continue to irritate the gastric mucosa in the stomach, resulting in an increased risk of cancer.
Helicobacter pylori is mainly transmitted through fecal-oral and oral-oral transmission, so it is necessary to pay attention to the daily meal system, ensure personal hygiene, and prevent infection as much as possible.
4. Keep your weight under control
Shen Lin, vice president of Peking University Cancer Hospital, said that obese people also have an increased risk of stomach cancer.
Because obese people are at greater risk of gastroesophageal reflux, the proximal part of the stomach is repeatedly irritated by gastric acid, which increases the risk of cancer.
Stomach cancer is a long process, as long as you pay attention to the signals sent by the body and stay away from bad habits, it can be avoided and detected in time.
