What are the food safety hazards around us? short

First, the harm of chemically processed food. Many chemicals can cause cancer when they enter the human body. For example, the sulfur dioxide of day lily, yuba and candied fruit fumigated with sulfur dioxide exceeds the standard, and reacts with water to generate sulfurous acid after entering the human body. It is an oxidant, which will damage the liver and kidney of human body and cause cancer to human body. Excessive preservatives in food, such as many aromatic organic compounds, have carcinogenic effects. Professor Huang's foods processed by chemical substances are often invisible in appearance, and the harm of eating them will not appear in a short time, but it is a cumulative effect, which will lead to gene mutation and cancer in the human body after a long time.

Second, the harm of using antibiotics and hormones in animal breeding.

In the breeding of chickens, ducks, shrimps and other animals, the use of antibiotics such as chloramphenicol and furazolidone to sick animals will cause the antibiotic residues in animals to exceed the standard. After these residues accumulate in the human body to a certain extent, they will destroy human DNA and lead to gene mutation and cancer.

Clenbuterol, which is used for raising pigs, was originally a drug for treating asthma. I don't know who invented it to improve the lean meat rate of pigs. Eating too much can make people dizzy, sick and even die.

Third, the harm of fried food meat and grain will be polluted by heavy metals to a certain extent, but the content is very small. Similarly, a pot of oil is repeatedly used to stir-fry these meats and grains. Oil virtually becomes a "concentrator" for these heavy metal substances, so that more and more of these substances are dissolved in oil, and these substances enter the fried food and finally enter the human body, and these substances contain a lot of carcinogens.
