> research [] conducted in the Philippines and Ecuador These are tropical countries where coconuts are an evolutionary-appropriate part of the food supply. Coconut oil is mostly saturated, and is stable at human temperature. Western countries switched to polyunsaturated "vegetable oil" as a dietary staple. Sometime in the 1940's the paint industry figured out how to make their paints and stains from petroleum distillates. Originally the paint industry used linseed oil and soybean oil for most of their products. The unsaturated components of polyunsaturated seed oils combine spontaneously with the oxygen in the air to form a hard film [0]. The paint industry essentially said, "farmers, thanks for your products all these years, best of luck in your future endeavors." The seed oil conglomerates [1] (ADM, et al) were screwed. Then they realized they could just rebrand their products as "vegetable oil". Ancel Keys was hired to convince people of the hazard of saturated fats... Omega-6 degrades to prosteglandins [2], which are molecules of stress and inflammation [3]. Omega-3's are more unstable than Omega-6 oils. IMHO, the ω-3 / ω-6 ratio doesn't really matter - the most important thing to get inflammation under control is to limit "vegetable oil" intake. Olive Oil's okay, if it's genuine. Unfiltered olive oil is even better. But wikipedia says the American Heart Association still recommends getting your daily dose of inflammation precursors [4]. Not impressed.

"Evolutionarily appropriate food" doesn't mean anything because it doesn't answer the question of whether something is correlated with better or worse health outcomes when put to the test. Just surviving into reproductive age isn't the standard we have for ourselves. We want to live into old age. Instead of using the narratives in your post to reach a conclusion, your question should be: what does the science show on unsaturated fats and vegetable oils? What is the direction of effect on our health? So far it seems that vegetable oils like canola oil are neutral at worst and health-promoting at best. Here's a review of the metaanalyses on the topic: https://www.the-nutrivore.com/post/a-comprehensive-rebuttal-to-seed-oil-sophistry https://www.the-nutrivore.com/post/a-comprehensive-rebuttal-...
