Disclosed herein are polar lipid mixtures, comprising glycerophospholipids such as phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylserine (PS) and phosphatidylinositol (PI), and sphingolipids such as sphyngomyelin (SM). Most importantly, the ratio of phospholipids in said mixture is comparable to that of HMF, and is represented by SM>；PC>；PE>；PS>；PI or SM=PC>；PE>；PS>；PI. Processes for the preparation of said mixtures and uses thereof are also described herein.
