Patients with throat cancer need to pay attention to the following aspects in their diet: First, it is recommended to adhere to a light diet, avoiding particularly greasy foods and opting for high-protein, low-fat foods. Second, it is recommended to eat soft or semi-liquid foods, and avoid particularly hard foods, as hard foods may cause swallowing obstructions and potentially damage the mucous membranes of the throat. Third, it is advised not to eat cured products and to reduce the intake of salty foods, as these foods may exacerbate the condition of throat cancer and potentially lead to cancer in other parts of the body.
