Ep. 23: Ep. 23: "Ep 23 Doctors Should Tell Patients that High Linoleic Acid Seed Oils are Unhealthy"—with Raphael Sirtoli and Dave Feldman

Tucker Goodrich: Debugging Life

Introduction So apparently there is some demand for discussion/debate on the topic of seed oils and health. Dave Feldman (Ep. 9) had considered doing this at his recent conference, but couldn’t fit in the time. He’s since regained interest in the idea, and reached out to Andreas Eenfeldt and Ted Naiman, who have expressed skepticism. They replied: “We decline as we feel this debate is a distraction. The reason is that we see no good scientific evidence for replacing any source of added pure fat with another. It's not the right question.” Since there’s so much interest, and clearly...

Tucker Goodrich: Debugging Life

Introduction I am honored to be joined by John Speakman, a leading authority on energy balance in animals, and in the use of the doubly-labeled water method of determining energy balance. This has led him into the study of obesity, among other topics, where he has become a recognized expert. Our discussion was prompted by his recent paper, “Total Daily Energy Expenditure Has Declined Over the Past Three Decades Due to Declining Basal Expenditure, Not Reduced Activity Expenditure”, which casts a new light onto the world pandemic of obesity. In addition to discussing a few of the papers that...

Tucker Goodrich: Debugging Life

Introduction Cancer is the second-leading killer of Americans, and is increasing both around the world and increasingly affecting younger and younger people. It’s obviously important to understand what environmental factors might affect our susceptibility to the various cancers. Here we discuss what I think is a key paper showing a link between our environment, genetic mutation, and metabolic dysfunction in cancer cells. “The Major Lipid Peroxidation Product, Trans- 4-Hydroxy-2-Nonenal, Preferentially Forms DNA Adducts at Codon 249 of Human P53 Gene, a Unique Mutational Hotspot in...

Tucker Goodrich: Debugging Life

Introduction What about fish oil? Is it a problem due to oxidation and contamination? Is it beneficial to health as many claim or is it a PUFA that’s bad for your health? Jacob recently published an analysis of various fish oils with the team at Consumer Labs, looking at oxidative toxicity and purity of a wide variety of commercially available fish oils. We discuss omega-3 and health, fish oils and oxidation, the science of seed oils and health, and, as a bonus, the problem with chocolates. This is definitely a bit of a geek fest, so let me know if you have any questions. Guest info Jacob...

Ep. 18: What Causes Insulin Resistance?—with Matt Quinn and Dr. Brian Kerley show art Ep. 18: What Causes Insulin Resistance?—with Matt Quinn and Dr. Brian Kerley

Tucker Goodrich: Debugging Life

Diabetes, broadly defined, afflicts greater than 50% of the U.S. population. The hallmark of type 2 diabetes is insulin resistance. While many are unable to answer the question of why a formerly rare disease now afflicts the majority of the population, we go over research dating back to 1964 that makes it clear that we have a pretty good idea of what causes insulin resistance. Scientists can easily induce insulin resistance in humans. How do they do it, and what might it tell us about what has caused our epidemic of diabetes?   Guest info Matt Quinn   Biography: TL;DR Here's what I...

Tucker Goodrich: Debugging Life

Introduction We look at a paper about the process of how the fats in seed oils become toxic, and what effects those toxins can have. This paper is a broad overview of the related disease processes, which we will discuss to further understand how one thing can be driving many different disease processes. “The study of lipid peroxidation (LPO) processes has become a rapidly growing field in medicine and biology, based on increasing evidence that LPO is involved in the development of many chronic diseases, e.g. [references removed] (1)    Asthma (2)   ...

Introduction We are honorored to be joined by Prof. A. J. Hulbert, noted zoologist and author of Omega Balance: Nutritional Power for a Happier, Healthier Life. “In Omega Balance, noted scientist Anthony J. Hulbert explains how the balance between [Omega-3 and omega-6 fatty acids] in the human food chain has changed over the last half-century and the very serious negative health impacts this imbalance has created. An imbalance of these omega fats contributes to increased rates of obesity, diabetes, cardiovascular diseases, allergies, asthma, as well as cancer and a variety of other...

Tucker Goodrich: Debugging Life

Introduction We look at a paper enlightening what causes chronic disease, in the context of a huge population of people who suffer from the most common human mutation, to the aldehyde dehydrogenase enzyme that detoxifies both alcohol and seed oil metabolites, the ALDH2*2 mutation. We discuss how this mutation is thought to affect the people who have it through the lens of the paper at hand. This was a difficult video for me to edit, as both Matt and Brian share their experiences with the topic we are discussing in their own families. I thought this was excellent, and hope many others can learn...

Introduction
So apparently there is some demand for discussion/debate on the topic of seed oils and health. Dave Feldman (Ep. 9) had considered doing this at his recent conference, but couldn’t fit in the time.
He’s since regained interest in the idea, and reached out to Andreas Eenfeldt and Ted Naiman, who have expressed skepticism. They replied:
“We decline as we feel this debate is a distraction. The reason is that we see no good scientific evidence for replacing any source of added pure fat with another. It's not the right question.”
Since there’s so much interest, and clearly that opinion is not defensible—probably why they avoided the debate!—Raphael Sirtoli volunteered to take the con side of a debate, topic:
“Doctors Should Tell Patients that High Linoleic Acid Seed Oils are Unhealthy”
This was a debate proposition that Raphi had suggested recently, and it had also been declined. (More about that in a future episode.)
So, here we are. Please enjoy, and as always, post questions or comments in the comments below.
The debate on Dave’s YouTube channel is here:
