Dietary patterns have been shown to worsen or alleviate several dermatological diseases. A well-balanced, plant-based diet is known to have anti-inflammatory, probiotic, and antioxidant properties, along with weight loss-promoting effects. Moreover, a plant-based diet has a low glycemic load, improving metabolic disease. Due to these qualities, plant-based diets may have beneficial effects on inflammatory skin conditions. In this review, we aim to discuss the possible mechanisms by which a plant-based diet reduces disease severity in psoriasis, acne, hidradenitis suppurativa, and atopic dermatitis. We also aim to clarify how a plant-based diet may influence skin healing and identify sources of vitamins, nutrients, fatty acids, and protein in a well-balanced, plant-based diet. We performed a literature search on PubMed/MEDLINE databases with the following keywords: "plant-based" OR "vegan" OR "vegetarian" OR "meat" OR "diet" AND "psoriasis" OR "hidradenitis suppurativa" OR "acne" OR "atopic dermatitis" OR "skin healing" OR "dermatology". Our findings demonstrate that plant-based foods may improve inflammatory skin diseases by supporting the gut microbiome, exerting anti-inflammatory effects, providing barrier support, and improving glycemic control. With the proper education, there is an abundance of plant-based food sources or supplements that contain riboflavin, vitamin B12, vitamin A, omega-3 fatty acids, and protein, thereby ameliorating the risk of nutritional deficiencies. Thus, a plant-based diet may have therapeutic potential in dermatology. In spite of the evidence available, there is a paucity of clinical studies focusing specifically on plant-based diets and dermatologic conditions and further investigation is warranted.
饮食模式已被证明会加重或缓解多种皮肤病。众所周知，均衡的植物性饮食具有抗炎、益生菌和抗氧化特性，还有促进体重减轻的作用。此外，植物性饮食的血糖负荷较低，有助于改善代谢性疾病。由于这些特性，植物性饮食可能对炎症性皮肤病有有益影响。在本综述中，我们旨在探讨植物性饮食降低银屑病、痤疮、化脓性汗腺炎和特应性皮炎疾病严重程度的可能机制。我们还旨在阐明植物性饮食如何影响皮肤愈合，并确定均衡的植物性饮食中维生素、营养素、脂肪酸和蛋白质的来源。我们在PubMed/MEDLINE数据库中进行了文献检索，关键词如下：“植物性”或“纯素食”或“素食”或“肉类”或“饮食”以及“银屑病”或“化脓性汗腺炎”或“痤疮”或“特应性皮炎”或“皮肤愈合”或“皮肤病学”。我们的研究结果表明，植物性食物可能通过支持肠道微生物群、发挥抗炎作用、提供屏障支持和改善血糖控制来改善炎症性皮肤病。通过适当的教育，有大量富含核黄素、维生素B12、维生素A、ω-3脂肪酸和蛋白质的植物性食物来源或补充剂，从而降低营养缺乏的风险。因此，植物性饮食在皮肤病学中可能具有治疗潜力。尽管有现有证据，但专门针对植物性饮食与皮肤病状况的临床研究较少，有必要进一步研究。
