The Secret to Reversing Gut Aging – Explained By An Expert

from Well Beyond 40

FULL EPISODE: https://youtu.be/iG9M8DPyoOw?si=IDhlyMYrq4ECsszN  Dr. Kiran Sachdev speaks the language of the gut, including the less glamorous details most people avoid discussing. Her approach helps patients improve digestion, rebuild their microbiomes, and understand how gut health can influence everything from brain fog to bone health. In this episode, she uncovers how aging can change your stomach acid, digestion, motility, and microbiome. We explore why eating more protein is not enough if you cannot properly break it down, and why pairing protein with fiber and polyphenols can help you receive more of its benefits. You’ll also learn how to recognize signs of an aging gut, rebuild beneficial bacteria, approach fiber gradually, and protect your long-term health. (00:00) How low stomach acid can lead to indigestion and why proton pump inhibitors may be worsening your digestive health. (01:20) Why menopausal women need increased protein and how poor stomach acid prevents proper protein breakdown. (01:51) The key differences between proteolytic and saccharolytic fermentation and why fiber prevents protein-induced brain fog. (02:57) How to perform a simple at-home baking soda test to determine if you need stomach acid supplementation. (04:29) Why gut motility slows down with age and how bacterial imbalances create symptoms often misdiagnosed as IBS. (05:22) The step-by-step process for reinforcing your gut barrier and rebalancing your microbiome in just a few months. (07:42) How to use polyphenols like extra virgin olive oil and pomegranate extract when fiber causes digestive distress. (09:55) What triggers SIBO as you age and why a strict carnivore diet starves essential gut microbes over time. Full show notes (including all links mentioned): https://jjvirgin.com/drkiran
