"Diligence and frugality" has always been a fine tradition of the Chinese nation. Until now, many people still embody this perfectly; some people will practice "Operation CD" when going out to eat, and most people will store the unfinished meal the night before in the refrigerator and heat it up to eat again the next day.
However, there are recent rumors that rice cannot be reheated and that regular consumption of reheated rice will cause cancer. This statement makes many people panic.
Because rice is one of the indispensable staple foods for every household, most families have the experience of reheating leftover rice for secondary consumption. So, does eating reheated rice really cause cancer?

About rice

The nutrients in rice mainly include: protein, carbohydrates, various minerals (calcium, phosphorus, potassium, sodium, magnesium, iron, zinc, selenium, copper, manganese), vitamins (thiamine, riboflavin, niacin), etc.
Although rice does not contain many nutrients, it has high nutritional value and can be used as a basic supplement to daily staple food. It is also a basic raw material for human nutritional supplements.

[Will eating too much rice make you gain weight?]
Whether a person will gain weight is closely related to the intake of calories; the intake ingredients include carbohydrates, fats, proteins, etc., which can produce a certain amount of heat.
Rice is a carbohydrate. Excessive intake, exceeding the total body intake, will lead to the symptoms of obesity.
However, it does not mean that eating rice regularly will make you fat, because obesity is directly related to your physique, or genetics, and diet.
Although the sugar content in rice is relatively high, eating it regularly will lead to obesity, but you should control the amount of food every time you eat, and exercise properly after meals to avoid obesity.

[Which is easier to gain weight, rice or steamed buns]
Rice has higher calories than steamed buns, but steamed buns have a higher protein content.

Will reheating rice cause cancer?
There are rumors that rice will breed many viruses and bacteria after being reheated. If eaten regularly, it can easily lead to abdominal pain, diarrhea, and even gastrointestinal cancer.
In fact, if rice is kept at room temperature for a long time, it will contain some bacteria, but these bacteria will not cause cancer. At most, they will only cause diarrhea, abdominal pain and other digestive tract problems. If the rice is properly stored, package it in a crisper, refrigerate it, and store it overnight before eating it, it will not bring any danger to health.
However, I would like to remind everyone that it is best not to eat the following foods overnight, and try not to reheat them, otherwise they may easily cause health problems.

Doctor: It is best not to heat these 6 kinds of food twice
. Cold dishes
Nitrite is an essential substance in vegetables, and salt penetration after cold cooking and overnight will produce more nitrite. Nitrite itself has a certain degree of toxicity. If consumed in excess, it may lead to poisoning. In severe cases, it may even cause liver and kidney damage, and there is a risk of cancer!
Therefore, cold vegetables are not suitable for overnight storage. It is best to eat all the cold vegetables at ordinary times, which is not easy to cause waste; relatively speaking, eating them after cooling is also the best for the body.

. Overnight seafood
seafood, such as various shellfish, fish, shrimp, crab, etc., is not recommended to be heated twice.
These foods are high-protein foods, rich in protein, but such foods will be degraded by protein overnight. Protein-degrading enzymes can easily cause serious damage to the liver, which may lead to liver and kidney failure in severe cases.
Moreover, seafood that has been eaten overnight can easily breed a large number of bacteria, which can easily cause serious irritation to the gastrointestinal tract after consumption, causing abdominal pain, diarrhea, vomiting and other problems. Therefore, it is not recommended to reheat seafood twice overnight. It is best to eat it all at once.

. Soy milk
After making fresh soy milk, it is not easy to store, and it is very easy for bacteria to breed.
Generally speaking, soy milk can easily breed a large number of bacteria in three to four hours. Even some sealed packaged soy milk has a shelf life of no more than three days, so soy milk cannot be stored at home.
Therefore, it is best to drink soy milk promptly after cooking. To avoid drinking it overnight, it is best to drink it within 3 hours or so.

. Chicken
Chicken is a kind of meat food that is often eaten in life. Moreover, the fat and calories in chicken are very low, so you don’t have to worry about gaining weight if you eat too much.
Especially during the period of weight loss, many female friends will choose to eat chicken breast, which helps to increase the feeling of satiety and reduce the intake of other high-calorie foods.
During the secondary heating process, uneven heating will lead to inconsistent decomposition of protein in chicken and . Regular consumption will cause certain irritation to the gastrointestinal tract, resulting in abdominal pain, diarrhea, nausea and other problems.

. Shiitake mushrooms
Shiitake mushrooms are of high value and have a smooth taste. When fried with meat, they taste very fragrant. They are also one of the mushroom foods that people often eat in their lives.
Shiitake mushrooms taste good, but for this kind of food, it is recommended not to reheat them, and you can choose to cook them less; because there are bacteria on the reheated mushrooms, they are easily converted into nitrite after heating. Eating them in the body will have a strong impact on the gastrointestinal tract, and may even cause symptoms of abdominal pain and diarrhea.

. Tremella
Tremella has a strong nourishing effect, but after being left overnight, it is more likely to breed bacteria and even cause mildew! It may also breed aflatoxin, which can cause strong irritation to people's liver and stomach.
In nature, plants will produce a certain amount of nitrates when they grow, and Tremella fuciformis contains a large amount of nitrates. It is not recommended to take it overnight when cooking Tremella fuciformis soup or cold Tremella fuciformis, nor is it recommended to overheat.

Which foods that are eaten frequently can cause cancer?
. Alcoholic beverages
Drinking alcohol can cause many cancers in the body. Medical research shows that alcohol can promote cancer transformation, that is to say, it is a catalyst for cancer and can easily destroy the body's immune system function.
As we all know, alcohol is a strong irritant. After drinking, it will cause strong irritation to people's gastric mucosa and affect digestive system ; if a person has stomach problems and drinks too much alcohol, it is easy to develop gastric cancer.
Moreover, clinical medicine has found that people who often drink large amounts of alcohol are not only prone to gastric cancer, but also increase the incidence of oral cancer and esophageal cancer.

. Moldy food
In life, we often find bad potatoes, peanuts and other foods; some people are more economical and often cut off the moldy parts before eating them; however, in fact, the toxins in moldy food have spread to other parts and are invisible to the naked eye. Regular consumption is very harmful to the body.
Spoiled food contains a chemical called aflatoxin, which is even more toxic than the well-known potent poison arsenic! Studies have shown that arsenic is less than 1/68 as toxic as aflatoxin, and even highly toxic potassium cyanide is less than 1/10 as toxic as aflatoxin.
If aflatoxin accumulates in the liver for a long time, it is likely to induce liver cancer . Therefore, spoiled and moldy food must be discarded.

. Processed foods
People are familiar with ham, various red meats and other foods that are processed foods. These foods are rich in protein and lipids . Therefore, long-term consumption can cause rectal cancer.
Moreover, processed foods contain a large amount of nitrite, which can easily induce colorectal cancer. Oncologists also warn people to eat as little processed food as possible.

. Water with excessive arsenic content
Arsenic is a very toxic heavy metal. The chemical formula of arsenic is arsenic trioxide, which shows its toxicity.
If you often drink water with excessive arsenic content, it may cause cancer; of course, the arsenic content of water that meets the national drinking water standards is within a reasonable range and will not affect health.

. Pickled Foods
There is the custom of pickling sauerkraut in many places. Guangdong also has the custom of pickling salted fish. However, nitrosamines and other chemicals contained in pickled foods are harmful to our health.
Some experiments have shown that the main chemicals that cause nasal cancer and pharyngeal cancer are nitrosamines and nitrites. Experts recommend eating more fresh vegetables as much as possible and not eating pickled foods often.
