Tucker Goodrich: Debugging Life

Introduction

Nick asked me to do a YouTube livestream to go over some research he had been doing. He drilled down on a reference in a high-profile cardiology guideline article and discovered that the authors had inverted the research finding in the referenced paper to claim the inverse of what it actually showed.

We discussed this, and then I gave some more context about the matter and one of the authors.

Introduction

It's well-known that lipid peroxidation is involved in aging and longevity. But what can we do about it? Dr. Shchepinov has been researching using deuterium to 'shore up' the PUFAs like those in seed oils to prevent them become toxic metabolites. He's had some interesting successes, and we discuss at length his new book: "Breaking the Chains of Aging".

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 give some background to that one, and his future research plans in light of that paper, we have an enlightening discussion on the potential role of deuterium in obesity and chronic disease.

Biography:

"John Roger Speakman (born 1958) FRS FRSE FRSB FRSA FMedSci FRSS is a British biologist working at the University of Aberdeen, Institute of Biological and Environmental Sciences, for which he was Director from 2007 to 2011. He leads the University's Energetics Research Group, which is one of the world's leading groups using doubly labeled water (DLW) to investigate energy expenditure and balance in animals. Between 2011-2020, he was a '1000 talents' Professor at the Institute of Genetics and Developmental Biology, Chinese Academy of Sciences, in Beijing, China, where he ran the molecular energetics group. In 2020 he moved to the Shenzhen Institutes of Advanced Technology, Chinese Academy of Sciences in Shenzhen, China where he works at the Center for Energy Metabolism and Reproduction and Head of the Shenzhen Key laboratory of Metabolic Health."

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: https://www.youtube.com/live/JDsbpAJ28U4?si=4n7mSt56JiQDXTGN _______________________________________

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.

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.

This is the only human study I'm aware of showing harm from eating marine foods. The Japanese and the Eskimos do not suffer from infertility, so I think this gentleman must have been doing something wrong.

"I lived for 100 days on nothing but marine animal food (seal, fish, crustaceans and molluscs) and water; weights of all food were recorded…."

Jacob's Discussion Notes

Topics to cover

1. Omega-3 paper –
   1. Overall, our results revealed that 68% (23/34) of flavored and 13% (5/38) unflavored consumer Ω3 supplements exceeded the TOTOX upper limit set by the Global Organization for EPA and DHA (GOED) voluntary monograph standard of ≤ 26, with 65% (22/34) flavored supplements and 32% (12/38) unflavored supplements failing the PV upper limit of ≤ 5 and 62% (21/34) flavored supplements exceeding the p-AV upper limit of ≤ 20.
      1. What's important is that peroxide was still significantly different in those with added versus non added extracts (0.04) almost double the PV
   2. How does fish oil metabolize?
      1. Peroxides, then aldehydes (Ω-3HHE & Ω-6 HNE, etc.)
      2. Why do I think it probably doesn't matter?
         1. 2 big studies – in the first study, after seven weeks of supplementation with 8 grams of oil per day, the authors found no signs of oxidative stress in any of the groups after looking at nine different measures (4-HHE, 4-HNE, 8-iso-prostaglandin F2α, alpha-tocopherol, total glutathione, glutathione reductase, glutathione peroxidase, catalase, and C-Reactive Protein) of oxidative stress in the blood and urine 4. This study demonstrated that high dosages of highly oxidized fish oil do not induce oxidative stress in our bodies."
         2. "The second study was conducted by the same group and used the same study design, but looked at four additional markers of oxidative stress related to vascular inflammation (intercellular adhesion molecule 2 (sICAM-2), soluble vascular adhesion molecule 1 (sVCAM-1), interleukin 6 (IL-6) and oxidized LDL cholesterol) 5. Again, no impact on these markers was found with consumption of abnormally oxidized fish oil." BUT
         3. point to consider is that may have adverse effects on lipids

https://www.cambridge.org/core/journals/british-journal-of-nutrition/article/oxidised-fish-oil-does-not-influence-established-markers-of-oxidative-stress-in-healthy-human-subjects-a-randomised-controlled-trial/32EB4869D3012F6E44FD23A7D25D7F7E

Would want to point out that ICAM and VCAM does

1. How should I think more generally about oxidized oils?
   1. First of all, let's go over fats and how that works – note that we don't have 15 desaturase which would convert 06 to 03 – what's going to be the broad point? Each 06 and 03 come with anti-inflammatory elements, one is just less inflamm
      1. Notice that AA derived eicosanoids products such as lipoxins actually follow https://www.ncbi.nlm.nih.gov/pmc/articles/PMC164223/

