There is growing awareness of the complex link between nutrition and skin. In the last few decades, our understanding of this link has grown significantly with research findings from multiple laboratory, animal, and human studies. From the impact of diet on clinical features of aging skin, to documentation of the biochemical and histologic changes that occur, our understanding of this link continues to expand and evolve. In this paper, we review the research on the impact of diet on skin aging. A number of long-term observational population studies have documented that healthier diets are linked to fewer signs of skin aging. Animal and laboratory studies have elucidated the biochemical processes that play a large role in the development of these clinical findings. A number of studies have also reported on the role of specific dietary compounds in impacting these processes, whether by combating or potentiating these forces. This body of research serves as guidance in recommending nutritional strategies that can combat the skin aging forces of oxidation, inflammation, and glycation.
人们越来越意识到营养与皮肤之间存在复杂的联系。在过去几十年里，随着来自多个实验室、动物和人体研究的结果，我们对这种联系的理解有了显著增长。从饮食对老化皮肤临床特征的影响，到对所发生的生化和组织学变化的记录，我们对这种联系的理解不断扩展和演变。在本文中，我们回顾了饮食对皮肤老化影响的研究。一些长期的观察性人群研究表明，更健康的饮食与较少的皮肤老化迹象有关。动物和实验室研究已经阐明了在这些临床发现的发展中起很大作用的生化过程。一些研究还报告了特定膳食化合物在影响这些过程中的作用，无论是通过对抗还是增强这些作用。这一系列研究为推荐能够对抗氧化、炎症和糖化等皮肤老化因素的营养策略提供了指导。
