Ruminant meat (RM) is an excellent source of high-quality protein, B vitamins and trace minerals and plays an important role in global food and nutrition security. However, nutritional guidelines commonly recommend reduced intake of RM mainly because of its high saturated fatty acid (SFA) content, and more recently because of its perceived negative environmental impacts. RM is, however, rich in heart healthy cis-monounsaturated fatty acids and can be an important source of long-chain omega-3 (n-3) fatty acids in populations with low fish consumption. In addition, RM is a source of bioactive phospholipids, as well as rumen-derived bioactive fatty acids including branched-chain, vaccenic and rumenic acids, which have been associated with several health benefits. However, the role of bioactive RM lipids in maintaining and improving consumers’ health have been generally ignored in nutritional guidelines. The present review examines RM lipids in relation to human health, and evaluates the effectiveness of different feeding strategies and possibilities for future profile and content improvement.

反刍动物（RM）是优质蛋白质，B族维生素和微量矿物质的极佳来源，在全球食品和营养安全中起着重要作用。但是，营养指南通常建议减少RM的摄入量，这主要是由于其高饱和脂肪酸（SFA）含量，最近是由于其对环境的负面影响。然而，RM富含心脏健康的顺式-单不饱和脂肪酸，并且可能是长链omega-3（n-3）鱼类消费量低的人群中的脂肪酸。此外，RM是生物活性磷脂以及瘤胃衍生的生物活性脂肪酸（包括支链，牛痘和瘤胃酸）的来源，它们与多种健康益处有关。但是，营养指导原则通常忽略了具有生物活性的RM脂质在维持和改善消费者健康中的作用。本综述检查了与人类健康相关的RM脂质，并评估了不同喂养策略的有效性以及未来轮廓和含量改善的可能性。
