Short article from the blog Whole Health Source on olive oil. http://wholehealthsource.blogspot.com/2008/04/olive-oil-buyers-guide.html
his recommendation to only get EVOO is off base tho. Cooking w/ EVOO degrades the oil and makes it no different than just olive oil. It might be a very, very small amount better, but not enough to justify the difference in cost.
To expand: The breakdown of MUFA, PUFA, and SAT is fairly similar. Macadamia oil has a ratio of 6.3:1 of O6:O3, and olive oil is slightly higher at 13.1:1 Interestingly enough, Cordain is a fan of canola oil, due to the high MUFA content, and O6:03 ratio of 2:1, which (he describes) as being optimal. This is taken from Cordian's The Paleo Diet for Athletes
I was at Costco today, and looked at their olive oil. Didn't notice any certs anywhere on the label; I'd hazard a guess that you'd be paying a hefty price in a premium shop for high grade olive oil.
I may be reading that ratio wrong but I always thought Mac Nut oil had more sats than polys... http://vitanetonline.com/forums/1/Thread/708 EDIT: Nvm. I'm an idiot.
They do. 16.5% SAT to 1.9% PUFA. The ratio I listed refers to omega-6 to omega-3, both of which are MUFA. That website lists the O6:O3 ratio as 1:1, which is surprising.
Yeah, I've got the Sam's Club "select Premium" brand and "Omaggio" brand that I bought at Sam's. Neither of them has a cert anywhere either.:icon_neut
