Although all surgeries are different and all patients unique, there are common components to every operation. For example, in all procedures, there is some degree of tissue disruption and a subsequent healing process. The healing process is greater in larger procedures, and smaller in lesser, more minimally invasive ones. But in all, there is a healing process.
To help the healing process, it is wise to eat foods which are rich in the building materials required for healing. Some important nutrients are glutamine, iron, Vitamin C, Vitamin B12, as these all, in specific ways, are crucial to the healing process.
Five foods that are high in these nutrients are raw green leafy vegetables, beets, beans, fish and poultry. As heat may break down some of the components, if at all possible, eat the vegetables raw. Of course, cook the fish and poultry.
