Is there any relationship between overnight rice and stomach cancer

The rumor on the internet that "bringing lunch to lunch has become a cause of stomach cancer in young women" has attracted widespread attention! So, can overnight meals cause stomach cancer? Let me introduce it to you below.

Will overnight meals cause stomach cancer?

Studies have shown that the risk of stomach cancer from overnight meals is 3.6 times higher, because overnight meals will slowly undergo an oxidation-reduction reaction with the air after being left out for a long time, and the nitrates in the food will be reduced to carcinogenic nitrites, a chemical component that cannot be removed no matter how it is heated. Therefore, over time, it is easy to damage or destroy the gastric mucosa, which may further lead to atrophic gastritis, gastric ulcers, and even gastric cancer.

We should try to eat less overnight meals, but that doesn't mean we can't eat them at all. Researchers have tested braised fish, rice, green vegetables and braised pork in fresh-keeping boxes after they were taken out of the pot and refrigerated for half an hour, four hours, nine hours and twenty-four hours respectively. The results showed that the nitrite content in these meals was all less than one milligram per kilogram. The nitrite content of meat stored at room temperature for four hours was also less than one milligram per kilogram. The national safety standard for nitrite content is: four milligrams per kilogram for vegetables, three milligrams per kilogram for fresh meat, and three milligrams per kilogram for rice. From this perspective, occasionally eating some overnight meals will not have much impact on health.

However, from a health perspective, overnight dishes (especially overnight greens) are not only less nutritious than freshly cooked dishes, but also easy to spoil. Fruits and vegetables, from petioles and leaves to rhizomes, fruits and seeds, all contain nitrates. So don't take it lightly. In addition, if overnight meals are not well preserved, they are easily contaminated, which in turn leads to a large number of bacterial reproduction, thus inducing gastroenteritis and even food poisoning. Therefore, how office workers eat is really a dilemma. Can overnight meals be eaten? Yes. Does overnight meals cause stomach cancer? Yes. But eating a little bit will not have much impact. So how to grasp this "degree" is a matter of opinion.
