COMPARISON OF PALM, PALMSTEARIN, PALMOLEIN, AND PARTIALLY HYDROGENATED SOYBEAN OILS - EFFECTS ON SERUM-LIPIDS AND FECAL FATTY-ACID EXCRETIONS OF ADULT HUMANS

We studied the effects of the different forms of saturated (palm, palm olein, palmstearin) and polyunsaturated (partially hydrogenated soybea n oil) oil diets on serum lipids and fecal fatty acid excretions of hu mans. Each oil was the dominant fat in diets (20% of total dietary fat ) consumed by II normolipidemic, live-in individuals. Test diets were assigned by randomization. All four diets had similar influence on TC, LDL-C, HDL-C and phospholipid (PL), with significant VLDL-C changes o bserved for palmstearin when compared with partially hydrogenated soyb ean oil. The fecal fat excretion was higher (2.8 g/d) with palm (P) an d palmstearin (PS) and lower (2.25 g/d) with palmolein (PO) and hydrog enated soybean (HSO) diets. However, excretion of palmitic acid did no t change significantly with any of the palm oil diets. More palmitic a cid (C16 : 0) was excreted when PS diet was fed compared to the feedin g of HSO diet. The changes between the two diets reached statistical s ignificance (P < 0.05). We concluded that there were no significant di fferences in serum lipid concentrations and in fecal fatty acid excret ions due to alterations in dietary fats.
