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 tried that in the 90s, it went poorly: https://en.wikipedia.org/wiki/Trans_fat#History
I am not suggesting we add any additives, only to remove an existing fat from the mixture that makes up cooking oils.
