Patients with gastric cancer are recommended to eat foods with high protein and vitamins, such as fish, shrimp, milk, fresh fruits and vegetables, and avoid spicy, greasy, raw and cold, smoked, baked and salt-pickled foods. These foods contain irritating ingredients and nitrites, which have strong stimulating effect and carcinogenic effect on gastric mucosa. Patients with gastric cancer should also pay attention to dietary rules and hygiene, and avoid overeating. Patients with gastric cancer should also pay attention to small and multiple meals, avoid high-calorie and high-sugar foods at each meal, and gradually transition from liquid diet to semi-liquid diet and then to normal diet.
