Lard and Poultry Fat

I'm reading Goose Fat and Garlic and have been inspired by the book to cook with lard and poultry fat. I usually discard the fat in the trash, but no more. Is it healthy? Who knows? There's always a big hoopla of what's good for you and what's not. One day eggs are bad and then the next they're good. The same goes for lard. In my opinion it, it should be everything in moderation which brings me to what a balanced diet is. Who knows what that is either? But the way I see it, meat should only make a very small portion of meals with the majority of the plate taken over by grains and vegetables. So if I follow this rule and exercise regularly, cooking with lard or other animal fat should be okay. Right?

Rendering pork fat...
Almost done...
Save the crackling. No waste.
