Sigma nutrition radio has been a staple for evidence-based nutrition podcasting for the better part of a decade. But truly, even among other similar podcasts, it’s in a league of its own. The guest list is essentially the who’s who of nutrition academia, with interviews digging into the nuance of research coming directly from the sources, covering an incredibly broad span of nutrition topics. Danny Lennon started this endeavor on his own, but in more recent years, it’s expanded to include Dr. Alan Flanagan and Dr. Niamh Aspell. As Alan, Danny and Eric were recently at a conference together, Iron Culture took the opportunity to sit down with them and learn about what they’ve learned as one of the longest-running science-based nutrition podcasts.
