2) Stephan Guyenet, PhD
Stephan is an obesity researcher, neurobiologist, and author. In addition to his research, he enjoys synthesizing and communicating science for a general audience over at his hugely successful blog. Stephan has a BS. in biochemistry (University of Virginia) and a PhD in neurobiology (University of Washington). He recently published the fantastic book ‘The Hungry Brain’, which dives into the causes of obesity from the perspective of overeating and related brain chemistry.
3) Chris Masterjohn, PhD
Chris has a PhD in Nutritional Sciences from the University of Connecticut. He was formerly an Assistant Professor of Health and Nutrition Sciences at Brooklyn College. Chris currently writes detailed nutritional science articles on his blog chrismasterjohnphd.com and hosts a podcast, Mastering Nutrition.
4) Brad Dieter, PhD
Brad holds a PhD. in exercise physiology from the University of Idaho. Brad has also done research training as a fellow in biomedical research, examining how nutrition and metabolism influence disease. Brad also runs Science Driven Nutrition, an online platform that aims to spread evidence-based nutrition information.
In This Episode We Discuss:
Differences between different SFA’s (butyric vs. lauric vs. myristic, etc.)
Benefits of consumption of SFA-containing foods?
Effects at cellular level: ease of storage, oxidation proneness of different fatty acid types, role in cell membrane
Effect of SFA on LDL-C & LDL-P (and hence CHD risk)
Effect of SFA on blood lipids
Effect of SFA (and/or total dietary fat) on food intake: effect on satiety? palatability?
Reducing SFA: If lowering SFA intake, how much does the replacing nutrient make (MUFA vs. PUFA vs. CHO vs. PRO)
Food sources/Delivery method: Isolated SFA intake (e.g. spoonfuls of coconut oil) vs. SFA packaged alongside other nutrients/fibre and phytonutrients (e.g. some oil drizzled on a salad)
Practical Implications: Is there a best target intake range of SFA for health?
Is there an “optimal” ratio of SFA:MUFA:PUFA?
Are current nutritional guidelines for SFA intake suitable? (The American Heart Association recommends aiming for a dietary pattern that achieves 5% to 6% of calories from saturated fat.)

| 0:00.0 | You know, we're all on the same page when it comes to what the research says, you know, what the interpretations are and what role it really plays in overall health, specifically towards disease statuses like cardiovascular disease. |
| 0:20.0 | As a community of scientists and researchers, you know, we don't have all of the answers, but |
| 0:25.4 | we do have a pretty good understanding of how nutrients like saturated fat really do impact |
| 0:31.2 | our overall health. |
| 0:32.2 | And so I think nutrition isn't quite the black box. |
| 0:35.5 | A lot of people think it is, and there is a substantial amount of research |
| 0:39.1 | that can tell us what we do know and what we don't know. |
| 0:41.3 | And I think, you know, as a community, |
| 0:43.3 | we've done a pretty good job of trying to pin those things down. Hello and welcome to Sigma Nutrition Radio. |
| 1:05.6 | As always, I'm your host, Danny Lennon, and today is somewhat of a milestone episode, a very special one for the podcast |
| 1:14.3 | and for me personally that we've reached episode 200. So whilst quite an arbitrary number is a |
| 1:21.6 | nice milestone to tick off to say that we've made it this fire, which is in large part |
| 1:26.4 | due to your support if you've |
| 1:28.4 | listened to this show at all over the past number of years, especially if you are a regular |
| 1:33.0 | listener and listen into every episode. If so, I want to say a massive thank you first and foremost |
| 1:38.9 | before we get into the episode because without you, the show wouldn't be where it is and we can |
| 1:43.5 | continue to do this |
| 1:44.7 | and continue to talk to the level of guests that we can on the podcast and get their insights. |
| 1:50.3 | So thank you so much for that. |
| 1:52.3 | And if any of you do continue to share the show on social media, I see a lot of you posting it |
| 1:57.5 | on Facebook or putting it into different Facebook groups or putting |
| 2:01.1 | it on Instagram and tagging your friends. |
