Mice that ate moderate lard had more of a type of immune cell (M2 macrophage) in their fat tissue that is linked to reducing inflammation.

Mice eating lard had more of a type of immune cell in their fat tissue that calms inflammation, and fewer of the type that causes inflammation, compared to mice eating plant oils.

When mice ate a moderate amount of lard (pig fat), they stored less fat in their fat tissue than mice that ate the same amount of plant-based oils.
