Don't wait until the oil smokes before putting food. At high temperature, the nutrients contained in oil will be destroyed, and many nutrients in vegetables will also be destroyed. Moreover, the generated lampblack contains a lot of harmful substances, which will increase the risk of cancer. It is best to heat the pan with cold oil. Heat the pot first, then pour in the oil and put the vegetables before the oil smokes.
3. after frying a dish, wash the pot and fry the next dish. Sometimes after we fry a dish, we think the pot is clean, so we don't wash it and fry the next dish directly. But in fact, there will be grease and food residue in the pan that has been fried. When you fry the next dish, you will produce a lot of carcinogens. Therefore, for the sake of our health, we must not give up washing the pot.
4. Put the right seasoning according to different dishes. There are various condiments now, so don't put a lot of condiments in every dish. And many seasonings contain salt, such as soy sauce, bean paste, chicken essence and so on. Therefore, when cooking, according to the characteristics of each dish, add the right amount of seasoning to reduce the amount of salt, otherwise not only the taste of the dish is bad, but also it will affect health.
5. Don't reheat the used oil. Many people think it is a pity to dump the oil in our fried food and reuse it. As we all know, after oil is heated many times, it will increase the risk of many diseases and bring a lot of harm to the body. It is best to avoid heating oil repeatedly, use less oil when cooking and eat less fried food. If you want to reuse the used oil, you can use it directly for cooking without heating, such as salads and fillings.
6. Don't turn off the range hood immediately after frying. The function of range hood is to remove the oil fume generated during cooking. This kind of oil fume contains a lot of harmful substances, which will do harm to people's health and may even induce lung cancer after inhalation. The range hood also takes time to work. After cooking, the lampblack is not completely discharged. We can continue to run the range hood for about 5 minutes after frying the vegetables to ensure that the harmful gases in the room are completely discharged.
