As the saying goes, "illness comes from the mouth", diet is closely related to our physical health, but not only the choice of food, storage, cooking, etc. will also affect the health of the food in the final mouth.
I like the oil to smoke before serving.
Modern edible oil has a high degree of refining, less impurities, so the smoke point is relatively high, can reach more than 200, high temperature is easy to destroy some nutrients in food, oil is also more likely to produce all kinds of harmful substances, inhalation of too much oil smoke is also harmful to the respiratory tract, and the actual cooking does not need such a high temperature, so the hot pan can be used to warm the oil when stir-frying.
I love to use re-frying oil.
Edible oil will gradually oxidize after contact with air, resulting in a "hala smell", which is one of the manifestations of deterioration. At the same time, the heated oil will produce harmful substances, and repeated use will cause the harmful substances and coke food residues to accumulate more and more, and promote the oxidation of the oil, so the long-term use of refried oil has a certain impact on health.
Mineral water bottled with other spices.
In order to reduce the migration rate of harmful substances in the packaging, the manufacturer will adjust the raw materials and processes according to the nature of the contained items, although they are all plastics, but the water may not be able to fill the oil, and the unsuitable container to hold oil, vinegar, soy sauce and other seasonings may lead to a large number of harmful substances in the container to migrate to the food.
Do not turn on the range hood.
Oil smoke is an important risk factor for lung cancer in non-smokers, and the impact of oil smoke is more significant due to the use of high-temperature cooking in China. In order to reduce the intake of oil fumes, it is recommended to turn on the range hood before cooking, and then close it after 3-5 minutes after cooking.
Raw and cooked are not separated.
Raw food, especially meat and aquatic products, is likely to contain many pathogenic bacteria, parasites, etc., if raw and cooked food share a set of kitchen utensils, cross-contamination may occur, so it is recommended to be sure to separate raw and cooked food, do not mix.
