In terms of care for patients with advanced bowel cancer, besides eliminating physical pain to relieve suffering, food nutrition is also extremely important. Food is the source of energy for human body, especially for patients with advanced bowel cancer. It is very important to make a good combination and choice of food. What are the best things to eat in the late stage of bowel cancer? First of all, it depends on the patient’s condition and signs. If the patient is weak, he/she should be given some fluffy or liquid nutritious food such as rice soup, rice porridge or lotus root powder, etc. When the condition improves a little, he/she can eat general food. For patients with good appetite or no major digestive problems, we should pay attention to the reasonable combination of nutrition, eat more fresh vegetables and fruits to supplement dietary fiber and vitamins, and have a comprehensive diet, but pay attention to the fat content should not be too high, otherwise it will increase the burden on the digestive system. It is not good for the patient’s body. It is also important to remember that it is not advisable to eat a diet that stimulates the stomach and intestines, such as spicy and greasy food, as well as barbecue and fried food, and it is best not to eat cold, hard food. You should follow the principle of light and nutritious diet, and eat more green leafy vegetables such as asparagus, celery, leek, cabbage and radish, which can stimulate intestinal peristalsis and increase the number of bowel movements and facilitate the discharge of toxins as soon as possible. For patients with advanced bowel cancer, they should also consider their personal dietary preferences and try to meet their wishes, but when they ask for something such as smoking and drinking, they should be discouraged in time. We should pay attention to the patient’s diet and the number of bowel movements, and ensure a regular diet and sleep. This is the most basic step to ensure the patient’s physical condition.
