All products tested by the state have production date, production place 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 only have one or two of them, which is also unqualified. There are some small shops like that around our school, and some foods sold there are three-no products. Now let me tell you a little story, which happened right beside me. In my previous class, there was such a classmate 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 buys is qualified or not, as long as he likes it. After a while, he suddenly felt uncomfortable. He vomited several times a day and often had 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 he also missed many classes. From then on, he never dared to eat those foods indiscriminately.
Now that everyone knows the disadvantages of eating three foods, 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 when you buy food, you must see if it is a three-no product. It costs only a few cents to buy some messy food, but it costs hundreds of dollars to treat diseases. What a big gap. I hope everyone will not lose big because of small.
For the health of you, me and him, when buying food, you must go to a large and regular supermarket, and read the brand clearly to check whether it is qualified food.
