All products tested by the state have production date, place of origin and shelf life. Such products are qualified and reliable. The so-called "three no foods" means that there is no production date, no production place and no shelf life. Maybe some foods are only one or two of them, and they are also unqualified. There are some small shops like that around our school, where some foods are three-no products. Now I'll tell you a little story, which happened around me. There was such a classmate in my previous class who liked to buy all kinds of snacks. And those foods are three no foods. Every time he passes those small shops, he wants to buy something to eat. He never cares whether the food he bought is qualified, as long as he likes it. After a while, he suddenly felt sick. He vomits several times a day and often has a stomachache. His mother took him to see a doctor, who said it was caused by eating unsanitary things. As a result, in order to treat the disease, he didn't come to school for several weeks and missed many classes. From then on, he never dared to eat those foods indiscriminately.
Now that everyone knows the disadvantages of eating three kinds of food, please don't buy those foods in the future. If you see a bright little food, don't buy it either, because it contains too much pigment. In addition, I remind you that buying food must be based on whether it is a three-no product. It only costs a few cents to buy some messy food, but it costs hundreds of dollars to treat diseases. The gap is so big. I hope everyone will not lose big because of small things.
For the sake of your health and mine, when buying food, you must go to a large regular supermarket to buy it. You must read the trademark clearly and check whether it is qualified food.
