Seed Oils (Linoleic Acid) and Susceptibility to Burning

This is one of my favorite twitter threads, but twitter is a strange, fluid place, so I thought I would memorialize it here for posterity.

I present the thread first as a narrative; the links to the tweets will appear below, along with the author's information.
Ok, time for a MIND. BLOWN. thread

I was cooking myself lunch just now. I wanted something quick and practical (and meat is always on the menu) so I went for steak and butter on steel pan. About a pound of it.

I'm not a frequent cook so sometimes I mess things up a little.

I was putting away things in the fridge when realized butter was smoking a lot.

I rushed to add the meat, butter splashed and half my thumb got licked by smoking butter (almost 200 C or 350 F)

I had read about @TuckerGoodrich's stories about resistance to sun burn and fire burns when you substitute PUFAs from your diet and my first reaction was confusion:

I very well know what an oil burn feels like and it just didn't hurt as much! Plus, my skin is not even red!

No pain, no redness, no swelling, NADA!

I had already noticed a huge, HUGE difference with my tolerance to sun but this is even crazier!


Of course other factors can't be excluded, such as placebo effect 

It's going to take a very, very good reason for me to ever use industrial PUFA oils in my kitchen again.

Funny thing is it's a bit awkward to even talk to people about this. People will surely think I'm crazy (or a quack)....

I'm telling you guys, @TuckerGoodrich is right on to something huge with potencially deep implications for health in general.

Someone has to give this a shot in formal research.

Great stuff. Exciting times

All thanks to Twitter. I would never have known about this anywhere else in a hundred times.

Plus people who are willing to direct you towards links, references and awesome discussions.

Fire-resistance, by diet!

I'm really blown away! Say what you will, quack or not.

End of thread.

Please somehow try this (SAFELY) at home!

Podcast Interview: "A Cautionary, Fascinating Tale of How So-called 'Heart Healthy' Seed Oils Can Make Us Sick" with Susan Flory.

A really nice interview with Susan Flory, whose "The Big Middle" podcast is about "Free-range conversations about living healthier for longer and demanding more from the bigger middle of life"

A cautionary, fascinating tale of how so-called 'heart healthy' seed oils can make us sick

On this episode of The Big Middle, the compelling case against seed and vegetable oils still being touted as ‘heart-healthy’. Those bottles of chemically-extracted fat that take up entire aisles of grocery stores are increasingly seen as hazardous to our health – key drivers of autoimmunity, macular degeneration and the modern plague of lifestyle diseases known as metabolic syndrome.

Even the major makers of soybean, sunflower, corn and other seed and vegetable oils are quietly backing away from them, well aware of the biological damage they can do.

Tucker Goodrich has been sounding the alarm over the health risks of seed oils for more than a decade. He suffered 20 years of gastrointestinal torment and much – scary – more that mystified his doctors. So he dug into the medical science himself, eventually pinpointing industrial seed oils as a villain in his sickness puzzle.

Tucker’s become a recognised world authority on the subject and I guarantee his Patient Heal Thyself story will blow your mind...

The podcast is here, with the usual subscription options, or listen below.

Also, we discuss this: Stephan Guyenet's "Malocclusion: Disease of Civilization" Series, if you want more information.

Stephan Guyenet's "Malocclusion: Disease of Civilization" Series.

 When Justin Owings posted a link to one of the posts in Stephan Guyenet's series*, he couldn't possibly have imagined the effect it would have on my life.

As someone who had stopped eating sugar in hopes it would have a beneficial effect on cavities (it did) I was primed for the message of this series, but I couldn't have imagined the effect it would ultimately have on me.

Since I mention it regularly, I thought I would provide links to the entire series, as it's been someone buried in the mists of time in the internet (it's from 2009!).


  1. "Malocclusion: Disease of Civilization"
    "In his epic work Nutrition and Physical Degeneration, Dr. Weston Price documented the abnormal dental development and susceptibility to tooth decay that accompanied the adoption of modern foods in a number of different cultures throughout the world. Although he quantified changes in cavity prevalence (sometimes finding increases as large as 1,000-fold), all we have are Price's anecdotes describing the crooked teeth, narrow arches and "dished" faces these cultures developed as they modernized.

    "Price published the first edition of his book in 1939. Fortunately, 
    Nutrition and Physical Degeneration wasn't the last word on the matter. Anthropologists and archaeologists have been extending Price's findings throughout the 20th century. My favorite is Dr. Robert S. Corruccini, currently a professor of anthropology at Southern Illinois University. He published a landmark paper in 1984 titled "An Epidemiologic Transition in Dental Occlusion in World Populations" that will be our starting point for a discussion of how diet and lifestyle factors affect the development of the teeth, skull and jaw (Am J. Orthod. 86(5):419)*....

    "...Over the course of the next several posts, I'll give an overview of the extensive literature showing that hunter-gatherers past and present have excellent occlusion, subsistence agriculturalists generally have good occlusion, and the adoption of modern foodways directly causes the crooked teeth, narrow arches and/or crowded third molars (wisdom teeth) that affect the majority of people in industrialized nations. I believe this process also affects the development of the rest of the skull, including the face and sinuses.

    "A Summary

    "For those who didn't want to wade through the entire nerd safari, I offer a simple summary.

    "Our ancestors had straight teeth, and their wisdom teeth came in without any problem. The same continues to be true of a few non-industrial cultures today, but it's becoming rare. Wild animals also rarely suffer from orthodontic problems.

    "Today, the majority of people in the US and other affluent nations have some type of malocclusion, whether it's crooked teeth, overbite, open bite or a number of other possibilities...."

    Two identical twins, the only difference is in dental treatment. From post IX.

Podcast Interview: "Dr. Cate Shanahan & Tucker Goodrich on the True Cause of Disease and How We Know This" with Brian Sanders

Excellent discussion with Dr. Cate Shanahan and Brian Sanders. Very fun!
"Today is a special show that I really enjoyed with 2 guests - Dr. Cate Shanahan and Tucker Goodrich. I had Tucker on years ago for episode 20 and he laid out the entire case against seed oils which was very compelling. Dr. Cate has been on twice already (more recently) and is a wealth of knowledge on many, many things, especially the dangers of seed oils and reinforcing the Sapien diet concepts. We cover how people get fat & sick all the way down to the mitochondrial level. We discuss the different players in this process including seed oils (or more specifically excess amounts of omega-6), refined grains, and sugar.

"We also do my favorite thing and look at all sides of the arguments. We use an article a seed oil supporter wrote as a tool to check in on the studies and claims cited. You won’t want to miss this one! It’s a long one, but we cover a lot, and there’s a bunch of great new info....
