Will reheating of rice cause 'cancer'? Doctor's advice: these 5 kinds of food, it is best not to reheat

Frugality is the traditional virtue of our Chinese nation. Usually, when many families have leftovers, they will leave the next meal to eat, especially in the evening, they may be left to eat the next morning, which also saves making breakfast.

Leftovers are carcinogenic. Is this true? Especially the staple food - rice, many families have a large population, and it is easy to have leftovers when the staple food is too much, so many people choose to make egg fried rice the next day?

Does reheating rice cause cancer?

According to clinical medical statistics, there are as many as 936,300 patients with organ epithelial tissue necrosis in China, and oral cancer accounts for 26.8% of the total. The incentives are closely related to dietary and environmental factors.

Adults and middle-aged and elderly people have different dietary concepts, especially in the secondary use of food, which leads to a certain psychological separation, just like the following difference between Aunt Liu and her son:

-Mom, what about the leftover rice from last night? I didn't tell you that the second heating can produce harmful substances that cause cancer disease.

• Oh, I've had it for so many years, isn't it okay? Don't just listen to rumors online.

The domestic functional food team and disease data team have confirmed this through multiple studies:

The correlation between cancer and human direct dietary factors was 25.9%. Refrigerate the rice for 5-6 hours before reheating to serve. The bacterial components grown on the surface will effectively disappear, and it will not cause certain irritation after ingesting it again.

In view of the formation of this statement, it is recommended that everyone be sober scientifically and treat rumors with a correct and reasonable viewpoint is the best choice.

However, rice that cannot be eaten at night should pay attention to the choice of environment and temperature during storage. After cooling completely, put it in the upper part of the refrigerator and cover it with plastic wrap to avoid odor and cloudy reaction with other meat products.

During the second heating, the temperature and time should also be controlled to avoid uneven heating, resulting in persistent abdominal pain, diarrhea, nausea, vomiting and other food poisoning reactions.

Doctor's advice: these five kinds of food, it is best not to reheat.

• Tremella

Tremella is a dish that we often eat. In the market, we often buy dried Tremella, which can be made into soup. It is very delicious. Tremella is rich in nutrients and has a good effect on our body.

However, if the white fungus soup is not eaten at one time, it is not recommended to eat the second meal after heating, because the white fungus will produce a certain amount of nitrate during the natural growth process.

Tremella has relatively high nitrate content. If it is left for a long time, a certain amount of nitrate will be converted into nitrite, and it will be converted into nitrosamine after entering the human body. It is a carcinogen that does great harm to the body.

--celery

Celery is rich in dietary fiber, which can promote gastrointestinal motility, prevent and relieve constipation, and has many benefits to the human body. Celery can also play a certain role in lowering blood pressure.

However, if celery is stored for a long time, the nitrite in celery will also increase and enter the human body to form harmful substances. Therefore, celery is not suitable for secondary heating and must be paid attention to.

--seafood

Many marine products are rich in vitamins and minerals, which can supplement the nutrients needed by the human body, provide the energy needed by the human body, and have a good tonic effect.

Although the nutritional value of seafood is relatively high, it is not recommended to heat seafood, because seafood is stored for a long time, and a large amount of degradable protein will be produced.

• candy heart egg

There are many ways to make eggs. The nutrition of hard-boiled eggs is the highest value for preserving eggs, but some people like to cook some candied eggs while they are cooking, half-boiled.

Eggs contain salmonella, which can be completely killed at high temperatures. However, if you eat half-boiled eggs, you may be at risk of contracting salmonella, a disease.

If it is left for a long time, the bacteria will multiply by itself, and the protein structure in the egg will undergo serious changes after repeated heating, causing the bacteria to enter our stomach and affect our health.

--milk

Milk can supplement the calcium needed by the human body, provide the nutrients needed by the human body, and keep people in a good mental state. Milk is common among older adults and teens.

But avoid reheating the milk, as a lot of it is pasteurized, so keep it sterile when stored.

If it is heated twice, it will reduce the activity of the protein and make the milk lose its nutritional value. If stored for a long time, microorganisms may grow and cause physical discomfort.

How to prevent leftovers from spoiling?

1. Leftovers are best kept in glass containers.

Overnight food is not the same as a flood of beasts, as long as it is not left for too long. If you eat too often, you don't need to change the color. Nitrates and nitrites do little harm to the human body.

2. Cover with plastic wrap and cool in the refrigerator.

Cooling is because the hot food suddenly enters a low temperature environment. The heat of the food will cause water vapor to condense, promote the growth of mold, and cause the food in the refrigerator to become moldy. After cooling, put it in the refrigerator in time, even in winter, do not leave it outside for a long time, because the refrigerator has Certain antibacterial effect.

3. Separate storage.

Different leftovers must be stored separately to avoid cross-contamination of bacteria. It also needs to be stored tightly in a clean container, such as a plastic box, plastic bag, or a plastic film attached to the plate.

4. The storage time of leftovers should not be too long.

Best eaten within 5-6 hours. In general, heating at high temperatures for a few minutes kills most pathogenic bacteria, but if food is stored for too long, nitrite and aflatoxins are produced, heating will not work.
