Effects of Fried Foods Prepared in Palm Oil Blended With Canola Oil Containing Surfactants and Green Tea Extract

Effects of Fried Foods Prepared in Palm Oil Blended With Canola Oil Containing Surfactants and Green Tea Extract on Postprandial Triglyceride Levels: A Double-blinded Randomized Controlled Clinical Trial

The objectives of the study were to investigate effects of foods prepared in palm oil blended with canola oil containing surfactants and green tea extract on postprandial triglyceride levels in healthy volunteers. There were 22 subjects in the study. They were divided into 2 groups: 1.comsumed foods fried in palm oil blended with canola oil containing surfactants and green tea extract and 2.comsumed foods fried in palm oil. Postprandial triglyceride, lipid profiles, and liver and kidney functions were evaluated before and after taking 5 hours.
