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.

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)

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.

Nuts are good sources of PUFAs. Fish is as well. PUFAs are the least common type of fatty acid found in your fat, so you don't need much in your diet at all. If you eat fish and nuts, you're set for your PUFA requirements.
