TLDR Nutrition plays a key role in managing skin disorders, with specific dietary changes helping improve conditions like acne, dermatitis, psoriasis, alopecia, and skin cancer.
Chronic skin diseases often require more than pharmacotherapy due to adverse effects and metabolic comorbidities, with nutrition emerging as a critical factor in disease management through the gut-skin axis and immune homeostasis. While diet alone is rarely curative, precision nutrition is essential for optimizing patient outcomes. Specific dietary risks and interventions vary across conditions: high glycemic index foods and dairy increase acne risk; high sodium intake is linked to atopic dermatitis; ultra-processed foods affect psoriasis; and vitamin D deficiency is a risk for alopecia. Nutritional interventions like omega-3 fatty acids, probiotics, and vitamin D show promise but require further validation through large-scale randomized controlled trials. For skin cancers, nicotinamide is recommended for chemoprevention in certain patients, while high-fiber diets and probiotics improve outcomes in melanoma treatment. Future research should focus on diverse populations and standardized protocols to enhance the role of nutrition in dermatological care.
