Hopefully, I have given readers something to consider in terms of refined oils. I see no evidence that refined oils are healthy, and to the contrary, there is substantial evidence that they are a negative. Simply substituting high-fat foods like nuts for oils would appear to be a health-promoting switch.
Let me add that all this evidence is linking refined oils to health, and not necessarily weight or fat gain. I am speaking strictly in terms of health, specifically cardiovascular health, here.
So why are all these health gurus and Paleo-ish gurus telling people to dump oil on their food? I have no idea.
Lastly, let me say that all this is not an original concept. Dr. Esselstyn states “no oil” in his heart disease reversal program. Art Devany said in his book that no oil is particularly good for you.
Given all available evidence, I think refined oils are neutral at best, and most likely oils have a negative impact on cardiovascular health.
