Prof. Tim Spector: 橄榄油,特别是特级初榨橄榄油,对健康有很多益处,包括降低患心脏病、中风和癌症的风险。这些益处主要源于橄榄油中丰富的单不饱和脂肪酸和多酚。多酚是强大的抗氧化剂,可以滋养肠道菌群,从而改善心血管健康、降低炎症反应,并增强免疫力。大量研究,包括PREDIMED研究,都证实了橄榄油的健康益处。市面上存在一些关于橄榄油的误导性信息,例如说橄榄油不适合烹饪,但这些说法都是不准确的。 Elizabeth Berger: 橄榄油的品质差异很大,特级初榨橄榄油是品质最高的等级,其多酚含量也最高。橄榄油的品质与橄榄的成熟度、采摘时间、加工方式和储存方式等因素密切相关。选择橄榄油时,应注意查看标签上的信息,例如产地、收获日期、是否经过过滤等。新榨橄榄油的多酚含量最高,保质期约为18个月,开瓶后应尽快食用。不同产地和品种的橄榄油风味不同,可以根据个人喜好和菜肴搭配选择合适的橄榄油。 Jonathan Wolff: 本期节目讨论了橄榄油的健康益处、不同等级橄榄油的区别、橄榄油的储存和烹饪方法以及如何选择高质量的橄榄油。通过与专家的访谈,我们了解到橄榄油对健康有很多益处,但要获得最佳效果,需要选择高质量的特级初榨橄榄油,并采取正确的储存和烹饪方法。
