Sainfoin (Onobrychis viciifolia Scop.) and fenugreek (Trigonella foenum‐graecum L.) are two legumes that are being developed as forage crops in Canada with potential benefits for animal and human health. Sainfoin, a perennial crop containing condensed tannins (CTs), is gaining popularity in western Canada because of its benefits for cattle. Its CTs make the crop bloat‐free for grazing cattle while improving protein digestibility and reducing greenhouse gas emissions. The CT‐containing fenugreek is also considered as a bloat‐free annual forage legume that was developed to serve in short‐term crop rotations in western Canada. These crops are known to provide health and nutritional benefits to cattle with their high protein content and other beneficial nutraceuticals such as crude fiber, 4‐hydroxyisoleucine, steroid sapogenins, and galactomannans. Some of these nutraceuticals have the potential to benefit human health; however, such attributes have not been studied enough to harness the full potential of these legume crops in Canada. Recent research suggests that legumes are a healthy substitute for meat. However, metabolite analysis of sainfoin is mostly limited to proteins and CTs. The CTs reported in sainfoin are involved in reduction of blood pressure and detoxification and providing anticancer properties in humans. Recent studies on fenugreek have highlighted the beneficial nutraceuticals associated with human health but most of those claims are not backed by relevant clinical studies. In this article, we reviewed the nutritional quality attributes of sainfoin and fenugreek and assessed their potential as functional foods and nutraceuticals for animal and human health based on scientific evidence.

加拿大的皂素和胡芦巴作为饲料和功能食品

皂素（Onobrychis viciifolia Scop。）和胡芦巴（Trigonella foenum‐graecumL.）是两种豆科植物，正在加拿大作为草料作物开发，对动物和人类健康具有潜在的好处。皂素是多年生作物，其中含有浓缩的单宁（CTs），由于对牛群有益，因此在加拿大西部越来越受欢迎。它的CT可以使农作物放牧无牛，同时提高了蛋白质的消化率并减少了温室气体的排放。含CT的胡芦巴也被认为是一种无膨胀的一年生牧草，被开发用于加拿大西部的短期作物轮作。已知这些作物以其高蛋白含量和其他有益的营养保健品（如粗纤维，4-羟基异亮氨酸，类固醇皂苷元和半乳甘露聚糖）为牛提供健康和营养益处。其中一些营养保健品有可能有益于人类健康。然而，对此类属性的研究还不足以充分利用加拿大这些豆类作物的全部潜力。最近的研究表明，豆类是肉的健康替代品。然而，皂素的代谢物分析主要限于蛋白质和CT。皂素中报道的CTs涉及降低血压和排毒并在人类中提供抗癌特性。胡芦巴的最新研究强调了与人类健康相关的有益营养保健品，但其中大多数主张均未得到相关临床研究的支持。在本文中，我们回顾了皂素和葫芦巴的营养品质属性，并根据科学证据评估了它们作为动物和人类健康的功能性食品和营养保健品的潜力。
