? Waste oil? What are the disadvantages? Waste cooking oil is very harmful to human body, and its toxic substances can lead to diarrhea, indigestion and even gastric cancer. Through this news, many people are exposed to all kinds of food problems they have seen during this period, such as heavy metal rice flour, lean meat powder, milk powder with additives and so on. And can't help but sigh that the food problem seems to be getting more and more serious. In fact, the food problem has not become more serious. On the contrary, with the continuous improvement of people's requirements for quality of life and the increasingly developed national economy, food issues have become a key regulatory direction in China.
Why are food safety issues repeatedly banned? The reason why we often see such news is because the Internet is developed and the information is particularly open. Some news once uploaded can attract the attention of netizens. Especially since the rise of the media, food safety has been supervised by government departments, and has embarked on the road of government supervision as the mainstay and public supervision as the supplement. A lot of news was discovered by the public and exposed on the internet, and then the relevant departments responded quickly. Moreover, it is precisely because people attach importance to food safety that many people pay special attention to food safety exposed on the Internet, which leads to more and more false appearances of food safety problems.
The secret of delicious old oil lies in trans fatty acids. Almost all fried foods on the market contain trans fatty acids. The longer the oil is used, the more trans fatty acids are produced. People's taste buds especially welcome this substance. It can send a delicious signal to the brain through the strong stimulation of taste bud cells, and then it will make you eat a lot of this food. The same is true of gutter oil, which not only contains a lot of trans fatty acids, but also contains a lot of carcinogens such as benzopyrene, aldehydes and other heterocyclic compounds. In addition, it also contains heavy metal toxic substances such as arsenic and lead. Once the illegal edible oil is consumed in excess, it may cause cancer and do great harm for a long time.
