Leek is a very popular food. In China, whether in the south or the north, leek is a heartfelt love. Chefs also processed leeks into various delicacies, such as leek meat buns, leek scrambled eggs, leek fried noodles, grilled crucian carp, roasted leeks and leek boxes, which made people drool at the thought.

As we all know, leek is actually a kind of food with great side effects, especially after eating and drinking, burping with leek flavor can be said to be a dying taste. In addition, leek has another nickname called "intestinal grass". Sometimes, after eating, people can't help running to the toilet. However, leeks are still very popular.

But for most students, eating leeks in the school cafeteria is more difficult than winning 5 million lottery tickets. Many netizens want to know why most school canteens prohibit students from eating leeks. Does it affect your study? The answer is even more unexpected. First of all, the first reason must be the smell of leeks. After eating leeks, whether you go to the classroom or dormitory, these two places are relatively closed spaces. The air is not circulating. After eating leeks, the taste often affects others' study and life, but this is not the most important reason. The root cause is that leeks are too difficult to preserve.

What are the most common vegetables in the canteen? There is no doubt that potatoes, radishes and cabbages can be preserved for a long time, while leeks must be processed and sold quickly, otherwise the taste will soon decline or even deteriorate. Therefore, not only can you not eat leeks at school, but there are also many delicious vegetables.
