Jonathan Wolfe:本期节目讨论了ω-3脂肪酸和油性鱼类对健康的影响,以及近年来人们对ω-3脂肪酸有效性的质疑。他提出了一个问题:增加油性鱼类和ω-3脂肪酸的摄入是否真的有益于健康,还是仅仅是一个食物神话? Sarah Berry:她对ω-3脂肪酸的益处和有效性进行了详细的阐述,并指出该话题在科学界也存在争议。她解释了ω-3脂肪酸的类型(ALA、EPA、DHA),以及它们在人体中的作用和来源。她还讨论了流行病学研究和临床试验的结果,指出食用油性鱼类与降低心血管疾病风险相关,但补充剂的效果可能因剂量、类型、个体差异和基础疾病而异。她特别强调了高甘油三酯人群的益处,以及ω-3脂肪酸的抗炎作用。最后,她还讨论了养殖鱼类与野生鱼类的区别,以及整体健康饮食的重要性。 Sarah Berry:她详细解释了ω-3脂肪酸的类型、功能和来源,并指出人体可以将ALA转化为EPA和DHA,但转化率很低。她回顾了大量研究,包括流行病学研究和临床试验,指出食用油性鱼类与降低心血管疾病风险和死亡率相关,但补充剂的效果则存在争议。她分析了不同研究结果的差异,例如REDUCE-IT试验显示高剂量EPA ω-3脂肪酸有益,而其他荟萃分析则显示效果有限。她认为,ω-3脂肪酸的益处可能取决于剂量、类型、个体基线特征(如甘油三酯水平)以及是否服用他汀类药物等因素。她还强调了ω-3脂肪酸的抗炎作用,以及整体健康饮食的重要性。她最后指出,素食者和纯素食者虽然ω-3脂肪酸摄入量低,但心血管疾病风险也较低,这可能是因为他们整体饮食更健康。
