Abstract：
BACKGROUND: Skin physiology seems to be influenced by dietary choices and body composition, although links between these factors remain poorly characterised. In the present manuscript, we elaborate on the potential relationships among food groups, body composition and skin physiology in omnivores and vegetarians.
METHODS: This cross-sectional observational study involved 181 participants, 129 omnivores and 52 vegetarians. The main functions of the skin measured in our laboratory were transepidermal water loss, deep and superficial epidermal hydration, skin elasticity, and carotenoid content. Skin variables obtained from different body regions were made comparable by a new Proportional Skin Index calculated to respect their relative representativity.
RESULTS: No statistical differences were found when comparing both groups\' body composition and skin variables from different body regions, with the exception of the skin carotenoid content significantly higher in the vegetarian group (p < 0.001).
CONCLUSIONS: Although dietary patterns significantly differed between groups, with vegetarians consuming fewer animal-derived products and more plant-based foods, multiple linear regression analysis revealed no differences or association between the dietary pattern and the skin physiology. These findings highlight the need for further research to elucidate the specific impact of diet and food groups and body composition on skin physiology.

摘要：
背景：皮肤生理似乎受到饮食选择和身体成分的影响，尽管这些因素之间的联系仍然缺乏表征。在目前的手稿中，我们详细阐述了食物群体之间的潜在关系，杂食动物和素食者的身体成分和皮肤生理。
方法：这项横断面观察研究涉及181名参与者，129个杂食动物和52个素食者。在我们实验室测量的皮肤的主要功能是经表皮水分流失，深层和浅表表皮水化，皮肤弹性,和类胡萝卜素含量。从不同身体区域获得的皮肤变量通过新的比例皮肤指数进行比较，以尊重它们的相对代表性。
结果：比较两组不同身体部位的身体成分和皮肤变量时，没有发现统计学差异，除皮肤类胡萝卜素含量明显高于素食组(p<0.001)。
结论：尽管各组之间的饮食模式存在显著差异，素食者消耗更少的动物源性产品和更多的植物性食品，多元线性回归分析显示饮食模式与皮肤生理之间没有差异或关联.这些发现强调了需要进一步研究以阐明饮食和食物组以及身体成分对皮肤生理的具体影响。
