Nowadays, many office workers have the habit of bringing meals at noon. Most of them put their food in the refrigerator the night before and take it to work the next day. According to the statement that "the risk of stomach cancer is 3.6 times higher after eating overnight vegetables", the nitrate in overnight vegetables will be reduced to nitrite under the decomposition of bacteria, which is carcinogenic and cannot be removed by heating. The damage and destruction of gastric mucosa may lead to gastric ulcer, atrophic gastritis and even gastric cancer. Let's take a look at the specific introduction.

At present, clinical observation shows that the etiology of gastric cancer is the result of long-term interaction of many factors, which is related to living habits, diet, environmental factors, genetic factors and mental factors, as well as chronic gastritis, gastric polyps, gastric dysplasia, postoperative gastric stump cancer and long-term Helicobacter pylori infection. A single risk factor is not enough to induce cancer.

Eat less overnight meals, but it is not impossible.

If food is stored at 0-4 degrees Celsius for less than 20 hours, it is unlikely to go bad. Eating such a lunch is unlikely to cause stomach trouble. Just like when we travel by plane, radiation is inevitable, but it is not enough to cause disease.

Eat less overnight meals, but it is not absolutely impossible. Researchers from the Food Inspection Institute of the Institute of Product Quality Inspection of Fujian Quality Supervision Bureau tested vegetables, braised pork, braised fish and rice stored in fresh-keeping boxes for half an hour, 4 hours, 9 hours and 24 hours respectively. The results showed that the nitrite content in these diets was less than 65438 0 mg/kg. The nitrite content of meat stored at room temperature for 4 hours is also lower than 1 mg/kg. The national limit of nitrite content is 4 mg/kg for vegetables, 3 mg/kg for fresh meat and 3 mg/kg for rice.

From the health point of view, overnight dishes, especially overnight dishes, are not only low in nutritional value, but also easy to deteriorate. All vegetables contain nitrate, and the content from high to low is: petiole, leaf, stem, root, flower, potato, bulb, fruit and seed. In other words, vegetables such as beans, cucumbers, tomatoes and onions have low nitrate content, while vegetables such as spinach, leeks and celery have relatively high nitrate content and are easy to deteriorate. Bacteria will multiply after contaminated overnight meals, causing gastroenteritis and even food poisoning.

With the accelerated pace of life, many people have some stomach problems, such as common atrophic gastritis. Some patients worry that atrophic gastritis will become cancerous. In fact, only 1% patients may turn into gastric cancer, and autoimmune atrophic gastritis is more likely to develop into gastric cancer. Early gastric cancer is mostly asymptomatic or has only mild symptoms, such as epigastric pain, loss of appetite, bloating, acid reflux and sudden weight loss. When the clinical symptoms are obvious, the lesion is already in the advanced stage. Therefore, if you want to find the disease early, you must insist on regular physical examination. Especially for people over 40 years old, it is one of the effective preventive methods to go to the regular physical examination center every year.

Healthy lunch rule

1. You'd better cook now in the morning. The preservation time of leftovers should be shortened to 5 to 6 hours as far as possible, and they should be thoroughly heated before eating. Leftover rice can easily cause food poisoning, but most of the leftovers look the same, which makes people careless.

2. After cooking, cool naturally, then cover the lunch box and put it in the refrigerator. However, seafood, green leafy vegetables and cold dishes are easy to deteriorate overnight, so it is best not to eat them the next day.

3, open the food, otherwise it is easy to breed bacteria.

4. Promote the use of glassware to reduce chemical reactions.

5. The vegetables to be brought should be fried for six or seven minutes when cooking, so as to prevent further damage to their nutrients when they are heated by microwave the next day.
