O3/O6 ~~ 1:2, unlike olive oils 1:12
Secondly, I like dislike the taste of canola less than the taste of olive oil.
The Paleo religion thinks that nothing in the last 10,000 is any good. What do they object to, other than modern.
Food grade canola oil is centrifuge pressed in a massive centrifuge, not chemically extracted. The one that I designed the foundation for had 35Kip rotor operating at 3450 rpm, with maximum 1 kip unbalanced load at 24 inches off center. That will shake a the 100 kip machine and 1400 kip base and battered pile base. The oil just flows out, and is shipped to a bottling plant that also bottles other products. The mash is chemically rinsed for the chemical grade products. No one would eat the chemical grade stuff: it has a gray color, that does not come out cheaply. The quantity of canola oil used for food is small compared to total production.
The only down side to Canola may be traces of chemicals, but what about olives? are they grown without chemicals?
And none of the readily available olive oil is considered good. I am not about to go into down town Edmonton in search of olive oil.
My ancestors, that I remember from my youth did not have major weight issues; however, it was a concern. I come from long generations, of rural living, farming tradition families. Both of my grandfathers were massive men in their youth, 6'4 and 6'5, and an axle handle wide at the shoulders. My grandmothers were both smallish ladies, 5'4 or there about. On their wedding photos, they look like dwarfs. adjacent.
But I have always had a sever weight problem, always food issues. Some were learned behaviors, and some seem to physical/chemical issues.
