I noticed that almost all types of cooking oil (vegetable oil, olive oil, peanut oil, etc) contain some saturated fat. Since saturated fat is known to be a contributor to heart disease, then could you simply remove the saturated fats from the oil to make it healthier?
We probably could, but I think it would be a lot of effort for a relatively small gain. If you’re concerned about saturated fat intake, the most effective thing to do would be to cut back on meat and dairy products, since those are much more potent sources.
I’m no dietician, but I can’t imagine cooking oil makes up a significant portion of saturated fat intake for most people, when you consider the popularity of dairy in all its forms in western cuisine.
