Chickpeas, common beans, dry peas, and lentils are pulse crops that have been a cornerstone of the human diet since the inception of agriculture. However, the displacement of pulses from the diet by low fiber protein alternatives has resulted in a pervasive deficiency referred to as the dietary fiber gap. Using an analytical method American Association of Analytical Chemists (AOAC) 2011.25 that conforms to the Codex Alimentarius Commission consensus definition for dietary fiber, the fiber content of these pulse crops was evaluated in seed types used for commercial production. These pulse crops have 2 to 3 times more fiber per 100 g edible portion than other dietary staples. Moreover, there is marked variation in fiber content among cultivars of the same crop. We conclude that pulse crop consumption should be emphasized in efforts to close the dietary fiber gap. The substantial differences in fiber content among currently available cultivars within a crop can be used to further improve gains in fiber intake without the need to change dietary habits. This provides a rationale for cultivar-based food labeling.
鹰嘴豆、普通菜豆、干豌豆和小扁豆是豆类作物，自农业起源以来一直是人类饮食的基石。然而，低纤维蛋白质替代品在饮食中取代了豆类，导致了一种普遍存在的缺乏现象，即膳食纤维缺口。采用符合食品法典委员会膳食纤维共识定义的美国分析化学家协会（AOAC）2011.25分析方法，对这些豆类作物用于商业生产的种子类型中的纤维含量进行了评估。这些豆类作物每100克可食用部分的纤维含量比其他主食多2至3倍。此外，同一作物的不同品种之间纤维含量存在显著差异。我们得出结论，应强调食用豆类作物以缩小膳食纤维缺口。同一作物目前可用品种之间纤维含量的巨大差异可用于在无需改变饮食习惯的情况下进一步提高纤维摄入量。这为基于品种的食品标签提供了理论依据。