1. Something sympathetic for you – Nicolantino et al. argue 06 is a driver because oxidation products of LA are high in atheromas https://openheart.bmj.com/content/5/2/e000898 – why is this not replicated in most of the systematic analysis?
   1. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8924827/#:~:text=Indeed%2C%20an%20inverse%20relationship%20between,CHD)%20risk%20%5B9%5D. (granted this FBG and other markers of coronary disease increase etc)
   2. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6029721/ (more linolenic = less diabetes)
   3. https://www.bmj.com/content/366/bmj.l4697
   4. https://www.tandfonline.com/doi/abs/10.1080/10408398.2022.2056867 (linear LA = less CHD)
   5. More LA less CVD https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4334131/
   6. LA inverse AA positively associated with diabetes https://www.sciencedirect.com/science/article/abs/pii/S026156142030008X
   7. Cochrane style review unclear https://pubmed.ncbi.nlm.nih.gov/24723079/
   8. Cancer risk? Minimal except maybe prostate cancer https://www.nature.com/articles/s41416-020-0761-6
2. More to the point, there is no evidence that even giving straight ARA still unclear up to 1 gram https://www.cambridge.org/core/journals/british-journal-of-nutrition/article/systematic-review-of-the-effects-of-increasing-arachidonic-acid-intake-on-pufa-status-metabolism-and-healthrelated-outcomes-in-humans/6A0167CBF8EC148B4855C25D002E4AC4
   1. Even if metabolized, the oxidative derivatives can do cool things
   1. would other oils increase oxidative stress? Maybe https://iopscience.iop.org/article/10.1088/1755-1315/217/1/012055

(source) https://lpi.oregonstate.edu/mic/other-nutrients/essential-fatty-acids

1. Is the body made to deal with oxidative stress?
   1. What is the evidence that the mouse model is valid? Note Scandinavian SNPs associated with rancid consumption
   2. Changes in MDA are unpredictable and highly oxidized meals can generate low MDA etc not easy to say that
   3. Omega 3 attenuates effects of oxidation and increases parameters of oxidative stability https://pubmed.ncbi.nlm.nih.gov/31563611/
1. Chocolate
   1. Cadmium is toxic lol but here it data on recruiting pro-inflammatory macrophages in artery https://pubmed.ncbi.nlm.nih.gov/27156912/
   2. Lead also bad for various reasons
   3. Lets go over levels, why prop 65 exists versus what an IRL is and 2.2 8.8 mcg/day means in any context

If you have any questions about sources for things discussed please ask in the comments.

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?

Introduction

We're honored to be joined today by Autumn Smith of Paleovalley and John Etchart of Wild Pastures. These related companies (John is Autumn's brother-in-law) work to deliver healthy, regeneratively-farmed foods to their customers.

"At Paleovalley, our mission is to help people reclaim vibrant health. We provide products that prioritize nutrient density in an industry that prioritizes everything else. We believe that every dietary choice and every added ingredient is a powerful opportunity to love and care for oneself."

https://paleovalley.com/about

Wild Pastures:

"Turning The Page To A Healthier You & A Healthier Planet

"We provide healthy, rotationally grazed, pasture-raised meats without hormones or antibiotics. Rotational grazing helps restore soil and sequester carbon from the atmosphere. We use no chemicals on our pastures... ever.

"We only work with small family farmers located in the USA using regenerative farming practices.

https://wildpastures.com/

As I mention in the episode, Autumn sent me a sample box of the various products they offer, include meat from Wild Pastures and beef sticks and other products from Paleovalley.

Biography:

"Autumn Smith suffered from debilitating digestive issues and crippling anxiety for most of

her life. Specialist after specialist told her nothing could be done, and she was ready to give up.

But as one final attempt at a life free of health issues, Autumn decided to harness the power of

whole foods. She cleaned up her diet and in just 30 days, her IBS was cured. But that was just

the beginning. She also had less anxiety, was mentally sharper, and a bubbly side of her that she

forgot existed came back. Since then, Autumn has dedicated her life to helping others harness

the power of whole foods to live vibrant lives.

"In 2013, she and her husband Chas launched Paleovalley, a company dedicated to helping

people get the essential nutrients they need, without added sugars, grains, and other harmful

ingredients. But they didn't stop there. After learning about the healing powers of grass fed,

pasture raised meat - both for our bodies and the planet - Autumn and Chas started their next

venture. In 2018, they launched Wild Pastures, a regenerative meat delivery service that sends

100% grass fed pasture raised meat directly to your doorstep."
