Abstract

Objective: We aim to provide an overview and update the current documents regarding the effect of canola oil (CO) compared to other dietary oils on body weight and composition in adults.

Methods: PubMed, Scopus, Google Scholar, and ISI Web of Science were searched until Sepetember 2024 for randomized clinical trials (RCTs) that assessed the effect of CO on anthropometric measures.

Results: In this systematic review and meta-analysis thirty-two studies were included. CO consumption significantly increased WHR (MD: 0.003 cm, 95% CI: 0.001, 0.005, P value: 0.003) and significantly decreased BMI (mean difference (MD): -0.127 kg/m², 95% C: -0.231, -0.024, P value: 0.016) However, it did not significantly affect other anthropometric measures (P > 0.05). Based on subgroup analysis, CO supplementation significantly reduced BW in studies on T2DM patients, with parallel design, on patients over 50 years old and with a dose of more than 30 g/d. It also significantly increased WC in trials with parallel design and on hyperlipidemia patients. In addition, CO supplementation significantly increased WHR in the majority of subgroups.

Conclusions: Compared to other oil supplementation, CO could decrease BW, BMI and increase WHR, and WC in general or subgroup analysis. Further studies are needed to provide additional insight into how canola oil affects BW and composition in adults.

期刊介绍： Nutrition Journal publishes surveillance, epidemiologic, and intervention research that sheds light on i) influences (e.g., familial, environmental) on eating patterns; ii) associations between eating patterns and health, and iii) strategies to improve eating patterns among populations. The journal also welcomes manuscripts reporting on the psychometric properties (e.g., validity, reliability) and feasibility of methods (e.g., for assessing dietary intake) for human nutrition research. In addition, study protocols for controlled trials and cohort studies, with an emphasis on methods for assessing dietary exposures and outcomes as well as intervention components, will be considered. Manuscripts that consider eating patterns holistically, as opposed to solely reductionist approaches that focus on specific dietary components in isolation, are encouraged. Also encouraged are papers that take a holistic or systems perspective in attempting to understand possible compensatory and differential effects of nutrition interventions. The journal does not consider animal studies. In addition to the influence of eating patterns for human health, we also invite research providing insights into the environmental sustainability of dietary practices. Again, a holistic perspective is encouraged, for example, through the consideration of how eating patterns might maximize both human and planetary health.
