Investigating the microbial mechanisms contributing to host metabolism, with Dr. Amir Zarrinpar, MD PhD
This episode features Dr. Amir Zarrinpar, MD PhD, from UC San Diego (USA) speaking about his work on circadian biology and host metabolism, and what’s currently known about microbial mechanisms. Dr. Zarrinpar explains that in mouse models, restricting feeding to the nocturnal (awake) period is important for their metabolic and overall health. When mice eat… -
Interactions between immunity, gut microbiota, and metabolism, with Prof. Dirk Haller PhD
This episode features Prof. Dirk Haller from Technical University of Munich (Germany) speaking about his work in the field of nutritional immunology, trying to unravel how immunity and gut microbiota interact with metabolism, ultimately impacting the emergence of chronic diseases. He focuses on how microbe-host interactions in the gut impact inflammatory or tumorigenic responses –… -
Examining fermented foods for potential cardiometabolic health benefits, with Prof. Ben Willing PhD
This episode features Prof. Ben Willing PhD from the University of Alberta, Canada, speaking about his work investigating fermented foods such as kefir for potential cardiometabolic health benefits. The microorganisms associated with fermented foods are not standardized – for example, traditional kefirs have some microorganisms in common, but other microorganisms that are present sporadically. Moreover, kefir… -
Diet and gut microbiome contributions to host energy balance, with Dr. Karen Corbin PhD RD
This episode features Dr. Karen Corbin PhD RD from AdventHealth Translational Research Institute (USA), speaking about how the triad of diet, gut microbiome, and host characteristics contribute to energy balance as well as metabolic diseases. From the perspective of host physiology, she explores how to use diet to remodel the gut microbiome to impact energy… -
