Explaining the cause of eating leftovers in the refrigerator can cause cancer

Even if stored in a refrigerator, there is a process of protein conversion that occurs, causing food to lose nutrients and turn into toxins.

The cause of leftovers left in the refrigerator can cause cancer

Information posted on the social network about a Malaysian woman who had cancer just because she ate leftovers in the refrigerator from the previous day made many people feel confused.

According to family members, during the past 10 years, this woman has a habit of eating leftovers to stay overnight in the refrigerator. After a long time, she was found to have stomach cancer. After only 1 year, her body rapidly decreased from 60kg to 28kg and the progress of the disease was so fast that it was unthinkable. Last July, she was diagnosed with stomach cancer. After going through 8 cycles of chemotherapy and surgery to remove the stomach, the disease is uncontrolled and leads to death.

Malaysian woman is believed to have cancer because in 10 years of eating leftovers in the refrigerator.

Before this information, many people wondered if it was really dangerous to eat leftover food in the refrigerator until the next day, leading to cancer?

Many people have the idea that if leftovers can be stored in the refrigerator for tomorrow, it will be fine the other day.

But according to food chemical engineer, Ho Thi Thu Thuy, a former Central Food Testing Center official: "Although it is difficult to conclude that overnight food is a cause of cancer, it is undeniable. One thing is that the food stored in the refrigerator is altered, but the speed is slower than the outside, because at refrigerator temperatures are usually 5-8 degrees Celsius, cold-loving microorganisms are still growing and too The protein conversion process in food still takes place, this process produces nitrates, nitrites, and nitrate when entering the human body to participate in reducing reactions in the stomach and intestines due to the effect of digestive enzymes producing NO _2. - Very toxic nitrite, with a concentration of 0.01 mg / l, can be toxic to human health ".

When nitrite poisoning , the body will not be able to fulfill respiratory function, manifestations such as dyspnea, suffocation. Higher levels can inhibit oxygen, leading to a lack of oxygen in the blood, which can make the body dizzy and faint while working or playing. Severe poisoning if not treated promptly leads to a high risk of death.

In addition, NO ₂ - in the body is easy to work with amines forming nitrosamine-1 precursor compounds. High content of nitrosamin makes the body unable to eliminate it, accumulating long time in the liver can cause poisoning and cancer.

Many consumers often think that storing food in the refrigerator is safe, however, it is not true.Even if stored in a refrigerator, there is a protein conversion process, which causes food to lose nutrients.

Besides, cooking at high temperatures also helps kill harmful bacteria and molds in food, but the concentration of toxins such as nitrite remains unchanged.

Unscientific eating habits kill us

Zhejiang University (China) has done some experiments to prove that uneaten food, although stored in the refrigerator, is still susceptible to decomposition, producing nitrite compounds - one of the causes of cancer.

Nitrate (chemical formula NO ₃ -) and nitrite (chemical formula NO ₂ -) is a compound of nitrogen and oxygen, exists in food as a result of the decomposition of organic compounds with natural origin. Normally nitrates do not cause health effects, but if the nitrate concentration is too large or nitrate is converted into nitrite, it is toxic to humans. Mild intoxication manifested by poisoning, long-term toxicity can be the cause of cancer.

In order to measure the nitrite concentration in cooked food overnight, the team selected 4 plates of food: stir-fried vegetables, stir-fried chives with eggs, meat stock and warehouse herring. These dishes are prepared by a well-known restaurant, which is both hygienic and nitrite-compliant. Four plates of food are sealed and stored in a refrigerator at 4 degrees Celsius.

After 6 hours, the nitrite content in fried vegetables increased by 16%, fried chives in eggs increased by 6%, particularly the nitrite content in the meat stock and the fish stock increased to over 70%, exceeding the standard threshold of 3mg / kg of meat.

After 18 hours, the dishes were microwaveed and then heated to test, the nitrite content in sautéed vegetables increased dramatically, 443% higher than the measured amount after 6 hours. The content of nitrite in barramundi also increased by 54%, fried chives in eggs increased by 47%, particularly in the stock of meat stock, there was no big change in nitrite content.

According to health experts, there are many cases of cancer that are caused by bad eating habits, including the habit of regularly eating leftover food for many days. In addition, many young people have other bad habits such as eating too many fried foods, spicy marinated baked goods in unsanitary roadside shops. These habits make nitrite build up more in the body and the risk of cancer is also higher.

Besides, you need to know how to preserve some common foods, or use them daily appropriately to ensure safety for your health.
