Registered Dietitians (RDs) promote nutrition practices and policies and can influence food consumption patterns to include nutrient dense foods such as beans. Although many evidence-based health benefits of bean consumption (e.g., cholesterol reduction, glycemic control) have been demonstrated, there is limited research on the knowledge, attitudes, and perceptions of RDs regarding the inclusion of beans in a healthy diet. To fill this existing research gap, this cross-sectional survey explored the perceptions, knowledge, and attitudes of 296 RDs in Arizona, USA, toward beans. The RDs largely held positive attitudes toward the healthfulness of beans and were aware of many health benefits. Some gaps in awareness were evident, including effect on cancer risk, intestinal health benefits, folate content, and application with celiac disease patients. RDs with greater personal bean consumption had significantly higher bean health benefit knowledge. Twenty-nine percent of the RDs did not know the meaning of 'legume', and over two-thirds could not define the term 'pulse'. It is essential that RDs have up-to-date, evidence-based information regarding bean benefits to provide appropriate education to patients, clients, and the public.
注册营养师（RD）推广营养实践和政策，并可以影响食物消费模式，包括摄入富含营养的豆类。尽管已经证明了豆类消费的许多基于证据的健康益处（例如降低胆固醇、控制血糖），但关于 RD 对将豆类纳入健康饮食的认识、态度和看法的研究有限。为了填补这一现有研究空白，这项横断面调查研究了美国亚利桑那州 296 名 RD 对豆类的看法、知识和态度。RD 对豆类的健康益处持有积极的态度，并且对许多健康益处有所了解。但一些方面的认知仍存在差距，包括对癌症风险、肠道健康益处、叶酸含量以及与乳糜泻患者的应用等方面。个人豆类摄入量较大的 RD 对豆类健康益处的知识明显更高。29%的 RD 不知道“豆类”的含义，超过三分之二的 RD 无法定义“豆科植物”一词。RD 必须掌握有关豆类益处的最新、基于证据的信息，以便为患者、客户和公众提供适当的教育。
