Which cooking oil is best for us? Why do I ask? Are we not bombarded with advertising messages telling us there is a healthy oil that is good for the heart? They talk of monounsaturated fatty acids (mufa), and polyunsaturated fatty acids (pufa) and of course, catch-us-words like omega properties. I am sure you, like me, try to understand this scientific jargon and conclude that any oil that has all these elements, must be good.
