There are many causes of increased risk of cancer, including the causes that we often unexpectedly and "hide" in everyday life.There are 4 habits when cooking that many people suffer from potential risks can cause cancer cells to produce and develop.
1. Do not turn on the hood, or turn off immediately after cooking
Some people often do not turn on the hood to save electricity.Instead, they only open the window to ventilate or turn off the hood as soon as possible.
However, food will produce oil smoke at high temperatures during cooking.The main ingredient of this oil smoke is Acrolein, which can irritate the mucous membranes of the nose, eyes and throat.If affected for a long time can cause respiratory diseases such as rhinitis, sore throat, tracheitis.
In addition, oil smoke also contains some mutant and cancer -causing substances such as benzopyrene, butadiene, phenol, ... can cause lung cancer when inhaled for a long time.If long-term exposure to oil smoke, the risk of lung cancer will increase 2-3 times compared to normal people.
Therefore, you can turn on the hood before cooking to smoke oil more comprehensive.When cooking, whether for a long time or short, turn on the hood as soon as you turn on the stove.After cooking, wait 3-5 minutes and then turn off the hood.
Long -term breathing of oil can cause lung cancer
2. Do not wash saucepan when cooking the next dish
Some people believe that washing the pot after frying the food is cumbersome, wasting water and unnecessary.Therefore, as long as the food does not smell, usually you will not wash the pot halfway.But in fact, this not only affects the taste of the next dish but also has potential health dangers.
Because most vegetables contain carbon organic substances, this substance will convert to benzopyrene, a strong carcinogen when heated at continuous high temperatures.Typically, the lowest temperature for food to be converted into Benzopyrene is 350-400 degrees Celsius, the bottom of the pot placed on the stove can usually reach over 400 degrees C.
Simply put, if you continue to heat the pot without scrub, grease, food residue in the pot will easily transform into Benzopyrene.What is even more frightening is that the benzopyrene content in dishes in this way is even higher than the direct baked food, especially fish, meat and other protein and fat dishes with high content of high levels.than.
Therefore, you should wash the pans after cooking and when used for the next cooking shortly thereafter.
The food residue in the pot will easily convert into carcinogens when continuing to cook
3. Reuse fried oil
The reuse of cooking oil and inhalation of this oil can increase the risk of cancer, liver, cardiovascular and nervous system.
Heated cooking oil can produce a variety of compounds, including multi -ring aromatic hydrocarbons (PAH), some of these substances have been reported as cancer.In addition, aldehydes will also be produced when reusing cooking oil.This substance can cause physical inflammation to increase the risk of cancer, cardiovascular disease.
Using lots of oil at high temperatures can also interrupt the liver's lipid metabolism, which can lead to alcoholic fatty liver disease (NAFLD) and accelerate liver diseases due to oxidation due to root.Freedom.
Finally, the presence of oxidized fat and advanced glycation ends (Ages) in fried oil is warmed related to chronic diseases, including neurological degeneration.
Because of the "terrible" harmful effects, you should not reuse cooking oil, especially when the oil shows signs of rancid, broken, strange smell and there are many pieces of food.
The reused fried oil can produce many harmful substances for health
4. Eat food overnight
People can still eat old consciousness stored in the refrigerator but it is better to cook just enough to eat all in a meal.
Some foods overnight are at risk of health.For example, green leafy vegetables have high nitrate content, if cooked for a long time or overnight will form toxic nitrite after getting into the stomach, intestines and enter the bloodstream, potentially causing stomach cancer,intestinal cancer, liver cancer and other cancers.
Or fish, meat, seafood and soy products are rich in protein and fat.Under the effects of bacteria, these foods can produce substances that are harmful to the human body and damage the liver and kidney function.
Rice, steamed dumplings and starchy foods that are easy to produce Staphylococcusureus and Aflatoxin, these substances may not be destroyed even when heated at high temperatures and can be harmful to health.
