Jonathan Wall: 本期节目探讨了禁食对肠道健康的影响，特别是肠道菌群的变化。过去，由于食物获取的困难和食物保存技术的限制，人类定期禁食。而现代便捷的食物获取方式导致人们随时随地进食，这可能对身体和肠道微生物产生负面影响。 Tim Spector: 禁食会改变肠道菌群的构成，一些依赖食物的细菌会减少，而一些利用代谢废物的细菌会增加。进食会引发大脑向肠道发出信号，动员特定类型的微生物来处理食物中的不同成分。例如，Acomancia munisfilia 这种细菌以肠道粘膜为食，在禁食期间会大量繁殖，帮助清理肠道粘膜，促进肠道细胞再生。肠道细菌分解肠道粘膜是一种自然现象，类似于人体定期更新皮肤和指甲，有助于保持肠道健康和免疫系统强壮。我们需要给肠道中的“夜间微生物”提供一个合适的环境来发挥作用，这需要通过禁食来实现。目前尚不清楚最适合大多数人的禁食时间间隔，需要进一步研究来确定最佳的禁食方案，以及不同个体对不同禁食方案的反应。肠道中存在两种类型的细菌：一种在进食时活跃，另一种在禁食时活跃，两者共同维持肠道健康。间歇性禁食可能带来一些益处，例如增加能量、改善情绪和减轻体重。 Jonathan Wall: 节目的主要内容是介绍一项名为“The Big IF Study”的大型临床研究，该研究旨在探索间歇性禁食对情绪、能量和饥饿感的影响。研究人员希望通过这项研究了解间歇性禁食是否真的能够改善人们的感受，并找到适合每个人的个性化禁食方案。

Nowadays, food can be delivered to your door with just a few swipes of your smartphone. The result? Many of us eat more frequently, at any time of the day. And this may have some downsides. New research shows that for our gut bacteria to perform their helpful activities, we may have to embrace the dietary patterns of our ancestors. 

In today’s daily episode of ZOE Science & Nutrition, Jonathan is joined by Tim Spector to answer the question: How do gut bacteria repair your gut while fasting?

This episode is part of a limited series to celebrate the launch of The Big IF study: The world’s biggest clinical study to discover how intermittent fasting affects our mood, energy and hunger.  Want to know if intermittent fasting can work for you?
