Neil,
>>Cotton seed oil is light years ahead of all the others.
I don't think that matches the consensus from authorities outside the cottonseed industry.
Pressed olive oil has a very high monounsaturated content and does not need to be mixed, softened or chemically altered. Some of the very best olive oils are not even filtered so you get fragments of olive flesh in your oil. Whereas cottonseed oil needs chemical extraction and modification to fully hydrogenate it, followed by mixing because the processing leaves it too hard to be used as a food oil. To me it is the difference between fresh squeezed orange juice and an orange flavored drink. It is the price that makes the processed version attractive to food manufacturers, not some intrinsic quality.

"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
