A recent article on fats came to my attention. The article shed some light on the overall fat issue for me. It stated that vegetable oils such as corn and safflower, though high in poly-unsaturated fats, were prone to oxidation, which releases free radicles and increases LDL (low-density-lipoprotien) cholesterol. These fats also do nothing to increase the level of HDL (high-density-lipoprotien) cholesterol. In effect, they do you no good.
Trans-fats are fates that have been hydrogenated. The process makes them solid and easy to work with, and retards spoilage. These fats directly contribute to an increase of LDL cholesterol and add no HDL cholesterol to the blood.
Saturated fat, as the most knowledgeble gentleman and friend from Fort Worth stated, is an animal fat and adds LDL cholesterol directly to the bloodstream. It is to be used in moderation.
Surprizingly, olive oil, while adding no LDL cholesterol, is also neutral with respect to HDL cholesterol. It doesn't affect the cholesterol levels in the blood. It is still a calorie-dense food and should be used in moderation. This is true of all the seed derived oils, and fruits such as avacadoes.
According to the article, sunflower oil both lowers the LDL cholesterol, and increases the HDL cholesterol in the blood, making it the healthiest of consumable fats. It is an oil that withstands high temps and is absolutely neutral in flavor. That is the oil I use whenever I need a neutral oil, or one to fry with. The second oil I use is EVOO, for its flavor. Finally, I use butter in small amounts, again for flavor. Though it can contribute LDL cholesterol, it doesn't decrease the HDL cholesterol as do trans-fats such as shortening and margerine.
I don't use Canola oil as there is too much controversy about it for me to trust it. There are people on both sides of that argument, with each side being extreme in their opinions. One side says the stuff is hte greatest fat on the planet. The other says it's the most dangerous fat we can put in our bodies. I'm not taking the chance. Besides, sunflower oil production is second only to canola oil, making it cheaper than most other cooking oils.
