Role of lentils (Lens culinaris L.) in human health and nutrition: a review

Humans have known lentils (Lens culinaris L.) since the dawn of civilization. The current work is a comprehensive review of lentils composition, nutritional value, and health benefits. The article addresses major proteins identified in lentils and their bioactive peptides, including lectins, defensins, and protease inhibitors. In addition, this review discusses the complex carbohydrate fractions in lentils, particularly the resistant starches, oligosaccharides, and dietary fibers with emphasis on their biomedical properties. Also, the current review discusses minerals and vitamins as well as the non-nutritive bioactive phytochemicals of lentils which add to the promising potential for clinical applications in the management and prophylaxis of several chronic human illnesses. The article finds out that various potential health benefits have been described for lentils such as anticarcinogenic, blood pressure-lowering, hypocholesterolemic and glycemic loadlowering effects. The proposed mechanisms behind each health benefit are discussed.
