In lab-grown fat cells and immune cells, adding taurocholic acid made the fat cells store less fat and turned immune cells into a type that reduces inflammation.

The study found that a natural bile acid called TCA, which increases when you eat a little lard, helps fat cells burn fat and turns immune cells into a type that reduces inflammation—exactly what the claim says.

Similar Assertions

When mice had more taurocholic acid in their blood, their fat cells turned on more genes that help break down fat.

When scientists added TCA (a bile acid) to fat cells and immune cells in a dish, it made the fat cells store less fat and the immune cells become less inflamed, mimicking what was seen in mice that ate lard.

83%

Mice that ate lard had more of a bile acid called TCA in their blood, and the more TCA they had, the smaller their fat cells and the more their bodies were breaking down fat and calming inflammation.

80%

Mice that ate a moderate amount of lard had more of a substance called taurocholic acid in their blood than mice that ate other oils.
