The consequences of repeated frying of cooking oilRepeatedly frying cooking oil will have many negative consequences:
1. ** Production of harmful substances **
- It will form substances that may cause cancer such as acrylamid, polyaromatic aromatic compounds, and heteroaromatic compounds. After being cooked at high temperatures and repeatedly used, the content of harmful compounds in the oil would increase significantly.
- It produced a large amount of trans-fatty acid, which entered the human body and led to chronic diseases such as obese, heart disease, diabetes, and dementia.
- The reaction produced a lot of volatile substances, including saturated and un-saturated aromatic compounds, and polyaromatic compounds. Among them, acrolene was the most dangerous inducing agent in oil smoke that could cause lung cancer.
- When the water is released, the fried food will release water at high temperature, which will cause the edible oil to be digested and produce fatty acid, which will cause the edible oil to quickly become rancid and deteriorate.
- Isomerization reaction occurred, and the cis-fatty acid in the edible oil was converted into trans-fatty acid.
- After repeated use of the oil for seven times, the content of toxic substances (malondiadehyde) could be increased by more than 30 times. Malondiadehyde could cause the growth of the body to stagnate, the liver to swell, the liver function to be damaged, and even the risk of cancer.
2. ** Harm to health **
- Liver damage, because edible oil contains more cancer-causing ingredients, such as aflatoxin.
- It was easy to suffer from cancer of the digestive tract. In addition to aflatoxins, it also contained a component of pyrene, which had a strong cancerogenic effect.
- If you consume too much cooking oil that is rich in cancer-causing substances for a long time, the risk of lung cancer will increase.
- After all kinds of cancer-causing substances and chemicals in edible oil enter the human body, they will cause the defense barriers of various organs and systems in the human body to decline and even destroy these defense barriers.

Can genetically modified cooking oil be used in kindergarten?At present, there was no clear law prohibiting the use of genetically modified cooking oil in kindergarten. However, judging from the past situation, there were some controversial phenomena. For example, in 2011, thousands of teachers and students of Beijing Forest University jointly signed a real-name system to request the school leaders to take measures to ban the use of "chemical extraction" genetically modified "edible oil" in the canteen. The Ministry of Agriculture's kindergarten "uses non-genetically modified oil" for edible oil, and some kindergarten systems prohibit the entry of genetically modified edible oil. These situations showed that although there were no mandatory laws, some kindergarten tended not to use genetically modified cooking oil for health and safety reasons.

What harm will happen when cooking oil is used repeatedly?There were many dangers in the repeated use of cooking oil:
1. ** Health risks **
- ** Increases the risk of chronic diseases **: repeated use will change the chemical properties of the oil and produce peroxided fat, which may lead to chronic diseases such as heart disease and high blood pressure.
- ** Affects human metabolism **: Fatty fat contains substances such as steroid, calcium, and iron that affect metabolism. Reuse of old fat will cause these substances to enter the body and cause negative effects.
- ** Lead to an unbalanced diet **: Oil contains different fatty acid, and repeated use of oil will increase the intake of unhealthy fatty acid, which will increase the risk of cardiovascular diseases.
- ** Affects vision **: In the oil that is heated for many times, nutrients such as vitamins A and E are destroyed, which will increase the risk of eye diseases in the long run.
2. ** In terms of digestive problems **: Eating old oil will produce a large number of harmful substances, such as acids, fatty acid, copper, etc., excessive intake will cause discomfort in the digestive tract, and even lead to stomach diseases such as inflammation and inflammation.
3. ** Carcinogenic risk **: Oil that is repeatedly used at high temperatures will produce cancer-causing substances such as methylethylpyrene and acryl amine. These cancer-causing substances accumulate in the human body and increase the risk of cancer.
4. ** Nutrient content of food **: The nutritional value of repeatedly used edible oil is greatly reduced, such as increased calories and imbalance of fatty acid ratio, which affects the nutritional content of food.
