Food should be soft and easy to digest, light and palatable, and nutritious, because people's various functions are relatively low and their immunity is relatively low after surgery. First of all, we should enhance the immunity of patients and prevent wound infection. We can drink more raw fish soup and eat more radish, japonica rice and minced meat porridge! There are dried pork bean curd soup, steamed peeled chicken with medlar and so on. And then eat some natural nutritious food with the function of invigorating qi and tonifying deficiency. I wish the elderly an early health!
