Confusion around the terms "legumes" and "pulses" has been a long-standing problem among consumers, health professionals, and researchers in the United States. The Food and Agricultural Organization defines pulses as legumes that are harvested solely as dry grain and include beans, peas, chickpeas, and lentils. For the first time ever, the 2020-2025 Dietary Guidelines for Americans recognized and used the terminology "pulses." Correct terminology usage is important to build a solid research foundation that is specific to pulses, primarily because of their unique nutritional attributes that impact health differently than other legumes. Future widespread conformity and standardized use of a definition and categorization system around pulses versus legumes in research would allow for an improved interpretation of science and a better understanding of current research gaps. Clarity around these gaps could enhance and improve dietary recommendations, including the ability to refine our current understanding of the optimal daily or weekly intake of pulses at which health benefits are maximized.
在美国，消费者、健康专业人士和研究人员长期以来一直对“豆类”和“豆科植物”这两个术语感到困惑。粮食及农业组织将豆类定义为仅作为干谷物收获的豆类，包括豆类、豌豆、鹰嘴豆和小扁豆。有史以来第一次，2020-2025 年美国人饮食指南认识到并使用了“豆科植物”这一术语。正确使用术语对于建立一个专门针对豆科植物的坚实研究基础非常重要，主要是因为它们独特的营养特性对健康的影响与其他豆类不同。未来在研究中广泛采用和标准化豆类与豆科植物的定义和分类系统，将有助于更好地解释科学，并更好地了解当前的研究差距。明确这些差距可以增强和改善饮食建议，包括能够细化我们目前对最佳每日或每周豆类摄入量的理解，从而最大程度地获得健康益处。
