Olive and avocado oil, flax seed oil, oil from fish and meat. I think there's a difference between eating palmitic acid that's part of a larger fatty acid profile in meat, and being conscious of just how much saturated fats you're eating, versus refined palm oil that's mostly been refined down to palmitic acid itself. If you're eating peanut butter, you might be literally eating refined palm oil by the spoonful, versus a relatively small amount of palmitic acid in meat.
