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?
I think the cost/benefit ratio is the main issue. Splitting oils to remove the saturated fat is not a simple process, especially when the easier answer is “use an oil naturally lower in saturated fats” like rapeseed (canola).
You don’t think they could market it as a healthier oil and sell at a higher price?
Eh I think they’re two different markets. If you prioritize health over taste, go for the cheaper, natural rapeseed. If you’re prioritising taste over health, most people are not going to be bothered by the sat fat, and would prefer an unadulterated flavour.
I believe you have to distil the oil, so it’s definitely going to be heated. You can be sure that the processing required to remove the sat fat is going to change the flavour and texture, while also somehow making it worse for you than either.
I think the point is those oils already exist and are cheaper than refining other oils.
