Ulcerative colitis is a type of chronic nonspecific inflammation. Care measures include dietary care and emotional regulation. In terms of diet, it is best to eat at home as much as possible, eat less takeout and street food, and maintain a regular, nutritious diet with foods that are high in protein and calories, such as lean meats and eggs. It's also important to eat plenty of vegetables like cabbage and carrots, and avoid spicy, stimulating, and cold foods. During acute episodes, a light diet should be maintained to reduce irritation to the gastrointestinal tract. Additionally, attention should be paid to emotional regulation. Patients should maintain a positive and optimistic attitude, which is beneficial for the treatment and prognosis of ulcerative colitis.
