炒菜油烟危害不容小觑
近日，一条关于炒菜油烟危害的热搜引发关注。专家指出，炒菜时将油烧至冒烟确实对健康不利。
当油温过高时，其中的不饱和脂肪酸会发生氧化裂解和异构化，产生反式脂肪酸。反式脂肪酸对人体健康有害，与心血管疾病、肥胖和某些癌症的发生有关。
此外，炒菜油烟还含有大量有害物质，如多环芳烃、甲醛和苯并芘等。这些物质具有致癌性，长期吸入可增加患肺癌、鼻咽癌等疾病的风险。
因此，炒菜时应避免将油烧至冒烟。建议使用低温烹饪方式，如蒸、煮、炖等。如果需要爆炒，应选择耐高温的油脂，如菜籽油、葵花籽油等。
同时，炒菜时应注意以下几点：
* 使用抽油烟机，并保持良好的通风。
* 避免长时间在油烟环境中停留。
*炒菜后及时清洗锅具和灶台，去除油污。
* 定期对抽油烟机进行清洗和保养。
通过采取这些措施，可以有效减少炒菜油烟对健康的危害，营造健康安全的烹饪环境。

The health risks of cooking fumes should not be underestimated.
Recently, atrending topic about the dangers of cooking fumes has sparked concern. Experts point out that heating oil to the point of smoking during cooking can indeed be detrimental to health.
When oil is heated to high temperatures, the unsaturated fatty acids in it undergo oxidative cleavage and isomerization, producing trans fatty acids. Trans fatty acids are harmfulto human health and are linked to cardiovascular disease, obesity, and certain types of cancer.
In addition, cooking fumes contain a large number of harmful substances, such as polycyclic aromatic hydrocarbons (PAHs), formaldehyde, and benzo[a]pyrene. These substances are carcinogenic, and long-term inhalation can increase the risk of diseases such as lung cancer and nasopharyngeal cancer.
Therefore, it is important to avoid heating oil to the point of smoking when cooking. It is recommended to use low-temperature cooking methods, such as steaming, boiling, and stewing. If stir-frying is necessary, choose heat-resistantoils such as canola oil or sunflower oil.
Also, pay attention to the following points when cooking:
* Use a range hood and maintain good ventilation.
* Avoid staying in a smoky environment for a long time.
* Clean cookware and stovetops promptly after cooking to remove oil stains.
* Regularly clean and maintain the range hood.
By taking these measures, the health risks of cooking fumes can be effectively reduced, creating a healthy and safe cooking environment.
