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?
Grease contains a large amount of saturated fat. As for ice cream, added sugars are unhealthy too, but since a lot of other unhealthy foods don’t contain sugar we know it isn’t the only cause.
