Jonathan Wolf:饱和脂肪的健康影响存在争议,公众对此感到困惑。一些研究表明高饱和脂肪摄入与多种疾病、死亡率和发病率增加相关,而另一些研究则表明全脂乳制品可能降低心脏病、2型糖尿病和骨质疏松症的风险。 在讨论中,Jonathan Wolf 强调了公众对饱和脂肪益处和害处的困惑,以及饱和脂肪在各种食物中的存在,并提出了一个关键问题:饱和脂肪是像我们一直被告知的那样有害的超级反派吗?他引导讨论,探索饱和脂肪的复杂性以及其对健康影响的细微差别。 Dr. Sarah Berry:脂肪是人体必需的营养物质,对能量供应、维生素吸收和细胞构建至关重要,缺乏脂肪会危及生命。脂肪的种类繁多,其分子长度和双键数量是区分不同脂肪的关键因素,这些差异决定了脂肪的特性和对健康的潜在影响。单不饱和脂肪对健康有益,多不饱和脂肪是人体必需脂肪酸。饱和脂肪也存在多种类型,其对健康的具体影响取决于其分子长度。动物性脂肪通常富含饱和脂肪,植物性脂肪通常富含不饱和脂肪,但棕榈油和椰子油等热带油例外。 Dr. Sarah Berry 详细解释了不同类型的脂肪,包括单不饱和脂肪、多不饱和脂肪和饱和脂肪,并解释了它们在食物中的来源以及对健康的影响。她强调了食物基质的概念,指出食物的结构会影响营养物质的影响,例如乳制品的结构可以调节其中饱和脂肪的影响。她还指出,高饱和脂肪摄入量通常是整体不健康饮食的标志,因为许多饱和脂肪来自超加工食品。她总结说,尽管存在一些例外情况(如发酵乳制品),但总的来说,人们应该努力减少饱和脂肪的摄入量,并建议人们应该关注食物本身,而非仅仅关注饱和脂肪含量。

Shownotes Transcript

If you're confused about the health effects of fats, you are not alone. You've probably read the headlines - fats are killing us! Then found claims they’re actually healthy in the same publication the following week.

Saturated fats have been touted as the worst of all. 

While there’s ambiguity around other fat sources, saturated fats are universally demonized.

But are they really the super villain we've been led to believe?  

Find out in this week’s episode.
