Dry beans and soybeans are nutrient-dense, fiber-rich, and are high-quality sources of protein. Protective and therapeutic effects of both dry bean and soybean intake have been documented. Studies show that dry bean intake has the potential to decrease serum cholesterol concentrations, improve many aspects of the diabetic state, and provide metabolic benefits that aid in weight control. Soybeans are a unique source of the isoflavones genistein and diadzein, which have numerous biological functions. Soybeans and soyfoods potentially have multifaceted health-promoting effects, including cholesterol reduction, improved vascular health, preserved bone mineral density, and reduction of menopausal symptoms. Soy appears to have salutary effects on renal function, although these effects are not well understood. Whereas populations consuming high intakes of soy have lower prevalences of certain cancers, definitive experimental data are insufficient to clarify a protective role of soy. The availability of legume products and resources is increasing, incorporating dry beans and soyfoods into the diet can be practical and enjoyable. With the shift toward a more plant-based diet, dry beans and soy will be potent tools in the treatment and prevention of chronic disease.
干豆和大豆营养丰富、富含纤维，是优质的蛋白质来源。食用干豆和大豆的保护和治疗作用已有文献记载。研究表明，食用干豆有可能降低血清胆固醇浓度，改善糖尿病状态的多个方面，并提供有助于控制体重的代谢益处。大豆是异黄酮染料木黄酮和黄豆苷元的独特来源，它们具有多种生物学功能。大豆及大豆制品可能具有多方面的促进健康作用，包括降低胆固醇、改善血管健康、维持骨矿物质密度以及减轻更年期症状。大豆似乎对肾功能有有益影响，尽管这些影响尚未完全明确。虽然食用大量大豆的人群某些癌症的患病率较低，但确凿的实验数据不足以阐明大豆的保护作用。豆类产品和资源越来越多，将干豆和大豆制品纳入饮食既切实可行又令人愉悦。随着向更以植物为基础的饮食转变，干豆和大豆将成为治疗和预防慢性病的有力工具。
