I'd like to see the evidence for that. Given the evidence we have against saturated fat, I would expect better health outcomes for people fed potato chips fried in vegetable oil over butter. Every time we swap saturated fat with unsaturated fat, even in metabolic ward studies, we see better outcomes. When I see someone saying that butter is somehow better, I like to see what evidence they've used to reach the inference despite all the evidence against that position. Unfortunately the position usually just cashes out into "but I like butter".
