What should patients with central nervous system leukemia avoid eating?

Patients with central nervous system leukemia should avoid eating spicy, stimulating, greasy, or overly hard foods, as these may increase the burden on the digestive system and trigger or worsen adverse reactions such as nausea, vomiting, and abdominal distension. Additionally, patients should avoid soy sauce, allergenic foods, smoking, and alcohol consumption, to prevent unfavorable effects on their condition. Instead, patients are advised to consume foods that are high in calories, semi-liquid, easily digestible, and nutritionally rich, such as fresh fruits, vegetables, low-cholesterol foods, and iron-rich foods (e.g., peas, black beans, green vegetables, jujubes, brown sugar, black fungus, sesame paste, and egg yolks), to replenish necessary nutrients and promote recovery. Furthermore, patients should adopt a dietary pattern of eating small meals frequently to reduce the burden on the gastrointestinal tract and enhance nutrient absorption. Specific dietary arrangements should be adjusted according to the patient's medical condition and the physician's recommendations.
