Here’s an interesting post by Scott Kustes of the Modern Forager on Ten Oils And How To Use Them. It’s a follow-up to a guest post that Scott wrote recently for Mark’s Daily Apple on The Tropical Oils, Coconut and Red Palm Oil.

In the post on Tropical Oils, Scott explains….

Saturated oils are nearly impervious to oxidation and degradation. Basically, there are four types of fat: saturated, monounsaturated, polyunsaturated, and trans. Trans fats are just bad news altogether, so I’m not even going to touch on them. Every fat molecule consists of a glycerol molecule joined to three fatty acids, as this image shows. The degree of saturation refers to the number of double bonds between carbon atoms on a single fatty acid. So looking at the top two fatty acids, you see that no carbons are double bonded; all are bonded to hydrogen molecules, hence this fatty acid is “saturated” with hydrogen. The bottom fatty acid has a single double bond, meaning that it is monounsaturated. A fatty acid with two or more double bonds is polyunsaturated. These double bonds are susceptible to attack from free radicals, which degrades the fats, both inside and outside of your body. Obviously more double bonds equals more bonds available for attack. Heat, light, and oxygen all cause damage to fats in proportion to their degree of unsaturation. Therefore, polyunsaturated fats are the most unstable, with monounsaturated and saturated fats falling next in line. Coconut oil is so stable that after a year on the shelf at room temperature, it has been shown to have no measurable rancidity.

He concludes…

It looks like saturated tropical oils in a landslide. I know that my consumption of palm and coconut oils has improved my skin, my energy levels, and my body composition. Given the scientific facts and my own experience, I’ll stick with cooking in palm and coconut oils and adding olive oil (monounsaturated) to my salad dressings and vegetables.

Then in the post on Ten Oils And How To Use Them, he discusses a wider range of fats. These posts are definitely worth reading, especially if you’ve been cooking your meats and vegetables in olive oil as I had up until recently!
