Gut Questions? Gut Questions?
-
- Health & Fitness
Conversational interviews about the gut microbiome between good friends who also work together running DePaolo Lab and CMiST, Center for Microbiome Sciences & Therapeutics, at the University of Washington in Seattle, WA.
One friend, Will, is a scientist and knows a sh*t ton about the gut microbiome. The other friend, Parker, is communications specialist for CMiST (aka a Jill-of-all-trades and right-hand man to Will). Join Parker, as she interviews her friend (since 1995) and boss (since 2015), Dr. Will DePaolo, about gut microbiome research, gut health, and nutrition.

S1 E6: Brief wrap of season 1 and season 2 preview
In the second season of Gut Questions? Will and I get into the research and business of -biotics. Will is going to cover probiotics, prebioitics, synbiotics, and postbiotics. He'll give a brief overview of each and then we'll talk about how each is being researched and presented in the news and social media. What comes across all of the news outlets, online or in print, and in our social media feeds can be pretty confusing and even misleading so, I thought I could get Will's expert take on what I find out there in the wilds of the internet.
If you've gut a question(s) you would like Will to answer in an upcoming episode, email me, Parker, at aparker@medicine.washington.edu or submit a questions on the podcast website, www.yourgutquestions.com/contact

S1 E5, PUFAs and infection, Part 4: Relevance to human health
Episode 5, part 4 – Will talks about why the results from this study are relevant to our everyday lives.
DePaolo Lab ultimately found that the presence of omega-6 polysaturated fatty acids (arachidonic acid was used in this project) worsens inflammation when challenged with virus or bacteria. So, a diet high in omega-6 fatty acids can weaken the immune response to a viral or bacterial infection. Will and I also get into a little discussion about immunity as well as what the lab found when looking at omega-3 fatty acids using the same assays that were used to study omega-6 fatty acids.

S1 E5, PUFAs and infection, Part 3: Details of omega-6 fatty acid (arachidonic acid)
In the this part of the PUFA episode, Will explains the growth and virulence changes of Yersinia enterocolitica under room and body temperatures. In essence, omega-6 fatty acids (arachidonic acid was used in this project) change the pathogenesis of the yersinia creating a more virulent bug. Again, the the lab wanted to determine if infection rate or severity is increased when omega-6 fatty acids are in the system at room and body temperatures. So, pay attention to the temperature talk at the beginning of this part because it is key to this project. It's pretty fascinating.
Important numbers:
• 68-77 - room temperature (celsius), the temperature at which Yersinia enterocolitica typically grows
• 37 - body temperature (celsius), which Yersinia enterocolitica can survive in with the presence of omega-6 fatty acid (arachidonic acid)
To check out a figure showing virulence factor expression of Yersinia enterocolitica at room and body temperature (paper is posted as well for anyone who really wants to deep dive into Y. enterocolitica) visit our Gut Questions? podcast website and go to “Show Notes" → https://www.yourgutquestions.com/shownotes

S1 E5, PUFAs and infection, Part 2: The project design
Episode 5, part 2 - Will sets up the infection project (which was very enlightening for me).
In part two of the PUFA episode, Will gives some fascinating detail on the bacteria of choice for this study, yersinia enterocolitica, and how exactly it goes about causing foodborne illness in humans. Essentially, the bacteria paralyzes the immune system by injecting immune cells with a "needle" (here we go with needles again) and depositing virulence factors. So, the question the lab wanted to answer was how omega-6 fatty acids, which are consumed in excess in the US, might affect a gut-borne diarrhea causing pathogen.
Important numbers:
2011 yearly foodborne illness estimates for the US (Center for Disease Control)
• 48 million – people affected
• 128,000 – people hospitalized
• 3,000 – people die
2010 yearly foodborne illness estimates (World Health Organization)
• 600 million – people affected
• 420,000 – people die
• 30% – of the 420,000 are children
If you want to read more about foodborne illness and food safety or be reminded of the greatness of Stefon (SNL), check out the show notes on the Gut Questions? podcast website under “Show Notes" → www.yourgutquestions.com/show-notes.

S1 E5, PUFAs and infection, Part 1: Omega-6 and Omega-3 fatty acids
Episode 5, part 1 - Will lays the groundwork for talking about the PUFAs and infection project.
In the first part of this episode, Will introduces the two types of polyunsaturated fatty acids (PUFAs) - omega-6 and omega-3. Both types are essential to our diets but, the ratio in which they are consumed is critical. Will talks about why the ratio of these fats is important and how gut bacteria are invovled.
Important numbers:
• 1:1 or 1:3 - a healthy ratio of omega-6 to omega-3 fatty acids
• 1:20 - a very unhealthy ratio of omega-6 to omega-3 fatty acids that is seen amongst a large population here in the US
If you would like to read more about PUFAs or want to be reminded of the greatness of Stefon on SNL, I have posted those on the Gut Questions? podcast website under “Show Notes" → www.yourgutquestions.com/show-notes

S1 E4, Part 2: Nonalcoholic fatty liver disease (NAFLD) - discussion
In the second part of this episode, Will and I talk about a bunch of stuff:
• How nonalcoholic fatty liver disease (NAFLD) is reported on / presented in the news and social media
• Why there is such a “paucity of studies” looking at the relationship between diets, the microbiome, and disease
• The gut-brain connection
• Bacteria don blue or red jackets as they do their best to adapt to their changing environment
This episode is actually a peek into how our conversations go in general, that is, in and out of the lab: I ask a ton of questions, often seemingly random, and Will answers them, and always understands where I’m going with my seemingly random questions.
If you would like to learn more about the gut-brain connection or are just curious about the Pizza Bagel jingle I reference, I have provided some resources in our show notes. Check them out at the Gut Questions? podcast website under “Show Notes" → www.yourgutquestions.com/show-notes
If you would like to learn more about this project, the subsequent publication from this project is posted on the Gut Questions? podcast website under “Show Notes" → www.yourgutquestions.com/show-notes
