"Don't throw away the leftover food. You can still eat it hot for the next meal. Throwing it away is a waste of food."

I think of what many young people in life have heard from the elderly at home. This sentence, don’t throw away the leftovers, I believe has aroused the screams of many people.

Obviously it has been heated many times, the taste has deteriorated, and it may have gone bad, but the old man at home is still reluctant to throw the leftovers into the trash can. Those who have a refrigerator at home will keep it. Store in the refrigerator, frozen or fresh.

Diligence and frugality are the traditional virtues of the Chinese nation. This way of life is preserved and passed down from generation to generation through their own personal experience.

A few decades ago, people were still in a poor era when they did not have enough to eat or wear warm clothes. At that time, being able to eat steamed buns and sweet potatoes at home and not going hungry was a luxury for most people. At that time, there was a lot of waste. for crime.

With the concerted efforts of the Chinese people, heavy industry has risen, light industry has developed rapidly, and every household is striving to be well-off, and has long since got rid of the embarrassing life of eating glutinous rice.

The premise is to ensure good health.

After the awareness of health care has increased, people store some food in the refrigerator on the basis of wasting as little food as possible, and wait until the next meal to heat it up and continue eating. Some people: rice It is best to eat the food at once and throw away the leftovers as soon as possible, because reheating can cause cancer.

It aroused people's doubts. Some people objected to this statement: When I was poor, there was always leftover rice at home, and it was not thrown away directly at that time. I suffered from cancer decades ago. The number of people is much smaller than today.

Of course, some people agree: the physical fitness of modern people and the older generation is much worse, physical labor has been reduced, and they eat a lot of unhealthy junk food. In order to Be healthy. It is not recommended to eat some foods after reheating them.

So, is there any scientific basis for the statement that "rice can cause cancer after being reheated"?

01

Reheating rice can cause cancer. Is it true or false?

This is mainly because bacteria and microorganisms will be produced during the storage process of rice. After secondary heating, nitrite will be released and converted into nitrosamines through gastrointestinal absorption and digestion, bringing carcinogens.

However, as long as it is stored properly and the storage time is shortened, a large number of bacteria and viruses will generally not grow. As long as it is completely heated on the second day of use, it will not bring substantial danger to the human body, let alone It can cause cancer. However, for everyone’s safety and health, it is best to eat fresh rice.

There are obvious differences in the nitrites and microorganisms produced during the storage of different types of vegetables. In fact, the leftovers themselves are not that scary, but it does not mean that they are absolutely safe. When eating leftovers, you should Ensure the safety of food before eating to avoid potential safety hazards to the body.

Doctors remind: Try not to reheat these 6 items

1. Half-boiled eggs

The largest of eggs The danger is that salmonella will be hidden, but this bacteria can be killed by high temperatures, so this bacteria does not appear in normal fully cooked eggs.

Many people become infected with salmonella from eating half-boiled eggs. Half-boiled eggs themselves contain the risk of causing disease. After being left for a long time, the germs inside will multiply and grow on their own. The harm of such food to the human body can be imagined.

2. Seafood

After long-term storage of seafood, bacteria and microorganisms will be produced. Secondary heating cannot completely eliminate bacteria and viruses, which will not only affect the taste, but also The seafood loses its original nutritional value.

Long-term consumption of reheated seafood will have adverse effects on gastrointestinal health, especially for people with gastroenteritis and weak spleen and stomach function, which can easily aggravate the development of the disease and cause diarrhea, flatulence, and pain.

3. Celery

Celery is rich in dietary fiber, which not only facilitates the digestive motility of the gastrointestinal tract, but also reduces the burden on the gastrointestinal tract.

However, celery cannot be reheated. Celery will also produce a large amount of nitrite after cooling. After heating, the nitrite will be released, which will increase the harm to the body.

4. Tremella

Tremella is known as "affordable bird's nest". If the prepared Tremella is stored for a long time, a small amount of bacteria and microorganisms will be produced. Furthermore, Tremella soup will It gradually cools over time, so it needs to be reheated before consumption.

Repeated heating will cause the nutrients in the white fungus soup to continue to lose, and it will also affect the taste. After long-term storage, harmful ingredients will be produced in the white fungus soup. Therefore, it is not recommended that you consume it twice for a long time. Heated Tremella fuciformis is best eaten in one go.

5. Mushrooms

After high-temperature cooking, mushrooms will produce a large amount of nitrates. These nitrates will be stored in the refrigerator at low temperatures. If they are heated and continued to be eaten the next day, people will The level of nitrite in the body will double.

If you often eat mushrooms that have been heated for a second time, you are prone to symptoms such as abdominal pain and diarrhea. In severe cases, you may develop gastric cancer and colorectal cancer.

Therefore, it is recommended not to continue to eat mushrooms after reheating them for the second time, try to eat them all at once, and throw them away if you can't finish them.

6. Milk

Milk is generally not boiled. The protein still exists during the heating process, but it is difficult for the human body to absorb it. Heating again, in order to completely sterilize, it is best to boil. At this time, a large amount of vitamin B will be lost.

In addition, children's milk powder is brewed with warm boiled water and heated again. The high temperature causes most nutrients to be lost, leaving only food "residues".

03

"Reheating food" is not terrible, but please treat leftovers scientifically

"Storage scientifically"

< p> Reduce the number of times you use chopsticks and other tableware to flip leftovers, and use safe and clean food lunch boxes to ensure sealing and material safety.

Different layers of the refrigerator have different temperatures. Try to put leftovers in the low-temperature area of ??the refrigerator to delay the proliferation of bacteria and other microorganisms.

Leftovers need to be "heated through"

Leftovers will be safer after being "heated through". It can not only restore the taste and texture of the food, but also avoid many food safety issues.

"Repeated heating" is not recommended

Although the safety risk of thoroughly heated leftovers is very small, repeated heating has many "disadvantages", such as nutrient loss, reduced taste, nitrite Salt issues, etc.

Therefore, don’t leave any leftovers if you can. If there are any leftovers, it is best to heat them up and eat them all at once. If there are a lot left over, please “eat as much as you can and heat them up” and continue with the rest. Place in the refrigerator to chill.

Extended reading - Microwave ovens emit radiation, will heated food have radiation residues?

There are rumors that microwave ovens radiate a lot of radiation, and food heated with them will have radiation residues.

In fact, microwave ovens do contain radiation, but these radiations are "non-ionizing radiation" and will not directly cause harm to the human body during normal use. Food heated in a microwave oven is not radioactive.

It should be noted that when purchasing a microwave oven, you should choose products produced by regular manufacturers and bearing the 3C mark. If the microwave oven is damaged, it should be replaced in time. #爱乐Health Guide#
