It is possible to eat sage fruit after rectal cancer surgery, but it should be consumed in moderation so as not to irritate and affect the patient’s digestive system. The diet of patients after undergoing rectal cancer surgery should be regular and quantitative, with more high protein and fiber-rich foods, such as fruits and vegetables. Virgin fruit contains a large amount of vitamin C and carotene and other nutrients, which are helpful in strengthening the immune system, so it is possible to consume it in moderation. Postoperative patients of rectal cancer should pay attention to not consuming excessive amounts of hollies. Virgin fruit contains fruit acid, if consumed in large quantities, it may cause certain stimulation to the stomach and intestines, causing excessive secretion of gastric acid, leading to acid reflux, vomiting and other phenomena, which is unfavorable to the patients’ postoperative recovery. If abdominal discomfort such as abdominal pain or bloating occurs after consuming cherry tomatoes and does not improve for a long period of time, the patient should consult a doctor in time.
