Since roadside stalls are placed on both sides of the road, dust and various debris will inevitably stick to the food. Moreover, the items at roadside stalls have not been disinfected and will lead to a large number of bacteria after repeated use. In today's hot weather, their food is not kept in the refrigerator. It has been exposed to the sun for a long time, and most of it has deteriorated. Many children will have diarrhea after eating, such as the following roadside stalls.

First, stinky tofu. Stinky tofu contains a large amount of ferrous sulfate, which will corrode the human intestines, and the odor emitted by stinky tofu is inherently putrefactive and moldy, which is a strong carcinogen. Moreover, stinky tofu contains Clostridium botulinum, which is one of the most toxic proteins. After eating, the toxins will harm people's nerves, with disastrous consequences. They will not only cause diarrhea, but also destroy the body's defense system.

Second, grilled skewers. Whether it is mutton skewers or squid, the protein will be destroyed under the action of high-temperature frying. Carcinogens such as heterocyclic amines and polycyclic aromatic hydrocarbons will be produced and adhere to food surfaces.

Moreover, the meat skewers are all stale meat and contain a lot of parasites. Even if the outside meat is cooked, the inside meat may not be cooked. This parasite is very deadly. Once it enters the human body, it is a trivial matter to cause diarrhea, and it will multiply wildly and cause cancer.

Third, Malatang. Malatang has always been regarded as junk food. If the temperature is too high, it will easily form gastric mucosa. In addition, in order to maintain the freshness of Malatang, the ingredients contain forma. This substance can irritate the human intestines, damage the human liver, and cause gastroenteritis. Regular consumption can easily induce cancer, and the harm should not be underestimated.

In short, no matter what kind of roadside food, there is no nutritional value at all, and their harm far exceeds their own nutrition. Moreover, children's intestinal systems are already very weak, so they cannot eat these junk foods. If they cannot control it, then eat as little as possible.
