The staple food in the north is mostly pasta. My northern classmates like steamed bread or wowotou with several dishes for lunch, while I am rice. Besides, there is no soup, which is the difference. Growing up in the south, there is usually a soup on the table, which is rare in the north, but some people will choose porridge instead of soup.
Not many people eat spicy food in the north, but it is necessary for many people in the south to eat spicy food. In addition, the climate between the north and the south is very different, and the ingredients are also very different. Vegetables in the north are rare. There are many high-fat and high-calorie ingredients in winter, such as mutton and beef. Because of eating these things, they are stored in the human body to resist the cold in winter. Winter in the south is not so cold, and the diet changes little all year round.
