Daily diet may have implications for skin ageing. However, data on the relationship between diet and the parameters of skin conditions are scarce. The present study aimed to examine the associations of biophysical properties of the skin of women with intakes of fats and antioxidant micronutrients as well as food groups as sources of these nutrients. In a cross-sectional study, we measured the hydration, surface lipids and elasticity of the skin of 716 Japanese women using non-invasive techniques. The extent of facial wrinkles in the crow's-foot area was determined by observation using the Daniell scale. Each subject's usual diet was determined with the use of a validated FFQ. After controlling for covariates including age, smoking status, BMI and lifetime sun exposure, the results showed that higher intakes of total fat, saturated fat and monounsaturated fat were significantly associated with increased skin elasticity. A higher intake of green and yellow vegetables was significantly associated with a decreased Daniell wrinkling score. Intake of saturated fat was significantly inversely associated with the Daniell wrinkling score after additional adjustment for green and yellow vegetable intake. Further studies with more accurate measurement methods are needed to investigate the role of daily diet in skin ageing.
日常饮食可能对皮肤衰老有影响。然而，关于饮食与皮肤状况参数之间关系的数据却很少。本研究旨在探讨女性皮肤的生物物理特性与脂肪和抗氧化微量营养素摄入量以及这些营养素来源的食物组之间的关系。在一项横断面研究中，我们使用非侵入性技术测量了 716 名日本女性的皮肤水分、表面脂质和弹性。使用 Daniell 量表通过观察来确定鱼尾纹区域的面部皱纹程度。使用经过验证的 FFQ 确定每个研究对象的日常饮食。在控制了年龄、吸烟状况、BMI 和终生日照暴露等协变量后，结果表明，总脂肪、饱和脂肪和单不饱和脂肪的摄入量越高，皮肤弹性越大。摄入更多的绿色和黄色蔬菜与 Daniell 皱纹评分降低显著相关。在进一步调整绿色和黄色蔬菜摄入量后，饱和脂肪摄入量与 Daniell 皱纹评分呈显著负相关。需要进一步的研究，采用更精确的测量方法，以探讨日常饮食在皮肤衰老中的作用。
