The statement of “10 kinds of food that cannot be eaten by cancer” is unscientific, and there is no food contraindication for cancer patients under the premise of no allergy. Cancer is a general term for malignant tumors, the occurrence of which is closely related to genes, environmental pollution, genetic factors, irrational diet and smoking. Cancer patients generally do not have food taboos under the premise of no allergies. Since cancer consumes a lot of nutrients in the patient’s body, moderate consumption of some nutrient-rich foods such as beef and other high-quality protein-rich foods, fresh fruits and vegetables and other vitamin-rich foods has a certain nutritional value for the organism. If diagnosed with cancer, it is recommended to go to the medical oncology department as soon as possible, and standardize the treatment under the doctor’s guidance, so as not to delay the condition.
