饱和脂肪酸与健康研究进展

饱和脂肪酸一向被认为是"坏"脂肪酸。然而,其在乳脂肪中所占比列为50%左右,这是否可以说明饱和脂肪酸除了提供能量外还有其他一些重要的生理功能?人体是一个复杂的动态平衡体,片面强调降低饱和脂肪酸摄入是不科学的。综述了饱和脂肪酸与肥胖症、心血管疾病、心脏病及糖尿病之间关系的研究新进展,以及饱和脂肪酸代谢及生理功能研究新发现。只有全面、科学、系统地了解饱和脂肪酸在人体内的各种作用,才能对各年龄段、各种生理状态的人群提供膳食建议。

Research advances in saturated fatty acid and health

It is universally acknowledged that saturated fatty acids are bad.However,mammalian milks,including human milk,contain 50% of their total fatty acids as saturated fatty acids.Is it possible that saturated fatty acids not only supply energies but also have other more important physiological functions? Human body is a complicated homeostasis,so it is not scientific to unilaterally emphasize to reduce the intake amount of saturated fatty acids.The progresses between adiposity,cardiovascular diseases,heart disease,diabetes and saturated fatty acids were summarized,and some new aspects on the metabolism and physiological functions of saturated fatty acids were introduced.Only when the actions of saturated fatty acids in human body are known comprehensively,scientificly,systemicly,can we suggest dietary for all kinds of age level and physiological status of people.
