For patients with diabetic foot ulcers, first, their diet should control blood sugar. Foods with a high glycemic index like porridge, glutinous rice, and rice noodle rolls should be avoided. Additionally, sweet foods are also off-limits; it's important for meals to be regular and measured. Second, as patients with diabetic foot ulcers need nutrients for wound healing, they can eat foods high in protein such as eggs, fish, fish soup, and lean meats to promote wound healing. Third, if the patient also has high blood lipids, it's advisable to maintain a light diet and avoid greasy foods.
