I know it seems like I obsess on this seed/vegetable oil issue. It is just curiosity. Everyone here has heard of low carb, vegan, carnivore, keto, plant based, etc so I do not post on that. This oil issue is still new to me. My brother just had an angiogram and needs 2 stents put in so there is that. They had to wait because he has kidney issues and need to manage the contrast media carefully.
Summary: Omega-6 linoleic acid may be very harmful. People eating very high saturated fat or very high complex carbs can be very healthy.

No heart disease obesity, diabetes, macro nuclear degeneration. 27 min. What mattered? Om-6 PUFA!
29 min. How the on-6 biochemistry works and harms. Mitochondrial dysfunction. Insulin resistance.
33:45 isocaloric diets rats 3 groups. only om-6 varied. beef tallow om-6 4.4%, olive oil 7.7%, safflower oil 36.6%. All on high fat diet of 59% calories. 3 weeks.
