Protect BIFIDOBACTERIA First

from Autism Parenting Secrets · host Len Arcuri, Dr. Sabine Hazan

Welcome to Episode 319 of Autism Parenting Secrets. For years, parents have heard about probiotics, gut health, dysbiosis, and the microbiome. But those broad concepts don't always answer the most important question: What should we focus on first? Dr. Sabine Hazan has spent more than two decades studying the microbiome, and her research has taken an unexpected turn. What began as an investigation into COVID immunity led her to a much larger discovery. Across autism, Alzheimer's disease, Parkinson's disease, cancer, Lyme disease, long COVID, inflammatory bowel disease, and many other chronic illnesses, one common thread kept appearing: declining levels of BIFIDOBACTERIA. In this conversation, Dr. Hazan explains why she believes this group of beneficial microbes deserves far more attention, why simply taking probiotics may not be enough, and why protecting the microbiome may be one of the most important investments families can make in their children's long-term health. Whether or not future research confirms every aspect of her current thinking, this episode offers a fascinating look into how one physician-scientist is approaching one of the biggest unanswered questions in autism. The secret this week is… Protect BIFIDOBACTERIA First You'll Discover: Why autism became "all about BIFIDOBACTERIA" for Dr. Hazan (3:15) The surprising difference between restoring and simply adding probiotics (24:05) Why protecting the microbiome may be even more important than rebuilding it (29:15) Several everyday factors Dr. Hazan believes can rapidly deplete BIFIDOBACTERIA (35:45) Why the future of autism may begin with measuring the microbiome much earlier in life (1:07:50) About Our Guest: Dr. Sabine Hazan is one of today's most highly regarded gastroenterologists and researchers helping shape the field of microbiome science. She is the CEO of Ventura Clinical Trials and founder of ProgenaBiome, a CLIA-certified, CAP-accredited laboratory exploring the relationship between the microbiome and conditions including autism, cancer, Parkinson's disease, Alzheimer's disease, and longevity. Dr. Hazan has led more than 46 clinical trials and has published extensively on stool testing, probiotics, fecal microbiota transplantation, and the role of the gut microbiome in chronic disease. She also founded the Microbiome Research Foundation to advance independent microbiome research. https://sabinehazanmd.com/ References in this Episode: ProgenaBiome Microbiome Research Foundation Let's Talk Shit by Dr. Sabine Hazan Autism Health Summit Documenting Hope Additional Resources: To learn more about personalized 1:1 support go to www.elevatehowyounavigate.com If you enjoyed this episode, share it with your friends.

Dr. Sabine Hazan believes one of the microbiome's most important signals has been overlooked.
