The timing and types of food people eat, along with daily fluctuations in in these parameters, are important factors influencing health and well-being. However, there is limited data on how eating patterns remain consistent over multiple days. To address this gap, we conducted an exploratory, observational analysis of over 20,000 adults, who recorded more than 2.5 million food logs collected over two weeks via the myCircadianClock app. Our analysis reveals significant variability in food timing and diversity. The time window during which 95% of food and beverages were consumed during the 2 weeks ranged from 10 hours 54 minutes for the lowest decile to over 16 hours for the highest. The median number of unique food and beverage items consumed over the two weeks varied from 20 to 86, but only a subset of these items was consistently eaten on multiple days. Many common foods were regularly consumed at specific times of the day, and factors like age, gender, and work schedules influenced both eating patterns and food choices. These findings provide a foundation for utilizing longitudinal food records in nutrition and lifestyle research to enhance our understanding of human behavior and health.
人们进食的时间和食物类型，以及这些参数的每日波动情况，都是影响健康和幸福的重要因素。然而，关于饮食模式如何在多天内保持一致的数据有限。为了填补这一空白，我们对2万多名成年人进行了一项探索性观察分析，这些成年人通过myCircadianClock应用程序记录了两周内收集的超过250万份食物日志。我们的分析揭示了食物进食时间和多样性存在显著差异。在这两周内，95%的食物和饮料被消耗的时间窗口从最低十分位数的10小时54分钟到最高十分位数的超过16小时不等。两周内食用的独特食物和饮料项目的中位数从20种到86种不等，但其中只有一部分项目在多天内被持续食用。许多常见食物在一天中的特定时间被规律食用，年龄、性别和工作时间表等因素会影响饮食模式和食物选择。这些发现为在营养和生活方式研究中利用纵向食物记录提供了基础，以增强我们对人类行为和健康状况的理解。
