For patients with gastric cancer, there are no specific dietary taboos, except for avoiding foods that are too spicy or greasy, such as fried foods and barbecued items that are difficult to digest. Additionally, it is advisable to avoid carbonated and very cold foods that may irritate the stomach. The dietary approach should focus on eating smaller, more frequent meals that are easy to digest and bland. However, it is also important to ensure a balanced diet that includes both meat and vegetables to ensure adequate nutrition for the patient.
