... well neat, apparently saturated fats aren't actually unhealthy???
If I'm reading this correctly, saturated fats aren't actually unhealthy, trans fats very much are, polyunsaturated fats are actively _beneficial_, and so e.g. replacing butter with polyunsaturated fats became health advice even though butter isn't actually unhealthy, likely due to conflation with the health harms of trans fats?
> polyunsaturated fat is more beneficial to heart health than any other major macronutrient. Saturated fat, on the other hand, turns out to be neutral from a heart health perspective when compared to the average diet—so that campaigns which prioritize reducing saturated fat consumption, rather than focusing on foods and overall diet quality, are a misplaced and misleading public health strategy. [1]
> Saturated fats are not associated with all cause mortality, CVD, CHD, ischemic stroke, or type 2 diabetes, but the evidence is heterogeneous with methodological limitations. Trans fats are associated with all cause mortality, total CHD, and CHD mortality, probably because of higher levels of intake of industrial trans fats than ruminant trans fats [2]
> replacing a mere 5 percent of saturated fat calories with unsaturated fat would reduce one’s risk of heart disease by a whopping 42 percent. Replacing only 2 percent of trans-fat calories (the kind found in packaged pastries) with unsaturated fat would reduce one’s risk of heart disease by 53 percent [1]
