This is the power of businessman's advertisement. For European and American milk, the early stage is only a necessity, just like the crabs eaten by the poor in Shanghai in the 1920s. There is no special significance (and the milk at that time was actually leftovers after extracting cream). It was really popularized during World War II. Before the innovation of preservation technology, milk was only a regional food, and even many people simply ate cheese instead of milk. The so-called "a glass of milk a day makes a strong country" is just a meaningless slogan. You believe, you lose.

If you have a stomach that grows to 200, absorption is no problem. As long as you eat enough meat, it is really impossible to buy protein powder milk. The price in protein is too high. According to the lean weight of 70kg, half a catty of lean meat, five whole eggs, 15 egg white, one or two packs of milk is enough. You must first ensure that half a catty of meat and egg white are added slowly as you grow up.
