Do seed oils block cholesterol to vitamin D? Vitamin D as sunscreen Sunburn resistance of people who don't eat seed oils

Summary by Google's LLMIn this video clip from Low Carb Down Under, Dr. Paul Mason presents a theory linking the consumption of industrial seed oils to a higher susceptibility to sunburn

Key Arguments and Claims:

  • Vitamin D as Natural Sunscreen: Dr. Mason states that the body naturally vitamin D as a protective shield against UV/UVB radiation damage to DNA, rather than strictly for bone health
  • The Cholesterol Connection: He references Ancel Keys' historical "Seven Countries Study", highlighting a data point that individuals with higher sun exposure had lower blood cholesterol levels. He explains this occurs because the body uses cholesterol to synthesize vitamin D
  • Interference by Plant Sterols: He argues that plant sterols (phytosterols) absorbed from dietary seed oils interfere with normal cholesterol chemistry, specifically disrupting the skin’s ability to synthesize vitamin D
  • Anecdotal Evidence: While acknowledging the evidence is largely anecdotal, he points out that a vast number of individuals on ketogenic internet forums report a noticeable resistance to sunburn after completely eliminating seed oils from their diet.

I was in error, the short clip is actually from https://www.youtube.com/watch?v=NVqNO8rgYKk a informal 5 minute talk he gave at a keto conference (preaching to the choir so to speak), but it is based on his more formal lecture I discussed above.

Honestly I hate youtube clipping, it confuses everything.

I did watch the full lecture you linked, but I did notice it was different from the short clip.

Its a good talk and well cited. It also matches sources I had found independently with the help of my fiance who has a degree in chemistry and in nursing (alas, I am just a history fan who likes to argue).

But I'd like to point out I did say

It's fundamentally a bad line of reasoning that only means something to people deep in the weeds of carnivore food science.

Does my original point make sense?

I do think there's interesting science here and I honestly and truly don't want you guys getting caught in grifter style clip farming, rage baiting, circle jerkings. Dr. Mason seems to be a pretty good source, but his newer content is slipping into this sensationalist format of communication.

A lot of his newer stuff has lines like "what mainstream medicine doesn't want you to know!" "Are you smarter than you're doctor?" Which I admittedly haven't seen those videos yet, but that's a red flag that a lot of carnivore content seems to lean on.

I get it, that's how the algorithm works, but I think good information can thrive by just being packaged well.

Sure, you may disagree with the packaging but we try to look at the content. I was very disappointed to your treatment of Dr Georgia Ede

Update - you might want to just restrict yourself to the papers we discuss - https://startrek.website/search?q=%5Bpaper%5D&type=All&listingType=All&communityId=778784&page=1&sort=New&titleOnly=true

Then the format is very academic and cited.

rage baiting, circle jerkings

Last warning. No more ad hominem attacks

[–] nagaram@startrek.website 2 points 4 hours ago (1 children)

Still not an ad hominem.

Do you want me to compile examples? I'm trying to explain my miss givings with carnivore content creators and there is employment of these tactics in their promotion of content.

I will admit my use of circle jerk was crass and for that I'm sorry, but I'm genuinely wanting to talk about what I perceive to be a bad mark on your community.

This is reasonable.

Yeah, but I can't really fix algorithmic headlines from the short end of a super niche community. I post the actual papers here too. I even change headlines to make them more factual when I can (especially the testimonial videos).

And genuinely, I deeply appreciate the work that you have done to try and rectify the clickbait aspects. It has made the content more approachable for me. I admit I'm kinda of a pain when I get curious cause I wanna fight a little when its challenging to what I know and a lot of this is pretty challenging. You've been a wonderful ambassador for this lifestyle of yours.

And genuinely, I don't know what I want you and your community to do about the algorithm gaming. The examples posted here haven't been egregious, I'm just annoyingly sensitive to it. They mostly seem to be real scientists with real science to push, but are forced to play the algo game for reach.

Maybe I just wanted y'all to be aware of it? Maybe I wanted to be aware of it? That this is part of this strange conditioning we have thanks to reddit brain to want to immediately get upset about something kinda dumb to be mad about. I don't really know.

Hopefully you got something out of our interactions because I got a lot.

Fair enough, we are aware! I'm afraid nobody is going to be dropping hundreds of millions of dollars to find out why zero-carb meat eaters don't get sunburns. The closet we have to that is the Baszucki family dropping 400m into metabolic psychiatry research. Fixing bipolar probably is a greater net positive for humanity, so I get it. If i was god dictator of earth there is a bunch of foundational science I would fund.
