In my house, we only use organic virgin coconut oil to fry with, except for my eldest, he prefers Olive oil, but he doesn't eat salads, I use the extra virgin olive oil on my salads. The following article is interesting to say the least. It doesn't go into all of the details about the oxidization of most oils, and the harm that they can cause, but you can delve deeper yourselves, if you want.
I will probably add Lard as an alternative to coconut oil, if I ever run out. Saturated fats are just the best for health, and finally, have now been non-villified, as anything to do with heart attacks. Therefore my eating of 1 tbs of Kerrygold only butter in my coffee, has now been proven to be excellent for health. Kerrygold is from non cafo fed cows, meaning cows that graze naturally, not fed rubbish!
