In this episode of The Fit Physician Podcast, Jake and Dr. Suzanne Rutherford dive deep into the benefits of dietary fiber, exploring its role in reducing the risk of all-cause, cardiovascular, and cancer mortality. Building on the success of the first Science Snack about estrogen replacement therapy, this second edition looks at a systematic review and meta-analysis published in 2023 that compiles data from 32 studies involving over 2.5 million participants globally.

Dr. Rutherford discusses the immense benefits of increasing fiber intake and explains how fiber might just be the strongest lever you can pull for longevity and disease prevention. She breaks down the types of studies included in the analysis, defines key terms like relative risk reduction, and emphasizes that even small increases in fiber intake can yield significant health benefits.
