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?
You should probably spend a bit more time avoiding xylitol then, if that’s your reasoning. Sorbitol isn’t toxic to dogs for the most part. Xylitol on the other hand is.
