The first time I read Hitler's biography, when I saw that "Hitler was so poor that he could only survive on bread, butter, and milk," my brain froze for a few seconds.

I continued reading and saw that the "homeless shelter" provided by the Weimar government had 24-hour hot water, free coffee, free lunch, and desserts, and I gently closed the book.
Before the Industrial Revolution in the 18th century (during the Qianlong period), an ordinary farm worker in Hampshire, England, had the following daily meal plan: breakfast: milk, bread, leftover salted pork from the previous day; lunch: bread, cheese, a small amount of beer, pickled pork, potatoes, cabbage or radishes; dinner: bread and cheese.
On Sundays, they could eat fresh pork.
Although European livestock farming was more developed, cheese production and preservation involved significant losses, making it roughly on par with eggs in terms of food.
I can still understand cheese being comparable to tofu in Japan, but comparing cheese to Chinese tofu might be a bit of an insult.
Chinese farmers of the same period, not to mention meat, couldn't even afford pure rice flour, relying only on foods like sweet potatoes and corn to fill their stomachs.
In years of disaster, they had to sell wives and children to survive.
In some areas, disaster victims had nothing to eat but tree bark, and some even ate dirt. Meanwhile, Japan was short on oil and fish; due to religious and productivity reasons, they ate plain rice with small fish at every meal, and tofu was considered a delicacy.
But at least they could ensure the supply of white rice; China truly couldn't even guarantee sweet potatoes.
A very counterintuitive point—per capita grain possession in various dynasties: Qin and Han 985 jin, Sui and Tang 988 jin, Song Dynasty 1,457 jin, Ming Dynasty 1,192 jin, and during the Qianlong years, it dropped directly to 780 jin.
