However, it seems very implausible (or impossible) that humans evolved to need, or benefit from, industrially processed sunflower seeds and olive oil.
How has the total fat in your diet changed? I find it much more plausible that dramatically reducing cheese, cream, whole milk and full fat yoghurt has helped, than that replacing 20mL of cream with 20mL of sunflower oil has helped. It sounds like you have reduced fat overall - why then attribute the benefit to the vegetable oils / fat profile, specifically?
