开发新的膳食评估方法：myfood24焦点

摘要(中文译文)

传统的膳食测量方法，主要是食物频率问卷，已不再适用。膳食具有复杂性，英国超市中可获得的食品种类超过15万种。本综述描述了以往使用的营养评估方法的局限性，并概述了利用新技术的最新方法，包括在线工具myfood24。膳食评估方法的局限性包括回忆偏倚；无法估算份量大小；在不同人群中缺乏适应性；以及食物成分数据不足。新工具包括用于实时摄入追踪的移动应用程序；利用基于图像的方法进行份量估算和食物识别；传感器技术，如智能餐具和咀嚼计数器。在线平台为大规模流行病学研究提供了一种经济的方法。myfood24是一款为研究开发的在线工具，并已使用生物标志物进行验证。myfood24已在超过27个国家的25万余名研究参与者中取得成功；它也被用于医疗保健、学生教育及其他场景。myfood24注重数据的准确性和参与者使用的便捷性。由营养学家管理的底层食物成分数据库比标准的通用数据表缺失数据更少，营养素变量更多。该数据库包含膳食质量和可持续性指标。一款新应用程序包含新颖的myfood24膳食优化引擎，可针对个人提出膳食改变建议以达到营养目标。新的膳食评估工具可提供更准确的数据，并对膳食行为提供更深入的洞察。它们需要被用于大规模流行病学调查、公共卫生人群筛查以及患者中，以充分发挥其潜力。

Abstract

Traditional methods of measuring diet, mainly food frequency questionnaires, are not fit for purpose. Diet is complex, with over 150k different food items available in UK supermarkets. This review describes the limitations of nutritional assessment methods used in the past. It provides an overview of recent methods using newer technologies, including online tool myfood24. Limitations of dietary assessment methods include recall bias; inability to estimate portion sizes; lack of adaptability across diverse populations; and inadequate food composition data. New tools include mobile apps for real-time intake tracking; use of image-based approaches for portion sizes and food identification; sensor technologies such as smart utensils and bite counters. Online platforms provide an economical approach for large-scale epidemiology. myfood24 is an online tool, developed for research and validated using biomarkers. Having demonstrated success with >250,000 research participants in over 27 countries; myfood24 is also used in healthcare, for student education and other settings. myfood24 focuses on accurate data and ease of participant use. The underlying food composition database curated by nutritionists has fewer missing data and more nutrient variables than standard generic tables. The database includes diet quality and sustainability measures. A new app includes the novel myfood24 Diet Optimization Engine suggesting individual dietary changes to meet nutrition targets. New dietary assessment tools provide more accurate data with deeper insights into dietary behaviour. They need to be used in large epidemiological surveys; for public health population screening and with patients to fully realise their potential.
