The Institute of Shortening and Edible Oils (ISEO)
iseo.orgIn the field of of obscure organisations with unlikely-sounding names, my favourites are the Institute of Measurement and Control, which sounds a bit like a 1984-esque surveillance agency:
And the International Earth Rotation Service, who are responsible for making the planet go round:
Discovering The International Earth Rotation Service a few decades ago is what made me diligent in paying my taxes.
I use polyunsaturated oils to attempt to preserve the wood used for my raised garden beds. While vegetable-oil preserved wood might not be as long-lasting as a modern chemical stain, modern stains have various amounts of heavy metal, which I don't care to put in close proximity to plants I intend to eat. The catalogue has a paint sold for raised beds, but discarded vegetable oil is free.
Paints and stains were traditionally made with linseed oil/soybean oil (and other similar thin oils) because these combine spontaneously with oxygen in the air to form a hard film. Modern stains are made with petroleum distillates.
Dietary polyunsaturated oils facilitate the creation of lipofuscin [0], the age pigment. Dietary polyunsaturated fatty acids also drive lipid peroxidation [1] chain reaction, whereby unstable unsaturated oils combine spontaneously with oxygen in the body to break down in an uncontrolled manner. The end products of lipid peroxidation wreck havoc by combining with proteins to make "fluorescent polymerized compounds" [3], etc. Eating polyunsaturated fat won't make you fluoresce, it'll just make you old prematurely.
The Omega-6 polyunsaturates are especially good for facilitating inflammation, due to their use to create Prostaglandins [2].
I do not consider polyunsatured oils edible, and read labels to avoid them.

You avoid refined oils specifically, or any foods containing poly-unsaturated fat? How about omega-3?
I avoid refined oils that are high in polyunsaturated oils. This mostly means seed oils from non-tropical seeds: canola, soybean, corn, cottonseed, grape seed, etc.
Palm oil has a significant percentage of Omega-6 oil. If it's in whatever's available to eat I don't worry about it too much. I understand Coconut oil is mostly refined without solvents, and that the refining process mostly has the effect of removing the allergens. Trader Joe's has a partially-refined low-odor coconut oil that I sometimes pick up. Extra virgin olive oil [EVOO] is okay in moderation; I prefer 'unfiltered' olive oil to plain EVOO.
Chicken fat is mostly polyunsaturated, as is pork (reflecting the fats in the animals' diets), so I try to avoid those fats too.
I never noticed a benefit from Omega-3 consumption. Omega-3 is an unstable polyunsaturate too. Avoiding the Omega-6 oils improves my ratio of Omega-3 to Omega-6 without any other efforts on my part.
Looks like they are a lobbying group. I thought at first (because of the initial "I" in their name) that they were an international body. Edible oils are an important source of calories in most developing countries.
My understanding is that most vegetable oils (other than olive oil and coconut oil) are probably pretty bad for us.
They're terrible. Dr. Cate Shanahan is a great ressource for learning about this. I can provide further references but based on my research and experience I'd say they are the biggest contributor to the chronic disease epidemic.
Also, Dr. Ray Peat http://raypeat.com/articles/articles/unsaturated-oils.shtml
I'm not a follower of him but I wanted to plug this excellent interview: https://youtu.be/jqhlIOt5sUw
Such a pleasant manner of speech and breadth of knowledge.
Nice, that just scratches the surface. Naturally, you probably won't agree with everything he says, but I've learnt a lot from the way he approaches questions.
There's a lobbying group in DC specific to ice cream flavors! They also do the real milk slogan.
