My mother-in-law always forces me to drink some soup and water, saying that it will facilitate lactation. Is it true?

The reason why the soup is white is not because the soup is nutritious, but because the fat in pig trotters, chicken, bones and other foods emulsifies after a long period of high temperature and turns into tiny fat particles, which makes the soup watery. It looks whiter. In addition, no matter adding vinegar or stewing for a long time, the nutrients in the ingredients cannot flow into the soup, so the nutrients of the milk soup are mainly in the ingredients of the soup. Milk soup cannot increase breast milk, but it is very effective in increasing weight.
