There's a flaw with that kind of question because our scientific understanding of diet is nowhere near complete. Metabolism and the microbiome are crazy complicated. It's better to do experiments like actually cutting out seed oils to see what happens. And the weird thing is that their community has hundreds of posts about curing weird autoimmune diseases or digestion issues https://www.reddit.com/r/StopEatingSeedOils/comments/1bqpel7/so_thankful_for_this_sub/

Idk, I think it's compelling enough I've been changing my diet. I definitely get much less cravings for things, I actually just ended a 36 hour fast I did simply because I forgot to eat.
