Nutritional Clinical Studies in Dermatology

The document from 2011 reviews the role of nutrition in skin health and the progression of skin diseases, including acne, psoriasis, atopic dermatitis, and hair loss. It suggests that recent studies indicate a possible link between milk consumption and acne due to hormones affecting sebum production, though these studies have limitations. Nutrients like probiotics and omega-3 fatty acids may benefit atopic dermatitis and psoriasis, respectively. Nutrition is also important for hair health, with polyunsaturated fatty acids and zinc being beneficial. The document discusses the protective role of nutrients against UV damage and the manifestation of malnutrition in skin conditions. It emphasizes that skin symptoms can be early signs of nutritional deficiencies, with deficiencies in zinc, biotin, essential fatty acids, and protein being common. Eating disorders and obesity are associated with skin disorders, and nutritional supplements may improve skin health and appearance. The document concludes that nutrition is crucial for skin health, and dietary manipulation can help prevent and treat skin diseases, highlighting the importance of low-glycemic-index foods, probiotics, antioxidants, and other supplements for skin health.
