健康的饮食对于促进青春期的健康和降低成年后的疾病风险至关重要。这突显了改善营养教育和增加获得更健康食物选择的必要性。然而，饮食数据的准确性对营养研究构成了巨大的挑战。我们利用并分析了一个通过高中公民科学项目收集的新的饮食记录数据集来解决这个问题。我们把重点放在营养素上，而不是食物类别上，以描述青少年的饮食模式。2019年至2021年全国健康与营养检查调查数据也进行了同样的分析，以进行比较。根据美国食品和药物管理局推荐的营养素日值(DV)，我们的公民科学数据集中的大多数食物的脂肪、纤维、钾、钙、铁、糖和胆固醇的日值都很低(即5%DV)。只有少数项目的宏量和微量营养素含量较高(即20%DV)。聚类分析确定了9个营养成分不同的食物集群，它们的大小差异很大。对NHANES数据的分析得出了类似的结果，但与公民科学数据集相比，高能量、高脂肪、高碳水化合物、高糖、高铁和高钠的食物比例更高。这项研究展示了公民科学项目在收集有价值的饮食数据和了解青少年营养摄入量方面的潜力。查明关键的营养缺口可以指导有针对性的营养教育和提供可获得的更健康的食物选择，从而在青春期及以后产生积极的健康结果。
A healthy diet is essential for promoting good health during adolescence and mitigating disease risks in adulthood. This underscores the need for improved nutrition education and increased access to healthier food choices. However, the accuracy of dietary data poses a significant challenge in nutritional research. We utilized and analyzed a novel dietary record dataset collected through a high school citizen science project to address this issue. We focused on nutrients rather than food groups to characterize adolescent dietary patterns. The same analyses were performed on the 2019–2021 National Health and Nutrition Examination Survey data for comparison. Based on the U.S. Food and Drug Administration’s recommended daily value (DV) for nutrients, the majority of food items in our citizen science dataset are low (i.e., <5% DV) in lipids, fiber, potassium, calcium, iron, sugar, and cholesterol. Only a minority of items are high (i.e., >20% DV) in macro and micronutrients. The clustering analysis identified nine food clusters with distinct nutrient profiles that vary significantly in size. The analyses on the NHANES data yielded similar findings, but with higher proportions of foods high in energy, lipids, carbohydrates, sugar, iron, and sodium compared with those of the citizen science dataset. This study demonstrates the potential of citizen science projects in gathering valuable dietary data and understanding adolescent nutrient intake. Identifying critical nutrient gaps can guide targeted nutrition education and the provision of accessible healthier food options, leading to positive health outcomes during adolescence and beyond.
