Seborrheic dermatitis is a chronic papular and scaly superficial inflammatory skin disease that occurs in areas where sebum is secreted, and may be accompanied by varying degrees of itching. The causes of this disease are generally believed to be related to increased sebum secretion or changes in its chemical composition, as well as colonization and infection by Malassezia. Additionally, factors such as mental stress, diet, alcohol consumption, deficiency in B vitamins, emotional tension, fatigue, and infections can all affect the occurrence and development of the disease to varying degrees. Therefore, clinically, patients are generally advised to limit their intake of polysaccharides and fats, avoid spicy and irritating foods, abstain from alcohol, and eat more vegetables and fruits. As for eggs, we can eat them with confidence.
