Studies of adults report that perceived taste affects food choices and intake, which in turn may have an impact on health. However, corresponding evidence on adolescents is limited. Our aim was to summarize current evidence of the impact of taste perception on food choice preferences or dietary intakes among adolescents (mean age 10-19.9 years). Systematic searches identified 13 papers, 12 cross-sectional and one cohort study published between 1 January 2000 to 20 February 2020 assessing the impact of taste (using phenotypic and/or genotypic markers) on food choices in adolescents without any disease conditions. Qualitative assessment in the current review indicated that individuals sensitive to bitter tastes often have a lower preference of bitter-tasting food and higher preference for sweet-tasting food. A meta-analysis of three studies on bitter-taste sensitivity revealed no difference in preference for bitter-tasting vegetables between bitter tasters and non-tasters (standardized mean difference (SMD) = 0.04; 95% CI: -0.18, 0.26; 0.72). Overall, a limited number of studies were available for review. As a result, we report no clear relationship between taste perception and food choices or intake in adolescents. More studies are needed to evaluate the link between adolescents' taste perceptions and dietary intake.
研究表明，成年人的味觉感知会影响他们对食物的选择和摄入，而这又可能对健康产生影响。然而，针对青少年的相应证据有限。我们旨在总结目前关于味觉感知对青少年（平均年龄 10-19.9 岁）食物选择偏好或饮食摄入量影响的证据。系统检索确定了 13 篇论文，其中 12 项是横断面研究，1 项是队列研究，发表时间为 2000 年 1 月 1 日至 2020 年 2 月 20 日，评估了味觉（使用表型和/或基因型标志物）对青少年无任何疾病状况下食物选择的影响。目前的综述定性评估表明，对苦味敏感的个体通常对苦味食物的偏好较低，对甜味食物的偏好较高。对 3 项苦味敏感性研究的荟萃分析显示，苦味接受者和非接受者对苦味蔬菜的偏好没有差异（标准化均数差（SMD）=0.04；95%CI：-0.18，0.26； 0.72）。总体而言，可用于综述的研究数量有限。因此，我们报告说在青少年中，味觉感知与食物选择或摄入之间没有明确的关系。需要更多的研究来评估青少年味觉感知与饮食摄入之间的联系。
