The objective of this study was to evaluate the effect of addition of phytosterol on palm oil among metabolic syndrome (MetS) subject. This study was a clinical trial with randomized double blind controlled design. Thirty adult subject (age 40—60) with MetS are divided into 2 groups. Intervention group were given palm oil enriched with 6.5% phytosterol and used as cooking oil for habitual use for 8 week. The control group were given palm oil without phytosterol. Nutrition intake was assesed by recalls every 2 weeks. Blood lipid profile, blood glucose and anthropometry were analyzed at pre and post intevention. After 8 week intervention, estimated total palm cooking oil and phytosterol consumption on intervention group were 46±23 g/day and 2±1 g/day. There were no significant change of the LDL-choleseterol level (p>0.05) but there were a significant reductiton of serum total cholesterol and triglyceride level compared the control group (respectively p=0.007 and p=0.027). In conclusion with high level palm cooking oil intake, estimated phytosterol intake had reached the target and there are slight improvement of the lipid profile on MetS subject.
