Dietary considerations for patients with lupus erythematosus include: eating a balanced diet rich in calories, proteins, and vitamins; avoiding irritating, greasy, and photosensitive foods. Lupus erythematosus is an autoimmune disease. Its cause is not yet clear, and it may be related to factors such as genetics, ultraviolet rays, infection and drugs. In their daily diet, lupus erythematosus patients can choose foods rich in calories, proteins and vitamins that are easy to digest, such as eggs, cucumbers, meat, apples, milk and so on. In addition, Lupus erythematosus should avoid irritating and greasy foods, such as chili peppers, peppercorns, and fatty meats. People with lupus erythematosus are more sensitive to light, so it is recommended to avoid photosensitizing foods such as snow peas, fennel, radish leaves, mango and pineapple. Once diagnosed with lupus erythematosus, it is recommended that patients go to the hospital in a timely manner and receive standardized treatment under the guidance of a doctor.
