Sebum content, skin hydration and acidic skin pH are major factors in maintaining skin health. Various nutrients are reported to influence skin health, but the effect of dietary patterns (DPs) on skin health is unclear. In this study, we considered the DPs associated with these three skin health parameters in 84 healthy adults aged 19⁻37 years. Dietary intake was assessed using a food frequency questionnaire (FFQ) and skin health parameters were determined on the forehead of each subject. Among the four DPs extracted from the FFQ, DP2, characterized by a high intake of cereals, potatoes and starch, saccharides and fish and shellfish, was negatively associated with skin hydration. DP3, characterized by a high intake of potatoes and starch, seeds and nuts, fruits and eggs, was positively associated with acidic skin pH only before adjusting for potential confounders. On the other hand, DP4, characterized by a low intake of beans, and a high intake of meats, dairy products and beverages and alcohol, was negatively associated with acidic skin pH and positively associated with sebum content. The data stratified by sex revealed a negative association between skin hydration and DP2 in males and a negative association between sebum content and DP3 and a positive association between sebum content and DP4 in females. In conclusion, we demonstrated that specific DPs were associated with sebum content, skin hydration and pH in healthy Korean adults and that those associations were affected by sex.
皮脂含量、皮肤水分和皮肤 pH 值是维持皮肤健康的主要因素。有报道称，各种营养物质会影响皮肤健康，但饮食模式 (DPs) 对皮肤健康的影响尚不清楚。在这项研究中，我们考虑了与这三个皮肤健康参数相关的 DPs，共纳入 84 名年龄在 19-37 岁之间的健康成年人。饮食摄入情况通过食物频率问卷 (FFQ) 进行评估，皮肤健康参数则在每个受试者的前额进行测定。在从 FFQ 中提取的四个 DPs 中，DP2 以高摄入量的谷物、土豆和淀粉、糖类和鱼贝类为特征，与皮肤水分呈负相关。DP3 以高摄入量的土豆和淀粉、种子和坚果、水果和鸡蛋为特征，仅在调整潜在混杂因素之前与皮肤 pH 值呈正相关。另一方面，DP4 以低摄入量的豆类和高摄入量的肉类、乳制品、饮料和酒精为特征，与皮肤 pH 值呈负相关，与皮脂含量呈正相关。按性别分层的数据显示，男性皮肤水分与 DP2 呈负相关，女性皮脂含量与 DP3 和 DP4 呈负相关，皮脂含量与 DP4 呈正相关。总之，我们表明特定的 DPs 与健康韩国成年人的皮脂含量、皮肤水分和 pH 值有关，且这些关联受到性别的影响。
