Lymphoma patients can eat beef unless they have allergy, if there is no other contraindication. 1. Beef belongs to a kind of food rich in high quality protein, and patients with lymphoma, who do not have obvious clinical manifestations such as nausea, vomiting, loss of appetite, aversion to grease and bloating, etc., should eat beef appropriately to replenish nutritional deficiencies in the body, which can help recovery of the physical state. Especially when receiving chemotherapy (cyclophosphamide, vinblastine, etc.) and radiotherapy, eating beef and other diets rich in high quality proteins can improve the physical condition and make the body in a better state to meet the next anti-tumor treatment. 2. If the patients themselves are allergic to beef, they should not consume it. If lymphoma is diagnosed, it is recommended to go to the hospital in time for consultation and standardized and reasonable treatment under the doctor’s guidance.
