Are there any studies on the body's transition to saturated fat? Someone on here mentioned that the body replaces PUFA, and possibly trans fats, with saturated fat where saturated fat should ideally be.

If livestock fed a grain based diet have more stored n-6 PUFA, I would imagine this might also apply to humans fed a high-grain diet. Does anyone have any links to evidence for this? Thanks

Grain is high in omega-6s, it's not that it is promoting omega-6 storage. And it's more of a lack of omega-3s in the diet that causes low omega-3s. CAFO cows, pigs and chickens don't eat grass, so they don't get a lot of dietary omega-3s.

Doubtful you'd be able to remove just the PUFAs by removing the liquid fat. Fats are packaged as triglycerides, and aren't all PUFA, MUFA or satruated, they're usually a mixture in each triglyceride (3 fatty acids per glycerol). At room... (more)

Eat the fat. You're WAY overthinking this. The melting point of fats is normally manipulated in a hydrogenater. This adds hydrogen at the unsaturation sites in a PUFA, saturating it and making a synthetic saturated fat with a higher melt point.... (more)

Only refined isolated omega-6 PUFAs are problematic in my opinion. You can't really overeating omega-6 PUFA from whole foods, without significantly distorting one's diet.

Olive oil is fine for frying, sort of an urban legend that you shouldn't use it. Red Palm is more saturated than olive oil, which, in theory, increases the stability of it. I wouldn't use it for high heat frying as you'll be burning the... (more)

Rice bran oil is popping up everywhere - is it a thumbs down from the Paleosphere? It is stable at high heat, but I suspect it has the same problems as 'seedy' oils. Avoid at all costs? I submit to the wisdom of the Jedi Masters.

Fats are on a continuum. Rice bran oil is about 33% PUFA, so it's better than something like soybean oil or corn oil but worse than beef tallow or coconut oil.
