I did this while cooking and my whole family got sick

In our daily lives, we may have some small habits of cooking. Many people think that this is a kind of economical behavior, or it seems to be a correct behavior, but these bad habits may cause you to get sick!

1. Cooking without washing the pan: Benzopyrene is produced, which can easily lead to diseases

Many friends have this habit: after frying eggs, there is still some oil in the pan, so they add some oil and then continue to fry other dishes. This is very economical. However, the seemingly clean surface of the pot may be attached with grease and food residues, which may produce benzopyrene when heated again at high temperature. Moreover, if you do not clean the pot and then continue to cook, the remaining vegetables in the pot will easily burn, which also poses certain risks.

2. Turn off the range hood immediately after cooking: It may induce lung disease

Some people like to turn off the range hood immediately after cooking. However, this casual habit may be a dangerous one. If the fire is particularly high when cooking and the food is burnt, harmful substances will be released, which will harm the respiratory system and may induce lung disease. Therefore, it is best not to turn off the range hood immediately after cooking. In fact, it takes time for the range hood to expel exhaust gas, and there is still some unclean exhaust gas remaining in the kitchen after cooking. After cooking, you may want to let the range hood continue to run for 3 to 5 minutes to ensure that harmful gases are completely discharged.

3. Don’t put the oil in the pan until it smokes: Trans fatty acids are harmful to your health

How to tell if the oil is hot? Many people would answer that just seeing smoke coming out of the oil pan is enough. However, when the oil pan smokes, the oil temperature has often reached above 200℃. If you put the vegetables into the pan at this time, the substances produced will increase the risk of disease, and many nutrients in the vegetables will also be destroyed. Nutritionists recommend that during the cooking process, it is best to use a hot pan and cold oil. The trans fatty acids produced by oil at high temperatures are harmful to the human body.

4 Use the remaining oil for cooking

Many people are reluctant to throw away the fried oil and continue cooking. Experts recommend that cooking oil should be used only once, or at most 2 to 3 times while controlling the oil temperature. Oil that has been used many times will have residual pathogens in it, mainly benzopyrene, as well as some aldehydes, heterocyclic compounds, etc.
