Patients coming to me for treatment of leucoderma (Safed Dag on skin), ask different questions regarding precautions to be taken in food and most common question is whether white coloured food stuff causes spread of white patches on skin. Answer is, there is not any ill effect of eating white colour substances like milk, rice, etc. in vitiligo/safed dag disease. However, substances enrich with vitamin C , chemically contaminated food and allopathic drugs have to be avoided.
