“So, are you exercising much?”

“Oh yes doc, I get out for a run most days of the week.”

“Wonderful news, got to look after your heart.”

“Yeah, and with my new butter churning bags, not only do I get to stay fit, but I also consume ungodly amounts of butter!”

“Sorry what”

Eating butter is good for your heart. As long as your triglycerides and HDL (AKA "good cholesterol") are low, elevated LDL (AKA "bad cholesterol") is associated with lower all-cause mortality.
