食品法典委员会(CAC)通过了一个全面的膳食纤维(DF)定义(1)以反映对膳食纤维的了解现状，(2)认识到所有表现为纤维的物质，无论它们是如何生产的，如果它们显示出生理益处，都可以被命名为DF，以及(3)促进食品标签和食品成分表格的国际协调。这篇综述给出了DF假说提出后，DF方法和定义的改进所关注的DF知识状态的历史和演变。这些改进同时进行了干预性和流行病学研究，从而更好地理解了DF在促进各种不同的抗消化碳水化合物所赋予的众多生理益处方面的作用。将食典定义(包括其脚注授权将聚合物包括在DP 3-9中)和批准的食典第1类方法与其他现有定义和方法进行比较，将指出不同之处，并强调所有司法管辖区采用与食典一致的定义的重要性。这种统一使得能够比较世界各地的营养研究、建议、食品成分表和营养标签。我们将证明，纤维类似于维生素，因为它们在结构、功能和所需数量上各有不同，但每种纤维在适量存在时都有助于最佳健康。由于全世界膳食纤维的摄入量远低于推荐水平，认识到“所有纤维都适合”是通过授权和鼓励更多摄入含有固有和添加膳食纤维的食物来弥补“纤维差距”的重要策略。用添加的膳食纤维强化食物可以更容易地增加摄入量，同时将卡路里保持在推荐的水平。
A comprehensive dietary fiber (DF) definition was adopted by the CODEX Alimentarius Commission (CAC) (1) to reflect the current state of knowledge about DF, (2) to recognize that all substances that behave like fiber regardless of how they are produced can be named as DF if they show physiological benefits, and (3) to promote international harmonization for food labeling and food composition tables. This review gives the history and evolution of the state of DF knowledge as looked at by refinements in DF methods and definitions subsequent to the launch of the DF hypothesis. The refinements parallel both interventional and epidemiological research leading to better understanding of the role of DF in contributing to the numerous physiological benefits imparted by all the various digestion resistant carbohydrates. A comparison of the CODEX definition (including its footnote that authorizes the inclusion of polymers with DP 3–9) and approved CODEX Type 1 methods with other existing definitions and methods will point out differences and emphasize the importance of adoption of CODEX-aligned definitions by all jurisdictions. Such harmonization enables comparison of nutrition research, recommendations, food composition tables and nutrition labels the world over. A case will be made that fibers are analogous to vitamins, in that they vary in structure, function and amount needed, but each when present in the right amount contributes to optimal health. Since the intake of DF is significantly below recommended levels throughout the world, the recognition that ‘all fibers fit’ is an important strategy in bridging the ‘fiber gap’ by enfranchising and encouraging greater intake of foods with inherent and added DF. Fortifying foods with added DF makes it easier to increase intakes while maintaining calories at recommended levels.
