In our usual work, we often meet patients after bowel cancer surgery who ask: Doctor, how can I pay attention to my food in the future? Are there any dietary taboos? Especially, they like to ask: Are those “hairy things” not allowed to be eaten? The “hairy things” mentioned by patients basically refer to chicken, seafood and so on, even eggs are not exempted, and some patients really told me: she does not eat eggs, only duck eggs. Therefore, I feel the need to talk about this topic with patients and friends. In fact, there is no need to be so nervous, the so-called “hairy food” will lead to the recurrence of cancer that is just a kind of folk misinformation, a kind of “pseudo-science”. “Hairy food” is a concept in Chinese medicine, but if you look up any Chinese medical textbook, you will not find the saying that eating “hairy food” will lead to recurrence of cancer. In fact, the “hairy food” in Chinese medicine refers to food that may cause allergy after eating, for example, if someone is allergic to seafood, then seafood is “hairy food” for him/her. Any kind of food has its corresponding nutritional value, and those “hairy food” is in fact very rich in protein, as long as you are not allergic to it, and eat in moderation after surgery, it is a very beneficial supplement to the loss of protein and other nutrients due to the trauma of surgery and the side effects of chemotherapy. So, is it possible to eat as much as you want after bowel cancer and other digestive tract surgeries? I will now talk about my personal views on this issue: unlike other parts of malignant tumors, there are still some places that need to be paid attention to the diet of digestive tract malignant tumors after surgery. In my opinion, foods that increase the burden of digestive function should be avoided as much as possible for at least six months after surgery. For example, sticky food such as glutinous rice products (e.g. siu mai, dumplings), hard food such as nuts (melon seeds, peanuts, walnuts), corn, and individuals even need to avoid some traditional snacks such as mung bean cake and moon cake. Because the patient after surgery, gastrointestinal peristalsis, secretion and other digestive functions are weak, coupled with the factors of intestinal adhesions caused by the operation, eating such food is difficult to digest, “stagnation” in the intestines, causing abdominal distension and abdominal pain, or even intestinal obstruction. I have also encountered many patients who had eaten such food, resulting in intestinal obstruction, and had to come to the emergency room for medical treatment, and some of them even needed surgery to relieve the obstruction. In vain, they suffered physical pain which could have been avoided. Another common misconception is excessive “tonic”, today a turtle, tomorrow a sea cucumber, in fact, this so-called “tonic” nutritional value is not necessarily higher than ordinary food. Just in the previous era of material scarcity, people’s living conditions are poor, the usual nutrition can not keep up with, only in the case of serious illness to eat relatively high nutritional value of some of the “tonic”, now we are living conditions are good, the usual food in the nutrients I think is already enough, do not have to excessive “tonic! I don’t think there is any need to overdo the “tonic”. There is also a phenomenon that needs attention, especially some elderly patients and friends, easy to listen to some people or commercial organizations to buy a lot of “health care products” at high prices. Many of the so-called health products, the price is very high, but not as high as its advertised medicinal or nutritional value, and even some of them have not been through the State Food and Drug Administration and other management departments of the audit and authorization, on the illegal inflow of the market. So especially advise all elderly patients and friends, in the face of a dazzling variety of “health care products”, must remain vigilant, not blind faith.
