Gets, I can't answer that, but I think the point of the study is that no oil is healthy, just that some less unhealthy than others. Extra virgin olive oil and coconut oil cause arterial inflammation, but not as much as other oils. It's possible that there is some rare oil that is healthy, an oil that hasn't been subject to as much study, but it's not one of the major oils that are commonly used. From other studies, meat, chicken and even fish cause inflammation too. So does dairy and sugar. That's why the physician who puts out these videos promotes veganism. I recently started veganism and I've noticed some positive results, but I need to give it more time before they show up in lab tests.
