油脂营养成分及其对肠道健康影响的研究进展北大核心CSCD

油脂是人体最主要的营养物质之一,其消化吸收主要发生在肠道,而肠道内存在种类繁多的菌群,可以直接参与人体的消化吸收、脂质代谢、能量供应等。油脂的消化吸收可能与多种代谢紊乱和肠道疾病、糖尿病、肥胖等慢性疾病存在联系,而食用油脂摄入不平衡会影响肠道菌群组成和代谢,破坏肠道稳态,进而可能导致上述疾病的发生。综述了油脂的脂肪酸组成、功能性伴随成分及其对人体健康的影响,分析了近年来油脂对肠道菌群组成及其代谢产物影响的研究,并对未来的研究方向进行了展望,这对进一步开展油脂营养特性及其对肠道健康影响的研究以及合理膳食保障人体健康具有积极意义。

Progress on nutrient of oil and fat and its influence on intestinal health

Oil and fat is one of the most important nutrients for human body, and its digestion and absorption mainly occurs in the gut. A wide range of microbiota inhabiting in the gut can directly participate in the digestion and absorption, oil and fat metabolism and energy supply of the human body. The digestion and absorption of oil and fat may be associated with a variety of metabolic disorders and intestinal diseases, diabetes, obesity and other chronic diseases. The imbalance of edible oil and fat intake can affect the composition and metabolism of intestinal microbiota, and destroy the intestinal homeostasis, leading to the above diseases. Fatty acid composition, accompanying functional components of oil and fat and their effects on human health were reviewed, and the effects of oil and fat on intestinal microbiota composition and its metabolism in recent years were summarized. Based on these, the future research was prospected, which had a positive significance for the further study of oil and fat nutritional characteristics and its effect on intestinal health and reasonable diet to protect human health.
