Chris Kresser & Dr. Joel Kahn

Date: 2018-09-27 | Duration: 3h 51m

Episode Overview

Chris Kresser and Dr. Joel Kahn engage in a detailed discussion about nutrition, cardiovascular health, and the complexities of dietary science. They critically examine the limitations of nutritional epidemiology, emphasizing how observational studies often fail to account for confounding factors like lifestyle and diet quality. Both guests highlight the challenges in interpreting data on saturated fat, cholesterol, and red meat consumption, noting that randomized controlled trials frequently contradict popular media narratives. They stress the importance of looking beyond headlines to understand the nuanced relationship between diet and chronic diseases such as heart disease and cancer. The conversation also delves into the role of plant-based versus animal-based diets, with both experts acknowledging the benefits of whole-food, plant-rich eating patterns while recognizing that individual needs vary. They discuss mechanisms like TMAO and its controversial link to cardiovascular risk, as well as the significance of nutrient bioavailability, particularly vitamin B12 in vegan diets. Personal anecdotes and clinical experiences underscore their points, including references to longevity in populations like those in Okinawa and Loma Linda. Ultimately, Kresser and Kahn advocate for a balanced, evidence-based approach to nutrition that prioritizes quality foods, individualized care, and ongoing scientific inquiry.

Starting point is 00:00:54 Came back to Michigan, very active cath lab heart attack. Starting point is 00:01:19 in Detroit, one in Austin, Texas. Starting point is 00:01:33 What better purpose in life? Starting point is 00:01:53 Five books and a bunch of medical papers and a whole lot of blogs. Starting point is 00:02:26 And, you know, conventional medicine didn't have much to offer for me. Starting point is 00:03:18 it's vegan, but it's, you know, it's heavily influenced by Japanese tradition and cuisine, Starting point is 00:03:52 that point too. Starting point is 00:04:31 that I had about vegetarianism and veganism. Starting point is 00:05:08 when it comes to diet. Starting point is 00:05:38 without thinking about the entire patient. It's pretty unusual. And we're going to represent a Starting point is 00:06:04 I mean, this is pretty rare segment. Starting point is 00:06:21 The biggest problem with nutritional research epidemiology is that it Starting point is 00:07:11 of the diet. Starting point is 00:07:41 They're not considering the quality of the diet. Starting point is 00:08:22 Are we talking about avocados and healthy whole foods? Starting point is 00:08:51 not the whole solution a lot of scientists i'll give a shout out to los angeles brightest nutrition Starting point is 00:09:17 You see something in a cell. Starting point is 00:09:40 That is something you honor, but it's a long jump from there to human. Starting point is 00:10:08 Do we have the data to ask the question, does protein correlate with survival? Starting point is 00:10:26 Do they lift weights? Starting point is 00:10:45 I mean, there's never been a randomized clinical trial of smoking because that would be unethical. Starting point is 00:11:13 And there's even more than that. Starting point is 00:11:45 to make reasonable conclusions. Starting point is 00...
