What effect does eating mutton skewers often have on health?

Kebab is a new landscape in the streets in recent ten years. There are many customers all year round, but it also causes serious environmental pollution, making the streets full of smoke and choking smell, which has become the pollution source of the city. Some people prefer mutton kebabs, and they always buy a few kebabs when they pass by the stall after work every day. Eating mutton skewers has become a habit and unhealthy.

Investigation shows that kebabs contain 3,4-benzopyrene. This compound comes into contact with the gastric mucosa after entering the stomach with food, which constitutes a risk factor for gastric cancer. Someone injected 3,4-benzopyrene into animal cortex, causing skin cancer, and injected it into muscle to cause sarcoma; The gastric lavage dose was only 10 mg, and 85% mice developed gastric cancer. Some people use smoked mutton to raise mice, and 5 of 45 mice have malignant tumors. When smoking barbecue, due to the incomplete combustion of charcoal, coal, sawdust and other substances, a large number of polycyclic aromatic hydrocarbons are produced, which pollutes food. Sometimes the content of 3,4-benzopyrene in food can reach 2.6~ 1 1.2 μ g/kg. According to sampling, a string of mutton skewers can contain 3,4-benzopyrene 1.03~4.00 micrograms. After 3,4-benzopyrene enters human body, it is transformed into pre-polycyclic aromatic hydrocarbon epoxide under the action of oxidase, which can combine with deoxyribonucleic acid, ribonucleic acid and protein in human cells, making normal cells abnormally cancerous.

Some street vendors use bicycle spokes as skewers and wear mutton skewers, which is more harmful to human health. The surface of bicycle spokes is chrome plated. Chromium can be absorbed by mutton skewers under high temperature fumigation. After eating with mutton, chromium accumulates in human tissues and organs, which is harmful to health. It is reported that some people in Britain conducted a survey on painters working in aircraft maintenance factories, and found that the incidence of respiratory cancer increased significantly among people who had been exposed to zinc chromate for more than 20 years. Mice inhaled calcium chromate dust once every 35 hours, which can cause pulmonary adenoma after a certain period of time.

Therefore, in order to reduce the intake of carcinogen 3,4-benzopyrene, we should eat less smoked and grilled food, eat less or not eat mutton skewers sold in the street, and don't eat mutton skewers worn by bicycle spokes, so as to avoid the chronic accumulation of these carcinogens in various tissues and systems in the body and gradually lead to the evil consequences of cancer.
