Dr. Sarah Berry: 本期节目探讨了蜂蜜、枫糖浆、甜菊糖和龙舌兰等天然糖替代品是否比白糖更健康。虽然这些替代品通常被认为更健康、更天然,且加工程度更低,但事实并非如此简单。许多天然糖替代品也主要由果糖和葡萄糖组成,与白糖的代谢方式相似,对血糖的影响也类似。例如,蜂蜜和白糖都含有果糖和葡萄糖,其代谢方式相同,对健康的影响也相似。虽然一些天然糖替代品可能含有少量维生素、矿物质和多酚,但这些含量通常很低。此外,市售甜菊糖产品通常含有赤藓糖醇等其他成分,而研究表明赤藓糖醇可能与心血管疾病风险增加有关,但这方面仍需更多研究。龙舌兰糖浆主要由果糖组成,不会直接升高血糖,但过量摄入会使肝脏从果糖中产生脂肪。总的来说,各种天然甜味剂在所含糖分(果糖和葡萄糖)及其代谢方式方面非常相似。我们应该更关注隐藏在食物中的糖,而不是我们添加到食物中的糖。完整食物(如橙子)中的糖吸收速度较慢,不会导致血糖急剧下降,因为它们含有纤维,可以减缓糖的吸收速度。 Jonathan Wolf: 节目中探讨了食用糖后身体会发生什么,以及如何影响健康。食用糖后,糖进入肠道,进入血液,分解成果糖和葡萄糖。果糖直接输送到肝脏,而葡萄糖则在血液中循环。食用糖后血糖会迅速升高,然后下降,过量和反复的这种情况会对健康产生不利影响,可能导致炎症等不良反应。有些人会在摄入过多糖后血糖下降,这会导致饥饿感、注意力下降和能量消耗增加。
