Abstract:
Dietary lipids are an essential source of nutrients in human nutrition, providing essential fatty acids and energy for the human body and maintenance of normal physiological activities. The intestinal tract plays an important role as the primary site for digestion and specific absorption of lipids. In this paper, based on the intestinal digestion pathway of lipids, the key factors influencing intestinal lipid digestion are discussed from various perspectives. These factors include lipid morphology, morphology changes due to protein-lipid interaction, lipid configuration changes, bile salt secretion, pancreatic lipase, and co-lipase. The interface effects affecting the key behaviors of lipid digestion were analyzed. The intestinal absorption mechanisms of dietary lipids were elucidated based on three perspectives: transport factor regulation, molecular absorption pathways, and indirect regulation and absorption of intestinal microorganisms. This research establishes a theoretical foundation for further functional modification, high-value utilization, and innovative research and development of dietary lipids.
