消耗富含ω-3的葡萄籽油降低了心血管疾病的风险

格拉纳达大学的一个科学家团队及其合作者表明,使用富含ω-3的芥花籽油(改良形式的油菜籽,含有少于2%的芥酸)降低了心血管疾病的风险。 研究人员再次证实,ω-3是胆固醇代谢的有效调节剂。这一次,科学家分析了来自84位志愿者患者的血浆,他们在吃不同类型具有不同脂肪酸组成的油之后,呈现至少一种代谢综合征的症状。 他们发现ω-3脂肪酸降低血浆中的PCSK9浓度。PCSK9是与血液中高水平的LDL胆

格拉纳达大学的一个科学家团队及其合作者表明,使用富含ω-3的芥花籽油(改良形式的油菜籽,含有少于2%的芥酸)降低了心血管疾病的风险。

研究人员再次证实,ω-3是胆固醇代谢的有效调节剂。这一次,科学家分析了来自84位志愿者患者的血浆,他们在吃不同类型具有不同脂肪酸组成的油之后,呈现至少一种代谢综合征的症状。

他们发现ω-3脂肪酸降低血浆中的PCSK9浓度。PCSK9是与血液中高水平的LDL胆固醇和其他心血管疾病相关的蛋白质。富含ω-3的卡诺拉油的消耗不仅显着降低了甘油三酯的浓度,而且与其它饮食相比,血浆中PCSK9蛋白浓度也显着降低(10%)。

蛋白质的作用机制基于LDL胆固醇受体的破坏,阻止细胞摄取LDL,并增加其血浆浓度,导致动脉粥样硬化和其他相关疾病的风险增加。

来自卡诺拉油多中心试验干预(COMIT)的这些结果代表了从饮食摄取不同类型的脂肪后,PCSK9蛋白血浆浓度变化的第一线科学证据。

最后,CeliaRodríguez说:“尽管不同脂肪酸对PCSK9血浆浓度的作用机制正在调查中,我们不应该忘记膳食脂肪在预防心血管疾病风险中的重要性”。
