I've been cooking with olive oil for years. I don't really like coconut oil unless I'm cooking something that needs a little coconutty flavor. I've seen people on here saying it's bad, but I love it. I mostly cook at medium heat, if the oxidation is the problem. I read recently on I believe MDA that even oxidation of olive oil really isn't that bad/ doesn't happen (I'm not much for the science aspect of paleo, I'm more about feeling what's best for you). I like olive oil, I use it a lot. So, what's the deal?
I am just starting into this whole paleo diet thing and I am finding a lot of mixed messages about oils in general. Some say no olive oil, others say yes for marinades and dressings, others say it's OK for cooking (medium heat at most). Then for coconut the same, some say yes because it's heat stable and natural others no because of it's lack of omega-3s. I am taking all of this with a grain of salt (so to speak ;) ) My motto is everything in moderation especially getting fanatical about any diet plan.
I think the right answer is somewhere in between, but the more natural you can go the better. I think alot of what ailes us is down to all of the processing that our comercial food gets. Including most of the meat in the grocery store.
Eating the foods the way nature made them is sure to be better for us in the long run.
Considering that the Ithaca, Greece bluezone (area where population is demonstrated to live to 100 frequently with little disease) distinctively use a lot of it, I can't really see an honest objection. Marks Daily Apple did a large posting on olive oil as well, and in it he mentioned that it is very heat stable.
Nothing wrong with Olive Oil, for cooking, it's a good oil, it's not as unstable as other people are suggesting, like you say, there was MDA article on this. I like the flavor, but it's not a neutral oil, so some people prefer to combine it (spoonful of extra virgin olive oil) with other oils (ghee) for things like mayonaise. I don't know how the omega 3:6 ratio compares to other oils, but it's reasonably priced for a healthier option of oil. Other oils that are reasonable in price and OK are butter and lard here, so those are my main oils.
I use lots of olive oil with salads, it is a great choice of oil. It has been a staple of some excellent diets, specially for people in Greece and other Mediterranean countries. I do not cook or fry with olive oil though, because its reaction to heat (oxidation) is not the best.
The main thing I don't like about olive oil is the somewhat high n-6. it's fine in moderation, but I don't make it a significant source of calories. I would advise you to find another cooking oil, but still use olive for the taste after cooking is done. Ghee/butter and tallow are great options to cook in.
A kind of a belated answer! I am Greek(specifically from Crete) so I know olive oil! Cold-pressed,extra virgin olive oil can be used for cooking but it is not ideal because it has a very low smoking point.Practically,it gets burnt quickly and burnt is bad.It is best enjoyed raw as a dressing or used when baking meat or fish.
