1. Effects on liver and lung function

Inhalation of oil smoke has obvious effects on lung function of healthy people and chronic bronchitis patients, which shows that the PEFR, V76, Vso, V25 are significantly decreased, chronic bronchitis group FVC and FEVI are also significantly reduced, inhalers cough, chest tightness, shortness of breath and other symptoms, indicating that oil smoke on the respiratory tract stimulation effect is the airway constriction, respiratory resistance increased. , shortness of breath and other symptoms, indicating that the irritating effect of oil smoke on the respiratory tract is airway constriction and increased respiratory resistance. Lung function was examined in eight logical non-smoking volunteers after short-term (1 hour) exposure to high concentrations of cooking fumes, and a significant decrease in lung capacity was found compared with pre-exposure.

2. Lipid peroxidation damage

Acute and chronic inhalation of cooking fumes can lead to an increase in MDA content and a decrease in SOD activity in the blood, lung, and liver tissues of experimental rats. A survey of occupational groups exposed to cooking oil fumes found that their plasma lipid peroxides (LPO) content was elevated, while plasma VitC, VitE, 9-carotene content, erythrocyte SOD activity, and snow glutathione were significantly reduced compared with non-exposure. It indicates that cooking oil can not only cause lipid peroxidation in vivo, but also reduce the activity of antioxidant substances and enzymes.

3. Mutagenicity

A large number of studies have shown that there are cytogenetic substances in cooking fumes that can cause gene mutation, chromosome damage, NDA damage and other biological effects, and are definitely mutagenic. Its genotoxicity is related to the composition of food, the type of cooking oil and the cooking temperature, and its mutagenicity increases with increasing temperature. Cooking oil fumes in some mutagenic substances are also carcinogenic, of which benzopyrene, volatile amine nitrite, heterocyclic amine compounds, etc. is known to be mutagenic, carcinogenic.

4. Human exposure to soot and tumors

There is no direct evidence of carcinogenicity of human exposure to soot, but the results of some epidemiological surveys show that soot is a suspicious factor in the occurrence of nasopharyngeal carcinoma and lung cancer. In case-control studies in Canada, the United States, the United Kingdom and Denmark, it has been found that chefs in the catering industry are at greater risk of lung, nasopharyngeal and esophageal cancers. Cooking fumes are a suspected factor in the development of lung cancer, and exposure to kitchen fumes is also a risk factor for nasopharyngeal cancer.

Women's lung cancer is on the rise, and high-temperature fumes are the culprit. Shanghai University of Traditional Chinese Medicine, led by Professor He Yumin "lung cancer" group research shows that young and middle-aged women in the kitchen cooking for a long time exposure to high-temperature fumes, will make their risk of lung cancer increased by two to three times.

Because of the kitchen cooking high-temperature fumes produce toxic fumes, so that the local environment deterioration, toxic fumes long-term stimulation of the eyes and throat, damage to the respiratory system cells and tissues, if not protected, it is very easy to make the high incidence of lung cancer.

Shanghai Cancer Institute released the incidence of malignant tumors survey data show that lung cancer has become the Shanghai population morbidity and mortality rate accounted for the first malignant neoplasms, female patients with cancer incidence rate of lung cancer after breast cancer accounted for the second, and the mortality rate also accounted for the first.

5. Skin roughness and wrinkles, hair loss

Smoke particles block the skin pores, resulting in female skin roughness, wrinkles, pigmentation middle-aged women are more prone to obesity, long-term exposure to fumes, the hair will be dry, fall out. Women are smoked by oil smoke into a yellow face.

6. Loss of appetite, mental anhedonia

Oil smoke invades the respiratory tract, can cause loss of appetite, upset, mental anhedonia, drowsiness, fatigue and other symptoms, medically referred to as oil smoke syndrome.

7. Great harm to the family

The teenager is in the stage of physical development, the oil smoke no one makes the teenager prone to chronic keratitis, rhinitis, pharyngitis, bronchitis, pneumonia and other diseases, seriously jeopardizing the health of children.
