China is the country with the most population in the world, and it is also the country with the most foodies in the world. Chinese food can be said to be extensive, profound and has a long history.

Chinese food has a wide range of influence. It is not only loved by many people in China, but also sought after by many people in the United States, South Korea, Japan and other places. There is even a famous "Chinatown" in the United States, which contains many Chinese

Restaurants, Americans often choose to eat at Chinese restaurants during festivals.

There are many types of Chinese food, such as fried dumplings, fried dough sticks, braised pork, lion heads, steamed pork ribs with glutinous rice, etc. So does anyone know how fried dough sticks are made?

In fact, fried dough sticks are a kind of food that has been fried at high temperatures. Usually, deep-fried dough sticks require a lot of oil. Once fried, the oil will be wasted if thrown away. If not thrown away, it will have adverse effects on the body.

Let’s take a look now. Can the oil used in fried foods be reused for cooking?

Everyone should know that the oil used for frying food can actually be divided into two types. One is the oil left after frying food once, and the other is the oil left after frying food repeatedly, which is what people use.

Commonly known as "gutter oil".

Of course, as we all know, gutter oil can cause great harm to the human body. It contains a large amount of disease-causing and carcinogenic substances, that is, triglycerides.

If people eat vegetables fried with gutter oil, it will be very bad for people's health.

Because when gutter oil enters the human body, it will destroy the white blood cells and the mucous membrane of the digestive tract, and the person will suffer from food poisoning. If the condition worsens, the person is likely to suffer from cancer. This is the result of eating gutter oil.

The consequences may be very dire, which is why the state has banned the use of gutter oil in the catering industry.

In addition to gutter oil, there is also oil left after frying food only once. This kind of oil cannot be said to be completely unusable, but it is not recommended for people to use a large amount.

This kind of oil is not as harmful to the body as gutter oil, but there are still certain harmful substances.

Because vegetable oil is not heat-resistant, the acid contained in the oil will rise when heated, and trans fatty acids and toxic oil oxidation products will easily be produced. People who eat such oily vegetables are at risk of developing cancer.

The possibility also increases.

Some people may think that it would be too wasteful to throw away all these oils after only using them once. So what should we do?

In fact, this kind of oil does not have to be thrown away, but it is necessary to avoid secondary high-temperature heating to avoid producing more carcinogens.
