So my parents like to fry a lot of their veggies on PUFAs like grapeseed oil.

I don't believe in any of the reputed "benefits" of grapeseed oil, but my parents do.

I'm concerned about the oxidation of PUFAs when subjected to heat. How much of a concern is it? I'm trying to get them to switch to cooking under MUFAs.

Me personally, if I fry something, it'll be done extremely lightly in a saturated fat, like lard, butter, coconut oil or palm oil.

It wouldn't surprise me if MUFAS became toxic as well, when subjected to these temperatures.

That being said, just the very process of cooking alters the scientific make up of the food. I try to eat as little cooked food, as is possible.

This is something I've been worried about, too.

I found this, it seems to be from a reputable source:

I like ex virg coconut oil, but sometimes the coconut flavor isn't right for the dish. Ghee would probably work okay if I can find a good brand.

Then there's this suggestion on how to 'saute':

But what should I do with all the canola oil I just bought?

Wow - thanks so much for the reply and link!

I'm not sure if canola oil is that bad.. It's mostly monounsaturated (though it might depend on which brand of canola).

"Canola oil is about 21% linoleic acid, and 7-10% alpha linolenic acid; and alpha-linolenic acid is an omega-3 PUFA which should NEVER be heated."

^also I wonder if heating omega-3s is really worse than heating up omega-6's - are they really worse?

I think olive oil would be best. Coconut oil is saturated and not good for you to begin with.

It's not good for you if you eat half a tub. We're taking about small amounts meant for frying. But you prefer a less stable fat, like olive oil, because saturated fats are the devil (my apologies, I did forget about that).
