Canola oil-based diets have been shown to reduce plasma cholesterol levels in comparison with diets containing higher levels of saturated fatty acids. Consumption of canola oil also influences biological functions that affect various other biomarkers of disease risk. Previous reviews have focused on the health effects of individual components of canola oil. Here, the objective is to address the health effects of intact canola oil, as this has immediate practical implications for consumers, nutritionists, and others deciding which oil to consume or recommend. A literature search was conducted to examine the effects of canola oil consumption on coronary heart disease, insulin sensitivity, lipid peroxidation, inflammation, energy metabolism, and cancer cell growth. Data reveal substantial reductions in total cholesterol and low-density lipoprotein cholesterol, as well as other positive actions, including increased tocopherol levels and improved insulin sensitivity, compared with consumption of other dietary fat sources. In summary, growing scientific evidence supports the use of canola oil, beyond its beneficial actions on circulating lipid levels, as a health-promoting component of the diet.
菜籽油饮食已被证明可降低血浆胆固醇水平,与含有较高水平饱和脂肪酸的饮食相比。菜籽油的消费还影响影响各种疾病风险生物标志物的生物功能。以前的综述主要集中在菜籽油个别成分的健康影响上。在这里,我们的目的是探讨完整菜籽油的健康影响,因为这对消费者、营养师和其他决定消费或推荐哪种油的人来说具有直接的实际意义。进行了文献检索,以研究菜籽油消费对冠心病、胰岛素敏感性、脂质过氧化、炎症、能量代谢和癌细胞生长的影响。数据显示,与其他膳食脂肪来源相比,总胆固醇和低密度脂蛋白胆固醇显著降低,以及其他积极作用,包括增加生育酚水平和改善胰岛素敏感性。总之,越来越多的科学证据支持将菜籽油用作促进健康的饮食成分,其益处不仅在于对循环脂质水平的有益作用。
