I do agree. There is literature to support that olive oil is more 'frail" and loses some of it's beneficial value by being heated to a high temp. Personally, i still use a mid-grade olive oil (Trader Joe's) to cook with and a high quality olive oil (Frantoia) to serve with. i also use virgin coconut oil. It is worth noting that you must be very careful with the quality of coconut oil (as all oils). Please see this attachment by Cocoon Nutrition.
Most Coconut Oil Sold in the United States is Refined, Bleached and Deodorized
Most coconut oil sold in America is made from copra. Copra is the dried meat of the coconut which is left in the open to dry. Mold may grow on it, flies may land on it, and the meat turns brown and rancid while it dries. The oil industry does not worry about this, as they will "clean the oil up" at the end to remove these unfavorable constituents. Once the meat of the coconut has dried and shriveled it is easily removed from the shell and the oil is pressed out. Many companies use solvents to help in extracting the oil from the meat. Once this crude oil is produced and the solvent "reclaimed", they then add lye to the oil. This step in the refining process will drop out free fatty acids, some of the Vitamin E, as well as other nutrients and components. These items drop out as soaps to be filtered. Then they put the oil through a bleaching process which will turn it from the brown rancid color to a nice white/clear color. This process also eliminates more vitamin E and other nutrients. And then lastly they deodorize the coconut oil by bubbling gas through the oil at high temperatures while pulling the vapors off with a vacuum. This will eliminate the bad taste and smell of the crude oil it came from. In the end you have a tasteless, odorless, coconut oil with only fatty acid chains remaining "seasoned" with traces of solvents and residues from the refining process. If the coconut oil you have used in the past does not taste like coconuts, even though it was claimed to be organic and cold pressed, then you can be sure it is not a virgin coconut oil, and most likely it is a refined, bleached, deodorized coconut oil.
