What's an industrial seed oil? I kind of like grape seed oil, sunflower seed oil, mustard seed oil, and a couple others. Don't like how flaxseed oil acts with my bod. But far as I know, all those are real seed oils
The top four vegetable oils consumed in the United States are soybean, canola, palm, and corn oil. These are referred to as refined, bleached, deodorized oils – or RBD for short – because this describes the process by which they are manufactured.
In my book these are industrial seed oils .
When I am in a supermarket I count industrial seed oils as
the cheap stuff used to make processed products nearly all of which will contain the above. or its european equivalent
cheap supermarket oils such as canola , vegetable oils,corn oil mazola, including cheap olive oils, and sunflower oils.
and the " healthy processed products - crisp n dry, "fry light butter flavour cooking spray", margerines light spreads, cholesterol lowering packets of anything , flora , benecol , I can't beleive its so good light spread
I would put cold pressed quality oils in a different category - things to be enjoyed as flavourings to my favorite foods.
My personal mantra is that if I can see how I might get oil out of it, because it feels oily to me- then I'm ok to use it as an oil if the oil has been cold pressed. So for me that would be olive oil, avocado oil, coconut oil . I can't say I've ever explored pressing sunflowers, mustard seeds , flax or sesame seeds to get the same result however I can see how that might work and as I happily eat most of these things raw, I wouldn't be too concerned about having a bit in my diet to taste.
Personally I would be very careful to try to limit the total volume of omega 6 polyunsaturated fats in my diet , from whatever source . The research suggests that one should try to eat 1:1 omega 3 to omega 6 oils . Its something to do with some of the bad qualities of omega 6 being absorbed by the good in Omega 3 ( though I can't pretend to know the details of the research )
Its actually quite hard to achieve a balance unless you actually like for example cod liver oil, and you eat quite a lot of oily fish.
A standard diet including processed food these days can be as much as 1: 20 / 30 omega 3 to omega 6 .
I find I can get to 1:3 ish fairly easily using real foods but it takes a lot of conscious thinking about it .
So for me I eat real foods - butter, duck and goose fat, lard coconut oil, and olive and avocado oils and give the rest a miss, other than the occasional splash of a specialised oil such as sesame for flavour. I hope that helps !
