The effect of canola, sesame and sesame-canola oils on body fat and composition in adults: a triple-blind, three-way randomised cross-over clinical trial.

ABSTRACT

The present study aimed to examine the effect of replacing edible oils with sesame oil (SO), canola oil (CO) and sesame-canola oil (SCO) on body weight and composition in adults. Adults without any chronic diseases (n = 77) were entered a 4-week run-in period and then were randomised to receive SO, CO and SCO for their household use in 9-week intervention periods (separated by 4-week washout intervals). Anthropometric measurements, as well as body composition markers, were assessed at baseline, middle and after each intervention period. In total, 73 participants completed the study. Although significant time effects were seen for waist and hip circumference, waist-to-hip ratio, central obesity index, body adiposity index, muscle mass and body fat percent (ptime<.05), the treatment and treatment × time effects were not significant (p>.05). The present clinical trial revealed that CO, SO and SCO might not differently affect body fat and composition. Trial registration code IRCT2016091312571N6 (http//en.irct.ir/trial/12622).
