The reason why northerners increase such a large share, regardless of average income, eating habits and other factors, is because of the high latitude and cold climate. The northeast is in the highest latitude area in the country, and it is really cold. According to the biological principle, the larger the individual animal, the smaller the relative body surface area, which is beneficial to heat preservation. Therefore, there will be a phenomenon that individuals in cold areas grow taller than individuals in warm areas within the same species.
Before the popularity of modern kitchens, the most popular cooking method in Northeast China was stewing. When we talk about the large size of food in Northeast China, we are actually talking about it.
Mainly stew. Cooking is fast and fuel-efficient, and there are too many things in the pot to cook. On the other hand, stews usually take an hour or two to stew. If there is too little stew, it will be considered "unworthy" The most important thing is that the average rural family is a cauldron. This pot should feed the whole family. For an hour or two, choosing to cook means choosing to walk around the stove, and choosing stew can stroll out and chat. Therefore, stew has never been a choice of rich taste, but a shrewd arrangement of life under the comprehensive consideration of material cost and time cost.
Maybe it's the pot. Cold and single raw materials form a sufficient condition for a large amount of food in Northeast China, but it is not a necessary condition. For example, many European countries also meet the requirements of cold salad and single ingredients, but they are not as exaggerated as Northeast cuisine. English food tastes terrible, but at least try hard. Although German food is also a big elbow with sauerkraut and sausage, it also abides by European sitcoms, with one person serving a large plate and avoiding several people serving a large basin.
