There is indeed a great difference in the food intake between the north and the south. On the whole, the food intake in the north is greater than that in the south.

First of all, geographical climate and other factors determine the regional product restrictions and eating habits. For example, I am used to seafood by the sea, and I like delicacies by the mountain. If the staple food is roughly and simply divided, the northern part is mainly pasta, the staple food is diversified, and the side dishes are simplified. The southern part loves rice, and the staple food is single, while the side dishes are diversified.

Although rice is the staple food in the south, the protagonist has always been a side dish. In many places, it can be said that dishes are used to accompany rice. For example, when you eat in southern Fujian, you will drink a bowl of soup first, while most of the soups in the south have a lot of exquisite ingredients, and then you can cook with dishes after drinking the soup. After a meal, the side dishes of a meal will normally have a variety of ingredients to 1 or 2 kinds, and the cooking method will be at least three or more. In this way, different cooking methods and rich ingredients add up to a strong satiety, so the dishes in the south are relatively small and delicate.

In the north, although the staple food is diversified, the ingredients and cooking are single. Steamed bread with pimples, steamed bread with sweet potato vermicelli soup, boiled miscellaneous grains porridge, pancakes and steamed noodles ... There are many staple foods with few patterns, and you will eat more unconsciously. Moreover, compared with the southern coastal areas, the diet in the north is heavier in taste, but many of them are not greasy. The single cooking of ingredients has a slow response to satiety, and the heavy taste is conducive to appetite. Therefore, the overall food intake in the north is greater than that in some areas in the south.

Topographically speaking, the north is located in a large plain area, so there are many manual workers, and northerners have a large appetite. Even if there is not so much manual labor now, the eating habits of northerners have been handed down from generation to generation, and it is difficult to change them in a short time. The southern region is mostly mountainous, and the weather is always rainy and humid, which will lead to loss of appetite. It is also difficult to store food in the southern weather, so southerners are used to cooking less and eating less.

in terms of climate, the weather in the north is cold, and the cold weather in the north is resistant to storage, so I buy more food every time I buy food. Southerners pay more attention to exquisiteness. Most people don't buy too much food, and southerners pay attention to collocation when cooking, and they don't do too much at once.

In fact, the difference of regional development level will also affect the difference of food intake, which is not divided into the north and the south, but of course, the overall food intake in the north is more. For example, the overall food intake of rural people is relatively greater than that of urban people. Simply put, the higher the level of economic and social development, the richer and more diverse people's diets, the more likely they are to feel full, and the less they eat.

We should have a correct attitude towards the food intake of the north and the south, which does not mean that all southerners eat very little. In fact, everyone's food intake is individual. It does not mean that southerners must eat less, but northerners must eat more. This is only to say that most people do, and there are many geographical and historical factors. Moreover, with the large population flow, their eating habits will change.
