After suffering from systemic lupus erythematosus, patients need to keep their mouths shut. They should not be greedy or eat nothing, which will easily lead to malnutrition. Patients with systemic lupus erythematosus should not eat more spinach, because spinach can increase proteinuria and cast of lupus nephritis. It can also cause urinary turbidity and urinary calculi (oxalate crystals), which is not suitable for patients and friends. Patients with systemic lupus erythematosus can't eat horse meat, donkey meat, mutton, dog meat and venison. Because these foods are warm, it will not only aggravate the internal heat symptoms of SLE patients. Moreover, it is clinically found that individual patients aggravate and induce patients' illness, resulting in adverse consequences. Patients with systemic lupus erythematosus should also pay attention. Patients can eat hot food, but it is not an absolute taboo. Be careful not to eat too much. For example: pepper, green pepper, leek, onion, garlic and so on. Some foods can cause photosensitivity, rash and facial erythema, and lupus patients should not eat them.
