Summary

In this episode, Dr. Jessica Steier and Dr. Sarah Scheinman welcome Dr. Kristen Panthagani to explore the complex world of the human microbiome. The scientists discuss the fundamental concepts of gut health, examining the roles of beneficial and harmful bacteria, as well as the effects of probiotics, prebiotics, and antibiotics. They investigate the emerging research on the gut-brain connection and its implications for mental health, while addressing the effectiveness of various interventions including dietary changes and supplements. Throughout the conversation, they emphasize the importance of evidence-based approaches to microbiome health and discuss future directions in this rapidly evolving field of research.

0:00.0	You're listening to an Airwave Media podcast.
0:28.2	Welcome to Unbiased Science, where we bring scientific method to the madness.
0:32.9	We're your hosts, Dr. Jess Steyer, and Dr. Sarah Scheidman.
0:37.5	And we are having all of the tech issues in 2025.
0:41.1	Last week, it was Sarah's laptop giving us trouble.
0:42.3	This week it's mine.
0:46.3	So I am on my phone, in my phone right now.
0:50.7	If you're watching on video, I'm really like you're getting an up nostril shot. So I apologize.
0:52.0	But the show must go on. And this week, we are joined once again
0:57.3	by the amazing Dr. Kristen Pantagani to talk all about the microbiome, because y'all have
1:04.3	questions about the microbiome, and we are joined by not one, but two people who have expertise on this topic.
1:12.6	So I'm going to be doing a lot of listening and learning.
1:16.7	But just to kick things off, Kristen, you're what I refer to as a mud fun.
1:21.4	You have both an MD at a PhD.
1:24.2	Can you just remind listeners what your credentials are? So I did my MD and my PhD at Baylor
1:32.0	College of Medicine. I do not speak for the institution. I should throw that out there. I speak for
1:37.6	myself. But my PhD was in studying the human microbiome. Technically it was in genetics, but my focus of
1:43.7	my thesis was metagenomics in studying the human microbiome. Technically, it was in genetics, but my focus of my thesis was metagenomics
1:45.3	and studying the human microbiome. And then since that time, in particular, when the pandemic started,
1:51.8	which was my last year of grad school, I've launched into the world of science communication and
1:57.6	health literacy. And I'm now an emergency medicine resident at Yale. Also don't
2:03.2	speak for that institution. I have to put all the disclaimerers in there. And I now focus more on
