Richard Johnson: 我是糖代谢领域的专家,我的研究表明果糖是导致肥胖和代谢疾病的主要原因。虽然水果和蜂蜜中含有果糖,但我们日常摄入的大部分果糖来自添加糖,如白糖和高果糖玉米糖浆。天然水果中的其他营养成分可以抵消果糖的负面影响,但果汁和一些富含果糖的水果(如枣和无花果)应避免食用。果糖通过抑制ATP的产生和阻止脂肪分解来促进肥胖,尿酸在其中起关键作用。人体可以将葡萄糖转化为果糖,而富含淀粉的食物会增加葡萄糖水平,进而促进果糖的产生。高血糖会引起胰岛素抵抗,导致胰岛素水平持续升高。含高果糖玉米糖浆的饮料对健康危害极大。低碳水化合物饮食有助于减少果糖的摄入和体内生成。盐和尿酸会刺激葡萄糖转化为果糖的途径,但在低碳水化合物饮食下,它们的影响会减弱。果糖会升高血压,而低糖饮食有助于降低血压。一些代糖会转化为果糖,应避免使用;而另一些代糖,如甜叶菊和三氯蔗糖,则相对安全。阿洛酮糖是一种有益的低卡路里天然糖,它不会降低ATP水平,可能具有降低血糖和刺激GLP-1分泌的益处,并且不会像果糖那样对尿酸和一氧化氮产生负面影响。 Robert Lufkin: 通过与Richard Johnson博士的对话,我了解到果糖可能是导致代谢疾病的一个被低估的因素,它不仅存在于加工食品中,而且人体还可以将葡萄糖转化为果糖。为了避免果糖的危害,仅仅减少果糖摄入是不够的,还需要减少葡萄糖的摄入,低碳水化合物饮食是控制体内葡萄糖和果糖水平的有效方法。高盐饮食在高碳水化合物摄入的情况下会加剧果糖的产生,从而增加患高血压的风险。在选择代糖时,需要谨慎,因为有些代糖会转化为果糖,而另一些则相对安全。阿洛酮糖作为一种新型代糖,可能具有降低血糖、刺激GLP-1分泌和控制体重的益处,值得进一步研究。

Deep Dive

Chapters
This chapter explores the science behind fructose and its role in metabolic diseases. Dr. Johnson reveals why fructose is a concern, particularly in processed foods and fruit juices, and its impact on fat storage and energy levels.
  • Fructose is a sugar found in fruit, honey, table sugar, and high fructose corn syrup.
  • Fructose is a major contributor to metabolic disease.
  • Fruits contain substances that counteract fructose's negative effects, but fruit juices concentrate fructose and are less beneficial.

Shownotes Transcript

This week we get to unlock the secret to better health with Dr. Richard Johnson, a leading mind in the field of sugar metabolism, as he reveals the hidden dangers of fructose and its surprising role in metabolic diseases. Dive into the science of sugars and uncover the biological mechanisms that make fructose a stealthy culprit for obesity. While fruits like dates and figs may seem harmless, their high fructose content is a concern, especially when consumed in juices. Dr. Johnson demystifies the connection between sugar and fat storage, and why the body mistakenly believes it's low on energy, leading to weight gain.Explore the fascinating interplay between fructose, salt, and carbohydrates, and learn how these elements influence blood pressure and metabolic health. Discover why a low-carb or keto diet might be your best defense against the adverse effects of salt and uric acid. We also navigate the world of sugar substitutes, with a spotlight on allulose, a promising alternative. We also discuss Dr. Johnson's informative book  "Nature Wants Us to Be Fat" for further reading on this critical healthcare topic.https://drrichardjohnson.com/ (20% off using DrLufkin20): https://rxsugar.com/discount/DrLufkin20)
