All I know is that my great grandparents used butter and lard every day. They lived into their late 90s.
The next generation ate margerine and crisco and fell over of heart attacks in their 50s.
Besides.... lard and butter taste better than hydrogenated vegetable oil
Butter does taste better and that is what I use. And you are right about the age too. My husband has heart and weight issues (pc talk LOL) and I am afraid to use the lard.
Way back when, we had a pie eating contest to see whose pie crust was better: my aunt’s or my mother in law’s: lard vs.Crisco. Auntie’s lard won! Of course, I was biased with my vote cuz I never did like my EX mother in law.
