As a traditional virtue of the Chinese nation, thrift and thrift, whether in the era of lack of economic materials or the advanced era of today's diversified diet, have always run through the people's subtle thinking.
According to the big data statistical survey of food science, more than 98.5% of households usually choose to put them in the refrigerator for meals and staple foods that cannot be eaten at night, and the secondary heating method is eaten again.
Affected by today's health science and health concepts, a small number of people believe that eating leftovers and leftovers will lead to cancer induction, in view of the formation of this statement, is there a certain scientific cognition correct view? #夏方养生指南 #
01
Can secondary heating of rice cause cancer?
According to clinical medical statistics, the number of people suffering from organ epithelial tissue necrosis and cancer-induced diseases in mainland China is as high as 936,300, and oral cancer accounts for 26.8% of the total, and the triggers are closely related to dietary factors and environmental factors.
The dietary concepts held by the adult population and the middle-aged and elderly groups are not the same, especially in the secondary use of food, resulting in a certain degree of separation, just as the following divergent views exist between Aunt Liu and her son:
- Mom, why did you eat the rice left over from last night? I didn't tell you that the secondary heating of rice will produce harmful substances, which can lead to the induction of cancer diseases.
- Oops, I've eaten for so many years, isn't it all right? Don't just listen to the rumors on the Internet.
In view of whether the secondary heating of rice will cause cancer, whether there is a certain scientific principle, the continental functional food team and the disease data team have confirmed through a number of studies:
The association between the induction of cancer diseases and the existence of direct dietary factors in the human body is 25.9%, and when rice is stored cold for 5 to 6 hours, when it is eaten by secondary heating, the bacterial components bred on the surface will effectively disappear, and it will not bring certain irritating effects after re-intake of the human body.
In view of the formation of this kind of statement, it is recommended that everyone must be scientifically clear, and the use of correct and reasonable views to treat rumors is the best choice.
However, in the storage process of rice that cannot be eaten at night, we should also pay attention to the choice of environment and temperature, and after it is completely cold, it is placed in the upper environment of the refrigerator, covered with plastic wrap, and avoids odor turbidity reaction with other meat products.
When performing secondary heating, it is also necessary to control the temperature and time to avoid uneven heating, resulting in persistent abdominal pain, diarrhea, nausea, vomiting and other food poisoning reactions.

Doctor's advice: These 5 kinds of food, it is best not to reheat
1. Mushrooms
The average price of mushrooms sold on the market is controlled to about 3.5 to 4.5 yuan a catty, because of its price, the taste is loved by most families, usually choose mushrooms with meat products to cook together, to meet their own appetite.
For the mushrooms that cannot be eaten, it is recommended that you throw them away in time, so as not to cause gastrointestinal discomfort symptoms through secondary heating, although it is through low temperature refrigeration, it is difficult to avoid the breeding phenomenon of cold mushroom ingredients.
The fungal components bred by the surface layer are converted into nitrate components through the heating process of 65 to 75 °C, and while the balance of sodium and salt is disturbed after ingestion, it also leads to indirect abdominal pain, diarrhea, nausea, vomiting and other poisoning reactions.
2. Spinach
The vitamin C, vitamin K and vitamin B12 components contained in spinach can help supplement the micronutrients lacking in the body after ingestion, promote the peristalsis of their gastrointestinal tract, and also help improve the symptoms of constipation.
However, for spinach that cannot be eaten, it is not recommended that everyone carry out secondary heating, so as not to cause a sharp increase in nitrite components, aggravate the pressure burden on the gastrointestinal tract, and lead to food poisoning.
For leafy greens such as spinach and greens that cannot be eaten, it is necessary to avoid frequent cooking and stir-frying, and make appropriate choices according to natural needs and family needs.
3. Seafood
The common types of seafood sold on the market are fresh shrimp, abalone, crab, flower clams, oysters, etc., which contain high-quality proteins, oil components, and caloric substances to help improve the self-functioning state of the overall sexual organs and replenish the energy lacked by the body.
However, it is not recommended that we carry out secondary heating of seafood foods, the best time for storage should be controlled for about 3 to 4 hours, and there are also options that pay attention to temperature and environment, so as not to make direct contact with the outside air, resulting in overnight corruption, and after re-intake of the human body, it is easy to have diarrheal pain discomfort.
4. Loose eggs
According to the factors of increasing the economic demand of today's population, the eggs sold on the market are also divided into various types, which are affected by the temptation of sterile advertising slogans, so that most families have a large demand for loose eggs.
You can eat bibimbap raw, properly heat the diet method to leave the yellow heart to achieve a sense of taste, for the loose eggs that cannot be eaten, it is not recommended that you carry out secondary heating, so as not to lead to the loss of nutrients and the breeding of bacterial ingredients.
5. Milk
The iron, zinc and calcium contained in milk help to replenish the energy substances lacking in the body, promote growth and development, and also benefit their own bone health.
For these drinks of milk, after unpacking, you must drink in time, you can also store it for 7 to 12 days by placing the refrigerator cold storage method, avoid direct contact between milk and external air for 5 to 6 hours, so as to avoid volatile reactions.
Although it is through the method of secondary heating, it has not been able to fundamentally achieve the bacterial substance removal reaction, and it is easy to cause diarrhea, abdominal pain and other reactions after drinking again.
