: Exploring emerging dietary patterns, such as plant-based diets (PBD), often requires considerable effort to rebuild new systems or adapt existing food classification frameworks, presenting a substantial challenge for dietary research. Current systems were not originally designed for this purpose and vary in standardization and interoperability, complicating cross-study comparisons. This study aimed to adopt the harmonized, food description-incorporated, food classification system (HFDFC system) to develop a plant-based diet food classification system (PBDFC system), and to evaluate dietary intake and nutritional status among adults in Taiwan. : A repeated cross-sectional design was applied using 24 h dietary recall data from the Nutrition and Health Survey in Taiwan (2013-2016 and 2017-2020), accessed via the national food consumption database. Adults aged 20-70 years were included. Data were processed through the HFDFC system to generate the PBDFC system. For each participant, the Plant-Based Diet Index (PDI), Body Mass Index (BMI), and Nutrient-Rich Food Index (NRF) were calculated and analyzed by age group. : Adults aged 46-70 had significantly higher O-PDI and H-PDI scores, lower Lh-PDI scores (all < 0.0001), and higher NRF values. Despite higher average BMI, those in the highest H-PDI tertile had significantly lower BMI ( < 0.02). : The HFDFC-based PBDFC system offers a flexible, scalable framework for plant-based diet classification and supports future cross-national research.
探索新兴的饮食模式，如植物性饮食（PBD），往往需要付出巨大努力来重建新系统或调整现有的食物分类框架，这给饮食研究带来了巨大挑战。当前的系统最初并非为此目的而设计，在标准化和互操作性方面存在差异，使得跨研究比较变得复杂。本研究旨在采用统一的、纳入食物描述的食物分类系统（HFDFC系统）来开发植物性饮食食物分类系统（PBDFC系统），并评估台湾成年人的饮食摄入量和营养状况。：采用重复横断面设计，使用通过国家食物消费数据库获取的台湾营养与健康调查（2013 - 2016年和2017 - 2020年）中的24小时饮食回忆数据。纳入20 - 70岁的成年人。数据通过HFDFC系统进行处理，以生成PBDFC系统。对于每位参与者，计算植物性饮食指数（PDI）、体重指数（BMI）和营养丰富食物指数（NRF），并按年龄组进行分析。：46 - 70岁的成年人的O - PDI和H - PDI得分显著更高，Lh - PDI得分更低（均<0.0001），NRF值更高。尽管平均BMI较高，但H - PDI三分位数最高的人群BMI显著更低（<0.02）。：基于HFDFC的PBDFC系统为植物性饮食分类提供了一个灵活、可扩展的框架，并支持未来的跨国研究。
