Trans fatty acids. Who hasn't heard of the danger this type of fatty acid causes, creating a serious risk of heart disease? Let's look at that benign looking canola oil bottle sitting on one of the shelves in your supermarket.

What can you notice from the above chart? Notice the level of omega 3 fatty acids that is found in canola oil? Now ask yourself this question: what happens to that 11% of omega 3 fatty acid when it is subjected to heat-intensive processing that the canola oil as a whole is subjected to? Well, rancidity (and all the nasties that it causes in our body aside for a moment), the unpleasant odour that results through this processing would have to be well taken care of or no sane consumer would ever go near such an oil, let alone buy it. Enter the process of deodorisation, turning a large amount of canola's omega-3 into trans fatty acids....extremely unstable fatty acid remember!
I know for a fact that my ancestors consumed as well as manufactured cold pressed extra virgin olive oil. It's an oil that goes back thousands of years. I make 40 litres in a good year out of 14 olive trees that I have. I'm not suggesting for a moment that olive oil is somewhat better or healthier than eating an olive. Naked fats, all naked fats are powerful ingredients that need to be treated with respect, as they can have a profound effect on our bodies.
I personally like to stick with what I know and what has a track record behind it. Each to his or her own to consume whatever they see fit for their health and the health of their loved ones. An olive (especially the Sicilian olive in brine) with its L casei bacteria is great for one's health (especially mouth / oral health),...so is an avocado and a formidable powerhouse that is an Aussie macadamia nut...all these three foods are kings when it comes to omega 9 fatty acids.
I just had to come back and make an edit here, after looking closer at the above chart. The safflower oil I know from memory to be very high in the polyunsaturated (unstable) omega 6 fatty acids. The chart above has its omega 9 as being the highest,..that is simply wrong,..possibly a mistake by whomever put that chart together.
