There are too few choices of liquid food after operation, that is, the exchange of rice soup, broth, milk and soybean milk, and the nutrition is simply not enough. I know this because my husband had an operation to let him eat liquid food, so I went to check how to make fish soup, thinking it was better than rice soup. As a result, I found that the protein content of the broth was actually very limited, only 1%-2%, and the rest was still. Milk sticks are also macromolecular protein, and their absorption rate is limited. My husband didn't like it either, so he started looking for nutrition, and sure enough, he found a good thing, that is, the compound peptide nutrient solution in the middle of the river. It is a small molecule protein nutrient solution with easy absorption and high absorption rate. Does not affect gastrointestinal health, and has good taste. Anyway, my husband's picky people didn't hold back. After drinking it, my husband's surgical wound healed well and asked someone who knew how to do it. It is said that the rich collagen oligopeptides in marine fish skin can promote the absorption of protein, which is good for wound healing. Moreover, wheat oligopeptide can improve the body's resistance and is really friendly to postoperative patients. You can buy it for your mother to try. Anyway, my husband just drank it.
