Difference Between Naturally-Occurring PUFA And Man-Made?

[Luann]

Does Peat draw a difference between eating a polyunsaturated fat from a natural source, like a peanut, rather than pressed from a seed, bleached, etc.?

For example, is it better to eat flax seeds in something than it is to have "mono and diglycerides"?

He's said that it doesn't matter much if the PUFA are degraded when you eat them, because even fresh PUFAs will degrade pretty quickly when exposed to warmth, oxygen and catalysts inside the human body.

Most naturally occuring PUFA's are accompanied by a relative amount of Vitamin E, to prevent oxidation. It's why nuts and seeds are "good sources" of vitamin E, even though it is probably not enough to compensate for the damage.

This isn't true though. There's a study about it on this forum. The vitamin E is trapped by the anti nutrients in these nuts, and even the oils from the nuts interfere with the tocopherol content.

That's itneresting. So even the vitamin e in unsaturated foods is not bioavailable.

It appears so. I think olive oil is one of the best options, but then you are consuming monounsaturated fats. It's hard. There's supposed to be a lot in liver, but I'm not sure about the content of E in the liver of mass processed meats these days.

I eat almost no vitamin E.

You can get some vitamin e from low PUFA sources like mango, raspberries and prawns/shrimp.

Spinach has a bit but the oxalates can mess with your calcium.
