So if you substitute say, olive or canola oil for butter or lard, you'll improve your heart health by reducing the constant irritation to your blood vessels"

I would have thought that butter and lard were worse not better? They are harder at room temperature, no?

Dietary saturated fat content was derived primarily from dairy foods in both studies. Beef fat was only a minor component of the saturated fat profiles of the LCHSF and LCLSF diets and there was only a 0.6% differential in saturated beef fat intake between these two diets. Hence, the present findings suggest an interaction between saturated fat and one or more nonfat components of beef on lipoprotein metabolism. Because there is little evidence for a major role of dietary protein composition on lipoprotein metabolism, this interaction is not likely to be caused by specific amino acids within beef protein. However, saturated fat might be interacting with a micronutrient or other component that is more abundant in beef than in other food protein sources. For example, systemic iron stores have been associated with altered lipid metabolism and there is evidence that heme iron absorption is substantially increased by saturated fat and, in particular, stearic acid, which is abundant in dairy fat.
