N=1 on Omega-6 and Sunburn: Can Sunburn be Reduced?

I got the following message recently, out of the blue:
This was, I presume, in response to a few tweets on this topic, which I had been discussing with a few other people.
My correspondent wishes to remain anonymous, for reasons you'll see below, but I was curious to see what his experience actually was, and why he decided to look into this. He agreed to let me post the exchange we had.

[Edited for readability; PUFA = PolyUnsaturated Fatty Acids; n-6 = omega-6 fats from seed oils, n-3 = omega-3 fats from fish or certain seeds.]
I do have a question for you though, what did you do to cut back on omega-6, and how long did it take for you to notice a difference?

Thanks for this!! Well I started to look and consume less n-6 after reading your posts!!
I used to get some serious sunburn on my long runs. So upped n-3 and consumed less n-6... It's actually pretty amazing to run without a shirt, for three-plus hours and have NO sunburn at all!!! That's why I enjoy your posts!
I think Noakes here in South Africa has done a great job, but you are one of the few that emphasize PUFA/n-6 as an issue...I see many people here in SA do Banting, but use copious amounts of sunflower oil...Noakes should address this...
My old man similarly was on Noakes banting diet, but they were extremely high on n-6, so I showed them your tweets... They are doing stellar now... With my dad as with me it took as long as 6 months to see a difference, but I should add that we lowered n-6 and also upped n-3, with krill oil.
Your tweets have resulted in our entire town cutting back on PUFA's. In fact, I told some guys about your tweets and I said that I would rather be high carb and low PUFA/n-6 than low carb and high PUFA/n-6.
Thanks so much for the reply! You should come visit and run Comrades here some time!!
👍🏼
Reports like this are what makes doing this work worthwhile. Thanks for letting me know!

I'll see if I can pass this along to Professor Noakes, as I'm sure he'd be fascinated to hear this report as well.
