Enrollment: 10
Study Start Date: August 2009
Study Completion Date: September 2009
Primary Completion Date: September 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: palm olein Dietary Supplement: The acute effects of dietary fat on lipid profile, insulin sensitivity and inflammatory markers
Experimental: olive oil Dietary Supplement: The acute effects of dietary fat on lipid profile, insulin sensitivity and inflammatory markers
Experimental: lard Dietary Supplement: The acute effects of dietary fat on lipid profile, insulin sensitivity and inflammatory markers

Detailed Description:

A randomized, single blind, crossover design was undertaken to test meals enriched with palm olein vs olive oil vs lard. Volunteers were asked to participate in three postprandial challenges, separated by at least 3-days. Subjects were provided a low fat meal(<10g fat) the day before the intervention. Fasting blood was collected the next day and the subjects were instructed to consume test meals (50g high fat meal). Further venous blood was collected at 30 min, 1h, 2h, 3h and 4h postprandially.

Primary outcome variable: Triacylglycerol (TAG) Secondary outcome variables: Insulin sensitivity (glucose, insulin), non esterified fatty acids (NEFA), inflammatory markers
